Novak Djokovic has spoken candidly about the self-doubt that continues to drive him at the age of 39, admitting in a new Amazon documentary that he still questions whether his record-breaking career has been enough. The Serbian star, who holds the men's record for Grand Slam singles titles, says the pursuit of improvement has at times felt like a trap of his own making.
Despite winning almost every major honour in tennis, Djokovic insists he cannot simply be satisfied with what he has achieved.
"I cannot say I feel content with what I have and who I am," he says in the documentary. "I am always looking to be more - better, faster, stronger. Oftentimes I feel I am imprisoning myself."
He goes further later in the film, describing himself as his harshest critic.
"I'm the number one doubter. I'm trying to prove myself wrong more than anybody else."
Djokovic shares the record for most Grand Slam singles titles, level with Margaret Court, after claiming his 24th major at the 2023 US Open. He has reached at least the semi-final stage in six of the last seven Grand Slam tournaments and, in January, became the oldest man in the professional era to reach the Australian Open final.
His wife, Jelena, offers a rare insight into how that relentless drive affects him away from the court.
"He definitely has mixed feelings about his retirement," she says. "He carries that burden that he's never enough. No matter how much he does, it will never be enough. Tennis is a fulfilling place for him - a place where he feels worthy."
How did his childhood in Belgrade shape his approach to tennis?
The documentary traces Djokovic's outlook back to his early years in Belgrade, where archive footage shows him as a boy already describing tennis in terms of duty rather than enjoyment.
"My goal in tennis is to become a champion," he says in the old clip.
Djokovic was a young child during Nato's bombing campaign against Belgrade between March and June 1999. He recalls fleeing his family's building, which had no bomb shelter, and tripping as he ran - only to look back and see a plane drop two bombs on a nearby hospital while his family, unaware he had fallen behind, kept running.
He has described the hardship of that period in stark terms, recalling long waits for basic supplies.
"Pretty much every day, for years, we had to wait in line for bread and milk," Djokovic said in a radio interview in July. "These are defining moments, something I want to portray as a building block for me as a player and a person. There is no regret or resentment. In contrary, it's appreciation and gratitude. Everything in life happens as a reason."
Tennis was an expensive pursuit largely reserved for the privileged, and Djokovic has spoken about his father borrowing money from "wrong people" to keep his early career afloat. When he broke into the sport's elite, his emotional, vocal style on court set him apart from the more reserved Roger Federer and Rafael Nadal, and he was not always warmly received by fans as their rivalry gave way to his dominance.
"I had to suppress a lot of emotions which, later on, surfaced on the court," he said. "On the court, that's where I felt safe and comfortable. It was a familiar ground. Tennis is much more than a game and competition. It is defining ground for who I am as a person."
Is Djokovic close to retirement?
No firm date has been set, and Djokovic has repeatedly resisted the idea that his career is winding down, even as questions about retirement follow every Grand Slam defeat. Federer retired in 2022 and Nadal in 2024, both worn down by injury in their final seasons, but Djokovic has instead trimmed his schedule, competing in relatively few events outside the four majors.
After a straight-sets semi-final loss to Jannik Sinner at Wimbledon, Djokovic said he was reaching the closing stages of Grand Slams with the "tank half-empty," though he affirmed he intended to return to Wimbledon again next year and remained competitive at the highest level heading into his 40s. That defeat came after Djokovic had earlier in the tournament broken Federer's record for men's singles wins at Wimbledon, beating Roman Safiullin in four sets for his 106th victory at the tournament, while going in chasing a historic 25th Grand Slam title against a Sinner defending his crown after a difficult French Open. Djokovic was ultimately outplayed by Sinner in that semi-final but said afterwards he remained confident about future Grand Slam success.
Earlier in the season, Djokovic suffered his worst Grand Slam result since the 2024 US Open when he was beaten by João Fonseca in the third round of the French Open, according to a report on his French Open exit, after which he admitted he was unsure whether he would return to Roland Garros the following year. A separate report on the Wimbledon draw noted he had reached the semi-finals there before losing to Sinner, according to a Wimbledon results report, underlining his continued presence deep into majors this season. Another account from July said Djokovic had committed to at least one more Wimbledon appearance, a further sign he has not settled on a retirement timeline.
In the documentary, Djokovic rejects the framing of his career as approaching a fixed endpoint.
"Why would I talk about retirement when I still keep proving to myself that I can still win?" he says. "As long as I have the drive, the passion, but most of all, as long as I feel like I can be one of the best players in the world, I want to keep going."
He does not rule out one more Olympic push, having won a long-sought gold medal in Paris in 2024, and has said he would like to compete at the 2028 Games in Los Angeles.
"It seems a long way out. I feel like I can make it," he added. "I would like to end with the Serbian flag on my shoulders. It would be a nice way to wrap up something I'm very proud of."
What new details has the documentary revealed?
The film, titled "Novak Djokovic: The Wolf in Winter," has now been given a confirmed release date and distributor, according to a report on the streaming deal, which said Prime Video will debut the feature-length project on 20 August 2026 in more than 240 countries and territories worldwide. An official trailer and key art for the release have also been published ahead of launch, according to coverage of the trailer release.
Separately, a report on 16 August 2026 said Djokovic was dealing with what was described as a "medical malaise" during the Cincinnati Open, with his own comments suggesting the issue could prevent him from continuing in the tournament, according to a report on his condition in Cincinnati. That tournament marks Djokovic's return to Cincinnati after a three-year absence, according to his official schedule published on his website, which also notes he previously won the Masters event in 2018 and 2020.

The Cincinnati Open runs from 13 to 23 August 2026, with Djokovic listed in the field, according to his official schedule. The US Open is set to begin on 30 August 2026, arriving shortly after both the Cincinnati tournament concludes and the new documentary's release window, according to a report on the documentary's scheduling.
