MUNICH (AFP) - Arsenal manager Arsene Wenger admitted his side had "collapsed mentally" in their 5-1 Champions League rout by Bayern Munich on Wednesday.
The under-pressure Frenchman said there were no excuses as the Gunners faced a seventh successive last-16 exit after their latest mauling.
"We conceded the second goal and then the most important thing was that we lost Laurent Koscielny (to injury). We collapsed mentally," said Wenger, who will now face fresh calls for his resignation.
His post-match press conference lasted barely five minutes and was cut short after he answered just a few questions.
"I am not looking for excuses. Overall, I must say they were a better team than us, they played very well in the second half and we dropped our level," he added.
"They were better than us, well done to Bayern. Their third goal was a killer - we had no response.
"It is a shock of course to lose at this level."
Arjen Robben opened the scoring after just 11 minutes at the Allianz Arena when the Dutchman beat Arsenal goalkeeper David Ospina with a fine left-footed strike into the top corner.
Chile international Alexis Sanchez levelled for Arsenal on the half-hour, hitting in a rebound at the second attempt after he had a controversial penalty saved by Manuel Neuer.
But Robert Lewandowski restored the German side's lead after 53 minutes, heading in a cross from Philipp Lahm with Thiago Alcantara adding a third just three minutes later.
Thiago piled on the misery for Wenger's men with his second and Bayern's fourth just after the hour with substitute Thomas Mueller adding a fifth two minutes from time.
