DAVID BECKHAM has warned Manchester United to watch out for Inter Milan's strike stars.
England ace Beckham played against Inter for rivals AC in the Milan derby last Sunday.
And he thinks forward duo Adriano and Zlatan Ibrahimovic could pose a huge threat to United tonight.
Alex Ferguson's men will be without key defender Nemanja Vidic for the San Siro clash.
Teen stars Fabio Da Silva and Richard Eckersley could make their debuts.
And Beckham said: "Inter have got top players throughout their team but the two forwards are the players who can cause the most problems.
"But United have got great defenders and don't forget, Inter will also be worried about the players United have got in attack."
United are still in the running for an incredible Quadruple this season.
And Beckham added: "I really hope they'll win every one of them.
"It would be amazing if they could.
"It was a fantastic achievement when we won the Treble in '99 and for them to be involved in four competitions this season is brilliant.
"Their squad is so strong all the way through from the goalkeeper to the strikers.
"It's an amazing squad of players and I'm sure they'll go on to achieve great things."
