Arsenal boss Arsene Wenger believes his side had "no luck" in the 2-0 away win against Monaco in the Champions League.
The Gunners dominated Leonardo Jardim's men and came agonisingly close to reaching the Champions League Last 8 stage but were made to pay for their below-par performance at the Emirates.
"We had a good game tonight, but no luck," Wenger said after the game.
"They really surprised us in the first leg when we were too sure of ourselves on the night.
"Congratulations to them, but we are having quite a positive series going on.
"People over analysed the match in a positive way, because if you look at the starts again they did not dominate the game, but played really well on the counter and were not cautious enough.
"After the first goal we were not patient enough. Football is not a fairytale, it is a matter of being realistic and being clinical, maybe a bit lucky as well, maybe that is part of the game.
"If you go out after the group stages, you have no chances after to play again [at this level], like you do in the Europa League.
"If you look at the numbers, we had a 98% chance to be out, but we did fight and produce the game we wanted.
"I felt that some players were a bit jaded offensively because we have given a lot on Saturday and in the second half lacked a bit of freshness to finish the game off.
"If you take a look at the shots on target in the two games, they were well rewarded, and were very clinical. We are disappointed because out of the competition, but we wish them the best of luck.
"It is very, very important [to bounce back] because we want to win the next game."
