Should have played 3N-1-2W-2-2 or 3N-1-2W-1-3 or even 3N-3W-1-2. He had no wingers so 4 at back was useless. 3 ST so 3 DCs and 1 DMC to support them and even take on attacking MCs. AnAMC to take on his DMC and not to allow him to help the DCs to take on STs. He had 4 at back so as I say, leave the DL/DR jobless and put all pressure of the AMC(s) and STs on the 2 DCs. So the DCs would eventually fail under pressure and let ur ST score. Since the AMC will keep the DMC in check, so the DMC would have not been able to help the DCs even with blue arrows.
This would have really worked, I am confident. With attacking, mixes passing, short passing, no counter or offside, hard tackling.
Try it if u get a chance again and post the results.
