Association football, commonly known as football or soccer, is a team sport  played between two teams of 11 players each. It is widely considered to be the most popular sport in the world Football is a ball game played on a rectangular grass or  artificial turf  field, with a goal at each of the short ends. The object of the game is to score by manoeuvring the ball into the opposing goal. In general play, the goalkeeper  is the only player allowed to use their hands or arms to propel the ball; the rest of the team usually use their feet to kick  the ball into position, while they may also occasionally use their torso or head to intercept a ball in mid air. 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 and/or a penalty shootout  depending on the format of the competition.
