Seven-time Australian Open winner Novak Djokovic has had his say on who he believes may be favourites to win this year’s tournament.

The Serb has admitted that he may be one of the favourites with Roger Federer and Rafael Nadal, but also believes three rising stars may cause a shock and compete for the title.

Djokovic currently has 16 Grand Slam titles to his name and helped Serbia win the ATP Cup this week. However, he is acutely aware of new dangers that may inhibit his ability to earn a 17th.

Nadal has been in impressive form lately as well as he helped Spain reach the final of the ATP Cup before their loss to Serbia - and will be attempting to win his second Australian Open.

As for Federer, he has won Down Under six times so far, so he'll be looking to add another to his haul later this month.

However, Djokovic believes that Dominic Thiem, Stefanos Tsitsipas and Daniil Medvedev will also be challenging in Melbourne in the first Grand Slam of the season.

Tsitsipas, who is Greek, has flourished in the past two years, and managed to win the ATP Finals in London last year.

Medvedev is currently without a major title, but did threaten to dethrone Nadal when he reached the US Open final. An excellent 2019 for the Russian, who reached six tour finals consecutively in his breakout year.

Thiem is currently ranked fifth in the world and has made the final of the French Open in the past two years.

"I think it’s really open, like all the slams. I don’t think there are really clear favourites," stated Djokovic, as per The Metro.

"You obviously have Federer, Nadal, myself because of the experience and the rankings and because of everything we get named the top three favourites.

"But then you have Medvedev, Tsitsipas, Thiem that are really showing some amazing tennis.

"So, everybody keeps on talking about NextGen player winning a Slam. It seems like it’s getting closer. Hopefully not this year. We’ll see.

"They showed that they matured on the big stage, that they can challenge the best players in the world and win against them."
