What tactic with 2 defensive midfielders playing?

[sofoot]

Hi all, I'm looking for a tactic with PSG and 4 defensive midfielders available in the squad : Fellaini, Matuidi, Sissoko & Thiago Motta. Something like 4-3-3 often used in the tactics I could see here but with midfielders lines switched (2 down & 1 up instead of 1 down & 2 up).

Thanks!
