Naomi Osaka, Novak Djokovic and Rafael Nadal said Sunday they remain keen to compete in the delayed Tokyo Olympics, and would be guided by what the health experts tell them. Organisers are still adamant the Olympics can be held safely even if the coronavirus is not under control by the time the flame is lit on July 23. 

Three-time Grand Slam champion Osaka dmitted being worried by a recent poll that found 80 percent of the Japanese public were opposed to Tokyo hosting the event this year because of the pandemic. Large parts of Japan are currently under a state of emergency to tackle a spike in coronavirus cases, with borders closed to almost all foreigners. "My concern would be the general safety of everyone else because you're opening the country," Osaka said. "Everyone is flying in from different places. I would just want the public to feel safe."
