The word center, which is rarely mentioned, is easy to cause ambiguity, which can include the position of the whole midfield or the middle position of the third midfield.
If it is a diamond midfield, it is divided into: front waist, left avant-garde, right avant-garde, and back waist (there may be 2 back waist); If it is a parallel midfield, it is divided into: left avant-garde, right avant-garde and organizational avant-garde (middle avant-garde).
The front waist, usually a player with good passing and ball control skills, is the core of the attack and is specially used to transport shells for the striker. The defensive center of the back is the hub connecting the midfield and the defender in the attack. The defense is the barrier before the defense, which is usually borne by the players with strong interception ability. Some teams' back pass control technology is also outstanding, with special emphasis on long pass technology. In the team playing parallel midfield, the middle and avant-garde technique is usually the best, and the passing and control belt will be more prominent in the team and the vision will be broad. It plays a connecting role, equivalent to the role of the brain.
