Manchester United striker Dimitar Berbatov was again troubled by a knee injury during the 3-0 victory over Burnley at Old Trafford.
The 28-year-old Bulgaria international opened the scoring against the Clarets, but had to be replaced 17 minutes from time, with manager Sir Alex Ferguson a little concerned.
He said after the game:"Dimitar was feeling his knee again. He played through it today, but he could have come off at half-time.
"We will have to look at it again on Monday and see what the situation is
"He was the player who looked most like scoring today.
"A couple of shots went just by the post, he also had a couple of headers over the bar. He had so many attempts he was probably relieved to get one in the end."
Meanwhile, Ferguson accepted that his side had looked nervous against the Clarets, before breaking the deadlock just past the hour mark.
He added:"We could have been embarrassed.
"We had a number of opportunities to punish them in the final third, but there was a bit of nervousness and anxiety about our game."
