Arsenal take on Olympiacos in their final Champions League Group B match tomorrow night with safe passage into the last 16 already secure.

Here we take a look at some of the key clashes at Georgios Karaiskakis Stadium.

THOMAS VERMAELEN v KOSTAS MITROGLOU: With so many of Arsenal's senior men left behind, the Gunners will need a captain's performance from the Belgian centre-half tomorrow night, when he will need to keep close tabs on Greek frontman Mitroglou, who has three Champions League goals.

TOMAS ROSICKY v FRANCOIS MODESTO: Czech midfielder Rosicky is likely to provide the supply link between midfield and attack for Arsenal in Greece, and will have to get the better of tough-tackling Frenchman Modesto.

GERVINHO v KOSTAS MANOLAS: Ivory Coast Gervinho could be given another chance to impress at the head of Arsenal's attack, and Greek Under-21 international Manolas is his most likely shadow.
