2017–18 Chelsea F.C. season

The 2017–18 season was Chelsea's 104th competitive season, 29th consecutive season in the top flight of English football, 26th consecutive season in the Premier League and 112th year in existence as a football club. The season covered the period from 1 July 2017 to 30 June 2018.

The season was the first since 1997–98 without former club captain John Terry, after he departed to Aston Villa on a free transfer following 22 years with the club. Chelsea returned to the UEFA Champions League after a single season's absence and entered the Premier League season as defending champions. The season was also Chelsea's first under the new kit deal with Nike, the most lucrative commercial deal in the history of the club.

On 18 July, first-team manager Antonio Conte was rewarded for his successful first season at Chelsea with a new two-year contract, serving to replace the previous contract and offer improved terms to the Italian. After signing, Conte said, "I am very happy to have signed a new contract with Chelsea. We worked extremely hard in our first year to achieve something amazing, which I am very proud of. Now we must work even harder to stay at the top. The Chelsea fans have given me so much support since I arrived here one year ago and it is important we continue to succeed together." Along with the new contract, two new members of Conte's backroom team were announced: Paolo Vanoli and Davide Mazzotta. Vanoli will serve as first-team assistant while Mazzotta will serve as both an assistant and a player analyst.

On 19 July, Chelsea announced a transfer fee had been agreed to with Real Madrid for the transfer of striker Álvaro Morata, subject to Morata agreeing to personal terms and passing a medical with Chelsea. The Spanish international forward helped Real Madrid defend their UEFA Champions League title in 2016–17, scoring 20 goals in all competitions across the 2016–17 season. The initial transfer fee was reported to be around £58 million, which could increase to £70 million with add-ons, which would make him Chelsea's new record-high signing, surpassing the £50 million transfer fee paid for Fernando Torres in January 2011. The signing was officially announced two days later on 21 July, with Morata signing a five-year contract with the Premier League champions. He joined the Chelsea squad on their pre-season tour in Asia.

August

On 2 August, Mario Pašalić signed a four-year contract extension and joined Russian champions Spartak Moscow on a season-long loan.

On 6 August, Chelsea lost the Community Shield 4–1 on penalties to Arsenal after drawing 1–1 in normal time.

On 11 August, young English midfielder Lewis Baker signed a new five-year contract with Chelsea, simultaneously completing a season-long loan move to Championship club Middlesbrough.

On 12 August, Chelsea suffered a nightmare start to their Premier League title defence, losing 3–2 at home to Burnley, who had only won once away from home in the previous season. Chelsea's performance was marred by two of their players receiving red cards, the first being captain Gary Cahill in the early stages of the game, and the second being Cesc Fàbregas towards the closing stages of the match. ''The Blues'' fought back from 3–0 down with goals from debutant Álvaro Morata and David Luiz, but ultimately lost the match. Such defeat was the second ever for a Premier League holder. The first was Leicester City's defeat against Hull City the previous season, which was an away match for Leicester. The home defeat would also mark the first time since the 1998–99 season that Chelsea had lost the opening match of a Premier League season.

On 20 August, Chelsea bounced back from their disappointing defeat with a 2–1 away victory over Tottenham Hotspur at their temporary home, Wembley Stadium. Marcos Alonso scored a double, his first goal being a free-kick and his second a strike late in the match, while Spurs scored through an own goal from Michy Batshuayi. The win for Chelsea condemned Tottenham to defeat in their first home match of the season and their first at Wembley in the Premier League.

On 25 August, Nigerian defender Kenneth Omeruo signed a new three-year contract with Chelsea, simultaneously completing a season-long loan move to Turkish club Kasımpaşa, where he had previously been on loan at in the 2015–16 campaign.

On 27 August, Chelsea won their first Premier League home match of the 2017–18 season after defeating Everton 2–0 in a dominant display that ''the Blues'' could have won by more goals. Fàbregas opened the scoring in the 27th minute, coolly clipping into the bottom corner and past goalkeeper Jordan Pickford with the help of Morata, who claimed his second assist of the season. Morata would later add to Chelsea's goal tally with a header in the 40th minute, scoring his second league goal of the season. ''The Blues'' had many opportunities throughout the match to extend their lead, but ultimately won comfortably in a convincing performance that lifted them to sixth in the table after three matches.

