Bit of a strange one if he does go, like. I think Pardew does rate him (those quotes about Kaz tearing shreds out of his S'oton side suggest so) and with one year to go on his current contract I don't see why he'd feel the need to leave now. He's just got back to something approaching fitness and had some minutes in our season closers - this coming season is his 'make or break', if you like.
Even more strange if we're actively looking to sell, mind. I don't think he'd fetch a particularly large fee and his wage packet can't exactly be massive either. He's never been proven as good enough but has never been proven as not good enough either.
