Philippe Mexes admits Milan have “nothing to celebrate. This must never happen again” after their embarrassment at the Emirates.
The Rossoneri risked throwing away a 4-0 first leg lead when they were trailing 3-0 at half-time, but held on to that result in order to reach the Champions League quarter-finals 4-3 on aggregate. 
“The first half went badly and they punished us on every single incident,” said Mexes.
“After the break we were finally able to pass the ball around and we were consequently less afraid.
“This must never happen again. After a game like this, we have nothing to celebrate. We want to progress in the competition, but must do better, even if we got through to the next round tonight.”
