US Open champion Emma Raducanu is set to announce Torben Beltz as her new coach.
The German, 44, worked with Angelique Kerber when she won the Australian Open and the US Open in 2016.
They reunited for this season but Kerber announced on Monday they would not be working together in 2022.
The Telegraph first covered the story after unearthing an image of Beltz with the 18-year-old and her agent Chris Helliar in a coffee house in Orpington.
The photograph was posted on a Raducanu Instagram fan site on 20 October - the week in which the British player is known to have been conducting some trials at nearby Bromley Tennis Centre.
