Rooney is facing an anxious six weeks before learning whether he will
be fit enough to go to the World Cup with England, with Sven-Goran
Eriksson vowing to take the 20-year-old to Germany if at all possible.

Although he has expressed major doubts over whether Rooney will make
it, Ferguson has pledged United will do everything possible to help
the striker, with an oxygen chamber at the club's Carrington training
complex being the latest development.

"An oxygen chamber will arrive here this afternoon," said Ferguson.

"There is no conclusive evidence that it does improve injuries but
there is no evidence against it. It won't do any harm and everything
is worth a try at this stage."

Ferguson confirmed Rooney suffered two breaks to the same metatarsal
when he went over on his foot at Stamford Bridge on Saturday but said
confirmation of the second break would have no effect on the player's
recovery programme.

"The break he has got in the fourth metatarsal is a small fracture
but the one slightly above it is nothing to worry about at all," he
said. "It doesn't affect the recovery, there is no damage there at
all."

Ferguson stated there would be no deadline placed on Rooney regarding
his fitness for the World Cup.

Having reached agreement with Eriksson for the former Everton striker
to continue his rehabilitation in Manchester, Ferguson feels Rooney's
participation in the World Cup will be determined by further scans
later in his recovery programme.

"You can't put a deadline on it," he said. "The scans will tell you
everything.

"In a few weeks time we will send him back for another scan. If it
has healed then we have the progress we want. If it has not healed,
there is nothing you can do about it.

"We will do our very best to get him there. It is in our interests as
well as England's to do that. But we want him to do himself justice
and we will not jeopardise the boy."
