Common formations in soccer are as follows:
1.4-4-2 formation: This is a traditional formation that includes 4 defenders, 4 midfielders and 2 forwards. The advantage is that there are many people in the midfield, which is conducive to controlling the pace of the game and blocking in the midfield, and having two strikers can form a strong attacking threat.
2.4-3-3 formation: This formation consists of 4 defenders, 3 midfielders and 3 forwards. The advantage is that there are more participants on the offensive end, which can form more offensive combinations and passing lines, increasing scoring opportunities.
3.3-5-2 formation: This is a more flexible formation that includes 3 defenders, 5 midfielders and 2 forwards. The advantage is that it can form a relatively compact midfield control when defending, and at the same time, it can form multiple passing lines through the numerical advantage of the midfield when attacking.
4.4-2-3-1 formation: This formation consists of 4 defenders, 2 midfielders, 3 forward midfielders and 1 striker. The advantage is that the midfield position is well set up, which can create solid midfield control while maintaining an attacking threat.
Each formation has its advantages and disadvantages, depending on the team's tactical set-up, player style and opponent's characteristics, choosing the right formation can better play the team's strength and tactical characteristics.
