Emma Raducanu has split from Coach Torben Beltz after only five months.
The 19-year-old US Open champion confirmed Beltz as her coach in November but believes a “new training model” is needed.
The LTA’s head of women’s coaching Iain Bates will work with Raducanu in Madrid this week.
“I want to thank Torben for his coaching, professionalism and dedication over the last half a year,” said the world number 11.
German Beltz, 45, previously coached former world number one Angelique Kerber when she won the Australian Open and US Open titles in 2016.
His successor will be British number one Raducanu’s fourth coach in a year.
