Good team. But I have 3 improvements:
1. Change Ózil, get someone with better pace.
2. Change Villa and Di Maria for proper CAM's (or change their position with Position cards).
3. Try and get a CDM with more pace, I know you have Marcello and Ramos in LB and RB, but pace down the middle will kill you. Pace whores can run straight past them.
Anyway, that's what I'd do. Great team.
