I just beat a guy with that formation playing away. Played my usual 413N2 normal counter attack. Won 0-3 away. My two defensive minded MC on his CM and my attack minded MC in the mid. I had my DMC with blue arrow back.

Thing is with one upfront, he doesn't get many chances so counter attack is safer to use.

I guess you can go 41212 instead. I think 4132 is more solid than 41212. Your MC do his bit to win the midfield battle and if he gets the ball would get a free run like if you played 41212. I can never see why to play an AMC is better than a MC mid... well unless you play both.
