Confirmation that Wayne Rooney suffered a hairline fracture of his left foot during Sunday's goalless draw with Reading only worsened an already difficult situation for the United boss. Louis Saha and Ole Gunnar Solskjaer have only just returned to training after long-term problems, while Carlos Tevez is effectively only a week into his pre-season after an extended lay-off following Argentina's Copa America campaign. Ferguson is so short of orthodox forwards he ended up with John O'Shea partnering Cristiano Ronaldo up front against Steve Coppell's men, so it was probably little surprise they failed to find a crucial breakthrough even against a side reduced to 10 men after the dismissal of Dave Kitson. But Ferguson will resist the temptation to splash the cash once more, insisting he is happy with his current options, with Tevez almost certain to be handed his debut against Portsmouth on Wednesday. "Carlos Tevez is available now and Louis Saha and Ole Gunnar Solskjaer are training," said Ferguson. "With Wayne as well, we have four strikers so I am not looking at a situation where I have to add to that number." Nevertheless, the loss of Rooney for an extended period, following hot on the heels of the sales of Alan Smith and Giuseppe Rossi, presents a problem United could well do without. Old Trafford officials have so far declined to reveal either the precise nature of Rooney's injury, nor offer a recovery time. However, given he left the ground with his foot in plaster on Sunday night, it would be a major surprise if Rooney was back in action within two months, ruling him out of a succession of key fixtures for club and country, including four crucial Euro 2008 qualifiers. "There was a bit of swelling around the injury," said Ferguson. "There was no point him continuing because we have a long season ahead." Rooney's injury overshadowed a strange contest in which United dominated and created plenty of chances without managing to put Reading's goal under sustained pressure. Ryan Giggs did hit a post, while the best of a string of saves from Royals keeper Marcus Hahnemann denied Paul Scholes near the end.
