Nadal is keeping tabs on Alcaraz, who still has a long way to go to achieve anything close to what his fellow Spaniard did on the court.

He hasn’t been the only ATP Tour star to hang up his racket in recent times, with Diego Schwartzman recently opting to follow Nadal into retirement.

Andy Murray meanwhile also retired last season, but made a quick return to coach his former rival Djokovic.

“Great competitor, great champion, great ambassador. An honour to share your final match, amigo. Take a bow.”

Nadal meanwhile posted on Instagram: “We experienced great battles on the track and very beautiful moments with Spain at the Davis Cup!

“Congratulations on your great career, Fernando Verdasco! I hope you can continue to enjoy your family and your new challenges even more. See you all soon!”

Replying to his compatriot, Verdasco said: “Thank you so much family. You are loved and missed! Hopefully we can see each other soon.”

And in singles, a total of seven titles went his way, with the former world number seven particularly shining on clay.

The Spaniard won on the surface on home soil at the likes of Valencia and Barcelona, while there were also a handful of hard-court successes.

It’s clear to see he has left quite a mark on many tennis greats, with German icon Boris Becker also among his well-wishers.

Reacting to footage of Verdasco waving farewell on court, Becker wrote on X: “Congratulations Fernando on your excellent career amigo!”
