Daniil Medvedev says he knows he will have to be at his absolute best to wrestle the Australian Open title from the grasp of Novak Djokovic.
Djokovic recently issued a warning to the next generation players, telling them they will have to earn their spot at the top of tennis as he will not give up his position easily.
The pair will meet in the Australian Open final on Sunday, and Medvedev says he is up for the challenge.
"When Novak says he won't hand anything over to anyone, I believe him," Medvedev said.
"To beat him, you have to be at your best for 4-5 hours, physically and mentally.
"I don't take his words as something negative, I appreciate him as a player and as a person.
"When Novak is in the zone, he doesn't miss - down the line, cross-court, forehand, backhand.
"I am good that way also, that is why we had some unbelievable matches. Later, when I see the highlights, I am like "wow".
Medvedev has played just one Grand Slam final before, losing to Rafael Nadal at the US Open.
By contrast, Djokovic has 17 major titles to his name, with eight of them coming in Melbourne.
"I think Novak is the favourite because the previous eight times he came to the final, he won the title.
"I am a challenger. I like to play against him, he is one of the greatest ever and we always have physically and mentally tough battles.
"Of course there is going to be pressure for both of us when you are playing finals of a Slam. Broader picture though - I have nothing to lose."
