World number one Novak Djokovic is unsure if he will defend his Australian Open crown in Melbourne next year due to vaccination requirements.

The state of Victoria, where the year's opening grand slam takes place at Melbourne Park, has introduced a vaccine mandate for professional athletes and across most industries amid the coronavirus pandemic.

The 2021 Australian Open went ahead, albeit in February instead of January, and without fans for most of the tournament following a snap lockdown of Melbourne due to COVID-19.

Djokovic was among the players critical of the conditions athletes endured prior to this year's Australian Open, with strict quarantine measures introduced, though the nine-time champion cast doubt over his participation.

"Things being as they are, I still don't know if I will go to Melbourne," 20-time major winner Djokovic told Blic. "I will not reveal my status whether I have been vaccinated or not, it is a private matter and an inappropriate inquiry.

"People go too far these days in taking the liberty to ask questions and judge a person. Whatever you say 'yes, no, maybe, I am thinking about it', they will take advantage."

"Of course I want to go, Australia is my most successful grand slam tournament. I want to compete. I love this sport and I am still motivated," said Djokovic, who has not played since losing in the US Open final, having withdrew from the Indian Wells Masters.

"I am following the situation regarding the Australian Open and I understand the final decision [on COVID-related restrictions] will be made in two weeks. I believe there will be a lot of restrictions just like this year, but I doubt there will be too many changes.

"My manager, who is in contact with the Australian Tennis Federation, tells me they are trying to improve the conditions for everyone, both for those who have been vaccinated and those who have not."

Victoria state premier Daniel Andrews responded to Djokovic's comments on Tuesday, saying it was unlikely unvaccinated players would be granted a visa to travel to Australia.

"I don't think an unvaccinated tennis player is going to get a visa to come into this country and if they did get a visa they'd probably have to quarantine for a couple of weeks," Andrews told reporters.

Twenty-time grand slam winner Rafael Nadal has refused to put a timeline on his comeback to competitive tennis and will only return when he is in "good condition".

Nadal has not played since early August when he lost to Lloyd Harris in the third round at the Citi Open, before withdrawing from the US Open due to a recurring foot injury.

The 35-year-old Spaniard had in June pulled out of Wimbledon and the Tokyo Olympics shortly after losing to Novak Djokovic in the French Open semi-finals, saying he was "listening to my body".

Nadal, who will not return this season, has been seen training in Mallorca after last month receiving treatment in Barcelona, offering hope of a return.

"I want to recover from this injury in good condition," Nadal told a news conference.

"I don't know when I will play again, I work a lot every day, I follow a specific plan with a marked roadmap and with very clear objectives."

The next major on the calendar is the 2022 Australian Open to be played in Melbourne in January although Nadal would not commit to participating.

"I will not say what those objectives are, because there are always things that I can't control 100 per cent, but inside my head I'm clear on what my objectives are and I trust that things will follow a positive course," he said.

"Not everything depends on me, but I am confident that my daily efforts will pay off and allow me to return soon."

Andy Murray has called for more players to get vaccinated against COVID-19 ahead of the Australian Open next year.

Unvaccinated players are expected to be allowed to compete, but are likely to have restrictions imposed on them in Melbourne.

The 34-year-old voiced his support for such restrictions, explaining that he understands why they would be put in place.

"My understanding is if you're unvaccinated you're still allowed to play, it's just the rules are going to be different," Murray said.

"You might just have to leave [for Australia] a few weeks earlier than everyone else. That's the player's choice. If the local government puts that in place then I would support that.

"It would be great if more players got vaccinated. Australia, in particular, has been very, very strict over there. The public there have had to endure a painful 18 months or whatever.

"If people are going to come into the country and potentially risk an outbreak in their community, yeah, that's understandable."

Murray was beaten in the Indian Wells third round by Alexander Zverev, who admitted he had not been vaccinated in April, on October 12 and the German declined to take a side in the debate.

"I fully respect the decisions of players that are not vaccinated," Zverev said. "I also do respect the decision that the Australian government is giving.