On 28 August, young Ivorian attacker Jérémie Boga signed a new three-year contract with Chelsea, and also joined Championship club Birmingham City on a season-long loan.

Deadline day (31 August)

Chelsea signed two players on transfer deadline day: Italian right-back Davide Zappacosta from Torino, who joined for a reported £23 million transfer fee; and Leicester City midfielder Danny Drinkwater, who arrived for an undisclosed fee and signed a five-year contract with ''the Blues''.

In spite of several signings arriving at the club, it was a turbulent deadline day for ''the Blues'', in that several of their transfer targets were missed. The most notable of these was Chelsea's attempt to sign Everton midfielder Ross Barkley, agreeing a fee with Everton only for Barkley to reject the move. (Barkley would later join Chelsea in the January transfer window.) Another English transfer target, Arsenal midfielder Alex Oxlade-Chamberlain, also rejected a move to Chelsea after a fee had been agreed between the two clubs, with Oxlade-Chamberlain instead choosing a move to Liverpool on deadline day. ''The Blues'' had also reportedly been close to signing Swansea City striker Fernando Llorente at one point throughout deadline day, only to miss out on signing him to their rivals Tottenham.

September

On 1 September, Loïc Rémy left the club to sign for La Liga club Las Palmas on a two-year contract for a reported free transfer.

On 9 September, Chelsea earned a 2–1 away victory at Leicester City, making it a third Premier League victory in a row. N'Golo Kanté scored the second goal for ''the Blues'' against his former club. Davide Zappacosta made his debut for Chelsea while Eden Hazard returned from injury, coming on as a substitute.

On 12 September, Chelsea marked their return to the UEFA Champions League with a 6–0 thrashing of Azerbaijani champions Qarabağ, who made their first ever appearance in Europe's elite competition. Goals from Pedro, César Azpilicueta, Tiémoué Bakayoko, Michy Batshuayi, as well as a goal from Zappacosta on his first start for Chelsea and an own goal by Qarabağ player Maksim Medvedev, sent ''the Blues'' to the top of their group after the first round of fixtures.

On 17 September, Chelsea hosted rivals Arsenal at Stamford Bridge, who managed to emerge with a point by drawing 0–0 with ''the Blues''. It was a frustrating match for Chelsea, who created several opportunities to score but could not find a cutting edge against a well-drilled Arsenal side. The game was also marred by David Luiz receiving a red card in the second half for a high tackle on Sead Kolašinac, with the defender set to miss Chelsea's next three matches as a result. His red card amounts to Chelsea's third red card of the season. The result sees ''the Blues'' remaining in third place, three points behind joint leaders Manchester United and Manchester City.

On 20 September, Chelsea hosted Nottingham Forest in the third round of the EFL Cup, defeating the Championship club 5–1 to advance to the next round. Amongst the goalscorers was Batshuayi, who completed a hat-trick with a goal in the first half and two further goals in the second half. Kenedy and Charly Musonda also got on the scoresheet and youngster Ethan Ampadu made his first senior Chelsea appearance as a second-half substitute.

On 21 September, the long-protracted transfer saga surrounding exiled striker Diego Costa came to an end as Chelsea agreed a fee with Atlético Madrid for his transfer, to be completed in January after the expiry of the Spanish club's transfer ban. He left Chelsea having scored 58 goals in 120 appearances for ''the Blues'', including 20 in the Premier League last season as Chelsea won the title.

On 23 September, Chelsea earned a fourth Premier League victory in five matches after thrashing Stoke City 4–0 away. Álvaro Morata opened the scoring for ''the Blues'', with Pedro adding a second before half-time. Morata completed a hat-trick in the second half, Chelsea's first Premier League hat-trick since 2014, to keep ''the Blues'' in third position and within three points of the two Manchester clubs at the top of the table.

On 27 September, Chelsea beat Atlético Madrid 2–1 away in a Champions League group stage match, making history in the process by becoming the first ever English club to defeat Atlético away from home in a European competition. Chelsea fell behind late in the first half after David Luiz conceded a penalty, which Antoine Griezmann converted. Morata leveled proceedings early in the second half with a header. The match looked to be finishing as a draw until Batshuayi snatched a winner for Chelsea at the death. The result sees ''the Blues'' go top of Group C, four points ahead of Atlético and Roma after two matches.

