Arsenal striker Robin van Persie enjoyed an hour in a closed doors match against MLS club Colorado Rapids yesterday.

However, Theo Walcott collected a thigh injury during the friendly and manager Arsene Wenger told Arsenal TV Online: "From Tuesday night we lost Abou Diaby. He has got a problem on his other calf.

"(On Thursday) we also lost Theo Walcott. He played against Colorado Rapids and he got a little thigh problem.

"Robin played an hour and he looks OK. But it looks early for him, he finished the game very tired today so I will have to analyse that.

"We have a little chance to get Kolo back in the squad and a little, little chance to get Song back.

"As for Tomas Rosicky, it is difficult to say. We hope he'll be back in 10 or 12 days."
