Novak Djokovic described the grueling five‑set, nearly five‑hour marathon that ended his US Open campaign as something he "despised". The emotional toll of that first‑round defeat has sparked a fresh debate about whether the Serbian legend should contemplate retirement, even though his trophy cabinet remains overflowing. For the first time in his career, the 24‑time Grand Slam champion was eliminated in the opening round of the US Open, falling to Argentina's rising star Mariano Navone.

Until that match, Djokovic boasted a flawless 19‑0 record in US Open first‑round encounters and had not lost his opening match at any major since Paul Goldstein upset him at the Australian Open back in 2006. The 39‑year‑old admitted that the underlying health problem he disclosed two weeks earlier is "serious". He insists, however, that he will continue to work on a solution, even as his body shows obvious signs of strain. Throughout the match he appeared physically depleted, suffered frequent bouts of nausea, and doubled over in pain on several occasions.

At one point he fought back tears, yet managed to smile graciously when he congratulated world No. 49 Navone on what was, by all accounts, the biggest victory of the Argentine's career.

Djokovic has previously hinted that his ultimate farewell might come at the 2028 Los Angeles Olympics, where he would carry the Serbian flag one last time. The prospect of an earlier exit, however, has prompted former champions and peers to weigh in.

Former Wimbledon winner Marion Bartoli called the spectacle "sad" and "heart‑breaking", noting that watching Djokovic suffer was difficult for any fan. She emphasized that his physical condition should be the top priority and that comprehensive medical assessments are essential before any decision about his future is made.

British former world No. 1 Tim Henman also shared his perspective. While he described the match as a "tough watch", he stopped short of recommending retirement. Henman pointed out that Djokovic gave everything he could, even when he was up two sets to one with a break in the fourth.

"When you see him vomiting on court and lacking energy, it’s clear he’s battling more than just an opponent," Henman said. Yet he argued that retirement is a personal choice: "If every player ranked fifth in the world retired at 39, there would be no sport left.

He should play as long as he feels able, and I don’t think he should quit now." Henman also addressed Djokovic's mental resilience, noting that his competitive fire remains strong. "His will to win is still there, but the physical challenges of being 39 are undeniable," he added.

He suggested that Djokovic will likely take time away to evaluate his health, because no one wants to see a champion exit a tournament under such distress. American player Ryan Harrison echoed the sentiment that Djokovic is fighting an uphill battle with his body.

Harrison recalled that the Serbian endured a similarly disappointing first‑round loss at the Cincinnati Open earlier in the month, underscoring a recent pattern of physical setbacks. "It's frustrating when your body doesn't cooperate, and you can't enjoy the moments you love," Harrison said. He remains optimistic about Djokovic's future, predicting a return in 2027 and affirming that the Serbian remains one of the sport's top competitors.

Beyond the personal reactions, the broader tennis community is watching closely. The US Open continues to be broadcast live on Sky Sports, with streaming options available on platforms like NOW and the Sky Sports app. Fans can also catch upcoming events such as the Laver Cup at the O2 in London later this September. In summary, Djokovic's recent loss has reignited the conversation about the longevity of elite athletes, especially those who have pushed the limits of physical endurance for nearly two decades.

While his health concerns are serious, many of his peers argue that his decision to retire should be guided by his own assessment of his body and his desire to compete. Whether he chooses to aim for a final Olympic appearance in 2028 or decides to step away sooner, the tennis world will undoubtedly respect a choice made after such a heartfelt and painful experience on the court.
