Raducanu replied: 'You're the best best', before sharing the post on her own Instagram profile. She had previously shown off her new hairstyle in a series of images, in which she also posed with a mystery man.
Carlos Alcaraz and Emma Raducanu have appeared on a joint post on social media after the Spaniard’s relationship was reportedly confirmed.
Alcaraz, 22, climbed back to the top of the men’s ranking last weekend after winning the US Open at Flushing Meadows.
In the final, the Spaniard dispatched rival and defending champion Jannik Sinner in four sets, winning 6-2, 3-6, 6-1, 6-4.
Over the last few months, there have been rumours that Alcaraz and British star Raducanu’s relationship may be more than just a tennis partnership.
