With Wednesday night’s clash against Olympiacos one of Arsenal’s biggest of the season so far.

On the brink of Champions League elimination, Arsène Wenger’s side must win and win well in Greece in order to qualify for the knockout stages yet again.

In the last five years Arsenal have played Olympiacos away from home as the last game of the group stage on three occasions and lost all three. However, none of those games had much riding on them so Wenger rotated his side hugely.

After a 3-1 win against Sunderland at the weekend, he’s made just one change, bringing Theo Walcott in for Alex Oxlade-Chamberlain.

Arsenal: Čech; Bellerín, Mertesacker, Koscielny, Monreal; Flamini, Ramsey; Walcott, Özil, Campbell; Giroud.

Subs: Ospina, Gabriel, Debuchy, Gibbs, Chambers, Oxlade-Chamberlain, Iwobi.

Olympiacos: Roberto; Elabdellaoui, Da Costa, Siovas, Masuaku; Kasami, Milivojevic; Fortounis, Seba, Pardo; Ideye.
