I agree 3w-1-4-2 to start if you want to be aggressive from the off!, if you want to be a bit more cautious then 4-1-3w-2!, you need red arrows on all midfield( DMC included) and strikers!, play attacking, mixed or down flanks focus passing! (switch round if its not working)
Hard attacking, close down own half, mixed passing, zonal marking, dont force counter attacks!. If you nick a goal playing 3-1-4-2 and want to closer up shop then take off a MC and put on a DC to go to 4-1-3w-2 or take off a striker and put on a DC and go to 4-1-4-1!.
