How to Win Against Any Formation?

[July Fourth]

I need some help with this guys. It's the Cupfinal. I never have seen this kind of formation, so I'd appreciate it f anyone could help me out.
I was thinking playing a 3 (3x DC)-5-2 (V formation)

Try and get your balls down the left hand side of the field, he doesn't have much cover over there and it looks like his weak spot.

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

as odd as that looks above, it seems to be good for a few managers out there.

Focus - down left flank.
