^ Being at home, Mou will most likely let United play more aggressively. I hope we get to see the same squad he deployed vs Chelsea, or at least see Mata play the AM role again and Martial on the left (which he prolly will). 
I think he should stick to the exact formation that he used for the Chelsea game and I heard reports that Sanchez didn't train today which means that he will not be featuring in the game tomorrow and he should be benched until he gets his form back.
