We have to be careful what we wish for. I think Maguire's confidence took a battering after our shambolic tactical approach at the start of the season, and I don't think it helps that his price tag and his prominence for United and England means he is scrutinised far more than other CBs.
I am not here for a back-and-forth argument, so please don't come back at this if it's just going to be all-out negativity. All I am saying is, even now, Maguire is still England's best CB, so if England's best CB isn't good enough for us, who do we go for next?
I certainly can't think of any player currently playing in the Premier League who would be available and is a better CB than Maguire (of course, there are better CBs, but they're not available). Yes, we could look oversees, but I have seen many a mighty reputation shattered when a player moves from another league to the PL, particularly CBs.
My preference would be, get behind Maguire until the end of the season and try to play him into form/confidence alongside Varane. IF we can get Maguire ad Varane working as a partnership, I believe that would be an excellent pairing.
Plus, let's face it, we need a CM and we need a CF. We're not going to be able to address all three positions in one Summer.
