"Vidic is only doing endurance work. He's not played since November 22, that was his last game. He's got a programme with the fitness coach in terms of doing almost like pre-season work. It's difficult to say [when he will make his debut]. It depends on how he comes through the next week or so, when we will have a better idea.
"He won't be involved on Sunday nor next Wednesday at Blackburn. The age of he and Evra are good ages, 24 years of age and they're developing. "
