“It’s awesome to see the depth of Australian tennis. I always knew Demon [de Minaur] was going to be carrying the flag, he’s got another 10 to 12 years – I could see him playing until he’s 40,” Kyrgios said.

“Now it’s more open, and I think that where Australian tennis is … we’re all capable of making a run at a grand slam.”

“As athletes, injuries come and go, [and] I think it’s made me a stronger person.”
