Raducanu splits with coach

British number one Emma Raducanu has split with the coach who guided her to a first major title at the US Open. Andrew Richardson was hired for the summer tournaments in the United States, which ended with the 18-year-old's improbable victory in New York.

Raducanu had entered the tournament as a qualifier, and the world number 150. At this stage of my career I really need someone that has had that WTA Tour experience at that high level, he explained.

'Especially right now as I'm so new to it, I think I really need someone just to guide me who has already been through that themselves. Never did I even dream of winning the US Open and now I'm ranked 22 in the world, which is pretty crazy to me.'
