Theo Walcott has still not signed a new Arsenal contract, raising fears that the England winger may be the next big-name star to leave after Robin van Persie's move to Manchester United .
Arsenal manager Wenger admitted: "We are still trying to extend his deal."
Wenger has lost skippers Van Persie and Cesc Fabregas in the last 12 months, and
midfielder Alex Song is also close to a 15 million pounds switch to Barcelona, The Sun reports.
Walcott, 23, has just a year left on his deal.
Wenger added: "When a player doesn't want to stay you either force him or you let him go." (ANI)