On 30 September, three days after their Champions League heroics, Chelsea lost 1–0 at Stamford Bridge to league leaders Manchester City in a very poor performance that culminated in Chelsea only having two shots on target in the entire match. The defeat saw the gap between the two sides widen to six points, with Chelsea slipping into fourth.

October

On 14 October, in their first league match after the international break, Chelsea fell to a very poor 2–1 away defeat against bottom Premier League side Crystal Palace. The home side scored their first goals and earned their first points of the season after losing their opening seven fixtures without scoring. An own goal from César Azpilicueta opened the scoring early in the first half before Tiémoué Bakayoko leveled proceedings shortly after. Palace would go on to win the match with a goal from the returning Wilfried Zaha. Chelsea were without key players N'Golo Kanté and Álvaro Morata, with Kanté picking up a hamstring injury during the international break and Morata suffering the same injury against Manchester City. Chelsea lost back-to-back league fixtures for the first time in a year, when they lost to Liverpool and Arsenal.

On 18 October, Chelsea drew 3–3 at home against Roma in the UEFA Champions League. Chelsea, having led 2–0 following goals from David Luiz and Eden Hazard, caved in to Roma's Edin Džeko and Aleksandar Kolarov, who between them scored three goals. With a late goal from Hazard to equalise for the home side, Chelsea dropped their first points in the 2017–18 UEFA Champions League group stage.

On 21 October, Chelsea enjoyed a 4–2 come-from-behind victory over Watford. Following a Pedro goal, Watford found themselves 2–1 up through goals from Abdoulaye Doucouré and Roberto Pereyra. However, Michy Batshuayi came off the bench to score a brace on either side of a César Azpilicueta winner. The win snapped a four-game winless streak in all competitions for Chelsea.

On 25 October, Chelsea progressed past the round of 16 in the EFL Cup by defeating Everton 2–1 in the first match for Everton interim manager David Unsworth. Goals from Willian and Rüdiger rendered a late Dominic Calvert-Lewin goal a mere consolation.

On 28 October, in the Premier League, Chelsea narrowly defeated AFC Bournemouth 1–0 away from home. A goal from Eden Hazard sealed the points in a tight encounter.

On 31 October, in their final October fixture, Chelsea fell to a poor 3–0 away defeat to Roma in the Champions League and became the first English team to lose a Champions League fixture in 2017–18 as a result. ''The Blues'' fell behind after 39 seconds from a goal by Stephan El Shaarawy, and they never looked like recovering after he scored a second in the 36th minute. Chelsea had more shots throughout the match, but a third Roma goal scored by Diego Perotti in the second half sealed the contest. Results elsewhere kept Chelsea in the top two of their group, with Atlético Madrid drawing with Qarabağ.

November

On 5 November, Chelsea got the month off to a good start as they defeated long-time competitive rivals Manchester United 1–0 at Stamford Bridge, courtesy of a header from Álvaro Morata, scoring his first goal for the club since September. It was former ''Blues'' manager José Mourinho's third-straight loss at Stamford Bridge since he became United manager. The victory lifted Chelsea into fourth place and within one point of Manchester United in second.

On 18 November, in Chelsea's first match after the international break, they dispatched West Bromwich Albion 4–0 away from home in the Premier League in a commanding performance that saw opposite number Tony Pulis sacked just days after the match. Álvaro Morata put Chelsea in front on 17 minutes, his eighth league goal of the season, while an Eden Hazard double either side of half-time and a first half goal from Marcos Alonso sealed a comfortable win for Chelsea. The victory was Chelsea's fourth successive league win, while West Brom remained without a win in all competitions since 22 August, a run of 11 matches. Chelsea moved up to third, one point behind Manchester United.

On 22 November, Chelsea sealed their progression to the knockout stage of the Champions League after defeating Qarabağ 4–0 away in a 5,000-mile trip to Azerbaijan. Two goals from Willian, as well as spot-kicks from Eden Hazard and Cesc Fàbregas, confirmed ''the Blues'' will finish in the top two of Group C with a match to spare.

