Former US Open champion Emma Raducanu is working with a new coach after swapping mentors with reigning Olympic champion Belinda Bencic.
The British No.1 has started working with German coach Sebastian Sachs, whose former pupils include world No.1 Victoria Azarenka. Raducanu is currently in Dubai and is due to take on Ons Jabeur at the Mubadala World Tennis Championship exhibition event on Friday.
Sachs, aged 30, has previously been working with Olympic champion Belinda Bencic - who has announced she is now working with Raducanu's old coach Dmitry Tursunov. The Russian had been working with the British star on a trial basis before the US Open.
