Association football

Association football, commonly also referred to as soccer, is the most popular version of the football sport. In association football two teams, consisting of 11 players each, play against each other on a square-shaped grass field with a football (which the game is named after). Each team must cooperate with their team players to get the football into the opposite team's goal as many times as possible.

Only one player from each team, called the Goalkeeper, can touch the football with his hands and arms. The rest of the team members, categorized as either defenders, midfielders or attackers, are only allowed to move the ball by the use of their feet, chests and heads.

If the teams have an even amount of goals by the time of the match's end, the game will move on to either extended time, or even penalty shoot-out, until a winner can finally be declared.
