Arsenal ended their Champions League group campaign with defeat at Olympiakos this evening.
The Gunners had already sewn up top spot in Group F and Arsene Wenger made nine changes to the side that won at Wigan on Saturday.
Rafik Djebbour put the home side ahead after 16 minutes by rounding Lukasz Fabianski and finishing from a tight angle.
The Polish keeper was then stretchered off and replaced by Vito Mannone, who went on to make a mistake for the home side's second.
The Italian stopper tried to clear David Fuster's weak shot clumsily with his legs and missed even though he could have picked the ball up with his hands.
Yossi Benayoun pulled a goal back for the visitors with a precise volley ten minutes into the second period but Arsenal were unable to find the equaliser.
Francois Modesto put the game out of reach late on by tapping in after former Aston Villa defender Olof Mellberg's header struck the post.
The Greek side thought they had snatched second place in the group but two late goals in Dortmund from Marseille left the winning side in Piraeus feeling hollow.
