Naomi Osaka has announced her split from coach Sascha Bajin, just weeks after winning her second successive Grand Slam title.
The 21-year-old was victorious in the Australian Open last month, to add to the US Open title she won in September last year.
Osaka is also currently No 1 in the WTA rankings, but she wrote on Twitter: "Hey everyone, I will no longer be working together with Sascha. I thank him for his work and wish him all the best in the future."

Bajin responded shortly after, writing: "I wish you nothing but the best as well. What a ride that was. Thank you for letting me be part of this."
