When playing the 4-3-2-1 soccer formation, you can divide the defenders into 2 center-backs and 2 fullbacks- one on either side. Of the 3 midfielders, the central player is defense-oriented while the other 2 are assigned offensive roles. The 2 attacking midfielders focus on the middle (not the wings) and need to track back to support the defense.
