Against 3-0-4-1-2 (3-5-2)

So lets talk about the next (this) scheme :)
DL----DC----DR
---------------
ML--MC-MC--MR
------AMC------
-----ST-ST-----
Today Ive just beat it with 4-5-1 V formation on CA with 0:2.
Ive got the superior team but somehow couldnt get enough possesion at the begining and switched to CA.
I know that i won but Im not sure that this is the optimal counter (tomorrow Im playing again against this scheme). And im tghinking that 4-1-2-1-2 narrow diamond will be better (again with CA, cuz he got more plrs in the middle).

I think the narrow diamond will be good. Not sure where he attacks, so that formation will give you adequate cover on all sides. When you attack, you have an AMC in the hole while he has no DMC, and you have two ST against his one DC. Attack through the middle, but try to have better MCs than him.

Used narrow diamond without even watching the match and won 0-3. So (today) narrow diamon (4-1-2-1-2) and V-formation (yesterday) (4-1-2-2-1) gained me a victory over this formation.
