Arsene Wenger's side has secured progression already but must produce a better result than Schalke against Montpellier in order to take first place in the group.
Torosidis, Modesto, Maniatis, Holebas
Machado, Fuster, Abdoun
Jenkinson, Djourou, Vermaelen, Santos
Coquelin, Rosicky, Ramsey
Oxlade-Chamberlain, Giroud, Arshavin
Andre Santos (abdomen) remains a doubt but still could feature at left back, while both Abou Diaby (thigh) and Lukasz Fabianski (shoulder) are definitely out. Francis Coquelin looks set to start for the Gunners in midfield and he could be alongside Tomas Rosicky on his injury comeback, with Johan Djourou also likely to get game time in defense.
Olympiakos boss Leonardo Jardim has effectively no injury concerns coming into the match, although it is essentially a dead rubber for the Greeks too, with Europa League soccer already confirmed.
Avraam Papadopoulous (knee) is set to miss action for the foreseeable future and is the only player definitely missing out, although a couple of those involved in the 2-1 win over Platanias are touch-and-go.
Kostas Mitroglu and Giannis Maniatis both picked up slight knocks before being substituted but it is expected that they will both be available for selection.

The home side has always won this fixture, Arsenal winning three and Olympiakos picking up three victories.
Jardim's team has scored 42.9 percent of its goals in the final 15 minutes of matches.
Olivier Giroud (pictured right) has twice as many assists (four) as Olympiakos' most prolific creator.
The only English side to beat the Greek outfit at home in the Champions League since 2000 are Manchester United, winning in 2001 and 2002.
Olympiakos has lost only three of its last 17 home matches in the Champions League.
Arsenal has managed just six away wins from its previous 17 trips in Europe's elite competition.
Before this season, goalkeeper Roy Carroll had not played a Champions League match since leaving Manchester United in 2005.
The Gunners are currently on 10 points and need to get a better result than Schalke against Montpellier if they are to finish top. Olympiakos will finish third regardless of the result on Tuesday.
