Rosicky back for Gunners

Arsenal will have Tomas Rosicky available again following a hamstring injury for Tuesday night's Champions League clash with Napoli.

The news of Rosicky's return comes as a boost to boss Arsene Wenger, who still has a number of key players missing as the Gunners look to build on their impressive start to the season.

Elsewhere, England forward Theo Walcott has responded well to surgery on a minor abdominal problem, but is now set for up to five weeks recovery time.

Spanish ace Santi Cazorla (ankle), Yaya Sanogo (back), Lukas Podolski (hamstring), Alex Oxlade-Chamberlain and Abou Diaby (both knee) are all still sidelined.
