Tennis: Nadal admits Tokyo Olympics will be very difficult to pull off

Rafael Nadal paid tribute to Australia's response to the coronavirus pandemic and the measures taken to allow this year's Australian Open to go ahead. Several tennis stars - most notably defending men's singles champion Novak Djokovic - have spoken out about the strict quarantine protocols they have had to follow since arriving in the country. But Nadal praised the measures taken by the Australian government: "It's one of the best examples in the world about how to do things well." The world number two cast doubt on tennis events at the rescheduled Tokyo Olympics though, saying it will be tough for players to take part if they have to self-isolate for up to 15 days in Japan prior to the games.
