Novak Djokovic has claimed that he is not daunted by the prospect of becoming the first professional since Rod Laver to hold four Grand Slam titles at once.
The world number one can add the French Open to his already-bulging trophy cabinet of Wimbledon, the US Open and the Australian Open.
"This is an opportunity that very few tennis players have in their lives," said Djokovic. "I'm aware of that, but I accept it as a challenge.
"It makes me even more motivated. It makes me feel good about it, rather than feeling pressured and worried if something bad is going to happen. So I'm looking forward to that."
The Serbian professional is due to go up against Italy's Potito Starace in the first round of the Roland Garros, which begins on Sunday.