On 25 November, just three days after travelling to Azerbaijan, Chelsea earned a 1–1 league draw at Anfield against Liverpool. Former Chelsea player Mohamed Salah opened the scoring for Liverpool with a close-range finish just after the hour mark, while Willian, continuing his good run of form, struck in the 85th minute through what appeared to be a cross looping over goalkeeper Simon Mignolet and into the far corner. The result was a repeat scoreline of last season's 1–1 draw at Anfield, ensuring Chelsea remained unbeaten in their past seven visits to Anfield, a run stretching back to 2013. However, the draw left Chelsea three points behind Manchester United in second and eight points behind league leaders Manchester City.

On 27 November, former Chelsea academy manager Dermot Drummy died aged 56. Drummy won the 2010 FA Youth Cup whilst working at the club and later served as reserve team manager before taking the role of international head coach in June 2014. Former Chelsea youth players that had been coached under him paid tribute to Drummy, including Nathan Aké, Nathaniel Chalobah, Patrick Bamford and Ruben Loftus-Cheek.

On 29 November, Chelsea capped off the month of November with a hard-fought 1–0 league victory against struggling Swansea City. Chelsea dominated the game but had to wait until the 55th minute for the breakthrough, with defender Antonio Rüdiger heading in his first Premier League goal after N'Golo Kanté's shot was deflected into his path. The match was marred by an incident involving manager Antonio Conte and match official Neil Swarbrick, with the Italian spending the whole of the second half watching from a television feed in the dressing room after disputing Swarbrick's decision not to award a corner when the match was goalless. Conte later apologised for his conduct, saying, "I was frustrated. For sure I made a mistake. During the game I suffer. With my players I suffer. It's a pity." Chelsea remained third in the table, three points behind Manchester United in second and 11 points behind runaway leaders Manchester City.

December

On 2 December, Chelsea defeated newly promoted Newcastle United 3–1 at Stamford Bridge. Dwight Gayle put the visitors in front after 12 minutes, but Newcastle's lead was short lived as Eden Hazard and Álvaro Morata struck in the first half to send ''the Blues'' 2–1 up at the break. Hazard scored his second goal of the game in the second half, a chipped penalty after Matt Ritchie fouled Victor Moses in the area. The result kept Chelsea in touch with the two Manchester clubs after they had both won in the same gameweek, with ''the Blues'' remaining third, but now three points ahead of Liverpool in fourth.

On 5 December, Chelsea drew 1–1 against Atlético Madrid on the final matchday of the Champions League. Saúl's header opened the scoring in the 56th minute before a Stefan Savić own goal leveled the scoreline. The result saw Roma surpass Chelsea for the top spot of Group C via the head-to-head tiebreaker. The draw also caused Atlético to fail to progress to the knockout stages of the Champions League for the first time since they failed to qualify outright, in 2012–13.

On 9 December, Chelsea's unbeaten league run since October came to an end after they lost 1–0 to West Ham United at the London Stadium. Marko Arnautović scored for West Ham early in the first half, and Chelsea struggled to get a foothold in the game as they gave David Moyes his first league win in charge of West Ham. Following the match, Antonio Conte admitted defeat in Chelsea's attempt to retain their Premier League crown, saying, "When you tell the truth, this is the truth. Now we have 11 points less than Manchester City ho had a game in hand In 16 games they won 15 and drew one. In 17 games we lost four. When you have a competitor like City and every game they are winning, it is very difficult to think you can fight for the title."

On 12 December, Chelsea returned to winning ways in the Premier League in a dominant 3–1 away win against newly promoted Huddersfield Town. Goals from Tiémoué Bakayoko, Willian and Pedro rendered a late Laurent Depoitre strike mere consolation.

On 16 December, Chelsea defeated Southampton 1–0 at Stamford Bridge, courtesy of a Marcos Alonso free-kick, somewhat controversially occurring 30 seconds past the two allotted minutes of added time in the first half. In an otherwise extremely tight affair, Charlie Austin had the best chance for the away side with his first touch of the ball after he came on as a substitute. However, one goal proved to be enough for ''the Blues'' to secure all three points.

