If Nadal goes all the way to clinch the title, he can script a special record.
Nadal can equal Federer and Djokovic as world number one
The Spaniard can go on to equal the number of times legends Roger Federer and Novak Djokovic have finished the year ranked No.1 in the world.
The ATP year-end world number one ranking is determined by which ever player is top following the final tournament of the calendar year, which is the Paris Masters.
Nadal has a real chance of clinching the feat.
Djoker tops the ATP Rankings, Nadal is second
At the moment, Serbia's Djokovic is atop the ATP Rankings. He has a total of 9,545 points. US Open 2019 winner Nadal is second on the list (9,225). Meanwhile, Federer, who decided to skip the Paris Masters in order to rest, is third (6,950 points).
How can Nadal topple Djokovic as world number one?
If a player reaches the final of the Paris Masters, then he will get a minimum of 600 points.
Notably, winning the tournament will see the player receive 1,000 points.
So if Nadal goes on to beat Djokovic in the final, he will get the additional 400 points.
This will be enough to see him finish the year ranked No.1 in the world.
