Daniil Medvedev described the three-man battle for grand slam history as "their thing, not mine" as he set his sights on denying Rafael Nadal a 21st major in Sunday's Australian Open final.

Russian Medvedev is the 6ft 6in obstacle blocking the route to history once again, just as he was at the US Open last September when he prevented Novak Djokovic becoming the first man to 21 and crushed the Serbian's hope of a first calendar sweep of the men's singles slams since Rod Laver's 1969 feat.

At the age of 25, Medvedev is 10 years Nadal's junior, and he has an awful long way to go before he is revered to the same degree as the 'Big Three' of Nadal, Djokovic and Roger Federer.

But Medvedev is asserting himself as the leader of the pack that will drive the men's game forward over the next decade, and he will be fancied by many to topple Nadal this weekend in Melbourne.

This will be his fourth slam final, after losing a marathon five-set tussle against Nadal at the 2019 US Open, being beaten ruthlessly by Djokovic in the Australian Open last year, and then storming to glory in New York.

Asked about the fact he has always faced elite opposition in his finals, Medvedev said: "They are really strong, huh? It's really tough to get into the final, and I always have them there waiting for me.

"But it's fun. When I was like eight, 10 years old I was playing against the wall and I was imagining that it's Rafa on the other side, or Roger. Novak was still not yet there, I think.

"Now I have the chance to play him [in a major final] for a second time. The first one was a close one, an epic one. I need to show my best, because that's what I took from the three finals that I had before, that you have to do better than 100 per cent in order to win. That's what I managed to do in the US Open. That's what I'm going to try to do on Sunday."

Medvedev, who beat Stefanos Tsitsipas in four sets in their semi-final on Friday, says Nadal's pursuit of the all-time men's grand slam record would not impact upon his own game.

"I'll be honest, on me it doesn't [have an effect]," Medvedev said. "It's not me going for the 21st, not me trying to break these records.

"I'm going for my second one. I'm still far from all these things. I'm just trying to focus on myself, doing my job.

"I'm not lying, I know what's happening, I know what Rafa is going for, I knew what Novak was going for. But it's kind of their thing, not mine. I'm just there to try to win the final."

It is clear Medvedev, a fiery character, has enormous respect for Nadal's ability to hold back from letting his own feisty emotions boil over.

"We know what Rafa's mentality in life is like. I don't know if I should call it this way, but he's like a perfect guy," Medvedev told a news conference.

World number two Medvedev will be attempting to become the first man in the Open Era to follow his maiden grand slam singles title with another at the next major. He said it would be a "great battle" against Nadal, and Medvedev, who predicted Djokovic would be keeping a close eye on the match, would be happy to disrupt the fairy tale narrative.

The ever-popular Nadal is coming back from a foot injury and has surpassed most expectations by sweeping through the draw, chasing his second Australian Open title but first since 2009, when he beat Federer.

"They are the three biggest players in the world: Novak, Rafa, Roger," Medvedev said. "All have done amazing, amazing records.

"Some of them have more records in total. They have all the same slams. Somebody has more Davis Cup titles, somebody has more Roland Garros, Australian Open, whatever.

"Rafa, especially what he's done at Roland Garros [winning 13 French Open titles], I really doubt somebody could ever beat this. But on the other ones, he's really strong also. I think it's going to be a debate for 20 years to come, no matter even who has the most slams, who of them was better. I want to say, they're all amazing."
