A standard football match consists of eleven players from each team, including ten players and a goalkeeper. They fight and attack each other on a rectangular grass court.
Eleven-player system, there are eleven players on each side of the football match, including a goalkeeper, three to five defenders, two to five midfielders and one to three forwards. In large-scale competitions, there will be several (five to eight) substitutes on both sides, and a formal competition can replace up to three players. From 20 16, the game enters overtime and another substitution quota is obtained.
There is no limit to the number of substitutes for friendly matches. Players who replace the next game can't go back to the court to play.
Except the goalkeeper can touch the ball with his hand in his own restricted area, other players can only touch the ball with their body parts other than their hands (except foul balls). The purpose of the game is to shoot the ball into the opponent's goal as much as possible, and score one point for each goal. When the game is over, the team with the most points will represent the winner.
The duration of the game is two equal-length half-courts, 45 minutes each * * * 90 minutes. If the score is the same within the specified time, it depends on the rules of the game. You can draw lots, play overtime (30-minute overtime) or shoot the opponent's penalty. If it's a league, it's a draw.
Field position
Goalkeeper: The main duty is to hold the goal, observe the changes of the game on the field, and organize and direct the attack and defense of the whole team.
Full-back: other players who are mainly responsible for defending the opposing winger or inserting the winger position, cooperate with the central defender to make up for the opposing position and block the road to attack the goal directly. When our team attacks, we can also wait for opportunities to help out and play the role of winger.
Central defender: it is the pillar of defense. Its main responsibility is to defend the most dangerous area in front of the goal center, stop the opponent from shooting, and cooperate with the full-back and another central defender to make up for the opponent's position. It should also play the role of offensive and defensive organization and command.
Avant-garde: active in the middle zone between striker and defender, its main responsibility is to control the midfield, which is the barrier of defense and the link of frontier attack. It is the core role of the team to attack, retreat and defend, punctuate or shoot long distances at the right time.
Center: The main duty is to shoot through or catch the ball. Secondly, it is our team's "sharp knife" and "shooter" to disturb the opponent's defense line and create opportunities for our companions to insert, cut or shoot through cross transposition and left-right cooperation. Punctuality is the first line of defense for the whole team.
Winger: The main responsibility is to break through the opponent's defense line from the side, take the ball into the shot or cross the baseline or outflank the shot. Keep an eye on our full-backs when defending, prevent them from assisting freely, and help our full-backs defend the opposing wingers.
