I'm sure this point has been covered, but do people really see him coming in to the team and not trying to be the "big man", he won't want to be led by Maguire, he'll want to be captain, take penalties etc. I just don't see him being a personality fit at all in a team that currently has a great balance in terms of different characters and team cohesion.
Plus it reeks of bringing in a player who will far exceed the types of wages we really want to pay.
He'll be off to PSG almost undoubtedly, should focus our efforts elsewhere on a longer term signing for that position.
