On Sunday Djokovic defeated Federer 6-4 6-3 in the final of the Italian Open on clay and is now being touted as the man to beat at Roland Gaross which starts on May 24.
Djokovic has won four ATP World Tour Masters 1000 tournaments in 2015 and is riding a 22-match winning streak, with his last loss coming to Federer on February 28 in the Dubai Duty Free Tennis Championships final.
Even though the Serb is the bookmakers favourite to win the second Grand Slam of the year, Federer believes it is too early to talk about the 27-year-old as the French Open champion in waiting.
The Swiss believes he has what it takes to topple Djokovic in Paris adding that nine time French Open winner Rafael Nadal is inclined to play his best tennis at the French capital and can never be written off.
"You cannot take away the past 10 years," said Federer.
"It's going to be best-of-five sets. We know how tough Rafa is physically and mentally. He is the favourite still to me.
"Novak at this point probably has to win, with the results he's shown this year. It feels similar to 2011 when he didn't lose the whole year.
"Maybe Rafa isn't having the same success as before but nevertheless that remains the situation for me. But it's all talk because in the end his racquet's going to do the talking," he added.
