For all the jokes about Moyes playing 4 centre halves it is undeniable that this is one of the stronger areas of the squad so it would make sense to play 3 at the back. It would also be a way of playing 2 forwards.Well we don't have anyone who would be a good full back week in week out either, shall we rule out the possibility of playing a back 4 too? Surely whoever the manager is and whatever system they prefer to play, we have to work on the basis that we would be recruiting with that in mind?
