Stones does look nailed on to be one of the best centre backs in the league and he does fit LvG's playing style better than any of our senior centre backs, but we'd be complete fools to spend £30m on him. We don't need him at all. If we need a new centre back it needs to be an experienced one to marshal the defence, not one still developing. For Chelsea it makes complete sense because they do need him that badly.
I'm amazed at how under-appreciated Jones is on the ball. Here's a couple of examples of his passing while playing in midfield against Madrid in what was probably our most important game of the season in 12/13. Not exactly lacking composure or vision.
Jones will be a star. Smalling's so dominant at the moment that van Gaal will hopefully overlook his ball-playing shortcomings and McNair looks very, very promising. He deserves a chance. Anyone that performed as he did against Chelsea would be seen as a very promising young centre back - the idea that we're impressed just because he's a United player is rubbish, IMO.
