AC Milan coach Max Allegri says they won't underestimate Champions League opponents Arsenal.

The Premier League have only two teams in the last 16 after Manchester United and Manchester City failed to get out of the groups.

"I don't think English football is in crisis," the former Cagliari tactician told Sky Sport Italia on Friday afternoon.

"Manchester City, who don't have European experience, were in a tough group along with Bayern Munich and Napoli. Manchester United's exit was a surprise though."

As well as the Rossoneri facing Arsenal, Napoli will take on Chelsea and Inter have been paired with France's Marseille.

"Inter have got the easiest game out of the Italian sides, while it will be difficult for us and Napoli too," he added. "Chelsea are very strong on the European stage.

"We know Arsenal, they are a team who play good football and who are doing well again. We need to get to February in the best physical shape and, hopefully, without any injuries."
