The Spanish champion won all six major titles under his coach's tutelage, his most recent coming at the recent US Open.
Six-time Grand Slam winner Carlos Alcaraz has ended his partnership with his coach Juan Carlos Ferrero in a shock move.
The 22-year-old Spaniard, has been teamed with his fellow Spaniard since he was a teenager, but stated on Wednesday that the pair have "decided to end their collaboration" before the upcoming season.
No explanation has been offered by Alcaraz or Ferrero has stated a reason for the split.
World number one Alcaraz has yet to indicated if he plans to find a successor for Ferrero.
"I am grateful for turning youthful ambitions into realities," Alcaraz remarked in a statement.
"Our journey began this journey when I was barely a kid, and throughout all this time you've accompanied me on an incredible journey, both on and off the court.
"It has been a pleasure to experience every step of it immensely with you."
The 45-year-old Ferrero, is a former world number one. He nurtured Alcaraz's abilities at his academy near Murcia before guiding him to each of his six major championship titles.
