Meanwhile, John Millman, who Federer beat in five sets at the Australian Open in January, raised the prospect of no more tennis taking place this year.
“We’re going to have to be pretty unified in terms of our recovery process before the tour can resume,” Millman told AAP.
“Maybe the tournament location has got the COVID-19 situation under wraps and then manage to contain it, but if someone’s flying in from South America, say, and their country hasn’t got a hold of it, then the tournament can’t (go ahead).
“You can’t have the tournament going when only certain players can get there. I think that’s where the problems lie.
