Known as the ‘King of Clay’ during an illustrious career in which he won 14 French Open titles, Nadal retires as the second-most successful men’s singles player of all time, behind only Djokovic.

“You have inspired millions of children to start playing tennis, and I think that is probably the greatest achievement anyone can wish for,” said Djokovic, who confirmed he will be present in Malaga to “pay respect” to Nadal’s career.

“Your tenacity, dedication, fighting spirit is going to be taught for decades. Your legacy will live forever.”

While 24-time Slam winner Djokovic is still competing, Federer retired on 20 titles in 2022 – and famously cried alongside Nadal after the Swiss played his farewell tournament at the Laver Cup two years ago.

Among many titanic battles for the sport’s major prizes, the pair contested arguably “the greatest match ever played” in the 2008 Wimbledon final.

“What a career, Rafa! I always hoped this day would never come,” said Federer.

“Thank you for the unforgettable memories and all your incredible achievements in the game we love. It’s been an absolute honour.

Nadal’s compatriot Carlos Alcaraz has already accumulated four Grand Slam titles as the 21-year-old looks to emulate the success of his childhood hero.

Alcaraz, who partnered Nadal in the men’s doubles at the Paris 2024 Olympics this summer, said he was “in shock” after he heard the news shortly before losing in the Shanghai Masters quarter-finals on Thursday.

“Thankfully I saw it an hour before the match, so I had time to accept it. It is really difficult news, even tougher for me because he’s been my idol since I started playing tennis,” Alcaraz said.

The world number two later posted on social media.

“From the child who watched you on TV and dreamed of becoming a tennis player, to the one who had the immense gift of playing alongside you at Roland Garros representing Spain in the Olympic Games!

“Thank you very much for being an example at all levels, your legacy is unrepeatable.

I’ve enjoyed you so much and will miss you so much when you quit after Davis Cup, Rafa!”
