Grigor Dimitrov has ended one of the longest coaching partnerships of his career.
The 34-year-old Dimitrov announced he has split with his coach of eight years Dani Vallverdu.
Dimitrov announced the split on his Instagram Stories.
“Eight years! It’s been an incredible journey with you on and off the court,” Dimitrov posted. “Grateful for the lessons, the laughs and the memories we’ve shared.
“Thank you for believing in me and for pushing me to be my best. You’ll always be part of my story. Wishing you all the best in your next adventure.”
Vallverdu previously coached Andy Murray.
The announcement comes three months after Dimitrov split with co-coach coach Jaime Delgado, who also previously coached Andy Murray.
Former world No. 3 Dimitrov withdrew from the 2025 US Open as he continued recovery from a partial rupture of his pectoral muscle he suffered while leading world No. 1 Jannik Sinner 6-3, 7-5, 2-2 in the Wimbledon round of 16 in July.
The withdrawal ended Dimitrov’s remarkable run of 58 consecutive Grand Slam appearances that dates back to the 2011 Australian Open. Dimitrov held the longest streak of consecutive Slams played among active men and the fifth longest streak in Open Era history. Mutua Madrid Open tournament director and Dimitrov friend Feliciano Lopez owns the longest streak with 79 consecutive Grand Slams in a row. That streak ended in 2022.
A 2019 US Open semifinalist, Dimitrov has contested semifinals at three of the four Grand Slam tournaments, including the 2014 Wimbledon and 2017 Australian Open.
Last month, Dimitrov launched his comeback at the Rolex Paris Masters. Dimitrov defeated Giovanni Mpetshi Perricard 7-6(5), 6-1 in his opener before conceding a walkover to Daniil Medvedev in round two.
Dimitrov is currently ranked No. 44.
