I'd be very surprised if these rumours are true. We saw enough in the first half of the season to say that there is an excellent center back in there. His form fell off a cliff after he came back but there is no reason whatsoever that he cant overcome that. As OB1 says, its not improvement he needs as his ceiling is high, its consistency. I just don't think you jettison a homegrown player who has shown he is capable of the level of performances Stones has put in.
