I'd be disappointed to see him go, but I'd take upwards of £5-6m. Can't see Spurs going for him though.
I don't see that he has a position in the team with everyone fit because he's never asserted himself in any one position and there are better in every one imo, but the annual injury curse being as it is (Dyer-less this season to his credit), he's often a vital player for us.
