Arsenal manager Mikel Arteta admits it will be very hard for his team to qualify for the Champions League next season.
The Gunners were knocked out of the Europa League by Olympiacos on Thursday.
And qualifying through the Premier League will be tough considering they are ninth with 11 games remaining.
Asked about their top-four chances, Arteta said: "Very hard because looking at the table we're still far from the objectives that we all have, but we've been far all season from it and we have to keep fighting.
"The most important thing now is that the dressing room has to be strong and we have to keep going and react.
"First of all, I have to convince them about what happened in the game and why they are not through in the tie. If they continue to do that, there will be rewards like we have done in the last 10 games that we played."