"I don't want to be in the middle of something which I kind of am not involved in because I don't have that issue of the two-week quarantine, all that. I don't want to go against anybody here."

Andy Murray is looking to give his body time to recover before the end of 2021 after going down to a narrow defeat against Alexander Zverev at the Indian Wells Masters.

Third seed Zverev triumphed 6-4 7-6 (7-4) in a hard-fought third-round battle with Murray on Tuesday.

Three-time grand slam winner Murray had previously defeated Adrian Mannarino and rising star Carlos Alcaraz in California.

He then ran Zverev close, with the German saying afterwards he felt Murray had produced his best performance since returning from hip surgery.

Murray agreed there were positives to take from his run, but was again frustrated not to get a statement win, having also fallen in five sets to Stefanos Tsitsipas at the US Open.

The Briton may play ATP Tour events in Antwerp and Vienna over the next fortnight but is soon eyeing a break that means he will not be putting himself forward for the Davis Cup Finals, which take place over 10 days from the end of November.

Recovering some freshness and spending time with his family are on Murray's agenda ahead of the Australian Open early in 2022.

"I've given a lot to the Davis Cup, and sometimes to my own detriment physically," Murray told BBC Sport after the loss to Zverev.

"The same thing happened last time I played Davis Cup at the end of 2019. I know there was coronavirus, but I was struggling with that really up until September time the following year.

"I also don't feel right now I would be playing, either. Obviously that would be up to [Team GB captain] Leon [Smith], but I'm not sure I deserve to play in that team.

"Right now, I'm not planning on playing the Davis Cup and with the late finish to it, and early departure to Australia, with my schedule between now and the end of the year, I am going to have to rest and take a break and give my body a chance to breathe.

"And I want to make sure in the offseason I get to spend as much time with my family as I can because I have been away from that recently and that will be case when I go to Australia as well."

On the defeat to Zverev, Murray said: "The positive for me to take from it is I had opportunities again.

"I didn't feel like I played a great match and still had chances, so that's positive. But I'm disappointed because I want to be winning these matches. I haven't in the past few months."

Both players forced six break points each and fired down eight aces apiece in an even contest.

Murray broke Zverev three times across the two sets and led in each of them, but ultimately it was the world number four who progressed to book a tie with Gael Monfils in the last 16.

It was the first time Zverev had beaten Murray in three attempts and he has now triumphed against each of the Big Four, with previous wins over Novak Djokovic, Rafael Nadal and Roger Federer to his name.

Australian Open chief Craig Tiley is confident the season-opening grand slam will be held in Melbourne next year, despite coronavirus concerns.

COVID-19 continues to wreak havoc around much of Australia, with Victoria and New South Wales both locked down due to outbreaks in the states.

The 2021 Australian Open went ahead, albeit in February instead of January, amid the coronavirus pandemic and without fans for most of the tournament following a snap lockdown of Melbourne.

Novak Djokovic was among the players critical of the conditions athletes endured prior to this year's Australian Open, with strict quarantine measures introduced.

Players, however, as set to spend two weeks in a biosecure bubble prior to the 2022 event, according to Tiley.

"There's a lot of time between now and when we get going but, at this point in time, we're planning on having a two-week bubble, where the players will be able to move freely between the hotel and the courts," Tiley said.

"They're protected, they're kept safe among themselves and safe from the community as well.

"And after those two weeks, they'll come out and be able to compete in the Australian Open in front of crowds."

Naomi Osaka's shock withdrawal from the French Open has raised questions over news conferences and their impact on mental health for athletes.

Osaka pulled out of Roland Garros on Monday, a day after tournament organisers fined the four-time grand slam champion and threatened her with more severe sanctions for refusing to attend mandatory media conferences.

The 23-year-old world number two and Japanese star had opened up about her mental health problems, revealing in a statement she has had "long bouts of depression" since claiming the 2018 US Open.

While her WTA and ATP Tour colleagues voiced their support, Osaka's stance has sparked controversy, though more importantly it has highlighted the growing issue of mental health problems in sport.

