Emma Raducanu watched her US Open final win on her first night back in the UK

The 18-year-old arrived back at home in Bromley on Thursday, five days after her historic victory in New York.

Raducanu spent Friday morning doing the rounds of breakfast TV and radio, telling BBC Breakfast: “I think it’s gradually sinking in a bit more. Last night I re-watched the final and tried to relive a couple of the moments and remember how it felt.

“But it’s still such a whirlwind of an experience. I’ve loved every moment of it. It is something that is very difficult to fully comprehend.

“When I was watching it, it almost feels like that’s not me who’s playing and pulling off some of those shots. I knew exactly what was going to happen but still there’s some very tense moments and I was really proud of how I came through some moments.

“And the timeout at the end, I didn’t realise how stressful that was watching on TV.”

Raducanu has spoken of how her parents’ strict approach helped her become a grand slam champion.

Of her welcome home, the teenager said: “They just gave me a hug when I came back, nothing crazy. My mum made some really good homemade dumplings. Just some reassurance in saying they’re proud of me is enough.”

Raducanu has not yet treated herself to anything with the £1.8million prize money she won.

Both the teenager’s parents are in finance, and the told ITV’s Good Morning Britain: “I know that tennis is an extremely expensive sport so it will probably go towards that.”

Raducanu became an A list celebrity overnight, receiving a last-minute invitation to the glitzy Met Gala in New York.

She said: “I found out the night before and it was amazing. I was so grateful to get the opportunity to go. The performances were amazing. I managed to see Lewis Hamilton, which was really cool because I’m a huge motorsports fan.”

Along with a letter of congratulations from the Queen, Raducanu also spoke on the phone to Prime Minister Boris Johnson.

“It was really nice of him and he congratulated me, but we also spoke about how we both wanted to try to inspire more kids in grassroots tennis and get more young children involved, and hopefully my win can show you can live a normal life and achieve great things,” she said.

Raducanu has been inundated with praise for her achievement, with Liverpool manager Jurgen Klopp calling her “the talent of the century”.

She told Sky News: “I think that women’s tennis at the moment is extremely strong and the depth that the game has, all of the players can pretty much win every event. I’m really grateful to Mr Jurgen Klopp for his comments.”

Raducanu is now one of the world’s most marketable athletes, and is sure to be showered with offers of endorsements, but she vowed to keep her eye firmly on the ball.

“I won’t overcommit myself,” she said. “I’ll just take it as it is and the most important thing for me is still my tennis and improving and training. I won’t let any commitments get in the way of that.

“My goal now is just to keep improving and maximise my potential and what I can do. I feel like even though I won the US Open there are still many, many aspects of my game that can improve.”

Raducanu will take some time at home to rest and recover before deciding where to make her next appearance on tour, with Indian Wells next month the leading candidate.