On 20 December, Chelsea defeated AFC Bournemouth 2–1 in the EFL Cup quarter-finals. Conte rotated the team heavily, making eight changes from the side that beat Huddersfield. Ethan Ampadu was named man of the match after an admirable performance at centre-back, despite an early tackle that injured Bournemouth striker Jermain Defoe. Chelsea took the lead through Willian, with Cesc Fàbregas and Kenedy heavily involved in the build-up. Chelsea dominated the majority of the first half, but Bournemouth were reinvigorated following the half-time break. Their efforts finally paid off in the 90th minute when Dan Gosling curled in from outside of the 18-yard box. The match looked certain to go into extra time but following the kick-off, substitute Álvaro Morata almost immediately scored the winner. Following the match, Chelsea were drawn against Arsenal in the semi-finals. In the other match, high-flying Manchester City were drawn against Bristol City, who shockingly defeated their next opponent's city rivals, Manchester United.

On 23 December, Chelsea visited Goodison Park and drew 0–0 against Everton. With striker Álvaro Morata suspended due to yellow card accumulation, Chelsea played Eden Hazard as a false nine. However, Chelsea lacked many scoring opportunities and ultimately were made to pay as Everton won a point in their final home match of the year.

On 26 December, Chelsea took on Brighton & Hove Albion at Stamford Bridge. Following a quiet first half in which the only clear-cut chance came from Tiémoué Bakayoko, Chelsea scored 53 seconds after the break, courtesy of an Álvaro Morata goal, assisted by César Azpilicueta. It was the sixth time that the Spaniards linked up during the season to score. Later on, Marcos Alonso headed in from a corner as ''the Blues'' comfortably won 2–0 to extend their unbeaten run on Boxing Day to 14 matches.

On 30 December, Chelsea played their final match of 2017 against Stoke City, winning with ease 5–0. Due to fixture congestion in the festive period, Chelsea rotated their lineup slightly, resting Eden Hazard and Cesc Fàbregas. However, Stoke City started a completely rotated lineup, with manager and former Chelsea player Mark Hughes prioritizing the upcoming Newcastle game. After two goals in the opening ten minutes from Antonio Rüdiger and Danny Drinkwater, Chelsea looked set to dominate the match, and did so, scoring three more goals through Pedro, Willian and Davide Zappacosta. Chelsea ended the calendar year in second place, one point ahead of Manchester United and 14 points behind runaway leaders Manchester City.

January

On 1 January 2018, Diego Costa officially departed the club and signed for Atlético Madrid.

On 3 January, Chelsea took on Arsenal in a thrilling encounter which ended 2–2 away at the Emirates Stadium. Jack Wilshere opened the scoring after the break, following an end-to-end first half, headlined by a clear-cut chance missed by Álvaro Morata in the 15th minute. However, following the opener, Chelsea scored twice, once courtesy of an Eden Hazard penalty, and again in the 84th minute, when Marcos Alonso scored what looked to be the winner. However, in the 92nd minute, Héctor Bellerín scored a late equaliser into the bottom left corner of the goal, earning both teams one point. In the last minute of stoppage time, Morata missed another clear-cut chance, and substitute Davide Zappacosta lashed the rebound goalwards, only to see it bounce back off of the crossbar with virtually the last kick of the match. Following the match, Morata was heavily criticised due to his poor performance.

On 5 January 2018, Chelsea signed 24-year-old Englishman Ross Barkley from Everton for a reported £15 million. He was assigned the number 8 shirt, previously occupied by Oscar and Frank Lampard. Barkley did not make any appearances for Everton in the 2017–18 season, so he was eligible to play in all of Chelsea's competitions. Following signing, Barkley said, "To be given a fresh start at a new club like Chelsea, it's unbelievable for me. I'm looking forward to continuing where I left off at the end of last season and hoping to improve and add more goals to my game."

On 30 January 2018, Chelsea announced the signing of 23-year-old Brazilian–Italian Emerson from Roma for a reported £17 million; he was assigned the number 33 shirt.

On 31 January 2018, Chelsea announced the signing of Olivier Giroud from Arsenal for £18 million; he will wear the number 18 shirt.

