This will be their 42nd meeting across a net since they first played each other in the French Open´s quarter-finals in 2006.
Nadal leads 22-19 overall, 8-3 at majors, and 5-0 in the French Open... but Djokovic won their last four matchups, including on clay in the final at Rome last month.
If Rafa prevails today, he will become the first man in history to win a slam title 10 years in a row. He is also trying for his fifth French title in a row. No one has done that, either... And can tie Pete Sampras at 14 major titles, behind only Roger Federer's record for men of 17.
Nadal´s record at the French Open is 65-1, including a record 34 straight wins.
A victory today would make Djokovic only the eighth man in history to complete the career Grand Slam.
