How to Win Against Any Formation?

[CIBlue]

I'm facing a tough opponent with a really wierd formation: 3-2-1-2-2.
----ST---ST----
AML--------AMR
-------MC-------
--DMC---DMC--
DL----DC----DR
-------GK-------
I thought about countering it as if he's a 5-3-2, but unsure about it. How should I proceed.

I would consider it a 3-5-2, but those DMCs might have blue arrows on them. Based purely on the formation alone, I would go for 3-2-2-2-1:

--------ST-------
AML----------AMR
----MC----MC----
DML----------DMR
----DC-DC-DC----

You'll attack down the wings, red arrows on the wingers. Whether you play attacking or counter attacking depends on which team is stronger.
