Any idea about this strange 3-2-2-2-1 formations? Does it work?

Personally, I think DMs are very important, but you only have the 3* one. I would recommend 4-5-1 V, attacking him down his right and your left, which are the same, with only blue arrows on the DMC, but that's what makes me think twice.

4-5-1 V is definitely my first choice, I've just need to be sure about that, so thank you for your advise. DM + DML + DMR are my next transfer priorities, I will buy them as soon as possible, but I must sell several players first and I'm also expecting youth players in few days. I needn't to play defensive so far this season, but no doubt, dificult matches will come. So thank you once again.
