Former Manchester United man David Beckham was the last Englishman to receive a harsh lesson at the hands of Inter, losing the Milan derby in the colours of the Rossoneri.

He's warned the Red Devils about the multitude of threats at Jose Mourinho's disposal ahead of the Champions League last 16 first leg clash at San Siro in midweek.

"They have good players all the way through the squad but I think the two forwards are [especially] strong," 'Golden Balls' told The Independent following Milan's win over Cagliari, obviously referring to Adriano and Zlatan Ibrahimovic.

"They are quick, they can hold the ball well and they are not frightened. You have to control them."

Still, he feels that holders United remain favourites to progress. "United have also got players that can win games and their defence is exceptional at the minute," he continued.

"They are [favourites] in my eyes, but I'm biased. They are on a run where they look unbeatable, and I hope that continues.

"I'm on their side because I'm a Man Utd. fan and a Milan player. I'll speak to some of the [United] players and the manager, I'm sure."
