Arsenal manager Arsene Wenger has said that his side will "give everything" to ensure that they progress to the knockout stage of this season's Champions League.
The Gunners had been on the verge of an exit from the tournament as they played host to Dinamo Zagreb this evening, but two goals from Alexis Sanchez and a header from Mesut Ozil helped them to a 3-0 win.
The result means that they need to beat Olympiacos by two clear goals in their final group match in Greece next month to make it out of the group, and Wenger has said that his players will do all they can to reach the last 16.
"It promises to be a very interesting game, but at least we have a chance," Wenger told BT Sport.
"I think Mesut Ozil had an outstanding first half, he has got the taste for scoring now. I have never seen Ozil in the box so many times as in the last five or six games.
"The Europa League is not the target - let us give everything to remain in the Champions League."
Arsenal have failed to beat Olympiacos in their three previous European meetings in Greece.
