Emma Raducanu confirmed Torben Beltz as her coach in NovemberEmma 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.
"He has a huge heart and I have enjoyed our strong chemistry during the time together.
"I feel the best direction for my development is to transition to a new training model with the LTA supporting in the interim."
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 Raducanu's fourth coach in a year.
Nigel Sears was replaced by Andrew Richardson after last year's Wimbledon, but Richardson's contract was not renewed despite Raducanu's success in New York.
