Midfielder Aaron Ramsey says the Arsenal players are bitterly disappointed following the mid-week exit from the Champions League but are ready to move on and focus on the Premier League.
With nine games left in the domestic league and Newcastle United coming up on Saturday, the Gunners are in a strong position to qualify for next season's Champions League but are also ready to attack Manchester City for second place.
"No disrespect to Monaco, but I thought we'd have a really good chance of qualifying," Ramsey told the club's official website.
"We were given a tough test from the first game.
"It's not an easy place to come and their record has shown that. We've been full of confidence recently and we knew we could come here and give it a real go to maybe qualify, but we came a bit short in the end.
"We're obviously disappointed that we didn't qualify. We won 2-0 and gave them a good go. On another night we may have got three or four but it wasn't to be.
"We have to learn to keep ourselves in the game in the first leg.
"That's what we've been punished for again this year. We need to be a lot more wise in the first game then go to places like this and win. That's the main thing that we need to put right as quickly as possible.
"We can take some positives from [the second leg]. We have a game against Newcastle at the weekend and hopefully we can continue this winning run that we're on."
