Emma Raducanu has been playing the role of tour guide in London this week for her fellow sporting superstar Eileen Gu, as the British tennis No 1 announced a new four-year partnership with banking giant HSBC. US Open champion Raducanu, 19, is busy preparing for Wimbledon, where she first rose to prominence last summer before her shock triumph in Flushing Meadows. The 18-year-old double Olympic champion and part-time model Gu, meanwhile, is in town for the Tiffany exhibition at the Saatchi Gallery.

Gu shared a photo on her Instagram story of the two of them at a restaurant, before Raducanu posted a picture under some Union Jack bunting. Raducanu wrote â@eileen_gu_ takes ldddnnnâ, with Gu sharing the post and adding the caption âLondon innitâ. Itâs perhaps not surprising to see that the pair have become friends â they both have Chinese mothers, with Raducanu raised in London, England, and Gu growing up in California. They have also both achieved stunning sporting success at such young ages, which has seen them become hot properties on Instagram and endorsement favourites. Raducanuâs latest money-spinning deal was revealed on Thursday, with the tennis star to collaborate with Wimbledon sponsor HSBC â which was founded in Hong Kong â on âsports initiatives and financial opportunities for the next generationâ, according to a press release. âTo partner with HSBC is so natural for me having grown up playing in the HSBC Road to Wimbledon and having been a customer for many years,â she said in the release. âIf I wasnât a tennis player, I would definitely want to work in finance, so Iâm excited to learn more about the industry in the years to come. âWe are working on some really cool ideas and Iâm particularly looking forward to working on initiatives that help young people such as financial education, but watch this space.â While Raducanu represents Britain on the sporting stage, Gu opted to fly the flag of China, and became an international superstar with two gold medals and one silver at the Beijing 2022 Winter Olympics in February. Gu caused a stir last week by revealing that she will be part of a US bid for Salt Lake to host the 2030 or 2034 Winter Games â which drew praise and anger alike on Chinese social media platform Weibo.
