Carlos Alcaraz has already accomplished more at the age of 21 than most tennis players will in their entire career, but he understands trying to equal what Rafael Nadal did is virtually unthinkable.

After Nadal's career came to an end on Tuesday with Spain's loss to the Netherlands in the Davis Cup quarterfinal tie, Alcaraz told reporters it is "almost impossible" for anyone to follow his legacy:

"I think that he was one of the best ambassadors for tennis. I mean, his legacy is going to be eternal. You know, he has been great for tennis, for this sport in general.

"Yeah, it is difficult, at least for me. I don't want to think that I should continue, you know, the legacy that he has left. It is difficult, almost impossible. I will try to do my best, but right now, you know, it's time to say, you know, just great things about Rafa, what he has done, you know, during his career. Probably he was one of the players that put tennis, you know, in the top of sport in the top of the world. It is just great to have had Rafa in tennis and, you know, in this period in my life."
