The player in question has same player quality as mine (19.1 vs 18.9), and here's the formation

----ST--ST----
AML--------AMR
----MC-MC-MC---
-----------------
DL----DC-----DR

I'm pretty sure the DC has a down arrow.

I checked out Adel Gama's thread and only "3-3-2-2" info I found was that it can be used to counter forms with weak flanks

I'm thinking of doing this

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

is that a good idea? if not, what form(s) would better give me an edge in the match?