February

On 5 February, Chelsea defeated by Watford 4–1 at Vicarage Road. Troy Deeney opened the scoring line with a goal from penalty after being fouled by Bakayoko; Bakayoko received a second yellow card after 30 minutes play. The Blues played an hour with ten men after Bakayoko's red card capped a dreadful individual 30-minute performance in which he gifted Watford four chances. ''The Hornets'', who had won only one of their previous 12 Premier League matches, led as Gerard Deulofeu was fouled by keeper Thibaut Courtois in the box and Deeney open scored through the penalty. Chelsea, who brought on Olivier Giroud for a debut in the second half, scored an undeserved equaliser when Eden Hazard curled home brilliantly from 25 yards. However, two minutes later, Daryl Janmaat scored a fantastic goal of his own when he cut in from the right wing, played a one-two with Roberto Pereyra and beat another couple of defenders before scoring with his weaker left foot. Deulofeu added another when he ran from halfway before his shot was slightly deflected by Gary Cahill and Pereyra scored a fourth from Abdoulaye Doucouré's through-ball. Deulofeu got a Man of The Match in this campaign.

On 12 February, Chelsea bounced back from their disappointing defeat with a 3–0 home victory over West Bromwich Albion. Hazard exchanged passes with Olivier Giroud before giving Chelsea a first-half lead and, after Victor Moses slid home a second after the break, sealed victory with a powerful drive in the 71st minute. The win took ''the Blues'' one point ahead of fifth-placed Tottenham. Hazard received the Man of the Match award in this match, with his two goals against West Brom.

On 20 February, Chelsea drew Barcelona 1–1 at Stamford Bridge in the first leg of the UEFA Champions League Round of 16. ''The Blues'' had subdued Messi and Willian struck the woodwork twice in the first half before a fine low finish from the edge of the area made it third time lucky for the Brazilian to give Chelsea a deserved lead after 62 minutes. Barcelona had barely threatened but a misplaced pass from Andreas Christensen gave Andrés Iniesta the opportunity to allow Messi to end his 730-minute drought against Chelsea with a crisp left-foot drive 15 minutes from time.

On 22 February, Mitchell Beeney was loaned out to Ireland top division club Sligo Rovers until 30 June 2018.

On 25 February, Chelsea lost 2–1 away at Old Trafford in the Premier League against Manchester United. ''The Red Devils'' came from behind after Willian started and finished a flowing move to give Chelsea the lead in the first half. United pulled level before the break with striker Romelu Lukaku getting in front of Marcos Alonso to score against his former club for the first time. Lukaku then set-up Jesse Lingard to head home with 15 minutes left, after which Chelsea's Álvaro Morata had a goal incorrectly disallowed for offside. The defeat left ''the Blues'' in fifth place after Tottenham defeated Crystal Palace 1–0 earlier that day. A run of just one win in their past four league matches, coupled with Spurs' ten-game unbeaten streak, bumped Chelsea out of the Champions League places with ten matches to play.

March

On 4 March, Chelsea again lost in the Premier League, falling 1–0 to Manchester City away at the Etihad. ''The Blues'' failed to recorded a shot on target in the match as Bernardo Silva's goal less than one minute into the second half sealed the match and pushed City 18 points clear at the top of the league table and closer to the title. Chelsea did not register a single shot on target, leaving Manchester City keeper Ederson a virtual bystander, as he was even able to watch Alonso's timid shot drift wide with seconds left. After the loss, Chelsea fell five points adrift of Tottenham for fourth place in the league table.

On 10 March, Chelsea bounced back with a 2–1 home victory over Crystal Palace. Willian opened the scoring for the hosts — aided by a deflection off Palace defender Martin Kelly — with a shot that crept inside the left-hand post. Chelsea spurned several excellent openings before doubling their advantage, again thanks to significant chunk of good fortune. Kelly was again involved, with the former Liverpool player initially doing well to clear Davide Zappacosta's drive off his own goal line only for the ball to ricochet off ''Eagles'' goalkeeper Wayne Hennessey and strike Kelly before entering the net. Eden Hazard had a goal disallowed for offside and Chelsea's profligacy threatened to give Roy Hodgson's team a route back into the match. Patrick van Aanholt's late goal briefly raised their hopes, but Conte's side held on with Palace remaining in the bottom three. After defeats to both Manchester clubs had weakened their grip on a Champions League place, this represented a welcome three points for Chelsea, who dominated proceedings from start to finish.

