“My dream is to become No. 1 and win a Grand Slam”: Joao Fonseca outlines his long-term vision

Less than two weeks before the start of the Australia Open, concerning news emerged for 19-year-old Joao Fonseca, who was forced to withdraw from the Brisbane International due to a back issue. The Brazilian had been scheduled to begin his 2026 season this week as part of his preparation for the year’s first Grand Slam, but physical discomfort led him to take a precautionary break.

Despite the setback, Fonseca remains in preparation for the Adelaide International next week, although the full extent of his injury has yet to be confirmed. The teenager was present in Brisbane for promotional activities but ultimately pulled out of the tournament at the last moment.

At this stage, the injury does not appear to be serious, with the decision widely viewed as precautionary. Fonseca is still entered in Adelaide, suggesting he is aiming to test his level on court before heading to Melbourne for the Australian Open.

In a recent interview on the Inside-In Podcast, Fonseca spoke openly about his long-term ambitions, setting bold goals despite his young age and recent physical concerns. “I’m still young, it’s my first year, but what helps me a lot to stay motivated is my dream — to become No. 1 and to win a Grand Slam,” Fonseca said.

One year ago, Joao Fonseca was already turning heads at the Australian Open. In the weeks leading up to the first Major of the season, he won the Next Gen ATP Finals undefeated and then claimed the Canberra Challenger title. Arriving in Melbourne as a player seen largely as a future prospect, few expected what would follow.

At just 18 years old, Fonseca stunned Andrey Rublev, then world No. 7, in the first round — securing his first career win over a Top 10 opponent and instantly announcing himself on the big stage.

Since then, the Brazilian has continued his rapid rise. During the 2025 season, he captured his first ATP titles at the Argentina Open (ATP 250) and the Swiss Indoors Basel (ATP 500), cementing his status as one of the Tour’s most exciting young talents.

Reflecting on the whirlwind nature of life on tour, Fonseca admitted that success often leaves little time to pause. “It’s very strange — when you win titles and keep jumping from tournament to tournament, country to country, you can’t really enjoy it,” he said. “After the year ended, I had two weeks of vacation and reflected a little. It’s amazing to see what I achieved, but I’m always hungry for more.”

While Fonseca stressed that it is still early in his career to set short-term expectations, his long-term vision is already clear — and demanding. “Every tough day, when I’m tired or I don’t even want to look at my racquet, I remind myself that I have a future and a dream — to become No. 1,” he explained. “That’s super, super difficult. Only a few guys can do it.”

“That’s what motivates me on the tough days, and also on the good days — to stay motivated and keep working hard. For me, that’s the key.”

Fonseca is currently set to arrive at the Australian Open as the No. 27 seed, although early-season back issues prompted his withdrawal from Brisbane this week. Still, his planned participation in Adelaide should provide a valuable opportunity to assess his form before the Happy Slam begins.
