4-4-2, most likely. If we take the most recent game:
GK: Sweeper Keeper
FBs: FB - Attack
CBs: CB - Defend
CMr: BWM - Defend
CMl: DLP - Support
LM: Winger - Attack
RM: Defensive Winger - Attack (tweak it a lot so that he comes inside to act as a support striker)
STr: DLP - Attack/Playact
STl: Complete Forward - Attack
Something like that anyway.
