Bulgarian Berba's uncle is an exorcist who advised the striker not to sign up for the Red Devils.
The £30.75million buy from Tottenham said: "He is a priest and exorcist back home in Bulgaria - a powerful man who drives out demons and bad spirits.
"When I moved to United he had a problem with their nickname.
"As a godly man, he does not like the name Red Devils."
But now the same uncle has come to be thankful that Berbatov ditched White Hart Lane for Old Trafford.
The Bulgaria superstar - who today faces his old club at the ground where he became a hero - explained: "He has told me that his church has grown a lot bigger. People are football crazy in Bulgaria and if his church is ]more full as I now play for Manchester United, then that is great.
"It doesn't matter what gets them to church as long as they get there to learn from him."
Family loyalties run thick through Berbatov's veins. Believe it or not, he finally decided to walk out on Spurs after a long talk amongst the cabbages and potatoes on his grandfather's allotment.
Behind all the fame and fortune as he leads the United front line in pursuit of a fourth straight Premier League title, he claims to be a simple, home-loving boy who owes everything to his mother and grandparents.
Berbatov, 28, said: "I credit my success to my mother. Her prayers and support are everything to me.
"I know all she does for me and I know nothing I do can ever pay back the amount of support she has given me.
"My grandparents are very important too, my grandfather is a very wise man and a great man to talk to.
"When I am home in the summer I will go to his allotment and help him dig, then we will take the fresh produce home to my grandmother and she will make the most wonderful food.
"The allotment has been the place for some great chats and it was there where we talked about me moving to a club where I could win major trophies and I asked him what he thought about Manchester United."
Berbatov is looking forward to the return to Spurs.
He added: "I enjoyed my time there and the fans were very good to me. But when you hear a club like Manchester United are interested and you have the chance to play in the Champions League, it is impossible to say no.
"I have ambitions and at my age it was the right time to try and achieve those."
he should listen to his uncle la...
