Well, I never have a match against that particular formation before. You ask for an idea. I give you my idea which is the formation I would prefer if I have the chance to face this formation personally.

The idea behind it is your opponent only have one player in the front, that is why 3 defenders is enough, DR-DC-DL. 1 DMC with up arrow to give an extra cover for the striker and also helps the midfielder to dominate the play. As for attacking I would use up arrow on my ML/MR with down both flanks setting because obviously the center area is too crowded with the 2 DMC. Because the opponent use 3 defenders, then using 2 forwards is the best option. Finally I would wraps everything up with mixed passing.
