The Bulgarian striker told manager Martin Jol, also formerly of Spurs fame, that he would win it for the Cottagers and he was proven correct with a 52nd minute goal the only of the game.
"Before the game you hope for a point... but Berbatov came to me and promised me... He said: 'you have to trust me'," Jol said.
"I thought he was joking. But he said it before the match against Stoke (where he scored the winner) and he is a wonderful player.
"It was one of the best wins ever."
He added of Berbatov: "He's a remarkable boy.
"He's a different personality, but he's said it twice now. Against Stoke before the match and he said it again today.
"The only thing he wants is a day off if he scores. I promised him a day off and he scores!
"He looks like he's sulking and sometimes his body language is not great, but you know that he can be a winner, and he can decide games for you."
