Defending champion Novak Djokovic has been handed top billing by tournament organisers on day nine of the Australian Open.

Djokovic will get maximum time to recover from Sunday's five-hour marathon win over Stanislas Wawrinka ahead of a quarter-final clash with Tomas Berdych.

The top seed plays Berdych at 8.30am UK time in the Rod Laver Arena, with David Ferrer facing Nicolas Almagro in the day session to open up the last eight of the men's draw.

Agnieszka Radwanska gets day nine underway with a match against Li Na, with Maria Sharapova rounding off the afternoon session against compatriot Ekaterina Makarova.
