How to Beat 3-4-3? DL and 2 DCs. Q

Looking for counter formation/tactics to this:


ST-ST-ST

ML-MC- MC-MR

DL- DC-DC


Might 4-1-3(n)-2 or 4-4-2 work?

I weren't sure about typing this formation correctly, so I visualised it. Match is in 21hrs, looking for answer ASAP. This match basically decides the league winner.

Thanks in advance.

4-4-2, attack down the left flank. This will put press on his single player on his right flank.
