As the tennis world pivots its gaze towards Flushing Meadows, the air is thick not only with anticipation for the final Grand Slam of the year but also with lingering questions surrounding the health and rivalry of its brightest young stars. Following a dramatic, albeit truncated, Cincinnati Masters, the spotlight remains firmly fixed on Jannik Sinner and Carlos Alcaraz. Offering his seasoned perspective, Ivan Ljubicic, former world No. 3 and ex-coach to the legendary Roger Federer, has weighed in on the delicate balance of form, fitness, and strategy that will define the upcoming US Open.
Sinner`s Setback: A Race Against Time?
Jannik Sinner`s abrupt withdrawal from the Cincinnati semi-final due to illness sent a ripple of concern through his burgeoning fan base. While the specifics of his ailment remain somewhat guarded, Ljubicic`s analysis highlights the critical nature of recovery time leading into a Grand Slam. “It depends on how long it lasts,” Ljubicic stated, encapsulating the anxiety of millions. “If he recovers in 2-3 days, there will be no repercussions. But if he has to rest for an entire week, then it becomes complicated to regain the necessary form to win a Slam.”
The US Open, notorious for its demanding hard courts, intense heat, and suffocating humidity, is a grueling test of endurance. Even with potentially “more manageable” early rounds, the best-of-five set format coupled with New York`s relentless conditions could, as Ljubicic warns, “make him lose a lot of energy.” It’s a subtle nod to the fact that even the fittest athletes are but human, susceptible to the whims of their own physiology.

The Rivalry Redux: Cementing Legacies on Concrete
The prospect of a third Grand Slam final between Sinner and Alcaraz—a rubber match, if you will, after their French Open and Wimbledon clashes—is the dream scenario for tennis aficionados. Alcaraz triumphed on the clay of Paris, Sinner on the grass of Wimbledon. The hard courts of the US Open present the decisive arena. While acknowledging the difficulty of forecasting a match weeks in advance, Ljubicic leans towards an even playing field on hard courts.
He notes Alcaraz`s 5-2 lead in their cement encounters (excluding the Cincinnati non-match) but counterbalances this by stating, “at the same time, the best Sinner expresses himself on this surface.” It`s a pragmatic assessment, cutting through the hype to highlight the technical nuances. Both players are aggressive, but the specific characteristics of the US Open courts—typically fast, punishing high trajectories, and rewarding exceptional movement—will test their adaptability. Ljubicic points out that Alcaraz`s signature top spin and drop shots might be “less effective” in New York compared to slower surfaces, emphasizing the importance of a strong serve.
“They are clearly ahead of everyone else,” Ljubicic declares, underscoring the dominance of this burgeoning rivalry. “I would be surprised if they didn`t make it to the end, with the question mark of Jannik`s health.”
Beyond the Duopoly: Who Dares to Challenge?
While Sinner and Alcaraz occupy the top tier, the “fluid situation” of challengers, as Ljubicic describes it, mirrors the era of the Big Three. Names like Fritz, Zverev, and, of course, the ever-present Djokovic, are cited as potential disruptors, their performance hinging on current form. For Italian tennis, Ljubicic also offered a brief assessment, suggesting Musetti is seeking to regain his Roland Garros form, while Cobolli might emerge as a surprise.
The Unseen Opponent: The Relentless Calendar
Perhaps the most poignant part of Ljubicic`s commentary revolves not around individual players, but the systemic pressures of the modern ATP Tour. He dismisses notions of Sinner`s inherent physical fragility, attributing past issues to isolated incidents (hip, elbow fall, a presumed virus). His true critique is reserved for the demanding schedule and extreme playing conditions. “When the Masters 1000s lasted a week, players could better manage recovery and training times. Now it`s much more difficult,” he laments.
The Cincinnati incident, in particular, served as a stark reminder. “I can`t understand why they insist on playing in such heat and humidity,” Ljubicic exclaims, his frustration palpable. “Athletes risk getting hurt, the public doesn`t enjoy it. Something must be done.” This isn`t just about player welfare; it`s about the integrity and quality of the sport. Who wants to watch a Grand Slam decided by who collapses first, rather than who plays the best tennis? It`s a curious irony that a sport seeking global expansion and maximizing revenue might inadvertently be undermining the very health of its primary assets – its elite athletes.

The Race for Year-End Supremacy
Beyond the US Open title, the battle for the year-end World No. 1 ranking looms large. Alcaraz holds a significant lead, but the Masters 1000 in Paris and the ATP Finals – traditionally strong hunting grounds for Sinner – offer a massive 2500 points. If Sinner performs well in New York, the race could go down to the wire, making for a thrilling conclusion to the season. Alcaraz, despite sometimes “fluctuating performances,” has developed the crucial ability to “win even those matches where certain shots don`t come off,” a testament to his maturing game, especially impressive for a 22-year-old.
The US Open promises drama, high-stakes tennis, and perhaps, a pivotal chapter in one of the sport`s most compelling modern rivalries. But as Ivan Ljubicic reminds us, beneath the spectacle lies the raw human element, constantly tested by the relentless demands of the professional circuit.
