Soccer

Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players who primarily use their feet to propel the ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposition by moving the ball beyond the goal line into a rectangular framed goal defended by the opposing side. Traditionally, the game has been played over two 45 minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries, it is considered the world's most popular sport.

The game of association football is played in accordance with the Laws of the Game, a set of rules that has been in effect since 1863 with the International Football Association Board (IFAB) maintaining them since 1886. The game is played with a football that is in circumference. The two teams compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. When the ball is in play, the players mainly use their feet, but may use any other part of their body to control, strike or pass the ball apart from their hands or arms. Only the goalkeepers may use their hands and arms, and only then within the penalty area. The team that has scored more goals at the end of the game is the winner. Depending on the format of the competition, an equal number of goals scored may result in a draw being declared, or the game goes into extra time or a penalty shootout.

Internationally, association football is globally governed by FIFA. The national associations are responsible for managing the game, both professionally and at an amateur level, in their own countries and coordinating competitions in accordance with the Laws of the Game. The most senior and prestigious international competitions are the men's FIFA World Cup and the FIFA Women's World Cup. The men's World Cup is the most-viewed sporting event in the world, surpassing the Olympic Games. The top five European men's leagues are the Premier League (England), La Liga (Spain), Bundesliga (Germany), Serie A (Italy), and Ligue 1 (France). Attracting most of the world's best players, each of the leagues has a total wage cost in excess of £600 million/€763 million/US$1.185 billion.

The final of the men's tournament has been, in recent years, the most-watched annual sporting event in the world. Women's association football has historically seen opposition from national associations severely curbing its development, several outlawing it completely. Restrictions started to be reduced in the 1980s and the first women's World Cup was the 1991 FIFA Women's World Cup in China with only 12 teams from the respective 6 confederations. By the 2019 FIFA Women's World Cup in France, this had increased to 24 national teams and a record-breaking 1.12 billion viewers watched the competition. The two most prestigious competitions in European club football are the UEFA Champions League and UEFA Women's Champions League, which attract an extensive television audience throughout the world.

Name

Football is one of a family of football codes, which emerged from various ball games played worldwide since antiquity.

Within the English-speaking world, association football is now usually called "football" in Great Britain and most of Ulster in the north of Ireland, whereas people usually call it "soccer" in regions and countries where other codes of football are prevalent, such as Australia, Canada, South Africa, most of Ireland (excluding Ulster) and the United States. A notable exception is New Zealand, where in the first two decades of the 21st century, under the influence of international television, "football" has been gaining prevalence, despite the dominance of other codes of football, namely rugby union and rugby league. In Japan, the game is also primarily called sakkā (サッカー), derived from "soccer".

The term ''soccer'' comes from Oxford "-er" slang, which was prevalent at the University of Oxford in England from about 1875, and is thought to have been borrowed from the slang of Rugby School. Initially spelled ''assoccer'', it was later reduced to the modern spelling. This form of slang also gave rise to ''rugger'' for rugby football, ''fiver'' and ''tenner'' for five pound and ten pound notes, and the now-archaic ''footer'' that was also a name for association football. The word ''soccer'' arrived at its final form in 1895 and was first recorded in 1889 in the earlier form of ''socca.''

History

Kicking ball games arose independently multiple times across multiple cultures. ' and ' were Greek ball games. An image of an ' player depicted in low relief on a stele of in the National Archaeological Museum of Athens appears on the UEFA European Championship trophy. Athenaeus, writing in 228 CE, mentions the Roman ball game '. ' and ' were played involving hands and violence. They all appear to have resembled rugby football, wrestling and volleyball more than what is recognizable as modern football. As with pre-codified mob football, the antecedent of all modern football codes, these three games involved more handling the ball than kicking.

The Chinese competitive game ' (, literally "kick ball") resembles modern association football. ' players could use any part of the body apart from hands and the intent was kicking a ball through an opening into a net. During the Han dynasty (206 BCE – 220 CE), ' games were standardised and rules were established.

Association football in itself does not have a classical history. Notwithstanding any similarities to other ball games played around the world, FIFA has recognised that no historical connection exists with any game played in antiquity outside Europe. The modern rules of association football are based on the mid-19th century efforts to standardise the widely varying forms of football played in the public schools of England. The history of football in England dates back to at least the eighth century.

The Cambridge rules, first drawn up at the University of Cambridge in 1848, were particularly influential in the development of subsequent codes, including association football. The Cambridge rules were written at Trinity College, Cambridge, at a meeting attended by representatives from Eton, Harrow, Rugby, Winchester and Shrewsbury schools. They were not universally adopted. During the 1850s, many clubs unconnected to schools or universities were formed throughout the English-speaking world, to play various forms of football. Some came up with their own distinct codes of rules, most notably the Sheffield Football Club, formed by former public school pupils in 1857, which led to the formation of a Sheffield FA in 1867. In 1862, John Charles Thring of Uppingham School also devised an influential set of rules.

