Maria Sharapova hopes to name a new coach soon after confirming she has split with Thomas Hogstedt.
The world No 2 has been with the Swede since 2010 and Hogstedt helped Sharapova back to the top of her game after a long battle with shoulder problems.
Their best moment together came in 2012 when the Russian star completed her own personal Grand Slam by winning the French Open title, in doing so reclaiming the world No 1 spot.
Sharapova's form has continued this season, although she was a losing semi-finalist at the Australian Open and lost to Serena Williams in the defence of her Paris title before going out in the second round at Wimbledon to unseeded Michelle Larcher de Brito.
In a statement on her website, Sharapova said: "After almost three years of working together, Thomas Hogstedt and I decided to part ways.
"Due to personal issues, he was not able to travel in the near future and we both agreed it was the right time to move our separate ways.
"I am very thankful for all his work, and wish him much success in the future. I will be announcing my new coach in a few days. Very excited!"
