Arsenal laboured to a draw in a game where some of their best players were forced to the limit physically.
“Yes, I am worried,” Wenger said. “We have a few players on the edge like [Robin] van Persie, of course, and [Theo] Walcott, who had a hamstring alert and [Aaron] Ramsey as well. We’ll see how they respond to 24 hours’ rest. Walcott’s hamstring was picked up during the game but he should be OK. At half-time they said he’s all right.”
