I created my own tactic very similar to this ever since the beta came out. I was heavily inspired by Cruijff's 3-4-3 diamond tactic. On paper, my formation is 4-2-3-1 with DM-CM-AM but turns into 3-1-6/3-4-3 on the pitch with one of the fullback act as inverted wing back, DM SV on attack, CM Mez on support, AM AttMid on attack.
