Nadal is one step away from winning his 12th French Open title after beating Roger Federer in straight sets today.
The Spaniard will be boosted by extra rest ahead of Sunday as the Djokovic vs Thiem semi-final has been postponed.
The pair must return to play on Saturday at 11am (BST) – meaning they have just 24 hours between the semi-finals and final.
Thiem leads 6-2, 3-6, 3-1 but Nadal claims not to be too bothered who his opponent is.
FRENCH OPEN RESULTS – MEN’S SINGLES
“Both are rivals of the highest demand, they are number one and four,” Nadal said.
“It’s true that Federer has been playing less for a few years, and taking away from him, Novak, Dominic and I are the ones who have had the best results.
“The opponent is the most competitive possible, but it is the final of Roland Garros.
“That’s the sport and that’s the way it has to be.
“That makes the sport more interesting and better, if I play well I hope my chances are there.”
Nadal also told his supporters that while he is able to dominate other top players on clay he will not consider retiring.
“It can always be the last time but I have not thought about it,” he added.
“That the last time is closer is a reality because we all have the age we have.
“I hope it is not the last and we will play more games like today.
“In the semi-finals of Roland Garros one does not think about the withdrawal, this is a reality.”
