Mikel Arteta admitted Arsenal paid the price for making one big mistake as Bayern Munich's 1-0 victory sent his side crashing out of the Champions League on Wednesday.
Joshua Kimmich's second half header punished slack marking by Arsenal and ended their hopes of reaching the semifinals for the first time since 2009.
The Gunners were beaten 3-2 on aggregate in the quarterfinal after a 2-2 draw in the first leg in north London last week.

It was a painful experience for Arsenal boss Arteta, who bemoaned the defensive slip that proved decisive in the second leg.
"At the moment it is a gutted dressing room. I cannot find the right words to lift them. I wish I had them," Arteta said.

"In moments we have been better but we gave them two goals. That's a big advantage to give away.
"Today you could see the margin of error was zero. We made a mistake defending the box, a big one, and we conceded a goal.
"Then it was difficult. We tried in many different ways but it's difficult."
