Stefanos Tsitsipas says that while Rafael Nadal and Novak Djokovic are getting older, they are still as good as ever.
Djokovic and Nadal, along with Roger Federer, have dominated tennis for more than a decade-and-a-half, winning 56 Grand Slam titles between them.
While Federer's current status is somewhat unknown given he has barely played for a year due to a knee injury, Nadal and Djokovic are still producing the goods.
Both suffered relatively early exits at the Monte-Carlo Masters, although it was their first tennis for six weeks and they impressed before their exits.
And Tsitsipas, who has reached the final in Monte-Carlo, has warned that you should never write off Rafael Nadal and Novak Djokovic.
"We're used to seeing Djokovic and Nadal go deep in the tournaments," Tsitsipas said.
"They are getting older but it doesn't seem to bother them at all. They always find solutions to everything. This is what makes them great players - the legends of our sport.
“They seem to be in good shape again, just as they were before, despite taking a two or three-month break."
Djokovic and Nadal will be straight back into action next week in their respective home countries.
Nadal will line-up in Barcelona, while Djokovic will play the new ATP250 event in Belgrade.
