I faced something similar like this before but my opponent's defence was 3 DC. I choose 4-5-1 V style. Play Normal, focus passing down both flank, pressing own-half, mixed passing style, counter attack and red arrow DL, DR, AMR, AML.

In your sittuation, I think you should try 4-1-4 (2 MC, ML, MR)-1 with normal playing, down both flank, mixed style, pressing own-half, counter attack and red arrow 4 player in both flanks
