Wayne Rooney injury a blow for Manchester United After his performance on Sunday I think he would have been brilliant today. You don't have two performances like he did on Sunday," said Ferguson. Unfortunately we couldn't risk him. With Danny Welbeck also missing after being taken ill at the team hotel on Christmas night, Ferguson is thankful the minor, if unspecified, knocks that kept Young and Jones out of yesterday's Old Trafford thriller should prove to be short term. "Ashley Young also got injured yesterday and Phil Jones got injured against Swansea," said Ferguson. They should both be OK for Saturday, and I will also have Tom Cleverley and Darren Fletcher, who are fresh. In addition, skipper Nemanja Vidic might be available to shore up United's leaky defence. He was on the bench for the Newcastle victory but Ferguson did not want to use the Serbian, who made his first start since September at Swansea on Sunday. "We couldn't risk Vida after playing his first game," said Ferguson. He had a bit of soreness in his knee, which is only to be expected after being out for so long.
