Joao Fonseca emerges as one of the ATP Tour’s standout young talents. In 2025, the Brazilian teenager climbed from outside the top 100 into the top 25, securing his first two career titles. Fans flock to tournaments to catch his matches, drawn by his explosive potential.
Djokovic Champions Emerging Generation
Novak Djokovic, the 24-time Grand Slam champion, hails Fonseca as a future superstar. Yet, he insists two other teenagers—Jakub Mensik and Learner Tien—merit equal attention for their remarkable results.
Mensik, at 19, captured the Miami Open title by defeating Jack Draper, Arthur Fils, Taylor Fritz, and Djokovic himself. In 2026, he advanced to the Australian Open’s second week before an injury forced his withdrawal. He rebounded strongly in Doha, stunning Jannik Sinner in the quarterfinals.
Tien kicked off the previous season with a stunning upset over Daniil Medvedev at the Australian Open and capped it with his first title in Metz. This year, the world No. 25 reached his maiden Grand Slam quarterfinal in Melbourne.
Djokovic on Tien’s Talent and Team
Djokovic praises Tien’s abilities after facing him at last year’s US Open. “I think he’s a very talented player,” Djokovic said. “I played him in US Open last year. Obviously, I think it was the first time maybe night session for him, so maybe he wasn’t playing as good as he can play or that he has played in some matches that he has won against Medvedev, for example, last couple of years in Australia that we have seen, or Miami, for that matter, last year.”
He highlights Tien’s key wins and notes the group’s momentum. “He has had some great performances, and he’s still very young. You know, I think him, Fonseca, these guys, Mensik, that’s the generation. I don’t know if they’re the same age or maybe someone is year younger, year older, but I think Fonseca got a lot of spotlight, which is nice for him, but I think the other guys deserve that too because of the results and everything that have been showing, you know, in the last couple of years, particularly in the last 12 months.”
Tien benefits from coaching by tennis legend Michael Chang, the youngest men’s Grand Slam winner at the 1989 French Open. Djokovic views this partnership favorably. “Tien has Michael Chang in his corner, who is obviously one of the all-time greats and Grand Slam winner and someone that has been on top of the game and understands,” he added. “Also, I think he’s the youngest-ever Grand Slam winner on the men’s side, 16 or 17 when he won Roland Garros, so he understands the pressures that come into play when you’re so young and you reach that height and have that platform.”
Djokovic emphasizes Tien’s strong support system, including USTA backing, positioning him for future success. “It seems like he’s putting a good team around himself… He has all of the precursors of becoming a really good tennis player. So it’s really up to him now, and time will tell.”
