‘It’s a long and difficult dream’: João Fonseca on practice, patience and matching Sinner and Alcaraz

Brazilian teenage tennis sensation says he cannot control expectations but is looking forward to challenging the best again in 2026, starting at the Australian Open

‘My dream is to become world No 1, win grand slam titles and make history for Brazil,” João Fonseca says with simple purity as we reach the crux of his huge ambition. Fonseca is 19 and he makes that succinct list of his goals sound almost as casual as a few fun things a more ordinary teenager might aim to do this weekend. But Fonseca is different.

He is a generational talent who, in recent years, has been spoken of as a future superstar amid predictions that he might have the best chance of denting the dominant hold that Carlos Alcaraz and Jannik Sinner exert over men’s tennis. But, as time in Fonseca’s company proves, he is remarkably grounded and mature for his age. Those attributes underline his credentials far more effectively than the hype that has trailed him.
