I am facing a similar formation in CL. Instead of AM, there is an ST. So it's 3DC-2MC-2W-3ST
I have found that someone beat him 4-2 with a butterfly.
Not a proven counter yet. I played Champions League Semi-Final against that formation with Butterfly, opponent +1 Level, +11%Q. Lost 1-3 at home, won 2-0 away. Go figure...
Any formation or tactics advice given is based purely on experience with my teams...
