Rafael Nadal and Novak Djokovic, alonsgide Roger Federer, are considered among the greatest tennis of all time. But who is the best? Former World No. 2 picks and explains his choice.

Rafael Nadal's retirement was marked by a ceremony at the Davis Cup last year, though the event has been widely panned and even Novak Djokovic has had his say

Novak Djokovic is the latest big name from the world of tennis to blast Rafael Nadal’s retirement ceremony. Nadal hung up his racket late last year, with his final-ever match as a professional tennis player coming at the 2024 Davis Cup finals.

Former World No. 1 and 11-time Grand Slam champion Bjorn Borg is probably one of the biggest legends in tennis. However, when it comes to the GOAT debate, he chooses between Roger Federer, Rafael Nadal and Novak Djokovic.

The last time they met, Djokovic defeated Nadal in the 2024 Paris Olympics on the clay courts of Roland Garros (not counting the exhibition at the Six Kings Slam). Tennis fans can follow Sports Illustrated's Serve on SI for all the most important news from the sport.
