Arsène Wenger has allayed any fears about the injury Robin van Persie picked up at Derby on Monday night.

The Dutchman scored seven minutes before the break to give the visitors a 2-1 lead. But he was substituted at the interval because of a thigh problem. Van Persie has been sidelined with injuries to both his thighs in 2008 but, speaking after the game, his manager was not overly concerned.

"It was his thigh," said Wenger. "But the substitution was precautionary. There is no problem."
