Football, with the reputation of "the first sport in the world", is the most influential single sport in the world. In a standard football match, the two teams each send 10 players and 1 goalkeeper, * * *1/people to fight and attack on a rectangular grass court. The purpose of the game is to shoot the football into the opponent's goal as much as possible, and you can get one point for each goal. When the game is over, the team with the most points wins. If the score is the same within the specified time, it depends on the rules of the game. You can draw lots, play overtime or shoot each other (12 step) and so on. In the football match, except the goalkeeper can touch the ball with his hand in his own restricted area, each player can only control the football with other parts of his body except his hand (except the foul ball).
