Key Arsenal striker Emmanuel Adebayor is out for three weeks due to the ankle injury he picked up in Saturday's controversial defeat at Stoke. Adebayor sustained his injury in a heavy tackle by Potters defender Ryan Shawcross, while winger Theo Walcott (shoulder) and right-back Bacary Sagna (ankle) were also hurt during the clash.

"Adebayor will be three weeks," Wenger said.

"Walcott could be days or weeks. It is the shoulder he had the surgery on. We don't know about Gallas yet but Sagna will be back in the squad."
