Emma Raducanu says she is determined to wrest back control of her “natural” tennis style, with the British No 1 eager not to be bound by the diktats of a single coach.

“I want to come back to my natural way of playing. That takes time to relearn because that’s something that has been coached out of me a little bit,” Raducanu told BBC Sport. “I have had a lot of people telling me what to do, how to play, and it hasn’t necessarily fit. I don’t necessarily want to have one coach in the role because anyone I bring in is straight away going to be scrutinised – even if it’s a trial.
