Arsenal go into this match with top spot in Group B yet to be decided. Should the Gunners win and Schalke drop points in Montpellier, Arsene Wenger's side will go through to the knock-out side as one of the seeded sides.
Yet that particular carrot doesn't seem too appealing with the Arsenal manager choosing to leave a number of regular first-team players at home. Theo Walcott, Lukas Podolski, Jack Wilshere, Santi Cazorla, Mikel Arteta and Per Mertesacker have all been rested with one eye on the weekend Premier League match against West Brom.
The match has little significance for Olympiakos either, with progress in the Champions League impossible and a place in the Europa League already assured.
