BREAKING NEWS: Jannik Sinner has caused a stir on social media by claiming that Carlos Alcaraz’s victory at Roland Garros 2025 was due to luck and the bias of the ATP and the umpires. Coach Juan Carlos Ferrero responded immediately with just five words, leaving the world number 1 speechless.
The rivalry between Jannik Sinner and Carlos Alcaraz has reached fever pitch after some explosive statements shook social media and put the tennis world on edge. It all started when Sinner, a finalist at Roland Garros 2025, posted a message on his official X account (formerly Twitter), implying that Carlos Alcaraz’s victory in the tournament final was the result of “luck” and “preferential treatment” from the ATP and the umpires .
The Italian’s exact words quickly went viral:

“When those who should be neutral tip the balance, it’s not the best who wins, it’s the favored who wins.”
Although it doesn’t mention Carlos Alcaraz directly, the context left no room for doubt. The Roland Garros final had concluded just 24 hours earlier, with Alcaraz lifting the trophy after an epic five-set battle against Sinner. However, controversy quickly arose. Many users interpreted the message as a direct accusation not only of the tournament’s refereeing system, but also of the impartiality of the bodies that govern professional tennis.
The reaction from Alcaraz’s entourage was not long in coming. But what surprised the world wasn’t an official statement or a press conference, but rather the brief and forceful response from his coach, Juan Carlos Ferrero , who wrote on social media:
“Speak on the track, not off it.”
Five words that shook the air. The phrase was echoed by thousands of users, sparking a virtual firestorm. Ferrero’s response was seen by many as a lesson in sportsmanship and class, while others interpreted the exchange as the beginning of an open psychological war between two of the most brilliant figures in modern tennis.
In Italy, the press was divided. Some outlets defended Sinner, arguing that there were questionable refereeing decisions during the match, such as two dubious balls that were not corrected despite technological challenges. Others, however, criticized the youngster for not accepting defeat gracefully.
In Spain, most media outlets supported Alcaraz. The sports daily Marca ran the headline: “Ferrero, the bulwark against Italian darts,” while AS was more direct: “Sinner loses the match… and his papers.”
At the international level, tennis legends also spoke out. Former world number one Andy Murray commented in an interview: “We’ve all felt the umpire made a mistake at some point, but accusing the entire system without evidence is dangerous.”
For his part, Novak Djokovic, speaking from Belgrade, preferred to remain neutral: “They are two great players. The important thing is that respect is maintained on and off the court.”
Meanwhile, the ATP has yet to issue an official statement regarding Sinner’s comments. However, insiders suggest an investigation could be launched if the statements are deemed to affect the integrity of the tournament or the institution.
The truth is that this controversy has added a new dimension to the rivalry between Alcaraz and Sinner, one of the most exciting and widely followed in recent years. The two have played memorable matches and alternated at the top of the rankings, earning the respect of millions of fans. But now, the tension has crossed the line and entered the personal realm.
Carlos Alcaraz has not yet made any public statements. Sources close to the player claim he is “upset but focused” and prefers to “speak with actions, not words.”
On social media, fans have already taken sides. The hashtag #TeamAlcaraz quickly trended, while #JusticiaParaSinner also garnered thousands of mentions. Some have even called for a replay of the match or a formal review of the officiating, which seems unlikely.
The next time these two tennis players face each other, it won’t just be for points or trophies. It will be for pride, for reputation, and to prove who truly deserves to be at the top. Indian Wells, Wimbledon, or wherever fate brings them together again, the world will be watching closely .
