Six-time major champion Carlos Alcaraz has split with his coach Juan Carlos Ferrero in a shock move.
Alcaraz, 22, has worked with his fellow Spaniard since he was a teenager, but announced on Wednesday that the pair have "decided to part ways" before the 2026 season.
Neither Alcaraz nor Ferrero has given a reason for the split.
World number one Alcaraz has not yet outlined if he plans to replace Ferrero.
"Thank you for turning childhood dreams into realities," Alcaraz said in a statement.
"We started this journey when I was barely a kid, and throughout all this time you've accompanied me on an incredible journey, on and off the court.
