Southampton would never agree to that. Why sell him for a fee now which would be significantly less than what he'd be worth if he signed a new deal and helped keep them up? I can see him leaving in a couple of years, not now though. There's no reason for him to want to leave. I wouldn't say he's 'excelled' - He's had a (at times very) good half a season. Like I said, he's got great potential - But moving to us at this point in his career would hinder him, rather than help him progress. The only way he'll achieve 'greatness' as you call it, is by being the no.1 LB - something that I don't think he'd be able to do here (not yet, anyway). Van Aanholt has been having a great season at Vitesse by the way and could quite easily cover the third (or even second) left-back position in the squad. As I said, I may be a bit biased, because i've always liked watching him.
