The former world number one, who has her own brand of sweets, was named by Forbes magazine as the world's richest sportswoman last year after earning £15m.
Sam Duvall, who is the agent of 19-year-old Bouchard, told The Age: "Marketability-wise, I think she can be the most famous tennis player in the world. She's got the personality, she's got the game, she's got the looks.
"I really think she has the ability to be more marketable than Maria. She speaks the two languages (French and English) where the four Grand Slams are played."