"I think it's a very important stance because it really highlights how sport has really looked at challenging issues through either the paradigm of sport or business," World Players Association executive director Brendan Schwab told Stats Perform. "Here, there is a very simple rule put in place that athletes have to attend post-match media conferences in order to promote visibility around the sport and then to promote the commercial interests of the sport. But that rule is put in place without any due diligence being done as to the risks with that on athletes or athlete health and safety.

"If we look at health and safety, we have to look at not only physical health but mental health and wellbeing. There is a very clear rule but it's going to impact athletes differently. The tournament organisers and sports bodies need to understand they have this proactive duty and to be aware of those impacts, and where their rule is going to have a harmful impact, they need to just adjust their procedures and requirements accordingly."

German great Boris Becker voiced his concerns for Osaka's future following her decision to quit the French Open in Paris.

A six-time slam winner, Becker told Eurosport: "I always believed the media was part of the job. Without the media, there is no prize money, no contracts, you don't get half the cake. I hated the media and I didn't like talking to journalists, but you had to do it.

"Now she is pulling out of the tournament altogether because she can't cope with it and that raises much bigger questions for me. If she can't cope with the media in Paris, she can't cope with the media in Wimbledon or the US Open. So I almost feel like her career is in danger due to mental health issues."

It is a view shared by many past and present tennis players – news conferences are part and parcel of the job. But are they?

"I think everyone would agree that is an important part of the job, but certainly not an essential part. The essential part of the job is performing as a player. But we cannot ask people to perform in circumstances where it's unsafe. It may be safe for some and unsafe for others," said Schwab.

"As in this case, there is an understanding that a particular player has a pre-condition or certain vulnerability, not to respond to that is inexcusable. It's certainly no defence to say it's safe for other people. That is why we need a real deep understanding of mental health.

"It's really important to see it as an occupational issue. A sporting place is not an ordinary workplace. It is a workplace which has heightened pressure. Therefore, the likelihood of there being adverse mental health impacts are greater. It's not going to affect everyone equally and sports bodies need to be smart enough to understand that fact."

Schwab added: "For Naomi's incredibly courageous stance here, there will be other players for which withdrawal is not an option and they will continue to face the workplace and pressures associated with that and therefore exacerbating the harm they're already experiencing."

The World Players Association is the leading voice of organised players in the governance of world sport. It brings together 85,000 players across professional sport through more than 100 player associations in over 60 countries.

As mental health becomes more prevalent in a professional sports environment amid the growing physical and emotional demands, Schwab said: "What our Players Associations do is they run player development and wellbeing programmes. The more sophisticated of those programmes would actually have employees and experts who are engaged by the player associations but often based in the teams or club environment, so the players know they can access them, they are proximate to the players so they can access tailored advice and support.

"Mental health is one of those things but there are many other issues that players will have to deal with. The athletic career itself is short-term and precarious, so there is constant effort being made to ensure players are developing holistically, they're pursuing education and other opportunities."

As Schwab voiced his disapproval of the "blanket rule" to post-match commitments, the Australian shed light on how the World Players Association prepares athletes for the media.

"Certainly part of our development programmes, we will provide what we call induction programmes so that the players go through what they will expect in terms of their athletic career, so they can excel as athletes and in the job," he said. "Clearly, dealing with the media is a very important part of those programmes, but you have to be really careful to ensure this isn't a 'one-size-fits-all' approach. Player associations have a common interest with sports bodies to maximise the interest in the sport and commercial viability so the players can share in their wealth, but the impact is dispiriting.

"If we look at the way players are being trained physically, physical loads are being tailored based on the individual athletic capacity of certain players. Physical health is not the only health and safety concern we have to be worried about. Players have different vulnerabilities in terms of mental health and therefore it makes absolute sense for sports bodies to tailor their commitments, so they don't unnecessarily expose more vulnerable players than others. A blanket rule, like in this case, where athletes feel vulnerable and are at risk of an adverse health consequence should not be imposed.

