A football match, two teams participate in a game, and each team has no more than 1 1, including a goalkeeper. Any team with less than 7 players can't start the game.
In official competitions sponsored by FIFA, the Intercontinental Federation or the National Association, a maximum of 3 substitutes can be used in each competition. The rules of the competition should specify how many substitutes can be nominated, from 3 to no more than 7. Any nominated substitute must play before kick-off or after the start of the game.
Extended data:
In the standard 1 1 football match, the two teams each sent 10 players and 1 goalkeepers, a total of 22 people, to fight, defend and attack on the rectangular grass court.
Try to shoot the football into the opponent's goal in the game, and you can get one point for each goal. When the game is over, the team with more 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 exchange penalties (12 yards) 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).
