Australian Open confident on Nadal, uncertain on Djokovic

Roger Federer, the other men's player with 20 Grand Slam titles, and Serena Williams, who has won 23 Grand Slam titles, have already ruled themselves out of the tournament as they continue their recoveries from injury.

Australian Open chief Craig Tiley is confident Rafa Nadal will be at Melbourne Park for next month's Grand Slam despite testing positive for Covid-19, but he is still uncertain whether Novak Djokovic will be playing.
