Rafael Nadal is hoping to meet old rival Roger Federer in the Australian Open final by beating in-form Grigor Dimitrov in their semi-final on Friday.
Spaniard Nadal, 30, has not reached a major final since winning his 14th Grand Slam at the 2014 French Open.
Federer, 35, is going for a record 18th major title after an epic semi-final win over fellow Swiss Stan Wawrinka.
"I have to play my best because Grigor is playing with high confidence," said ninth seed Nadal.
The pair meet at the Rod Laver Arena in Melbourne about 08:30 GMT on Friday.
