Nadal and Djokovic have been given byes into the last four, meaning they could pocket tennis’ biggest prize cheque for just two days' work. The winner of the Saudi Arabia exhibition will take home £4.6million ($6million) - almost double the £2.7m Alcaraz earned for winning Wimbledon this summer.

Some of the world’s top male tennis players will be in action at the Six Kings Slam, a new exhibition event in Saudi Arabia. The sextet is headlined by Rafael Nadal, playing one of his final tournaments as he prepares to bow out of the sport after the Davis Cup finals on home soil at the end of November.
