Novak Djokovic says he does not feel any different "in terms of stress" as he aims to beat Stefanos Tsitsipas in the Australian Open final and win a record-equalling 22nd men's major.
Serbia's Djokovic, 35, faces the 24-year-old Greek - who is bidding for a first Grand Slam title - on Sunday.
"I know every single Grand Slam is a golden opportunity for me to try to get another trophy," Djokovic said.
"I don't know how many more opportunities I'll have."
Tsitsipas faces a tough task against Djokovic, who has not lost in Melbourne since 2018 and has dropped just one set this tournament after a series of dominant performances.
