Former Grand Slam finalist Karolina Pliskova has already decided on another coach. She will work with Tomas Krupa next year, fellow Czech Barbora Strycova has said.

Strycova, who is currently coached by Krupa, is furious. Krupa has worked with Strycova for two seasons, and is the former coach of Tomas Berdych.

According to Strycova, Pliskova arranged the switch following the US Open. The move angered her Fed Cup teammate.

"Our relationship is zero. We do not go for coffee. We no longer have to use the word 'friend,'” Strycova was quoted by *Idnes.cz* as saying in Linz. "When she told me she was interested in my trainer, her manager, Mr. [Michal] Hrdlička, was already with him. It was done behind my back…And then I learned on the phone that it was over.”

On *Facebook*, Strycova gave more details.

“My coach texted me and called me that he cannot keep working with me because he accepted the offer. I was very sad,” Strycova wrote. “Especially because of the way I learned it. I did not understand the way I got into this from one hour to the next and I was sad that my coach did not sit down with me to talk about it."

Right after the US Open, Pliskova split with her coach, David Kotyza, who had previously worked with Caroline Wozniacki and was the longtime coach of Petra Kvitova.

Strycova said she would still play Fed Cup with Pliskova on the team.

During the WTA Finals in Singapore, Pliskova will work with former player Rennae Stubbs, who is a TV commentator.
