Soccer, is a sport played between two teams of eleven players with a spherical ball. At the turn of the 21st century, the game was played by over 250 million players in over 200 countries, making it the world's most popular sport. The game is played on a rectangular field of grass, with a goal in the middle of each of the short ends. The object of the game is to score by driving the ball into the opposing goal.In a game, the goalkeepers are the only players allowed to touch the ball with their hands or arms, while the field players typically use their feet to kick the ball into position, occasionally using their torso or head to intercept a ball in midair. The team that scores the most goals by the end of the match wins. If the score is tied at the end of the game, either a draw is declared or the game goes into extra time or a penalty shootout, depending on the format of the competition. The Laws of The Game were originally codified in England by the Football association in 1863 and have evolved since then. Association football is governed internationally byFIFA, which organises the FIFA worldcup every four years.
Players and equipments
Each team consists of a maximum of eleven players, 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 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. 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, 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 "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", 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. 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, though popular use tends to continue to use traditional units in English-speaking countries with a relatively recent history of metrication, such as Britain. The length of the pitch for international adult matches is in the range of 100–110 m and the width is in the range of 64–75 m. Fields for...
