The Spanish champion claimed each of his six Grand Slam titles under Juan Carlos Ferrero's mentorship, his most recent coming at this year's US Open.
Six-times major champion Carlos Alcaraz has ended his partnership with his coach Juan Carlos Ferrero in a unexpected decision.
Alcaraz, 22, has worked with his fellow Spaniard since he was a teenager, but stated on Wednesday that the pair have "mutually agreed to end their collaboration" before the 2026 season.
Neither Alcaraz nor Ferrero has provided a explanation for the break.
World number one Alcaraz has yet to outlined if he plans to find a successor for Ferrero.
"I am grateful for transforming childhood dreams into realities," Alcaraz remarked in a statement.
"Our journey began this path when I was very young, and throughout all this time you've accompanied me on an extraordinary journey, on and off the court.
"I've enjoyed every step of it so much with you."
Ferrero, 45, is a former top-ranked player. He developed Alcaraz's potential at his training facility near Murcia before leading him to each of his six major championship titles.
This sudden split marks the end of a trophy-laden player-coach relationship that defined the rise of one of tennis's biggest names.
