Sir Alex Ferguson has vehemently denied recent press reports that right-winger Antonio Valencia requires an operation on his ankle.
Valencia, 26, had a plate inserted into his ankle last year and the reports suggested it would be removed shortly, but the Scottish manager denied that this was the case.
"I don't where the story about the plate coming out of his ankle has come about - it's never been on our agenda, it's never been discussed," Sir Alex said on Friday.
"We know he has a plate in his ankle, but at the moment it stays there.
"As far as his form is concerned, what can I say? He's been unbelievable since he's come back. He's been brilliant.
"When he first came back into the fold after long term injury I put him at right back occasionally with Nani in the forward position.
"Once he got a few games behind him his form has been tremendous. When you get players who are hitting form at this time of year, their best form as well, it's a bonus."
Ahead of Sunday's encounter with QPR, Ferguson was unwilling to make predictions and believes QPR have shown that they have enough about them to trouble United.
"I'm not going to get into (predictions about the league title). I think we have to concentrate on the game ahead and the game ahead is QPR on Sunday at Old Trafford - we just need to focus on that," he said.
"We have to respect QPR because their last two results have been fantastic, beating Liverpool after being 2-0 down and beating Arsenal 2-1. They are very good results for them.
"Knowing Mark Hughes, he's a fighter and his team will fight for survival.
"As much as I am looking forward to the game it's going to be a hard one. We expect a hard one, that's the best way of looking at it."
