What motivates Novak Djokovic to endure the intense physical demands of professional tennis? Is it the pursuit of a 25th Grand Slam title, the desire to conclude his career on a positive note, or perhaps something entirely different? A pivotal moment in his 2026 Wimbledon quarter-final against Felix Auger-Aliassime offered some insight.

In the eighth game of the fifth set, with Auger-Aliassime serving at 15-30, Djokovic found himself on the defensive after a powerful forehand from the Canadian. Nevertheless, he managed to respond, scrambling to intercept a crosscourt shot and executing a breathtaking backhand down the line.

This remarkable shot, lauded by the sport’s elite, epitomizes Djokovic’s legacy. The crowd erupted in applause, witnessing a classic display of Djokovic’s skill. After the match, the 39-year-old reflected on the experience, stating, “These are the kind of moments that I still play tennis for,” hinting at deeper motivations beyond mere victory.

Following his disappointing straight-sets loss to Jannik Sinner the previous year, Djokovic had acknowledged the fleeting nature of his career. The toll of 22 years on the professional circuit had seemingly left him fatigued, expressing that he felt his energy reserve was “half empty” even before facing the Italian competitor.

Despite this, Djokovic made a comeback, and this time physical issues weren’t a concern—at least according to his own assessment. After a challenging fourth-round match against world No. 132 Roman Safiullin, which he described as “ugly,” Djokovic admitted, “It wasn’t physical – physical was kind of okay. Just game-wise, I didn’t enjoy my tennis.” His frustration was evident as he displayed anger during the match, later apologizing for his outburst in the post-match interview.

However, all traces of annoyance dissipated as he regained his form in the quarter-final. The match against Auger-Aliassime, which turned out to be the longest in Wimbledon history, showcased Djokovic at his best. The seventh seed expressed his appreciation for the match, noting, “Just one of the best matches I was honestly part of in Wimbledon. I don’t recall playing this long in any match.” He compared it to the memorable 2019 final against Roger Federer, emphasizing the competitiveness of the encounter.

The five-hour and fifteen-minute match concluded just six minutes before the 11 p.m. curfew. The physical toll of such a grueling match remains to be seen as Djokovic prepares for a rematch against Sinner, whom he faced in 2025.

“I wish it (the match against Auger-Aliassime) was the final, so I didn’t need to worry about how the body will feel tomorrow. But I am happy, I am happy that I won,” he remarked.

While many might view reaching his 55th Grand Slam semi-final as a significant accomplishment, Djokovic maintains a different perspective. “It’s just another semi-final for me. I am going to look at all the numbers when I retire. Right now it’s all business, I still have to recover, and I have the best player in the world in a few days’ time,” he stated.

Despite Sinner being the current world No. 1, possessing youth and agility, Djokovic has proven himself capable of competing at the highest level. His victory over Sinner at the Australian Open serves as a testament to this fact.

Statistically, Djokovic thrives on the grass courts of Wimbledon, showcasing a formidable service game. Heading into the 2026 tournament, he had won 77.6 percent of his first-serve points on this surface, a notable increase from his overall average. With this improvement, he has successfully held 89.6 percent of his service games on grass, compared to 86.1 percent on all surfaces.

“I’m still able to battle these young guys that are 15 years younger than me, and I’m able to beat them at the tightest possible scoreline. Of course, in a sense, it is really a nice surprise,” Djokovic commented.

“I always have the highest expectations for myself. I can be very self-critical, very hard on myself. At the same time, I try to also enjoy moments like this,” he added.

As long as he continues to find joy in the sport, Djokovic is likely to keep defying age and expectations.
