Arsenal boss Arsene Wenger has urged the club not to unravel after their humiliation at AC Milan.

Wenger must lift his squad again for what is now a crucial FA Cup fifth-round tie at Sunderland on Saturday ahead of the north-London derby with Tottenham.

Wenger said: "The season is not finished. We have a big game on Saturday and it is a good opportunity to show we have character and mental strength, that we can respond after such a shocking defeat.

"You could blame and blame, but we have to stick together and win the next game.

"A big disappointment like that has consequences on your belief.

"We have a lot of work to regroup and not a lot of time to prepare for Saturday's game, when we need to show something completely different."
