Juan Martín Del Potro carved out an impressive career during the era dominated by the “Big Three” of Novak Djokovic, Roger Federer, and Rafael Nadal. Del Potro, who famously defeated Federer in the 2009 U.S. Open final, reached as high as No. 3 in the ATP rankings in August 2018.

As a respected voice in tennis, the Argentinian didn’t shy away from weighing in on the GOAT debate. Del Potro declared Djokovic as his pick, putting the Serbian above both Federer and Nadal.

Obviously, the numbers back him up,” Del Potro told ESPN. “Even Novak himself has said he doesn’t care for these discussions. But when it comes down to preferences, some identify more with Roger, others with Rafa. What Novak has achieved in tennis is obviously unmatched.”

Del Potro praised Djokovic’s monumental impact, not only on tennis but on the wider sporting world. “I’m not sure anyone can replicate it,” he continued. “When you look at his personality, his presence—it transcends tennis and becomes part of the history of sports.”

Preparing for a farewell match against Djokovic

On December 1, Del Potro will take on Djokovic in an exhibition match marking the final chapter of his career. The 36-year-old Argentine has battled a devastating knee injury that kept him off the court for extended periods, ultimately leading to his retirement decision.

Djokovic’s historic achievements
