It's deja vu all over again for Arsenal in the Champions League. Tuesday night's brave but preventable Champions League exit against Monaco was the fifth time in a row Arsene Wenger has been knocked out at the last-16 stage. And once again it was the first leg that cost him. Arsenal were knocked out in France on away goals, a 2-0 away win failing to make up for a catastrophic 3-1 loss at The Emirates. Their players know the history. 'We say same thing every year,’ complained defender Laurent Koscielny. 'Our first game is catastrophic. We have to put it right - play well in two games.' Arsene Wenger vents his frustration on the sideline as Arsenal fall a goal short in their 2-0 win over Monaco . Aaron Ramsey made an immediate impact off the bench and scored but couldn't help the Gunners advance . Monaco celebrate advancing to the Champions League quarter finals as Arsenal fall again in the last 16 . Aaron Ramsey concurred: ‘We’ve always gone out to Bayern Munich and Barcelona at this stage but no disrespect to Monaco, we thought we’d have a good opportunity to qualify. But we gave ourselves a tough test from the first leg. It’s nearly again, but it’s not enough.’ After losing 4-3 on aggregate to Barcelona in 2011 – beating them 2-1 in the first leg before losing 3-1 at the Nou Camp - Arsenal's first leg travails have hurt them every 12 months.

(AC Milan win 4-3 on aggregate) Arsenal were a shambles in the San Siro as Kevin-Prince Boateng, Robinho (two) and Zlatan Ibrahimovic (from the penalty spot) tore them apart. Incredibly, Arsene Wenger's men clawed back three of the goals in the first half at The Emirates through Laurent Koscielny, Tomas Rosicky and Robin van Persie (penalty) but still couldn't force extra-time with Robin van Persie missing from close range. Where did it all go wrong? Fans will remember the Van Persie miss (perhaps coloured by the player's subsequent exit), but it was the mental collapse in the first leg that cost Arsenal. The first goal was spectacular, if avoidable, but the other three were brutally poor defending. Against a decent, but not world-beating attack, the likes of Johan Djourou proved they didn't belong.

Once again Arsenal battled back once they had little to play for and the pressure was off and Lukasz Podolski scored to give Wenger's men a deserved draw in the Olympic Stadium as they chased a shock victory. Where did it all go wrong? Mesut Ozil's missed penalty was the turning point. Before that point they had bossed the game against the European champions.

For all the shambles in the first 91 minutes of the first leg, Arsenal were back in the tie when Alex Oxlade-Chamberlain scored a stoppage-time goal to make it 2-1. For an unimaginable reason, however, they continued to attack all-out, and with nine men ahead of the ball, gave up a shocking third. However wonderful the effort in the second leg, the task was always likely to be too great. Olivier Giroud and Mesut Ozil look dejected as the tie slips away from Arsenal in the first leg yet again .