In the away leg of the UEFA Champions League following a 1–1 draw at home against Barcelona, Chelsea fell behind after just 128 seconds after Lionel Messi shot through the legs of Thibaut Courtois from a tight angle. Messi then set-up Ousmane Dembele to hammer home the second after Cesc Fàbregas lost possession. Marcos Alonso hit the post for Chelsea with a free-kick before Messi's 100th Champions League goal — following a mistake by César Azpilicueta — took the hosts out of sight. Alonso was then denied a penalty after a challenge by Gerard Piqué as ''Barça'' joined La Liga rivals Real Madrid and Sevilla in the competition's quarter-final draw.

On 15 March, Chelsea announced that they had reached settlement in last right of light issue holding up stadium development.

After Chelsea's elimination from the Champions League, the club defeated Leicester City 1–2 away at the King Power Stadium in the FA Cup. Just before half-time, Álvaro Morata took Willian's pass in his stride to beat Leicester goalkeeper Kasper Schmeichel. Jamie Vardy made amends for a poor headed miss when he pounced in a goalmouth scramble for a 76th-minute equaliser for ''the Foxes''. The decisive moment came just before the interval in extra time when Chelsea substitute Pedro beat the onrushing Schmeichel to N'Golo Kante's cross and headed in the winner. With the victory, Chelsea qualified for the competition's semi-finals. Chelsea play this match after they're knocked from Champions League against Barcelona 3–0 in Round of 16. Barcelona won 4–1 on Aggregate.

April

On 1 April, Chelsea lost at home against London rivals Tottenham. Álvaro Morata headed-in a Victor Moses cross to give the hosts the lead. However, Christian Eriksen hit a stunning equaliser on the stroke of half-time, his dipping effort from 25 yards dropping just under the bar and over a stranded Willy Caballero. Dele Alli then took centre stage in the second half, putting Tottenham ahead just after the hour mark when he produced a sublime first touch to bring Eric Dier's ball under control before slotting beyond Caballero. Alli was well-placed four minutes later to stab in following a goalmouth scramble and wrap-up a win that moved fourth-placed Spurs eight points clear of Chelsea, who remained in the fifth position.

On 8 April, Chelsea faced West Ham at Stamford Bridge. Javier Hernández's second-half equaliser boosted West Ham's Premier League survival prospects and damaged Chelsea's slim hopes of finishing in the top-four on an emotional day at Stamford Bridge, as the previous Wednesday, former Chelsea midfielder and assistant coach Ray Wilkins passed away at age 61. Prior to kick-off, there was a minute's applause for Wilkins, with the Chelsea players also donning black armbands in his memory. In the match, César Azpilicueta had prodded the hosts ahead following Álvaro Morata's knock-down, with Azpilicueta dedicating his goal to Wilkins. However, just three minutes after entering the match as a substitute, Hernández struck his ninth career goal against ''the Blues'' to earn a point for ''the Hammers''. The Mexican's effort, driven into the corner after Marko Arnautović's fine cut-back, moved David Moyes' club six points clear of the relegation places. It was only West Ham's third touch inside the Chelsea's penalty area. In contrast, Antonio Conte's men — who were in fifth position but ten points behind Tottenham and Liverpool — had 23 shots on goal and were good value for their lead for long periods, including having two would-be goals from Álvaro Morata called-back for offside and several quality chances turned aside by goalkeeper Joe Hart. The win for Moyes as a manager ended a personal 15-match winless run at Stamford Bridge.

On 14 April, Chelsea returning to the winning track with a thrilling 3–2 late comeback victory against Southampton at St. Mary's Stadium. Dušan Tadić's opener — a placed effort following Ryan Bertrand's marauding run — and Polish defender Jan Bednarek's left-footed shot looked to lift ''the Saints'' out of the bottom three with manager Mark Hughes seemingly on course for a first league victory as Southampton manager since arriving on 14 March. However, after coming on a substitute, Olivier Giroud scored his first Premier League goal for Chelsea, a 70th-minute header. Just five minutes later, Eden Hazard scored a left-footed finish, followed by a second goal from Giroud coming in the 78th minute, the eventual match-winner. The victory saw Chelsea move within seven points of fourth-placed Tottenham.

