Arsenal’s Champions League embarrassment continued as Bayern Munich romped to another 5-1 win over the Gunners, this time a the Emirates.
The result, largely influenced by Laurent Koscielny’s second half red card, sees the Bundesliga side cruise through to the quarter-finals 10-2 on aggregate and will be sure to pile the pressure on Arsenal boss Arsene Wenger.
Trailing by the same scoreline from a first-leg demolition in Munich, the Gunners – with Alexis Sanchez restored to the staring XI – reduced the deficit with a fine finish from Theo Walcott on 20 minutes.
Walcott then felt he should have been given a penalty following a hefty challenge by Xabi Alonso, but the referee waived away the appeals.
Olivier Giroud headed over at the start of the second half, but any hopes of an unlikely comeback were ended when Koscielny was dismissed for bundling over Robert Lewandowski in the penalty area.
The French defender was initially shown only a yellow card, before the referee consulted with his assistant behind the goal and brandished a red.
The Poland forward made no mistake from the spot as he equalised in the 54th minute.
Dutch winger Arjen Robben quickly fired in a second before substitute Douglas Costa’s curling effort and a late double by Chile midfielder Arturo Vidal saw the Bundesliga leaders run riot during the closing stages.
The manner of the defeat leaves more questions over the future of Arsenal manager Arsene Wenger and the direction of his team, who now have only the FA Cup left to target and face non-League Lincoln in the last eight on Saturday.
Real Madrid also moved safely through into the quarter-finals of the Champions League with a 3-1 win away to Napoli, as they secured a 6-2 aggregate victory.
Belgian Dries Mertens had put the Italians ahead on 24 minutes to raise hope of overturning the first-leg deficit.
However, the tie was put to bed with two goals from Real Madrid captain Sergio Ramos in the space of five second-half minutes.
The defender headed in a corner on 52 minutes to level on the night, and then swiftly nodded home from another Toni Kroos delivery.
Substitute Alvaro Morata netted a third from close range in the final minute.
