Former Wimbledon semi-finalist Grigor Dimitrov has announced that he has parted company with coach Roger Rasheed after a poor run of form.
The 11th seed lost in the third round of this year's tournament to Richard Gasquet, while he exited the French Open in the first round earlier this season.
The 24-year-old wrote on Twitter: "After much thought I have decided to end my working relationship with Roger. I want to thank him for all his hard work and support over the past couple of years. We had many accomplishments together and I wish him all the best going forward."
Dimitrov has yet to win a title this year.
