^ 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.To me United won the game against Chelsea even the jubilation of Chelsea after their equalizer says it all and the rule of thumb here be don't change the winning team and so I expected United to play as they did against Chelsea and it's great the selfish Alexis will also be sitting out of this match. United can improve even more with this game and can gradually replicate it in the as we move on.
