The big question, so far as I see it, isnt whether Mata Rooney and RvP will play together, thats nailed on, its what Moyes does with Adnan. Theoretically he can play the current system with Mata coming inside off either left or right with either Valencia and Young on the other side, but that feels counter-productive. I honestly wonder whether whether he intends to play Mata and Adnan together or rotate them in the same position. There was no reason not to use Adnan today, other than to rest him, and bringing him on for Mata worried me.
