Jannik Sinner has confirmed he will return to competitive tennis in December after being sidelined by a right knee injury since winning Wimbledon.
The Italian world number two will make his comeback at the lucrative Six Kings Slam exhibition tournament from December 27 to 30 before targeting the Australian Open in January.
Sinner has been the most significant absentee from the second half of the men's tour this season. The five-time Grand Slam champion has not played a match since lifting the trophy on the grass courts of London, with the knee problem forcing him to miss all subsequent ATP Tour tournaments.
Speaking in an interview with the Italian newspaper la Repubblica, Sinner explained that physical setbacks were an inevitable reality of professional competition. He said athletes had to be sensible and understand how much to play and when to adopt a long-term approach rather than focusing only on immediate results.
He explained that while an athlete must sow the seeds now, the harvest always takes time to arrive. Sinner said that effort and preparation consistently make the decisive difference at elite level, pointing out that while luck can help a competitor win an individual point, it never wins an entire match.
Rivalry with Carlos Alcaraz
During the interview, Sinner reflected on the emotional challenges of his journey in tennis. He described having to leave home at 13 years of age as the hardest moment he had faced, leaving his family to pursue professional tennis training.
Sinner also discussed his relationship with his chief rival, Carlos Alcaraz. The Spanish star reached out directly to Sinner as soon as he learned that the knee injury would force him off the tour for the remainder of the year, sending a personal message to wish him a speedy recovery.
Sinner said that competitors were not all the same, noting that sharp personal and stylistic contrasts brought out the best in both men. He suggested that observers might view him as the disciplined and obstinate champion, while seeing Alcaraz as a flamboyant, Mediterranean presence on the court.
He described that dynamic as the essential beauty of tennis, arguing that players always benefit from having a rival who pushes them to their limits. The sport had always drawn its greatest energy from such pairings, Sinner said, citing the historic clashes between Bjorn Borg and John McEnroe and between Pete Sampras and Andre Agassi, before two-way battles expanded into a three-way contest among Roger Federer, Rafael Nadal and Novak Djokovic.
Debate Over Teenage Athletes in Elite Sport
The Italian champion also addressed the wider debate surrounding young competitors in professional athletics. The issue came to the fore following the breakthrough of 16-year-old Kristina Liutova, who won the WTA 250 tournament in Memphis.
Her victory reignited arguments among officials and commentators over whether age limits should be introduced to restrict young players from senior events, amid concerns that early professional competition could damage childhood development. The Women's Tennis Association operates specific eligibility guidelines designed to manage workload and prevent teenage burnout.
Sinner stated that although he did not establish the sport's regulations, he saw no reason to prevent young athletes from achieving early success. He asked why society should deprive teenagers of a great story to tell after they had experienced intense emotions, fought hard on court and dedicated years of preparation to reach the professional ranks.
Sport gives young people a platform and allows them to be heard at a formative stage of life, Sinner said. He described competition as a vital avenue for adolescents to understand who they are and to mature as individuals.
Support for Young Stars Across Sport
Sinner observed that modern society often refuses to recognize teenagers as adults, frequently telling them in other spheres that they are not old enough to participate. By contrast, he said, sport provides genuine opportunity without judging competitors or asking for identification.
To support his argument, Sinner highlighted the season enjoyed by Spanish footballer Lamine Yamal, who became a world champion with Spain at the age of 19. Sinner questioned why people should fear that youth would cause problems, asking whether it might instead open new horizons and uncover qualities that had never been seen before.
He urged administrators to let young people play, drawing another parallel with motorsport. Sinner pointed out that Italian driver Kimi Antonelli made his competitive racing debut before he was even old enough to hold a road driving licence.
Sinner joked that he had finally managed to earn his own motorcycle licence, before adding that anyone who earns success through hard work should be free to compete. In the same way, Sinner said, veteran icons Lionel Messi and Cristiano Ronaldo have every right to be on the pitch even though they are no longer teenagers, noting that the same principle applies to Djokovic in tennis.
Preparations for the Australian Open
Sinner will now conclude his physical recovery as he prepares for his comeback at the Six Kings Slam event at the end of December. The multi-million exhibition will offer him his first competitive matches in several months, testing his right knee against fellow top-ranked players before official tour competition begins.
His primary target for the start of the new season is the Australian Open in Melbourne, where he will aim to capture another major title. The Italian world number two will look to build momentum from his December return and reassert his place at the pinnacle of men's tennis.
