Berbatov struck twice in victory over West Bromwich Albion on Saturday.
Jol said: "I didn't expect a player like him who could play all over the world to come to Fulham. He knows he will play a lot of games for me and that was great.
"The only thing he said was: 'Do you think they (the fans) will like me?' I said: 'I think they will love you.' I think they love him already."
