Manchester United Boss Sir Alex Ferguson has expressed his concern for Nemanja Vidic and claimed that the defender will be a doubtful starter in their Premier League clash against Chelsea.

The Serbian also missed Wednesday night's draw against Barcelona due to a stomach bug. But even though he has almost recovered Ferguson is not pinning his hopes too high

"I think he’s doubtful, but we’ll do our best," said Sir Alex.

"He’s back at the hotel, he’s taking plenty of fluids, he had a bit of soup this afternoon for the first time in 36 hours - that’s promising, I suppose.

"Let’s hope we can get him there on Saturday morning - we’ve only got 72 hours to do that, but he’ll want to have a go. He’ll be desperate to play and if we do get him, it’ll be a bonus to us."
