Former US Open champion Emma Raducanu lost in the opening round at the Ostrava Open on Tuesday. The teenager went down 7-5, 6-4 against fifth seed Daria Kasatkina.It was Raducanu's first match since retiring from her semifinal showdown against Jelena Ostapenko at the Korea Open last month. As expected, Twitter users had strong reactions to the loss, with some lambasting the Brit for her attitude on the court.One fan opined that the young tennis star doesn't care about her tennis career and should instead focus on becoming a social media influencer."Emma Raducanu doesn't care at all about a tennis career. She could better become a TikTok star or influencer. Then she can become more famous. It's clear that she has never aspired to a prof career. She acts as the biggest Diva of WTA but is no star at all. NEXT," the fan wrote.zuurtje@zuurtje3@TomYoungSJ Emma Raducanu doenst care at all about a tennis carreer.
