The British ace has been questioned about the amount of sponsorship deals she has signed since winning the US Open in 2021 but is now putting herself first to ensure she gets the most out of her career.

Raducanu told reporters: "I’ve learnt how to say no a bit more.

"Initially I felt really bad for, like, letting people down. I’d always want to do extra for whatever partner or magazine or whatever I’m shooting for. If they wanted to do another half day, I would do it and I’d fit it in around my schedule. I would put my practices early and then do that in the afternoon. But I think now I’ve learnt to put myself first a little bit more."

Raducanu signed deals with brands such as Porsche and Dior after her triumph at Flushing Meadows and admits that she was unprepared for the demands that came with having a high-profile away from the court.

She explained: "I’m obviously very grateful and fortunate to have had certain experiences and opportunities.

"But I wasn’t prepared for it. In my head, it was just, like, ‘OK, I wake up, I play tennis, I go to the gym and I go home, and I don’t have anything else to do,’ you know? [But] after I did well, the next few years, there was so much communication about things off the court. I would always give my 100 per cent on the court. I was always working really hard. But I just think that I wasn’t prepared as well for the other things that inevitably do take some energy out of you.

"I think now I’m a lot more structured. I’ll be like: ‘OK, I have one hour where we’re going to talk about business, and now I’m going to go train for the rest of the week.’"
