Arsenal have already clinched the top spot in their UEFA Champions League group, so they've left out most of their first team plays for their match against Olympiacos. The Greek champions are still fighting for a place in the knockout stages, and could conceivably get it with a draw if things go right in Marseille-Dortmund. The best way for them to get through is win and hope that Marseille do not. Here are the lineups.

Arsenal Lineup (4-2-3-1): Fabianski; Djourou, Vermaelen, Squillaci, Santos; Frimpong, Coquelin; Benayoun, Arshavin, Oxlade-Chamberlain; Chamakh

Olympiacos Lineup (4-2-3-1): Megyeri; Mellberg, Holebas, Papadopoulos, Marcano; Maniatis, Modesto; Torossidis, Fuster, Mirallas; Djebbour

Kickoff is at 2:45 pm ET, 7:45 GMT and 8:45 pm local time.
