Wenger's starting 11: Mertesacker & Koscielny start / Diaby on bench

Arsene Wenger sticks with the same 11 players who started the game with Norwich last Saturday for tonight's Champions League tie.

That means Per Mertesacker is retained at the heart of the Gunners defence alongside Thomas Vermaelen. Laurent Koscielny continues at right back.

Abou Diaby takes a place on the Arsenal bench for the first time this season following surgery this summer on his ankle.

Arsenal: Szczesny, Koscielny, Mertesaker, Vermaelen, Santos, Song, Arteta, Walcott, Ramsey, Gervinho, van Persie.

Subs: Fabianski, Djourou, Frimpong, Diaby, Arshavin, Benayoun, Chamakh.
