Used this tactic just so I could keep the promises to a couple of giving some youngsters a shot. Had 2 CMs, 2 AMs & 1 Striker. Every one in the league just about only plays with one striker up top so a 4 man backline performs fine. I rather the three attackers stay relatively center in order to draw the opposition center halves out of position. The Mezzalas in theory are supposed to keep pressure off my deep lying playmaker.
My young striker has a finishing rating of 17.
