Wenger concerned by Walcott knee injury

Arsenal's win over Bolton appeared to come at a cost, with manager Arsene Wenger revealing Theo Walcott picked up a knee injury.
The Gunners finally found some form in front of goal, with captain Robin van Persie netting his 100th goal for the club in the 3-0 win, but they may be without Walcott for Wednesday's Champions League clash against Olympiacos and next Sunday's north London derby at Tottenham.
"I don't really know what happened with Theo,'' Wenger said. "I thought it was a classic hamstring injury but it is not.
"He felt a sharp pain in his knee. I don't know what the diagnosis will be but it was completely surprising. I don't know if he will have scan tonight. I will have to speak to the medical staff.''
Wenger was full of praise for his captain, as he said: "Robin is a man who speaks his mind. I think he is one of these guys who develops with responsibilities. You would think he is not a natural captain at the start but he really has grown well into the role. I have observed him and he does well there.''
