Is there a requirement for the specific position of the football set piece defense?

The foot bush leak position is generally not fixed. Sometimes behind the center forward, sometimes back to the midfield, sometimes on both sides, but it is certain that the striker is the second line of attack, and generally speaking, there are only two standing techniques in football besides the goalkeeper, attacking and defending, the offensive position is to avoid the opponent as much as possible, and the defensive position is to try to get as close as possible to the opponent who may get the right to the ball.

Tactics of football positioning

All tactics are based on the distribution of players on the field combined with positioning, and then can be more convenient to use their skills in various combinations, static modern football.

The core of the various position formations comes from the WM and 442 bit systems, and the 442 system itself is also an evolved version of the former.

The midfield retreat of the basic formation is the 532 system, which is characterized by the fact that the up and down amplitude of the two fullbacks will be greater, and the same defender strengthens the midfield in advance is the 352 formation, the basic purpose is to compete for the control of the midfield, the basic formation midfield is one in advance, that is, 433, the striker ** one to the midfield is 451, the striker ** one, and then the midfielder ** one person, it becomes 541.

A real game, the beginning of the occupation is only a basic division of the area of responsibility, the actual game is rarely fixed formation, are converted in several standing systems, poor Zheng and basic position, often used to train players of the special position technology is more useful, each position in the game technology and requirements have a certain commonality.

High post defense: That is, the defender is far away from all other positions on the blue board, and generally defends more near the three-point circle. In the NBA, Qingzhao's high-post orange defense leaders are: Christton, Allen Iverson, etc.

Low post defense is the opposite of the high post, where the defender is close to the blue board. The best low-post defenders in the NBA are: Mo Ning, Yao Ming, etc.

In football, set-pieces that can be scored directly into the opponent's goal include free kicks, penalty kicks, and corner kicks. 1. There are two types of free kicks: direct free kicks (the kicking team can shoot the ball directly into the fouling team's goal to score) and indirect free kicks (the kicking team players are not allowed to score directly at the goal, and the ball must be kicked or touched by other team members before entering the goal).

FIFA's latest rules are that a foam spray is used to delineate the position of the ball and the position of the human wall after a free kick is awarded, and the free kick is delivered by touching the ball with your hands and then kicking the ball after the referee's whistle. 2. Penalty kicks. When a team is awarded a free kick in their own penalty area for violating one of the ten fouls that can be awarded as a direct free kick in the middle of the match, the penalty kick shall be taken.

Penalty kicks can be scored directly. At the end of each half of the game or the second half of the tiebreaker, an extended period of time shall be allowed to complete the execution of penalty kicks. 3. Corner kicks.

A method of restarting the game after a dead ball in soccer is a type of set-piece. A corner kick is awarded when the ball crosses the goal line in its entirety, whether on the ground or in the air, and the last person to touch the ball is a member of the defending team and is not a goal scored according to the winning rules. A corner kick can be scored directly into the opponent's goal.

Extended Information: Free kicks taken by players other than the goalkeeper If after the game has been played, the kicker touches the ball again carefully (except with his hands) before another player touches the ball: an indirect free kick is taken by the opponent at the place where the foul occurred. If, after the game has been played, the kicker deliberately touches the ball with his hand before the other players touch the ball:

A direct free kick is taken by the opponent at the place where the foul occurred; If the foul is committed in the kicker's own penalty area, a penalty will be awarded. Free kick by goalkeeper If after the game has been played, the goalkeeper touches the ball again before another player touches the ball (except with his hands): an indirect free kick is taken by the opponent at the place where the foul occurred.

Direct free kicks, corners, goal kicks and penalties.

The legal defensive position in basketball is the oft-heard vertical cylinder rule for defenders. On the pitch, the players have rights to the space directly above them. This principle protects the space above the players.

However, if a team player leaves a vertical position and makes physical contact, the player should be responsible and may be awarded a foul.

Defenders cannot put their arms above the attacking players to organize the offensive players to jump vertically and shoot; An offensive player cannot jump diagonally and crash into a defender who is in a legal position. If there is no physical contact, it is legal, if physical contact occurs, it is a foul and the player who lost his vertical position is responsible.

First question: the goalkeeper can move in advance.

The second problem: the ball can be placed arbitrarily in the corner area.

Hope it helps.
