The Bulgarian has signed a two year deal with the Cottagers although the fee is undisclosed.
Berbatov has not got much of a look in at United for some time even though he clearly has the ability to score goals. And now that Ferguson has Wayne Rooney, Robin van Persie, Danny Welbeck and Javier Hernandez at the club, Berbatov stands no chance.
The 31 year old told Fulham's official website: "I'm delighted to have signed for Fulham and I look forward to playing under Martin Jol again.
"As soon as I was aware of Fulham's interest my decision to join was an easy one to make. I'm impressed with the set up here and the people have made me feel welcome.
"There is a close and personal feel around the Club and I can't wait to get started."
Berbatov will wear the number nine shirt.
