Roger Federer, the Swiss tennis icon with 20 Grand Slam titles, returned to Melbourne Park on Thursday and offered high praise for the burgeoning rivalry between world No. 1 Carlos Alcaraz and No. 2 Jannik Sinner.
Speaking at a press conference just days before the start of the 2026 Australian Open, Federer described their competition as formidable for the sport, highlighting how it has captivated fans and elevated men’s tennis.
“They play incredible tennis and their rivalry is formidable,” Federer said, two days ahead of the tournament’s inaugural opening ceremony, where he will serve as the headline guest. The 44-year-old, who retired in 2022 after a storied career that included six Australian Open crowns, drew from his own experiences facing Rafael Nadal and Novak Djokovic to underscore the impact of the Alcaraz-Sinner matchup.
Federer singled out their 2025 Roland Garros final as a standout moment. In that grueling encounter, Alcaraz, the 22-year-old Spaniard, overcame Sinner in five sets after saving three match points, prevailing in 5 hours and 29 minutes.
“For tennis it was fantastic to have a match like that,” Federer noted. “At one moment, the sports world started looking at Paris and what was happening in that epic fifth set. It ended in the craziest way possible. It was perhaps one of the best matches in the history of this sport.”
The duo, often dubbed “Sincaraz” by fans, has dominated the majors in recent years. Between them, Alcaraz and Sinner have claimed the titles at the last eight Grand Slam tournaments, splitting the spoils evenly.
Alcaraz secured back-to-back French Open wins in 2024 and 2025, along with Wimbledon triumphs in 2023 and 2024, and US Open victories in 2022 and 2025. Sinner, the 24-year-old Italian, countered with consecutive Australian Open titles in 2024 and 2025, plus a US Open win in 2024.
This dominance marks a shift from the “Big Three” era, where Federer, Nadal—who retired in 2024—and Djokovic ruled for nearly two decades. Djokovic, at 38, remains active and is set to compete in this year’s Australian Open, aiming for an unprecedented 11th title at Melbourne Park.
But Federer sees the new generation taking center stage. “That’s why we’re here,” he said of the potential for another Alcaraz-Sinner clash, possibly in the final. “We’re here to see what happens. What we know about sports, anything can happen.”
Alcaraz enters the tournament as the top seed, chasing his first Australian Open crown to complete a career Grand Slam at just 22—the youngest man ever to achieve the feat. He has never progressed beyond the quarterfinals in Melbourne, a hurdle Federer likened to golfer Rory McIlroy’s long pursuit of the Masters.
“He knows about it. It’s like Rory going for the Masters, you know, those things are tough,” Federer said. “His momentum shifts toward the first round, and then it’s point for point mentality.”
Federer expressed optimism for Alcaraz’s chances, saying it would be “crazy” and an “unbelievably special moment for the game” if he succeeded. However, he acknowledged the challenges ahead. “But at his young age, to be able to complete the career Grand Slam would be crazy, so let’s see if he’s able to do crazy this week.
I hope he does, because that would be an unbelievably special moment for the game. But he has another 100-whatever players that say ‘we don’t agree with those plans’, so they’ll try everything to stop him.”
Sinner, the defending champion, is seeded second and seeks a third straight Melbourne title, a streak that would echo Djokovic’s past supremacy. He opens against France’s Hugo Gaston, while Alcaraz faces Australia’s Adam Walton, ranked 79th, in the first round. The draw positions them on opposite sides, setting up a possible final rematch of their intense battles.
Federer, who has hit with both players in practice sessions, marveled at their skills. “I’ve practised with both of them a little bit and they’re incredible ball strikers,” he said. “Their progression in the last few years is wonderful. There’s more to come, I hope they stay injury-free.” He praised their touch and rapid development, adding that the best is yet to come from the pair.
The rivalry extends beyond the majors. In 2025 alone, Alcaraz and Sinner met in six finals, with Alcaraz holding a slight edge in their overall head-to-head at 6-4. Their matches have featured high-octane rallies, tactical depth, and dramatic turnarounds, drawing comparisons to Federer’s own epic duels with Nadal and Djokovic.
Federer reflected on how such competitions drive the sport forward. “It’s good we still live off that momentum and they backed it up by playing each other in all those other finals,” he said. “Everybody else has tried to keep up while they’re trying to pull away.”
Federer’s appearance in Melbourne marks his first visit since his 2020 semifinal loss here, and it comes amid the tournament’s new features, including the opening ceremony on Saturday night. The event aims to celebrate tennis’s history and future, with Federer as the star attraction. “I’m excited to be back,” he said, noting the warm welcome from fans.
When asked about potential coaching roles with either player, Federer laughed off the idea for now. “You can never say never,” he smiled, “but I’m very busy. I have four kids, so for the moment there’s no option.” Instead, he prefers to watch from afar, enjoying the fresh energy Alcaraz and Sinner bring.
As the Australian Open begins on Sunday, all eyes will be on whether “Sincaraz” delivers another chapter. Alcaraz, fresh off his 2025 US Open win, has spoken about his hunger for Melbourne success. “I want to win here more than anywhere,” he said in a pre-tournament interview. Sinner, meanwhile, has emphasized consistency, crediting his back-to-back titles to improved mental resilience.
The tournament draw also features other threats. Djokovic, seeded third, opens against a qualifier and could face Sinner in the semifinals. On Alcaraz’s side, potential challengers include Alexander Zverev and Hubert Hurkacz. Women’s top seed Aryna Sabalenka aims for her third straight title, but the men’s side promises the most intrigue with the new rivalry at its peak.
Federer’s endorsement underscores a pivotal moment for tennis. After years of transition following the Big Three’s dominance, Alcaraz and Sinner have filled the void with flair and intensity. Their matches not only showcase athletic prowess but also strategic innovation, from Alcaraz’s explosive forehand to Sinner’s relentless baseline game.
Fans in Melbourne and worldwide anticipate a fortnight of high-stakes drama. If Alcaraz completes his Slam collection or Sinner cements his hard-court mastery, it could define 2026. As Federer put it, the French Open final was “unreal,” but the Australian Open could push boundaries further.
For now, Federer’s words set the tone: this rivalry is formidable, and it’s just getting started.
