Reports earlier this week suggested United manager Sir Alex Ferguson was ready to sell the striker.
Berbatov told The Sun: “People have not seen the real Berbatov this season and I would have liked to have done more for the club.
“My dream is still to triumph with United and win another league title.
“At Spurs I have scored more goals with less problems and at United it has been more difficult.
“But I do not worry about the critics. In football it is harder to be a forward because people analyse errors more than success. My morale is high and I am always trying to overcome the situation.”