On 19 April, Chelsea defeated Burnley 2–1 away at Turf Moor. Kevin Long's own goal sent Conte's men on their way in the first half. However, Ashley Barnes deflected Jóhann Berg Guðmundsson's wayward shot to equalise for Burnley. Victor Moses' right-footed shot into the bottom corner proved decisive and ensured ''the Blues'', who trailed fourth-placed Tottenham by ten points the previous week, narrowed the gap to five points. Sean Dyche's Burnley remain seventh and on course for 2018–19 UEFA Europa League qualification with an eight-point advantage over Leicester City, sitting in eighth.

On 21 April, Chelsea reached the FA Cup Final after defeating Southampton 2–0 at Wembley Stadium. Chelsea striker Olivier Giroud received the ball from Eden Hazard and jinked his way past two Southampton players in a crowded area before he stabbed the ball home. With ten minutes to play, Giroud was replaced by Álvaro Morata, who ensured progression with Chelsea's second goal after he headed-in at the back post from a César Azpilicueta cross. Southampton went close with Nathan Redmond's low drive from distance, while Charlie Austin hit the post. The victory meant Chelsea manager Antonio Conte would match-up against managerial adversary José Mourinho at Wembley on 19 May against Manchester United.

On 28 April, Chelsea take against Swansea at Liberty Stadium, Chelsea returned to playing in the league after playing in the FA Cup last week. Fabregas' curling finish was a fitting way to bring up his half-century of goals in the Premier League, but it was Hazard's clinical exploitation of a Swansea error that made it, pouncing on Andy King's sloppy loss of possession, weaving his way forward and picking out the right pass. Antonio Rudiger may well have given Hazard his second assist soon after, only for the defender to spurn the chance at the far post following a corner. Hazard was at the heart of Chelsea's best threatening moves and made the most of some naive defending as Swansea afforded him plenty of space for surging runs on the counter. Chelsea – who had skimmed the top of the bar after Alfie Mawson cleared an Olivier Giroud header – did not see goalkeeper Thibaut Courtois really tested until the final 15 minutes, when Andre Ayew fizzed in a shot. Kyle Naughton, Tom Carroll and Wayne Routledge also went close. Swansea claimed for a penalty when Gary Cahill challenged Nathan Dyer, with the Chelsea defender also involved in a clash with Jordan Ayew in injury time after a late barge from the Ghanaian.

May

On 6 May on Gameweek 37, Chelsea beat Liverpool at the Bridge 1–0 with a header from Giroud in the 32nd minute after receiving an assist from Moses. Giroud expertly headed in Moses' cross in the first half after the visitors had dominated possession and failed to capitalize. Chelsea remain in fifth but move within three points of third-placed Liverpool. With two games remaining to Liverpool's one, Chelsea can move level on points with the Champions League finalists when they face Huddersfield on Wednesday. Liverpool had more than 66% possession in the first half and created plenty of chances – the best falling to Mane, who was denied twice by Thibaut Courtois – but it was Chelsea who came closest. Bakayoko's header bounced inches wide just moments before Giroud leapt high to nod home Moses' cross. And Fabregas' smart run in behind the defence created an opening which he could not convert from a tight angle. Chelsea had the best chances of the second half too. Hazard almost danced his way through before Rudiger's header was ruled out for offside and Alonso's volley flew inches wide.

On 13 May, at the last Gameweek, Chelsea claimed a 3–0 defeat at St James' Park. The Blues had a chance of sneaking into the top four by beating the Magpies, but Liverpool's victory over Brighton means they finish fifth and must settle for a Europa League spot. A barrage at goal from the hosts forced visiting goalkeeper Thibaut Courtois to make sharp saves from the impressive Jonjo Shelvey and Mohamed Diamé. But Ayoze Pérez poked home twice in the second period as his side finished the season in 10th position. Chelsea's best chance fell to striker Olivier Giroud, but the Frenchman's acrobatic effort was tipped away by goalkeeper Martin Dubravka. Shelvey gets an MOTM in this match.

On 19 May, in the 2018 FA Cup Final, FA Cup Final, Chelsea lifted the FA Cup after beating Manchester United F.C, Manchester United 1–0 at Wembley Stadium, Wembley with a single-goal from Eden Hazard's penalty at 22 minutes after Phil Jones (footballer, born 1992), Phil Jones fouled Hazard. Chelsea won their 8th FA Cup Trophy and their first since 2012.
