Former Manchester United and AC Milan goalkeeper Massimo Taibi is reluctant to make a prediction tonight. United are at the San Siro for the first-leg and Taibi believes tonight's game will be decisive over the tie.

"Manchester United, both at home and abroad, I think plays the same game, AC Milan at home deserves respect, I think it will be a good game," said Taibi.

"I think the problem will be Wayne Rooney. He's a complete player, fights, makes goals and defends. Like Milan, however, they have a great team and there are many players who can make a difference like Berbatov and Valencia.

"Without a doubt I am a Milan fan.

"I believe Ronaldinho can decide this tie. He can make the difference."
