The front waist is slightly forward. Avant-garde is more organized in midfield and also a defensive barrier in front of the back line. According to the specific division of labor, some avant-garde are connected in series in the center and backcourt, some adjust the offensive rhythm through passing and controlling, and some impact the opposing defense line on the side and cross the winger. The front waist is more behind the striker, launching an attack, transporting shells forward, and having higher requirements for dribbling, holding the ball at the front of the opponent's restricted area, breaking through in time and organizing a second attack. A good front waist should also know how to sort out the attack vein, preferably a long shot, and the opponent will attack the door when shrinking the defense. However, there is no absolute difference. A good midfielder is versatile. In actual combat, it depends on who is more suitable for which position. However, generally speaking, a midfielder can win the Jianghu with a stunt. After all, all-rounder like Zidane is rare.
