Nadal can regain World Number One spot from Alcaraz under these circumstances:

Rafael Nadal can finish the year as number one in the world and it's a clear goal for him and we explain how he can do it.

The race to finish the year as world number one will most likely come down to two Spaniards. Carlos Alcaraz holds the ranking right now with a clear goal of ensuring his first-ever year-end No. 1 ranking. Rafael Nadal has a decent chance as well and it's a goal for him to do as it's a notable thing to do at his age.

Before the Paris Masters began yesterday, Nadal trailed Alcaraz by 920 points but unlike Alcaraz, Nadal has no points to defend. He didn't play at all during this part of the year making every point earned very valuable.

Alcaraz has 90 points to defend in Paris which is not a lot but he could lose his rank even this week if Nadal wins the event and he loses before the quarterfinal. Both of them will keep all of their points from the ATP Finals so it will most likely come down to how they perform this week.

Alcaraz nearly withdrew from Paris due to a knee issue but he will play and ensure us a very exciting finish to the year in terms of who will end up as No. 1.
