Very few players will refuse to play once the window's closed, especially with a World Cup coming. If Southampton point blank refuse to deal, come the 1st September some sort of apology will be given and he'll be back playing. As I said last night, the other possible problem could be VvD blinks first and accepts a move elsewhere. As much as it's been reported he wants to join us over whoever else, if it gets to the point where the window is about to close and Southampton accept an offer from Chelsea (for example), does he turn it down hoping a deal to Liverpool can happen or will he take it? He takes it imo.
He's a Dutch centre-back...he could not play for a year and still be the best they have!
