New Delhi:  Former U.S. Open champion Emma Raducanu has explained the reason behind the high turnover of coaches saying that she "keeps provoking and asking questions to coaches and challenging their thinking".

In June, the 20-year-old ended her coaching stint with Sebastian Sachs, marking her fifth coaching change within two years. She has not yet announced her new coach.

"I ask my coaches a lot of questions. On certain occasions, they haven't been able to keep up with the questions I've asked and maybe that's why it ended," Raducanu told BBC Radio 4's Today programme.
