In order to meet the needs of offensive and defensive tactics, players' positions on the field are enumerated and their responsibilities are divided, which is called competitive formation. The name of the formation is determined by the shapes listed by the player. Since the middle of19th century, there has been the first football competition formation in the world. Today's "433", "352" and "424", as well as the "cement" and "chain" adopted by some countries, have all evolved and grown up along this unsightly discipline, which refers to the enumeration of players' positions on the field or the general tactical organization form. Football behavior has developed to the present, and there are many formations. Every player must appreciate it and throw his palm into the formation. The details are as follows: (1) L+9 and 2+2+6 formations, which occurred in1) L+were the original formations of football matches in the 1960s and 1970s. Its basic tactical idea is one-sided pursuit of attack, and "kicking" and catching the ball are the characteristics of the game scene. So as far as formation is concerned, organizing players is of little significance. (2) The formation of 2+3+5 is accompanied by the growth of passing in the evolution of football, and the organization of players on the field becomes more and more important, so the formation of 1+2-3+5 appears. In this formation, the first instinctive function of the central avant-garde is to attack, and the two marginal avant-garde intervene in defense, first of all, to defend the other two fronts. This sudden basic ideological attack is still dominant, starting from the form of local transmission, and gradually forming and growing into this formation. (3) 3+2+2+3 (W-M) formation W-M formation was created by Chapman, head coach of British ordnance field team, after changing offside rules in 1925. The basic idea of this formation is to try to break the opponent's attack through a smooth defensive process. First of all, the principle is "peace first". Because what came out this time was a good end. Therefore, it was not only quickly taken over by Britain, but also spread to Europe and even the world. The main feature of this formation is the endless transition between area and man-to-man Loose when close to the target, loose when far away from the target. When instigating the attack, stay in the center and defend on both sides. Its offensive feature is that two inside forwards retreat. As the key organizers of the attack, center and double forwards shoulder the primary mission of scoring goals. Although this formation is based on the idea of strengthening defense, it actually prevents the offside track from increasing the number of goals after the change of formation. However, because the number of defenders is too small when attacking and the defensive rules when opponents instigate fast breaks are too weak, especially in the early 1930s, Hungary adopted a four-striker system, so in 1958, Brazil created another formation with 1+4+2+4 formation. (4) 4+2+4 formation This formation is an extremely balanced formation enumerated by offensive and defensive players. In the use of this formation, the two avantgarde are the backbone of the past and the future. When they attack, they actively organize to meet, and when they are punctual, they quickly cut off the burden. Because of frequent activities, this formation has extraordinary requirements for the physical strength and technological completeness of the two avantgarde. The weakness of this formation is that the midfield strength is relatively weak. This is especially true when two avant-garde players are short of physical strength and comprehensive skills. This outbreak mode also requires the front line and the defense line to actively respond to the midfield attack and defense at different stages of attack and defense. The difference between it and 1+4+2+4 formation is that a pioneer retreats to the midfield to enhance the strength of the midfield. The position of this formation is more agile, which requires the players to take the overall position according to the battle situation, and at the same time, always connect the overall organization during the change of position. Judging from the defenders, 1+4+3+3 formation has at least 7 defenders. Generally speaking, most teams usually have six people to take the initiative to attack. When attacking, the three forwards and the three avant-garde are always closely defended, so the 1+4+3+3 formation emphasizes the sudden insertion of the back line. When the defender inserts, this formation requires the inserter to seize the opportunity and act steadily, on the other hand, it requires other players to pay attention to make up the position when the opponent returns fire. When the attacking defender intervened in assists several times, the defender also asked the pioneer of his team to retreat and intervene in defense. (5) 4+4+2 formation This formation was confirmed in the 1966 World Cup. At that time, due to the lack of world-class excellent wingers, British coach Ramsey pulled back a winger and formed a formation of 1+4+4+2. The offensive feature of this formation is that midfielders and defenders frequently engage in sideline activities, which creates a dangerous situation in front of the opponent's door. Another common attack style is that two inner ladas create width, and two inner feet in midfield surround the penalty area to score points. The third common way of attack is two forwards with fast operation speed and good skills, who pass quickly and long, and then counter-attack quickly after steals the ball. In terms of garrison, this formation mainly emphasizes the return of players and the organization and coordination under intensive garrison. (6) 3+3+4 formation This formation is the most popular in Central and North America, and it is also adopted in Europe and South America. It is characterized by its emphasis on the number advantage of attack and its tendency to take risks and move. When attacking, in addition to four forwards and three avant-garde, two defenders also actively assisted. When guarding the time, the 1+3+3+4 formation requires that one player in the midfield must retreat as a man-to-man central defender, and the striker will retreat to enhance the strength of the midfield. Most central defenders give defensive instructions in the form of scavengers, ready to make up positions at any time. This formation is characterized by strong attack, but the defensive organization is prone to cracks if it is slightly negligent, especially when the sideline players are pressed around the restricted area, and the other side suddenly instigates a long pass to quickly counterattack, which makes it easier to expose the short board. (7) "Concrete" Formation The "concrete" formation was formed when the Italian team crashed in 1949 and disappeared to 65438+. This formation is a complete enumeration of defensive positions. The sweeper is responsible for the key organization and instruction of defense. He was placed behind all the defenders except the goalkeeper. If any area is broken by an opponent, sweeping the floor will make up the challenge. If no one is watching the attacker, the sweeper will cut it off. When the sweeper leaves his position and goes to war, there must be other defenders to fill the sweeper's position. The guiding ideology of this formation is to establish loyal garrison, but its transformation forms are various, sometimes the attackers can be listed as 3 ~ 4 people, and sometimes only 1-2 people. When confronting 1+4+2+4 formation, the "concrete" formation often confronts 1+L+4+2+3 or 1+L+4+3+2, while the opponent adopts 1+4+3+3 formation. In a word, the "concrete" formation always has at least one more player than the opponent in the guarding city, regardless of the structure of the opponent.
