Bayern blitz leaves 10-man Arsenal in tatters

Bayern Munich condemned Arsene Wengerto more humiliation as 10-man Arsenal were eliminated from the Champions League with a crushing 5-1 defeat amid furious protests against the beleaguered Gunners boss on Tuesday.

Aiming to stage an incredible recovery from a 5-1 first leg deficit, Wenger's side briefly looked capable of a famous escape act when Theo Walcott opened the scoring in the first half at the Emirates Stadium.

But any hopes that Wenger's recent problems would be erased in historic fashion were brutally dashed by Robert Lewandowski's second half penalty and Laurent Koscielny's dismissal for conceding that spot-kick.

Wenger cut a forlorn figure as Arjen Robben and Douglas Costa netted before Arturo Vidal's double fired Bayern into the quarter-finals with a 10-2 aggregate victory.

It was the first time Arsenal had conceded five at the Emirates and by the closing stages, there was a funereal atmosphere on an evening that started with Arsenal fans staging a protest march calling for Wenger to quit and ended with a chorus of boos and banners held up proclaiming: "Enough is enough — Wenger out".

It was yet another chastening experience in the Champions League for Wenger, who has now seen Arsenal eliminated in the last 16 for seven successive seasons.

Taking possession wide on the right flank, Walcott advanced unchecked by the ponderous Bayern defence in the 20th minute and, from an acute angle, he unloaded a powerful strike that flashed over Manuel Neuer's unconvincing attempted save and into the roof of the net.

Walcott had a penalty appeal turned down after Xabi Alonso caught the winger and he was close to a second goal when he surged onto Shkodran Mustafi's pass before firing into the side-netting.

When Lewandowski got behind Koscielny in the 55th minute, the Arsenal defender's panicked response was to trip the Pole, conceding a penalty and earning himself a red card.

Lewandowski picked himself up to send David Ospina the wrong way with a clinical spot-kick and the Emirates immediately fell into anarchy.

Faced with an inevitable exit, Wenger retreated to the dug out as insults rained down on him from frustrated fans.

Bayern's second goal in the 68th minute came about after Alexis Sanchez was caught in possession on the edge of his own penalty area, with Robben gleefully picking the Chilean's pocket before slotting past Ospina. That opened the floodgates and Costa curled home in the 78th minute before Vidal punished woeful defending to make it four two minutes later.

With Arsenal's players just waiting to be put out of their misery, Vidal waltzed through to make it five in the 85th minute and Wenger's agony was complete.
