Novak Djokovic and Rafael Nadal will renew their long-standing rivalry in an Australian Open final where both can create new records.
Djokovic is aiming for a record seventh men's Melbourne title, while Nadal can become the first man in the Open era to win all the Grand Slams at least twice.
Sunday's match will be an ATP record-extending 53rd meeting between them.
"It is the biggest rivalry we've seen in tennis history," Australian former Wimbledon champion Pat Cash said.
The top two seeds meet at Melbourne Park for the first time since their epic five-set final in 2012, which Djokovic won with almost six hours on the clock.
