Very few things in tennis are predictable. But one thing you can always predict is Karolina Pliskova splitting with a coach. This time, Pliskova announced that she has split with Daniel Vallverdu.

Pliskova has made deep runs in grand slams but is yet to win a grand slam. 2020 was a disappointing year for Pliskova. Her best grand slam result came at the Australian Open, where she made the third round. 

Prior to Vallverdu, Pliskova worked with former Wimbledon champion Conchita Martinez.
