Rafael Nadal may be in line for a historic 10th Roland Garros title, but he says his ninth victory will always be his sweetest.
Nadal, who is potentially one match away from becoming the first man to move into double figures at a Grand Slam, still rates his 2013 comeback from injury – which led to his ninth title in Paris – as the finest moment of his career.
"It's true that 10 is a beautiful number, but actually my favourite is nine," said Nadal.
"For sure if it becomes 10 it will be my favourite.
"But the thing that I am more proud of in my career probably is 2013. It was amazing."
Many people had written the Spaniard off to knee and wrist injuries three years ago, and considered him a spent force, but Nadal not only returned after seven months on the sidelines, he went on to sweep the French and US Open titles and reclaimed the world number one spot.
"I had too many problems on my knee, so I was not able to practice at all. And I finished the year being World No. 1, winning here (in Paris), winning the US Open. So that's the thing that I am more proud," said Nadal.
The Spaniard has been in imperious form in Paris over the past two weeks, not dropping a single set.

He will certainly be much fresher than his final opponent, Stan Wawrinka, who is coming off a grueling five-set battle against Andy Murray.
Nevertheless, Nadal is wary of growing complacent.
"Nine here is probably difficult. If I did it, probably somebody else gonna do it, because I don't consider myself very special," he said.
"I am not the right one to say, but to play 10 finals here is something difficult."
As for Wawrinka, he's under no illusions over the difficulty of the task ahead.
"To play Rafa on clay in the French Open in a final is probably the biggest challenge you can have in tennis," he said.
"He's the best player ever on clay. He's going for his 10th Roland Garros, so it's something really impressive, something tough.
"I will have to play my best tennis. But again, I did in the past, so we will see what's gonna happen on Sunday."
