How can I win against 3n-2w-3w-1-1 formation?

[DrJack]

Hey everybody

I need help. A guy in our league has choosen a strange formation and since then, he is winning all matches and nobody seems to have a good tactic against him.
We have about the same team quality, but I don't know which formation I should choose.

His formation:

------ST------
-----AMC------
ML---MC---MR
DML-------DMR
--DC-DC-DC---

Can you give me a good counter formation please?
