Carlos Alcaraz has declared that Emma Raducanu will be "the boss" when they team up for the revamped U.S. Open mixed doubles event later this summer. The five-time Grand Slam winner confessed that it took a bit for the Brit to respond to his "special request" to partner up.

Emma Raducanu will team up with French Open champion Carlos Alcaraz in the mixed doubles at the US Open, with a prize of $1 million (£741,000) on offer for the winners. The new doubles team – who can expect to be given a portmanteau nickname of either “Alcaranu” or “Raducaraz” – are one of several eye-catching partnerships set to make their debuts in New York in August.

Nine of the world's top-10 men and nine of the top-10 women have officially entered into the U.S. Open's revamped mixed doubles event, tournament organisers said on Tuesday, with former singles champions Carlos Alcaraz and Emma Raducanu teaming up.
