João Fonseca, 19 years old, has been the most mentioned figure in men's tennis last week after winning the ATP 500 in Switzerland, especially as he is likened to the "new Novak Djokovic," who might end Carlos Alcaraz and Jannik Sinner's dominance.
Just as Djokovic once broke the Federer–Nadal duopoly to form the legendary "Big Three," many believe Fonseca is on track to rewrite the current tennis order. Alejandro Davidovich Fokina, who recently lost to him in the Swiss Indoors Basel final, even said after their handshake: "You will be the next Nole, the one who defeats Carlos and Jannik."
From teenage sensation to ATP breakthrough star
João Fonseca first drew attention in 2023 when he debuted on the ATP Tour at the Rio Open at age 16, then rapidly climbed to number 1 in the ITF Junior world rankings, a first for a Brazilian player. One year later, he won his first ATP match and claimed the Next Gen Finals title, concluding a remarkable 2024 season.
In 2025, his first full ATP Tour season, Fonseca caused a stir: defeating Top 10 player Andrey Rublev in the opening round of the Australian Open, then winning the Argentine Open, becoming the youngest Brazilian to win an ATP title. Despite a mid-season pause, he came back strongly at the end of the year with a convincing victory at the Swiss Indoors Basel, his first ATP 500 title.
Notably, this is the first time since legend Gustavo Kuerten’s 2001 Cincinnati Masters win that Brazil has had a champion above ATP 250 level. The fast, flat courts in Basel suited Fonseca’s powerful groundstrokes and enduring movement, two traits that experts compare to Djokovic in his early career.
Joao Fonseca regarded as the new Djokovic
Winning in Basel lifted Fonseca to world No. 28, just two years after his ATP debut. Compared to peers, he is on the right path: Alcaraz finished his first season ranked 32, and Sinner was 37. Fonseca said all progress is planned: "We carefully programmed each stage. I skipped the Shanghai Masters to conserve energy. The goal is to be seeded at the 2026 Australian Open, and now I’m very close."
Strong support system, the secret behind Fonseca’s rise
Behind this successful journey is the Fonseca family, who quietly nurtured his tennis dream since he was 4 years old. João was born in August 2006 in Ipanema, Rio de Janeiro, where his home is near the Rio de Janeiro Country Club, a renowned sports center in Brazil. It was there that young Fonseca first held a racquet, fascinated by hitting shots and spending hours daily by the net.
His father, Christiano Fonseca, is a well-known businessman and financial investor, CEO and co-founder of IP Capital Partners, Brazil’s first independent hedge fund managing assets worth $1 billion. Although not from a sports background, Christiano understands the importance of long-term investment, applying this principle in both work and his son’s career.
João’s mother, Roberta Fonseca, has athletic roots. She was a youth volleyball player in the 1980s and still plays volleyball regularly at home. Roberta was the first to accompany Fonseca on his early international tours. “Since I was 11, I only competed with my mom,” Fonseca shared after his Basel win. “She’s always by my side, taking care of every meal and every sleep. This title is for her.”
The Basel victory was even more special with the whole Fonseca family present. His father, mother, and uncles all attended in person. João emotionally recalled: “My parents just flew in from Brazil. They planned to go to Paris but changed flights and arrived in Basel only an hour before the final. It’s amazing they were here to witness the biggest title of my career.”
