Novak Djokovic admits "history is hovering" over him as he takes on Casper Ruud in the French Open final on Sunday with a men's record 23rd Grand Slam title tantalisingly close.

The 36-year-old Serb can set numerous landmarks in what will be his seventh championship match at Roland Garros.

As well as breaking the 22-Slam tie he shares with Rafael Nadal, he can become both the tournament's oldest champion and the only man to win all four majors on at least three occasions.

"The only thing I can say is that I'm very focused. History is always something that's hovering over me," said Djokovic, the 2016 and 2021 winner in Paris and now the oldest finalist in 93 years.

Djokovic, playing his 34th Grand Slam final, can also return to the world number one ranking with victory over Ruud, replacing Carlos Alcaraz, the man he defeated in the semi-finals.

Victory on Sunday would place him once again halfway to an historic calendar Grand Slam, a sweep of all four majors in the same year which has only ever been achieved by two men.

Rod Laver accomplished it twice, the last coming in 1969.

Djokovic, however, refuses to contemplate such dominance, wary of how the pressure doomed his last bid to pocket all four Slams in the same year when he lost the 2021 US Open final to Daniil Medvedev.

"I'm not thinking about a calendar slam. I'm thinking really just to win another Grand Slam title here on Sunday, and I'm so close. I know it. I know the feeling," said Djokovic.

Ruud was runner-up to Rafael Nadal in the 2022 final before also losing the championship match at the US Open to Alcaraz.

The 24-year-old Norwegian has never defeated Djokovic in four meetings and has yet to win a set.

Despite Ruud's desperately poor record against Djokovic, he can point to his prowess on clay.

Since 2020, he has the most wins on the surface with 87, most finals with 12 and nine titles.

On Sunday, the world number four will attempt to make sure that all the pressure sits squarely on the shoulders of Djokovic.

"I think it's just a matter of not thinking like, I 'need' to win this match. This is a word that I try to avoid," he said.

Alexander Zverev, defeated in straight sets by Ruud in the semi-finals, believes that Djokovic might crack under the weight of expectation.

"If I would have to bet money, maybe I wouldn't bet on Casper too much. Does he have chances? Yes, he does," said Zverev after a third successive semi-final loss in Paris.

"But I think it couldn't be better for Casper. Novak is one of the best players in the world, that's for sure, but when you're on the brink of history I think that adds a little bit of pressure.

"You remember the US Open final he had with Medvedev? The pressure, you know, we are all human. Novak is human."
