He has a gaping hole right up the middle so your plan of attack should be obvious. Why would you even think of attacking his flanks? Go up the middle and his DL/DR are effectively useless.
At minimum you want a central DC and a DMC to cover his central attackers. 2 MCs along with the DMC will give you numerical advantage and thus possession advantage at midfield.
That leaves you with 4 players to place, and at least 2 of them must be defenders and at least 2 (maybe the same 2) must be on the flanks. Look at his past games to get a handle on his AML & AMR (and check his MCs as well) but you can probably bet he's playing hard attacking with red arrows on the AMs. If you've got solid defenders, you can get by with 3 DCs and use your remaining two slots at MR/ML with blue arrows to help cover his flankers, or use DML/DMR if you've got them.
