World number one Novak Djokovic has split with coach Goran Ivanisevic.
Former Wimbledon champion Ivanisevic became Djokovic's main coach in March 2022, having worked with him alongside long-time mentor Marian Vajda for several years.
Serb Djokovic won four of his joint-record 24 Grand Slam titles under Ivanisevic.
"Goran and I decided to stop working together a few days ago," Djokovic said on Instagram.
"Our on-court chemistry had its ups and downs, but our friendship was always rock solid."
Djokovic lost in the semi-finals of the Australian Open in January, suffered a third-round defeat by world number 123 Luka Nardi at Indian Wells this month, then withdrew from the ongoing Miami Open, citing a need to balance his "private and professional schedule".
