Djokovic renews his epic 16-year rivalry with Rafael Nadal at the French Open on Tuesday with a semi-final spot at stake and where victory could end the 13-time champion's Roland Garros career. Nadal, who will turn 36 on Friday, puts his record of 109 wins and just three losses in Paris, since his title-winning debut in 2005, on the line against the defending champion. The Spaniard was taken to five sets for only the third time in his tournament history by 21-year-old Felix Auger-Aliassime in the fourth round. In the immediate aftermath of that victory, Nadal admitted that not only was this year's French Open at stake for him but possibly his entire playing future.
