Carlos Alcaraz’s stunning rise to the top of men’s tennis has long been defined by stability, patience, and a rare coach–player bond with former World No. 1 Juan Carlos Ferrero. That image cracked this week after explosive reports emerged detailing the behind-the-scenes breakdown of the partnership, with growing focus on Alcaraz’s inner circle, particularly his family, and a contract dispute that ultimately led to Ferrero’s exit.
The Foundation of Carlos Alcaraz and Juan Carlos Ferrero’s Long-Term Coaching Partnership
Alcaraz joined Juan Carlos Ferrero’s academy in 2018 at age 15, with Ferrero taking a hands-on role in his development through Futures and Challengers. Alcaraz broke through in 2021 with his first ATP title, a US Open quarterfinal run, and the Next Gen ATP Finals crown, then made history in 2022 by winning the US Open and becoming the youngest World No. 1, as Ferrero earned Coach of the Year honors.
Their partnership later produced Wimbledon in 2023 and the French Open in 2024, resulting in a total of six Grand Slam titles, eight Masters 1000 wins, and an extended time at World No. 1.
On Wednesday, Dec. 17, 2025, Alcaraz stunned the tennis world by announcing the end of his partnership with Ferrero on social media.
“Juanki and I have decided to end our time together as coach and player. Thank you for turning childhood dreams into realities. We’ve managed to reach the top, and I feel that if our sports paths had to part ways, it had to be from up there. From the place we always worked toward and always aspired to reach. Thank you for everything, Juanki!” Alcaraz wrote.

Ferrero soon followed with his own message, expressing gratitude and regret. “Saying goodbye is never easy. We have worked hard, grown together, and shared unforgettable moments. Thank you, Carlos, for the trust. I wish you all the best, both professionally and personally. I wish I could have continued. I am convinced that good memories and good people always find a way to cross paths again,” Ferrero wrote.
How Did Contract Talks and Inner-Circle Influence Lead to Ferrero’s Exit?
Despite the tone of mutual respect, reports out of Spain painted a far more complex picture. The split, according to RNE Deportes, was handled with extreme discretion and originated just two days earlier during negotiations over Ferrero’s contract.
Tennis specialist Javier de Diego revealed the crux of the issue on Spanish radio. “The rupture was produced two days ago; it is motivated by a lack of contractual agreement, and not by disagreements regarding the methodology or scheduling of the usual training work, neither physical nor technical,” de Diego reported.
He added bluntly, “We could say that the relationship is broken due to failing to reach an agreement in the negotiation of the new contract for Juan Carlos Ferrero as Carlitos Alcaraz’s coach.”
De Diego further clarified the timeline and immediate consequences. “A contract was being negotiated two days ago, when the rupture occurred, which in the end has been definitive. It was communicated this morning by the World No. 1. Samuel Lopez, until now Carlitos’ second coach, becomes the sole coach of the Murcian, whose main objective for the next season is the first Grand Slam of the year, the Australian Open.”
The most controversial element emerged when Kiko Navarro, Alcaraz’s first coach, weighed in on RNE Deportes. Navarro openly questioned whether the decision originated from Alcaraz himself, hinting strongly at the influence of his environment, which has fueled speculation about the role of Alcaraz’s father and inner circle.
“I don’t think Carlitos made the decision,” Navarro said earlier, before expanding in detail. “It was more from the environment than from the player; Carlitos is very protective of his coaches. He was with me, and I know he was with Juan Carlos, but there comes a moment when due to reasons not related to him or sports, they have made this decision.”

“Juan Carlos has done a spectacular job; I worked with him for two years, and there is little to blame him for. The people who made the decision, which is not Carlitos, will have their reasons which I don’t know now.”
Navarro also voiced support for Samuel López as head coach while hinting that another high-profile figure could yet join the setup, stating that “there may be a second person with a higher profile.”
