Emma Raducanu describes Naomi Osaka as "pure speed", while the Japanese star said earlier this year that the British player has "a royal air around her".

It should happen at their first tournament of 2026, the United Cup team event in Australia.
Raducanu and Osaka both achieved huge success at a young age, and finding a way back to Grand Slam-winning level has not been easy for either player.
