How to beat strange 3-1-2-2-2?

Hey guys, I've got a match tommorow against a fairly odd formation. It's a bit strange but it seems to be working for him as hes in seconds place in the league, 2 points behind me so i really want to win to make my lead bigger
Overall my team is 2 points better (54.4 vs 52.2) than his but im playing away.

---DC-DC-DC---
------DMC-----
MR-------MC---
------AMC---AML
----ST---ST----

Any suggestions?

Thanks in advance

4-5-1v or 4-1-3w-2. Attack the flanks.

4-1-3W-2 worked just fine. Had about 60% possesion and won 1:0

Good work
