Juan Carlos Ferrero, coach of Carlos Alcaraz, has lauded the burgeoning rivalry between his protégé and Wimbledon 2025 champion Jannik Sinner, emphasizing its positive impact on both players and the sport. Speaking in early 2024, Ferrero described the relationship between Alcaraz and Sinner as “super healthy” and mutually beneficial, noting, “Carlos sees the things that Jannik does well and they will feed off each other’s level”. This dynamic, he suggested, drives Alcaraz to elevate his game, particularly after Sinner’s 4-6, 6-4, 6-4, 6-4 victory over Alcaraz in the Wimbledon final on July 13, 2025, which ended Alcaraz’s 24-match grass-court win streak and marked Sinner’s first Wimbledon title.
Ferrero’s comments underscore the competitive yet respectful bond between the two, who have faced off 13 times since 2021, with Alcaraz leading 8-5. Their rivalry, dubbed “Sincaraz,” has produced classics, including the 2025 French Open final, where Alcaraz rallied from two sets down to win, and the Wimbledon rematch, where Sinner’s baseline dominance and clutch serving secured his fourth Grand Slam. Ferrero’s acknowledgment of their synergy aligns with Alcaraz’s own sentiments post-Wimbledon, where he praised Sinner’s “unbelievable” performance and expressed gratitude for their rivalry, saying, “It makes me improve every day”.[](https://www.atptour.com/en/news/alcaraz-sinner-wimbledon-2025-final-sunday)
Sinner’s coach, Darren Cahill, echoed this sentiment, revealing that Sinner watches more of Alcaraz’s matches than anyone else’s, “fascinated with the improvements coming in his game” and pushing his team to ensure he keeps pace. Cahill highlighted the significance of Sinner’s Wimbledon win, noting it was crucial not only as a Grand Slam triumph but also for overcoming a five-match losing streak against Alcaraz, including the painful French Open loss where Sinner squandered three championship points. Ferrero’s and Cahill’s insights reveal how both players’ relentless pursuit of excellence fuels their rivalry, with Alcaraz’s flair and Sinner’s steely precision pushing each to new heights.[](https://www.tennis365.com/tennis-news/jannik-sinner-coach-wimbledon-final-win-carlos-alcaraz)
As the tennis world looks to the Canadian Open and US Open, Ferrero’s praise of the “Sincaraz” dynamic signals an era-defining duel, with both players—Alcaraz with five Majors, Sinner with four—poised to dominate for years. Their mutual respect and competitive fire, as Ferrero notes, not only elevates their games but also fills the void left by the Big Three, captivating fans globally.
