Against 4-4-1-2 ?

[dv8r]

Against 4-4-1-1 you can use 3-5-2 V formation

That's...

-----ST----ST----
AML------------AMR
-----MC----MC---
-------DMC--------
-----DC-DC-DC----

You will need to focus down both flanks and mixed passing, normal tackling, zonal marking, pressing own half, force counter and no offside trap.

Mentality is up to you, but since you need to win, I recommend attacking mentality
