Stefanos Tsitsipas chooses Joao Fonseca as player of the future: "I see no reason he would under-deliver"
ATP
Stefanos Tsitsipas responded to a press conference ahead of the 2025 United Cup and praised the champion of the Next Gen ATP Finals, Joao Fonseca. Tsitsipas, who got to know Fonseca closely, quickly recognized his potential to break into the ATP Tour and compete at the highest level.
The 18-year-old Brazilian stunned in Jeddah by claiming the title as the 8th seed, the last player to qualify. The world No. 145 defeated opponents like Jakub Mensik (No. 48) and Arthur Fils (No. 20) on his way to the title, joining the list of previous winners such as Jannik Sinner, Carlos Alcaraz, and Tsitsipas himself.
Tsitsipas talks Fonseca’s bright future
Tsitsipas will participate in the United Cup this week, joining former world No. 3 Maria Sakkari for the third consecutive year in search of the title. The Greek team will face Spain on December 28, with Jessica Bouza Maneir and Pablo Carreño Busta as the top singles players. Two days later, they will challenge Kazakhstan, led by 2022 Wimbledon champion Elena Rybakina and Alexander Shevchenko.

During his first press conference in Perth, Tsitsipas recalled his encounter with Fonseca earlier this year. "I was talking to him in Halle this year," he said. "We had a few hours together, he was someone I already saw potential in before he won the Next Gen Finals."
"I was sure he was going to be someone that is going to show big results in the upcoming months," added Tsitsipas, the former Next Gen ATP Finals champion. "I'm happy for him, he’s a very humble kid."
"That's what I liked about him. I had a conversation, and I really liked how down-to-earth he is, how determined and focused on his goals. That is something that definitely stood out," Tsitsipas added.

The world No. 11 further stated that Fonseca has all the potential to rise in the rankings in 2024. "I personally believe it’s just the beginning of him rising up in the rankings and showing his actual true potential," Tsitsipas said. "I think we’re going to see big things from him in the next few years, as long as he stays the same way he is now. I see no reason he would under-deliver."
Tsitsipas' first challenge of the year will be the United Cup, which will be his only preparatory tournament before the Australian Open. He will then travel to Melbourne to compete in the first Grand Slam of the year, where he reached the final in 2023 but lost to Novak Djokovic. The Greek will defend his fourth-round result from 2023, where he fell to Taylor Fritz in four sets.

- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.
mandoist06-11-2026 - Enough of her bullshit. Go marry someone.
mandoist06-11-2026 - Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.
mandoist05-11-2026 - Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.
mandoist05-11-2026 - Vacherot is Mongasque, rather than Swiss. The tournament was Swiss :DTrwd7702-11-2026
- After a couple decades traveling to IIHF tourneys overseas... our family is done with it... and I will not be the only one!! Bad enough the NHL allows Ovachenko (a Putin Supporter and Campaigner) to live and play in the USA. Let's not forget the STATE SPONSORED RUSSIAN DOPING PROGRAMS still in effect today.
mandoist31-10-2026 - Osaka's mental state apparently does not allow her to reach any more Quarter Finals? I mean, she doesn't really have the time for tennis with all the pre-planning that must go into her 12 year-old "fashion" goals.
