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.
