Angelique Kerber and Johanna Konta make coaching changes

WATCH—An update on the WTA race to Singapore:

Angelique Kerber has split with her coach, Wim Fissette, despite winning Wimbledon and returning to the Top 5 this season during their partnership.

In a statement, the German's management said that the pair were stopping right away, indicating that Fissette will not accompany Kerber to the WTA Finals next week, her final tournament of the season.

"Despite the successful co-operation since the beginning of the season, this step was necessary due to differences of opinion on the future of the alignment," said the statement.

Kerber won two Grand Slams and reached No. 1 in 2016 before falling in the rankings in 2017. She has experienced a turnaround this season, saying she is playing with less pressure.

Fissette has also had successful seasons with Sabine Lisicki, Simona Halep and Johanna Konta. He was also the hitting partner and coach of Kim Clijsters.

Coincidentally, Konta also just made a coaching change, splitting with coach Michael Joyce. She has begun a trial partnership with Dimitri Zavialoff.

Konta defeated Elise Mertensto win her opening round in Moscow in their first event together. Joyce was brought on during the offseason in 2017. That was when the Brit split from her previous coach, having finished the season on a four-match losing streak despite reaching a career-high No. 4 a few months before. She's currently ranked No. 44.

Zavialoff is the former coach of Timea Bacsinszky and Stan Wawrinka, helping both reach the Top 10.
