London, Mar 8 (IANS): German football giants Bayern Munich humiliated Arsenal 5-1 to complete a 10-2 triumph in their Champions League knockout stage tie at the Emirates Stadium here.

While few expected the Gunners to prevail after being routed 1-5 in the first leg in Munich, the disgust of the fans at the Emirates after the final whistle on Tuesday was palpable, reports Efe.

This marks the seventh consecutive year, Arsenal has been knocked out of the Champions League in the round of 16.

Already facing a massive challenge, Arsenal suffered a setback even before the match started, as Danny Welbeck injured himself during the warm-up, forcing Arsene Wenger to go with Olivier Giroud up front.

The Gunners made a good start, with Alex Oxlade-Chamberlain and Theo Walcott providing most of the creativity on offense.

Giroud and Hector Bellerin both had chances, but it was Walcott who delivered the goal in the 20th minute to give his side a glimmer of hope against a flat Bayern squad.

Arsenal nearly got a second goal shortly after the restart, but Giroud's header went over the crossbar a few minutes before the incident that turned the match on its head.

Gunners captain Laurent Koscielny brought down Robert Lewandowski in the area in the 54th minute.

The referee pointed to the spot and showed Koscielny a yellow card, but after consulting with the fifth official behind the goal, he swapped the yellow for red and ejected the Arsenal defender.

Lewandowski converted the penalty and the floodgates opened, as the demoralised and shorthanded Arsenal squad went on to concede four more goals in the team's worst-ever loss at the Emirates.

Arjen Robben scored in the 65th minute, capitalising on a poor clearance by Gunners goalkeeper David Ospina. Ten minutes later, a mistake by Granit Xhaka led to Douglas Costa's goal to make it 3-1 for Bayern.

Arturo Vidal tacked on two more goals, in the 82nd and 85th minutes, to push the aggregate score to 10-2.
