Injury-hit Arsenal have no fresh worries ahead of their must-win Champions League tie at Olympiakos.

Chile attacker Alexis Sanchez and Spain midfielder Santi Cazorla are among a host of key Gunners players out.

Olympiakos midfielder Esteban Cambiasso may return after injury, with Serbia international Luka Milivojevic or ex-Fulham man Pajtim Kasami giving way.

Former West Brom striker Brown Ideye will return after being rested for Saturday's 4-3 win at Panthrakikos.

The Gunners will qualify for the last 16 as Group F runners-up if they better Olympiakos's 3-2 win in London.

A 1-0 or 2-1 win will not be enough, but 3-2 or a higher scoreline in Arsenal's favour will give them a better head-to-head record than their Greek rivals in the group.

The Gunners would then finish above Olympiakos on overall goal difference.
