Daniil Medvedev and Rafael Nadal have expressed their sadness and disappointment at Novak Djokovic’s absence from the US Open. But Nadal says the show will always go on with or without the sport’s biggest stars. ‘I repeat what I said plenty of times: the sport in some ways is bigger than any player,’ Nadal said. ‘In a personal way I feel sorry for him that he’s not able to travel here. But on the other hand … (it’s his choice).’
