Arsenal boss Arsene Wenger admits there's no guarantee Robin van Persie will pen a new contract.
Van Persie insisted before scoring twice yesterday against Sunderland that he remains committed to the club, but Wenger concedes Arsenal are powerless to make him sign an extension to his current contract which expires in 2013.
"For me, commitment is as long as you are at the club - it is not how long you are at the club," said Wenger. "It means you give 100 per cent until the last day of your contract.
"Robin knows we are ready to talk about a new contract. The ideal situation is he extends his length of contract, but if he does not we have to respect that."
