MILAN — AC Milan coach Massimiliano Allegri is wary of Arsenal's strength in attack as the Serie A champions bid to end their poor run against English clubs in the last 16 of the Champions League.

Milan has been eliminated at this same stage of the Champions League by English clubs in three of the past four seasons, with Arsenal beating the Italian champions 2-0 at the San Siro in 2008.

Allegri says "we need to have a game of great intensity, and we can't give them chances to counterattack because that's their strength," although he emphatically adds he is "very confident we'll go through."
