very much this. Quite how Fergie got them to win the title without much of a central midfield has constantly escaped my understanding and now the defense is needing replacing too with Ferdinand, Vidic and Evra all the wrong side of 30 and in the case of Vidic and Ferdinand their replacements nowhere near the same standards. Throw in some amateurish attempts at transfer dealings in the summer by the new chief exec (what were they trying with the prolonged pointless Fabregas chase? Did they seriously think he'd leave Barca so soon after all it took to get back there?) and its no wonder Moyes is struggling.
Sad thing is while there will be protestations of supporting him and giving him time if the champions league place is looking dodgy in February I'm convinced Moyes will be sacked and Fergie back in caretaker charge.
