United assistant boss Mike Phelan has confirmed that Wayne Rooney should be fit for Wednesday's Champions League trip to Valencia. Rooney was substituted half an hour from the end of this afternoon's 2-2 draw with Bolton at the Reebok Stadium and Phelan confirmed afterwards the United striker was still being troubled by a niggling ankle injury. That might explain why Rooney was so ineffective and why he still has not scored a goal in open play for the Reds this season. "Wayne Rooney had a bit of a knock," said Phelan. "He has a little issue with his ankle. We don't know how serious. "We will have a look in the morning but we think he will be OK for Wednesday. "He has been playing with it for a couple of weeks now and during the game we decided he wasn't getting into the areas we wanted and he wasn't getting chances, so we had to change it." One man who apparently will miss out on the flight to Spain is Ryan Giggs, with Sir Alex Ferguson confirming the veteran wide man will be out for two weeks after a suffering a slight hamstring strain. "Ryan is the most serious," Ferguson said. "It is a hamstring and I am afraid he will be out for a couple of weeks." Ferguson also decided to rest Rio Ferdinand in preparation for the Valencia encounter and again saw his side concede sloppy goals. Twice they went behind, through Zat Knight early in the contest and Martin Petrov in the second half at a time when the Reds were looking to take control. Although United rallied through Nani and Michael Owen, whose third goal in a week puts Rooney's problems in front of goal into sharp focus, they were unable to take full advantage of defeats for Chelsea and Arsenal yesterday. "In the first half we should have done better but we did well to come from behind," said Ferguson. "The second half was very even. Bolton were a real handful and our chances were reduced but we must take credit for coming back again. It shows a bit of character." Ferguson must now decide whether to stick with Rooney or partner Owen with Berbatov after the former Liverpool star flicked Nani's near-post free-kick into the far corner 16 minutes from time. "Scoring goals has always been part of my career, but this one is tinged with a bit of disappointment at not getting three points," said Owen. "Were helped with a few nice results yesterday but when you don't capitalise fully it is disappointing. "It is a long season and we will bounce back."
