The France international thinks he contributes more from a defensive perspective to his team than the Liga stars do for their respective sides
The France international played a key role in Bayern's historic treble win in 2012-13 and has been an impressive form in the opening months of the new season, making him one of the favourites to dethrone the Barcelona star.
"Compared to them, I work much harder. I do a lot more defending than Messi and Cristiano Ronaldo and provide more assists," Ribery told Kicker.
"It would be fantastic to actually win the Fifa Ballon d'Or when you have a shot at winning it.
"I have even more confidence in myself than before and that shows on the pitch. I am on top of my game and score a lot of goals. I am really enjoying myself on the pitch."
Messi has won the Ballon d'Or three times in a row since the award merged with the Fifa World Player of the Year accolade in 2010.
