Manchester United boss Sir Alex Ferguson has taken a swipe at Arsene Wenger's transfer policy at Arsenal.
"He believes profoundly in his youngsters," Ferguson told Le Journal du Dimanche. "He doesn't like to blend them too much with older players.
"What astonishes me is that he always buys attacking players, like Arshavin. He is a good player but he already has Nasri, Adebayor, Van Persie, Bendtner, Eduardo, Walcott.
"I don't think he likes buying defenders. That lacks balance."
