Arsene Wenger has named an unchanged Arsenal side as the Champions League Group F bottom side host group leaders Bayern Munich this evening.

Petr Cech is handed his first European start for the Gunners after being controversially left out in the 3-2 home defeat to Olympiacos, while Hector Bellerin is again given the nod over Mathieu Debuchy at right-back.

Theo Walcott is again preferred to Olivier Giroud in the striker role, despite the Frenchman scoring within minutes of coming off the bench in the 3-0 win over Watford at the weekend.

Giroud is on a defensive-minded bench alongside Debuchy, Calum Chambers and Kieran Gibbs, while Alex Oxlade-Chamberlain also has to make do with a place as a substitute.

For Bayern, the only change made by Pep Guardiola is to bring Douglas Costa into the midfield for right-back Rafinha, a change which is likely to see captain Philipp Lahm drop back into defence.

Arsenal: Cech; Bellerin, Mertesacker, Koscielny, Monreal; Coquelin, Ramsey; Cazorla, Ozil, Sanchez; Walcott
Subs: Macey, Debuchy, Gibbs, Chambers, Arteta, Oxlade-Chamberlain, Giroud

Bayern Munich: Neuer; Lahm, Boateng, Alaba, Bernat; Alonso, Vidal; Costa, Thiago, Muller, Lewandowski
