Sir Alex Ferguson also believes that Berbatov will improve and be an important player for Man United as the season progresses.
"Dimitar has had a bit of a knee niggle but it is a lot better now," Sir Alex said
"We have been treating him quite carefully because we know that we need him in the important second part of the season.
"He came through a full game against Hull and felt fine. He doesn't need an operation and hopefully that is it gone now."
