It all depends where
Moyes plans to use Mirallas IMO. Or more to the point where is his best position? Can see
Moyes trying him in all attacking positions in next couple of games which might dictate who does come in.
Is he a striker or a attacking midfielder? Do we need a RM now we have him? If that is the plan another Striker is a must. But if Moyes plans to use Mirallas as a 2nd striker possibly, then a RM is a priority.
Having said that Fellaini has that position nailed down after yesterday I would imagine, in which case another quality CM could then be a priority!?!
Very difficult to guess what Moyes will do, or what he thinks he needs really
