I met this tactic this season. I have some solutions for you: 4-3n-3, 4-4-2 classic, 4-3n-1-2, 4-1-2-1-2 Narrow Diamond, 3-5-2 flat, 3n-1-4-1. With all this tactics, you always have more possesion, more shots and exploit his lone DC and destroy his midfielders with lone MC. 4 good form defenders(and DMC support in some tactics) or 3n defender and ML/MR are enough against ML/MR and 2 ST. Good luck!
