Former World No.1 one Karolina Pliskova has appointed Naomi Osaka's former coach Sascha Bajin as her new coach for the 2021 season.
Pliskova split with coach Daniel Vallverdu earlier this month after her 2020 season came to an end.

The 28-year-old posted a photo with Bajin and fitness coach Azuz Simcich on Twitter on Friday with the caption "Team Pliskova 2021".
German coach Bajin led Osaka to back-to-back Grand Slam titles at the US Open in 2018 and the Australian Open the next year.
He has also previously worked with 23-times Grand Slam winner Serena Williams.
Pliskova lifted her only title of the year at Brisbane in January and was knocked out in the second round of both the US Open and French Open Grand Slams.
Pliskova announcement ahead of Aus Open
Pliskova’s announcement comes ahead of the Australian Open set to take place early next year, but there is uncertainty surrounding quarantining regulations ahead of the Grand Slam.
Victorian Sports Minister Martin Pakula conceded that the year's first grand slam would "most likely" be delayed - probably by a week or two.
However, it's the state's uncompromising 14-day quarantine lockdown that has proved a major bone of contention in the tennis world.
As things currently stand, players arriving from overseas would have to quarantine at a hotel for 14 days, before being able to train and properly prepare for the tournament.
Discussions are ongoing to possibly shorten that period to 10 days and to allow players to at least train while in quarantine.