These ongoing efforts contributed to the formation of The Football Association (The FA) in 1863, which first met on the morning of 26 October 1863 at the Freemasons' Tavern in Great Queen Street, London. The only school to be represented on this occasion was Charterhouse. The Freemasons' Tavern was the setting for five more meetings between October and December, which eventually produced the first comprehensive set of rules. At the final meeting, the first FA treasurer, the representative from Blackheath F.C., withdrew his club from the FA over the removal of two draft rules at the previous meeting: the first allowed for running with the ball in hand; the second for obstructing such a run by hacking (kicking an opponent in the shins), tripping and holding. Other English rugby clubs followed this lead and did not join the FA, and instead in 1871 formed the Rugby Football Union. The eleven remaining clubs, under the charge of Ebenezer Cobb Morley, went on to ratify the original thirteen laws of the game. These rules included handling of the ball by "marks" and the lack of a crossbar, rules which made it remarkably similar to Victorian rules football being developed at that time in Australia. The Sheffield FA played by its own rules until the 1870s, with the FA absorbing some of its rules until there was little difference between the games.

The world's oldest football competition is the FA Cup, which was founded by the footballer and cricketer Charles W. Alcock, and has been contested by English teams since 1872. The first official international football match also took place in 1872, between Scotland and England in Glasgow, again at the instigation of Alcock. England is also home to the world's first football league, which was founded in Birmingham in 1888 by Aston Villa director William McGregor. The original format contained 12 clubs from the Midlands and Northern England.

The Laws of the Game are determined by the International Football Association Board (IFAB). The board was formed in 1886 after a meeting in Manchester of the Football Association, the Scottish Football Association, the Football Association of Wales, and the Irish Football Association. FIFA, the international football body, was formed in Paris in 1904 and declared that they would adhere to the Laws of the Game of the Football Association. The growing popularity of the international game led to the admittance of FIFA representatives to the IFAB in 1913. The board consists of four representatives from FIFA and one representative from each of the four British associations.

Football is played at a professional level all over the world. Millions of people regularly go to football stadiums to follow their favourite teams, while billions more watch the game on television or on the internet. A very large number of people also play football at an amateur level. According to a survey conducted by FIFA published in 2001, over 240 million people from more than 200 countries regularly play football. Football has the highest global television audience in sport.

In many parts of the world, football evokes great passions and plays an important role in the life of individual fans, local communities, and even nations. Ryszard Kapuściński says that Europeans who are polite, modest, or humble fall easily into rage when playing or watching football games. The Ivory Coast national football team helped secure a truce to the nation's civil war in 2006 and it helped further reduce tensions between government and rebel forces in 2007 by playing a match in the rebel capital of Bouaké, an occasion that brought both armies together peacefully for the first time. By contrast, football is widely considered to have been the final proximate cause for the Football War in June 1969 between El Salvador and Honduras. The sport also exacerbated tensions at the beginning of the Croatian War of Independence of the 1990s, when a match between Dinamo Zagreb and Red Star Belgrade degenerated into rioting in May 1990.

Women's association football

Early women's football

Women may have been playing "football" for as long as the game has existed. Evidence shows that an ancient version of the game ( Tsu Chu) was played by women during the Han dynasty (25–220 CE). Two female figures are depicted in Han dynasty (25–220 CE) frescoes, playing Tsu Chu. There are, however, a number of opinions about the accuracy of dates, the earliest estimates at 5000 BCE.

Association football, the modern game, also has documented early involvement of women. An annual competition in Mid-Lothian, Scotland during the 1790s is reported, too. In 1863, football governing bodies introduced standardised rules to prohibit violence on the pitch, making it more socially acceptable for women to play. The first match recorded by the Scottish Football Association took place in 1892 in Glasgow. In England, the first recorded game of football between women took place in 1895.

The best-documented early European team was founded by activist Nettie Honeyball in England in 1894. It was named the British Ladies' Football Club. Nettie Honeyball is quoted as, "I founded the association late last year 894 with the fixed resolve of proving to the world that women are not the 'ornamental and useless' creatures men have pictured. I must confess, my convictions on all matters where the sexes are so widely divided are all on the side of emancipation, and I look forward to the time when ladies may sit in Parliament and have a voice in the direction of affairs, especially those which concern them most." Honeyball and those like her paved the way for women's football. However, the women's game was frowned upon by the British football associations and continued without their support. It has been suggested that this was motivated by a perceived threat to the 'masculinity' of the game.

