Joao Fonseca has not quite enjoyed the breakout season in 2025 that many had anticipated.
The Brazilian teenager burst onto the scene at the ATP Next Gen Finals last December, triumphing over Learner Tien in the championship match to announce himself to the tennis world.
His first full season on tour began promisingly, with Fonseca earning his first Grand Slam victory in a statement straight-sets win over ninth seed Andrey Rublev at the Australian Open.
He then went on to claim his first ATP title at the Argentina Open, and became the second youngest South American player in history to win three Challenger Tour titles with his triumph in Phoenix, older than only Juan Martin Del Potro.
Since then, however, Fonseca has not been able to build on his early success and has failed to win more than two matches at any tour-level event.
The young star recently made the wise decision to skip the Asian swing altogether and is now set to get his indoor hard-court season underway, during which he may find himself in a predicament.
Joao Fonseca needs to be careful with his next big decision
As per Brazilian outlet Universo Online, pressure has been mounting on Fonseca from fans in Brazil, with many calling for him to make a switch-up in his coaching team amid a poor run of form.
Since Roland Garros, Fonseca has tallied a win-loss record of just seven wins to as many losses, having crashed out in the first round of both the Halle Open and the Canadian Open.
- Halle Open: First Round
- Eastbourne Open: Second Round
- Wimbledon: Third Round
- Canadian Open: First Round
- Cincinnati Open: Third Round
- US Open: Second Round
Though Fonseca has stated that he does not plan on making a change in coaches, the pressure may increase in the coming weeks following the draw for the Swiss Indoors in Basel, where he will play next.
In his first tour-level appearance since the US Open, Fonseca has been dealt a very tough draw in Basel, with a brutal first-round tie against defending champion Giovanni Mpetshi Perricard.
Other stars in Fonseca’s quarter of the draw include Miami Open champion Jakub Mensik and Shanghai Masters finalist Arthur Rinderknech.
If Fonseca suffers an early exit at the Swiss Indoors, he might be swayed to consider changing his coach, a decision that could prove costly in the development stages of his career.
Fonseca does not need to worry about what some may view as an underwhelming debut season, as plenty of greats have endured similar starts to their career, including Roger Federer, who did not win a major until his fourth full season on tour.
So long as he does not make any rash decisions from now until the end of the season, Fonseca will give himself the best possible chance heading into his 2026 campaign.
Joao Fonseca’s potential path to the final at the Swiss Indoors
Should Fonseca advance past Mpetshi Perricard in his opening match at the Swiss Indoors, his next opponent is likely to be seventh seed Mensik.
Following Holger Rune’s injury at the Stockholm Open, quarterfinal tests could come in the form of Rinderknech or Marcos Giron.
In the semifinals, Fonseca would have a big test, with Alexander Zverev and Felix Auger-Aliassime making up the seeded spots in the bottom half of the draw.
The first seed in Basel is Taylor Fritz, whom Fonseca could earn revenge against in the final after losing to the American at the Eastbourne Open.
The Swiss Indoors marks a big opportunity for Fonseca to make a deep run at an ATP event, and give himself confidence heading into next season.
