IMO 4-3-1-2 or 4-1-2-1-2 more precisely, at certain area when defending and attacking will transform into 2-1-4-1-2 when attacking, and 4-1-3-2 when defending. When defending, the Mezzalas are covering flanks area and center of midfield (depends on opponent movement with the ball), so the Trequartista should drop to center of midfield to help the Mezzalas. And also the strikers should drop quite deeper, and pressing the opponent. The Strikers should be fast, good dribbler and finisher, and it would be perfect if both of them are good headers, because the fullbacks (main crosser provider) mostly will make deep crossing.
- I prefer more defensive DMC, rather than deep lying playmaker. All the creativity are taken by the Trequartisa and one of the Mezzala.
- The Mezzalas are combination of attacking B2B midfielder (technical) and defensive B2B midfielder (physical). And the play on the side that fit with their preferred foot, because they have some duty to provide crossing.
My 4-3-1-2 Dream Team Lineups.
