Novak Djokovic insists Carlos Alcaraz will be the “favourite” for Olympic gold on Sunday in the latest instalment of tennis’s generational power grab. At 37, Djokovic would be the oldest Olympic tennis singles champion since the sport returned to the Games at Seoul in 1988. 

At 21, Alcaraz would be the youngest of all time. A win for the Serb would be his first gold medal at the fifth attempt and represent a significant upgrade on the bronze he won at Beijing in 2008. Victory would also allow Djokovic to become only the fifth player to complete the Golden Slam of all four majors plus an Olympic title.