Women's football became popular on a large scale at the time of the First World War, when employment in heavy industry spurred the growth of the game, much as it had done for men 50 years earlier. The most successful team of the era was Dick, Kerr Ladies F.C. of Preston, England. The team played in the first women's international matches in 1920, against a team from Paris, France, in April, and also made up most of the England team against a Scottish Ladies XI in 1920, and winning 22–0.

Despite being more popular than some men's football events (one match saw a 53,000 strong crowd), women's football in England suffered a blow in 1921 when The Football Association outlawed the playing of the game on Association members' pitches, on the grounds that the game (as played by women) was distasteful. Some speculated that this may have also been due to envy of the large crowds that women's matches attracted. This led to the formation of the English Ladies Football Association and play moved to rugby grounds.

Association football has been played by women since at least the time of the first recorded women's games in the late 19th century. It has traditionally been associated with charity games and physical exercise, particularly in the United Kingdom. In the late 1960s and early 1970s, women's association football was organised in the United Kingdom, eventually becoming the most prominent team sport for British women.

20th and 21st century

The growth in women's football has seen major competitions being launched at both national and international level mirroring the male competitions. Women's football has faced many struggles. It had a "golden age" in the United Kingdom in the early 1920s when crowds reached 50,000 at some matches; this was stopped on 5 December 1921 when England's Football Association voted to ban the game from grounds used by its member clubs. The FA's ban was rescinded in December 1969 with UEFA voting to officially recognise women's football in 1971.

The FIFA Women's World Cup was inaugurated in 1991 and has been held every four years since, while women's football has been an Olympic event since 1996.

Gameplay

Association football is played in accordance with a set of rules known as the Laws of the Game. The game is played using a spherical ball of circumference, known as the '' football'' (or ''soccer ball''). Two teams of eleven players each compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw. Each team is led by a captain who has only one official responsibility as mandated by the Laws of the Game: to represent their team in the coin toss before kick-off or penalty kicks.

The primary law is that players other than goalkeepers may not deliberately handle the ball with their hands or arms during play, though they must use both their hands during a throw-in restart. Although players usually use their feet to move the ball around they may use any part of their body (notably, "heading" with the forehead) other than their hands or arms. Within normal play, all players are free to play the ball in any direction and move throughout the pitch, though players may not pass to teammates who are in an offside position.

During gameplay, players attempt to create goal-scoring opportunities through individual control of the ball, such as by dribbling, passing the ball to a teammate, and by taking shots at the goal, which is guarded by the opposing goalkeeper. Opposing players may try to regain control of the ball by intercepting a pass or through tackling the opponent in possession of the ball; however, physical contact between opponents is restricted. Football is generally a free-flowing game, with play stopping only when the ball has left the field of play or when play is stopped by the referee for an infringement of the rules. After a stoppage, play recommences with a specified restart.

At a professional level, most matches produce only a few goals. For example, the 2005–06 season of the English Premier League produced an average of 2.48 goals per match. The Laws of the Game do not specify any player positions other than goalkeeper, but a number of specialised roles have evolved. Broadly, these include three main categories: strikers, or forwards, whose main task is to score goals; defenders, who specialise in preventing their opponents from scoring; and midfielders, who dispossess the opposition and keep possession of the ball to pass it to the forwards on their team. Players in these positions are referred to as outfield players, to distinguish them from the goalkeeper.

These positions are further subdivided according to the area of the field in which the player spends the most time. For example, there are central defenders and left and right midfielders. The ten outfield players may be arranged in any combination. The number of players in each position determines the style of the team's play; more forwards and fewer defenders creates a more aggressive and offensive-minded game, while the reverse creates a slower, more defensive style of play. While players typically spend most of the game in a specific position, there are few restrictions on player movement, and players can switch positions at any time. The layout of a team's players is known as a ''formation''. Defining the team's formation and tactics is usually the prerogative of the team's manager.

Laws

There are 17 laws in the official Laws of the Game, each containing a collection of stipulation and guidelines. The same laws are designed to apply to all levels of football, although certain modifications for groups such as juniors, seniors, women and people with physical disabilities are permitted. The laws are often framed in broad terms, which allow flexibility in their application depending on the nature of the game. The Laws of the Game are published by FIFA, but are maintained by the IFAB. In addition to the seventeen laws, numerous IFAB decisions and other directives contribute to the regulation of association football. Within the United States, Major League Soccer used a distinct ruleset during the 1990s and the National Federation of State High School Associations and National Collegiate Athletic Association still use rulesets that are comparable to, but different from, the IFAB Laws.

