Of the five changes Wenger made from the Saturday's win over Cardiff City, the only two that were enforced were Bacary Sagna (hamstring) and Olivier Giroud.
As reported by Goal on Tuesday, Arsenal had planned to rest Mesut Ozil in addition to Jack Wilshere, Kieran Gibbs and Mikel Arteta but it is understood that the striker has an ongoing knee problem and it was seen as an opportune time to give him a break. Wenger felt that he could not do without both Ozil and Giroud.
Theo Walcott had been primed to make his first start since September 18 but ended up being a substitute for the third consecutive match after struggling with an illness in the build-up to the game.
The Gunners are preparing for a testing six-day period in which they play Everton at home before trips to Napoli and Manchester City.
