Manchester United will face AC Milan in the Champions League without key defender Nemanja Vidic as the Serbian is still struggling with a calf problem. Vidic, who hasn't played since December, joins Anderson and Ryan Giggs out of the squad travelling to Milan on Monday, United said. In the same context, Milan striker Klaas-Jan Huntelaar is strongly tipped to start against the English champions on Tuesday. The Dutchman, who scored twice against Udinese at the weekend, is likely to take Marco Borriello's place as the latter is out with a back injury. "Goals are important, but the most important thing is that I played from the start," Huntelaar told Dutch newspaper Telegraaf. "The directors told me to have faith in myself and I wanted to repay that confidence. I hope to start against Manchester."