Players, equipment, and officials

Each team consists of a maximum of eleven players (excluding substitutes), one of whom must be the goalkeeper. Competition rules may state a minimum number of players required to constitute a team, which is usually seven. Goalkeepers are the only players allowed to play the ball with their hands or arms, provided they do so within the penalty area in front of their own goal. Though there are a variety of positions in which the outfield (non-goalkeeper) players are strategically placed by a coach, these positions are not defined or required by the Laws.

The basic equipment or ''kit'' players are required to wear includes a shirt, shorts, socks, footwear and adequate shin guards. An athletic supporter and protective cup is highly recommended for male players by medical experts and professionals. Headgear is not a required piece of basic equipment, but players today may choose to wear it to protect themselves from head injury. Players are forbidden to wear or use anything that is dangerous to themselves or another player, such as jewellery or watches. The goalkeeper must wear clothing that is easily distinguishable from that worn by the other players and the match officials.

A number of players may be replaced by substitutes during the course of the game. The maximum number of substitutions permitted in most competitive international and domestic league games is three in ninety minutes with each team being allowed one more if the game should go into extra-time, though the permitted number may vary in other competitions or in friendly matches. Common reasons for a substitution include injury, tiredness, ineffectiveness, a tactical switch, or timewasting at the end of a finely poised game. In standard adult matches, a player who has been substituted may not take further part in a match. IFAB recommends "that a match should not continue if there are fewer than seven players in either team". Any decision regarding points awarded for abandoned games is left to the individual football associations.

A game is officiated by a referee, who has "full authority to enforce the Laws of the Game in connection with the match to which he has been appointed" (Law 5), and whose decisions are final. The referee is assisted by two assistant referees. In many high-level games there is also a fourth official who assists the referee and may replace another official should the need arise.

Goal line technology is used to measure if the whole ball has crossed the goal-line thereby determining whether a goal has been scored or not; this was brought in to prevent controversy. Video assistant referees (VAR) have also been increasingly introduced in high-level matches to assist officials through video replays to correct clear and obvious mistakes. There are four types of calls that can be reviewed: mistaken identity in awarding a red or yellow card, goals and whether there was a violation during the buildup, direct red card decisions, and penalty decisions.

Ball

The ball is spherical with a circumference of between , a weight in the range of , and a pressure between at sea level. In the past the ball was made up of leather panels sewn together, with a latex bladder for pressurisation but modern balls at all levels of the game are now synthetic.

Pitch

As the Laws were formulated in England, and were initially administered solely by the four British football associations within IFAB, the standard dimensions of a football pitch were originally expressed in imperial units. The Laws now express dimensions with approximate metric equivalents (followed by traditional units in brackets), though use of imperial units remains popular in English-speaking countries with a relatively recent history of metrication (or only partial metrication), such as Britain.

The length of the pitch, or field, for international adult matches is in the range of and the width is in the range of . Fields for non-international matches may be length and in width, provided that the pitch does not become square. In 2008, the IFAB initially approved a fixed size of long and wide as a standard pitch dimension for international matches; however, this decision was later put on hold and was never actually implemented.

The longer boundary lines are ''touchlines'', while the shorter boundaries (on which the goals are placed) are ''goal lines''. A rectangular goal is positioned on each goal line, midway between the two touchlines. The inner edges of the vertical goal posts must be apart, and the lower edge of the horizontal crossbar supported by the goal posts must be above the ground. Nets are usually placed behind the goal, but are not required by the Laws.

In front of the goal is the penalty area. This area is marked by the goal line, two lines starting on the goal line from the goalposts and extending into the pitch perpendicular to the goal line, and a line joining them. This area has a number of functions, the most prominent being to mark where the goalkeeper may handle the ball and where a penalty foul by a member of the defending team becomes punishable by a penalty kick. Other markings define the position of the ball or players at kick-offs, goal kicks, penalty kicks and corner kicks.

Duration and tie-breaking methods

90-minute ordinary time

A standard adult football match consists of two halves of 45 minutes each. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time. The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called ''additional time'' in FIFA documents, but is most commonly referred to as ''stoppage time'' or ''injury time'', while ''lost time'' can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. Stoppage time does not fully compensate for the time in which the ball is out of play, and a 90-minute game typically involves about an hour of "effective playing time". The referee alone signals the end of the match. In matches where a fourth official is appointed, towards the end of the half, the referee signals how many minutes of stoppage time they intend to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee. Added time was introduced because of an incident which happened in 1891 during a match between Stoke and Aston Villa. Trailing 1–0 with two minutes remaining, Stoke were awarded a penalty kick. Villa's goalkeeper deliberately kicked the ball out of play; by the time it was recovered, the clock had run out and the game was over, leaving Stoke unable to attempt the penalty. The same law also states that the duration of either half is extended until the penalty kick to be taken or retaken is completed; thus, no game can end with an un-completed penalty.
