Britain's Emma Raducanu and Spain's Carlos Alcaraz are among the pairings planning to play in the new-look US Open mixed doubles event.

Alcaraz and Raducanu follow each other on Instagram and the Spaniard was “caught” several times liking the WTA star’s posts and even congratulating her on some of her wins.

Men’s world No1 and defending singles champion Jannik Sinner will play alongside women’s No9 Emma Navarro, while women’s No1 Aryna Sabalenka is paired with Grigor Dimitrov. Novak Djokovic will partner compatriot Olga Danilovic and Iga Swiatek is poised to team up with Casper Ruud.
