Carlos Alcaraz and Jannik Sinner have taken the tennis world by storm, splitting the last eight Grand Slams between them. “I’m seeing you more than my family,” grinned Alcaraz during his victory speech after defeating Sinner in the US Open final to reclaim the World No. 1 ranking after two years. Their back-to-back finals are no coincidence: they hint at a new era of dominance. But this rivalry has sparked bigger conversations, as Roger Federer now faces bizarre backlash after calling out tournament directors over alleged Jannik Sinner bias, throwing fuel on an already blazing fire within tennis circles.

This season, Carlos Alcaraz and Jannik Sinner have turned tennis into a two-man show, splitting the year’s four Grand Slams and crafting one of the fiercest rivalries in recent memory. Each player won two majors, and remarkably, they faced each other in the finals of three of the four Slams. At Roland Garros, fans were treated to an instant classic, as Alcaraz fought from two sets down to defeat Sinner 4-6, 6-7, 6-4, 7-6, 7-6 in a five-hour marathon that now stands as the second-longest Slam final in the Open Era.

Their rivalry stayed red-hot at Wimbledon, where Sinner flipped the script and outplayed the Spaniard 4-6, 6-4, 6-4, 6-4, capturing the title on the hallowed grass. The pendulum swung back at the US Open, where Alcaraz once again stood tall, overcoming the Italian 6-2, 3-6, 6-1, 6-4. What makes this run more extraordinary is their consistency; they have now clashed in the final of the last five tournaments in which they both competed, a staggering display of dominance.

Even outside the Slams, this duel has captivated fans. In Rome, Alcaraz defeated Sinner in a thrilling clay-court final, while at the Cincinnati Open, Sinner was forced to retire mid-match due to fitness concerns, handing Alcaraz another win. Their H2H battles have become appointment viewing, and naturally, the tennis world is buzzing about how this rivalry will shape the sport’s future.

Into this heated atmosphere stepped Roger Federer, who made headlines with a bold theory about the conditions enabling this near-constant rivalry. Fresh off promoting the 2025 Laver Cup in San Francisco, the 20-time Grand Slam champion joined Andy Roddick on the Served podcast to discuss the state of the game. When asked about court speeds, Federer didn’t hold back.

“Yes,” Federer said emphatically when asked if there needed to be a course correction. He argued that court speeds have become too homogenized, forcing players into similar styles of play. “That’s why we, the tournament directors, we need to fix it. We need to have not only fast courts, but what we would want to see is Alcaraz or Sinner figure it out on lightning fast, and then have the same match on super slow and see how that matches up.”

Federer went further, reminiscing about how the ATP once counted only 12 tournaments toward rankings, which encouraged players to compete on their preferred surfaces, producing contrasting clashes. “That’s how the rankings points used to be, remember? Back in the day, only 12 tournaments counted, so everybody would play on their favorite surface. And then they would sometimes meet, and those were the best matches when you had the attacker against a retriever, and now everyone plays similar.”

The Swiss maestro finished with a pointed observation, suggesting that tournament directors intentionally slow down surfaces to favor baseline grinders like Sinner and Alcaraz. “It’s because the tournament directors have allowed with the ball speed and the court speed that every week is basically the same… So that’s what the tournament directors are thinking, like, ‘I kind of like Sinner-Alcaraz in the finals, you know? It kind of works for the game’.” 

The clip went viral, social media lit up, with fans accusing Federer of unfairly hinting at bias, sparking an unexpected backlash and igniting a fiery debate about whether tennis is engineering its new golden rivalry.

Fans criticize Roger Federer over alleged Sinner favoritism

As soon as the short clip from the Served podcast went viral, social media exploded. One fan summed up the sentiment perfectly: “he literally singled out Jannik lmao doesn’t take a genius to connect 2+2 😭😭.” Sinner’s fans immediately flooded the post, turning their frustration on the Swiss icon, Roger Federer, who had casually commented on court speeds and finals matchups. The backlash was swift, sharp, and relentless, as fans dissected every word and implied intention behind Federer’s remarks.

One user penned a detailed critique that cut straight to the heart of the controversy: “For the illiterates who cant read subtext: Roger saying ‘so that they cant beat Sinner’ implies that he thinks ppl choosing slow courts is a way to give Sinner an advantage so that he can reach the final. It’s offensive to say such a thing because it implies that Sinner is only making these finals because of the (supposed) strategic marketing decision to use slow courts, not because he is more talented and hard working.”

The fan continued, highlighting Federer’s perceived bias: “Meanwhile he doesn’t say shit about how this benefits Carlos, and he acts as if it is a given Carlos will reach a final under any condition. And Sinner is just the one receiving extra help (via slow courts) to get to the Sincaraz final. Aka he assumes Carlos is superior and will always reach the final ‘fairly’ with no benefit from courts, but he doesn’t think the same of Sinner. It’s offensive. He could have said ‘so that they can’t beat Carlos’ or just used both of their names, but no. He chose to single out Sinner. Roger this is so distasteful and goes against ur whole ‘I’m the classiest man in the world’ persona.”

Another fan injected humor into the outrage: “This reads as if Alcaraz should go to every final in all tournaments he plays while some court modifications need to be done so other guys could beat Sinner 😹 or maybe I’m reading too much who cares.” The comment struck at the heart of the debate: whether Federer’s statement inadvertently suggested that finals appearances for Sinner were engineered, rather than earned.

To provide context, Sinner is widely regarded as one of the strongest hard-court players in the world. As the tour enters three straight months on the surface, his dominance is clear: last year, he posted a 42-3 record on hard courts, losing only twice to Alcaraz and once to Andrey Rublev. Two of those losses to Alcaraz were on slower hard courts, a minority of matches. On faster surfaces, Sinner’s sheer power and precision make him nearly unstoppable, with a serve that outperforms Alcaraz’s in consistency and effectiveness.

Statistically, the margins tell the story. Sinner holds serve 91% of the time, compared to Alcaraz’s 86%, and wins 77% of points behind his first serve versus 73% for Alcaraz. These subtle but critical edges translate into dominance in the close, high-pressure matches where both men often clash.

Fans continued to weigh in on Federer’s perceived oversight. One noted, “Roger I love you to bits forever but let me remind you you had chosen Zverev as your pupil and it shows even the GOAT can be a little less than far-sighted at times.” Another took aim at the idea of engineered advantage: “As if the best player in the world needed help to reach the final lol,” directing their critique squarely at the Italian.

Amid the chaos, another fan captured the essence of the debate: “Also like,,, he says it himself, ‘for the weaker player, he has to..’ then don’t be weak???? Why are you acting like they’re entitled to win against Sinner lmao it’s a sport.” 

The conversation that erupted across social media reflects the intensity of modern tennis fandom: passionate, analytical, and unafraid to challenge even the sport’s most revered figures. The discourse continues to swirl, leaving Federer’s comments dissected, debated, and immortalized in the digital arena.
