The Spanish champion secured all six major titles with his coach's mentorship, his most recent coming at the recent US Open.
Six-time major champion Carlos Alcaraz has split with his coach Juan Carlos Ferrero in a unexpected decision.
Alcaraz, 22, has worked with his fellow Spaniard since he was a youngster, but announced on Wednesday that the duo have "mutually agreed to end their collaboration" ahead of the 2026 season.

"Our journey began this path when I was very young, and over all this time you've accompanied me on an remarkable journey, on and off the court.
"I've enjoyed every step of it immensely with you."