"I really do believe the tournament organisers, Roland Garros in particular, exacerbated that harm when they started to promote the fact that other players were comfortable to do the press conferences in order to put pressure on Naomi, and clearly that has proven to be incredibly counterproductive… if the starting point is not a recognition of their proactive duty to provide a safe workplace and that safe workplace means understanding the physical, mental and the wellbeing risks holistically and then tailoring for the particular needs of players individually, then these kind of problems will likely reoccur."

The leaders of tennis' four grand slam events have commended Naomi Osaka for opening up about her mental health problems and have vowed to put players' wellbeing first.

Osaka pulled out of the French Open on Monday, a day after organisers fined the four-time grand slam winner and threatened her with more severe sanctions for refusing to attend mandatory media conferences.

The world number two said in a statement posted on social media that she has had "long bouts of depression" since winning the US Open in 2018 and never intended for her stance to become a distraction.

Osaka also indicated that she was willing to work closely with tour officials "to discuss ways we can make things better for the players, press and fans."

Amid criticism for the way in which they have handled the matter, those in charge of the French Open, Wimbledon, US Open and Australian Open have now softened their stance.

A joint statement on Tuesday from French tennis federation president Gilles Moretton, All England Club chairman Ian Hewitt, U.S. Tennis Association president Mike McNulty and Tennis Australia president Jayne Hrdlicka read: "On behalf of the Grand Slams, we wish to offer Naomi Osaka our support and assistance in any way possible as she takes time away from the court.

"She is an exceptional athlete and we look forward to her return as soon as she deems appropriate. Mental health is a very challenging issue, which deserves our utmost attention.

"It is both complex and personal, as what affects one individual does not necessarily affect another. 

"We commend Naomi for sharing in her own words the pressures and anxieties she is feeling and we empathise with the unique pressures tennis players may face. 

"While players' wellbeing has always been a priority to the Grand Slams, our intention, together with the WTA, the ATP and the ITF, is to advance mental health and wellbeing through further actions.

"Together as a community we will continue to improve the player experience at our tournaments, including as it relates to media.

"Change should come through the lens of maintaining a fair playing field, regardless of ranking or status. Sport requires rules and regulations to ensure that no player has an unfair advantage over another.

"We intend to work alongside the players, the tours, the media and the broader tennis community to create meaningful improvements. As Grand Slams, we aim to create the stage for the players to achieve the highest accolades in our sport."

Osaka's shock withdrawal generated an outpouring of support across the tennis world and beyond, with the likes of Serena Williams, Billie Jean King and Martina Navratilova backing the 23-year-old's stance.

Gael Monfils also chipped in on Tuesday, the top-ranked French men's player pointing out that it is difficult to judge Osaka's situation from the outside.

"We need Naomi. We need her definitely to be 100 per cent," he said following his win over Albert Ramos-Vinolas.

"We need her back on the court, back on the press conference, and back happy. You know, that's what we need.

"What she's dealing with is tough for me to even judge, because I think she has massive pressure from many things.

"I think she's quite young. She's handling it quite well. Sometimes we want maybe too much from her, and then how she says maybe she can't manage it that well, so sometimes for sure she's going to make some mistakes.

"But I give her always the chance because she's a champion, she's quite young, she has a huge influence. I think she needs to take some time for herself to work on herself, feel better."

Naomi Osaka's decision to boycott mandatory media interviews at the French Open has left tennis legend Billie Jean King "torn".

Osaka revealed in the build-up to the second grand slam of the year that she would not partake in media duties, stating that "people have no regard for athletes' mental health" during news conferences.

The WTA – organisers of the women's tour – encouraged the Japanese superstar to reach out for support with her mental well-being but stressed she had a "responsibility" to her sport to honour contractual commitments.

The 23-year-old conducted an on-court interview after beating Patricia Maria Tig on Sunday but did not appear at the allotted time for her post-match media conference and was hit with a $15,000 by tournament organisers, who threatened further sanctions, including a possible suspension.

King, a 12-time grand slam singles champion, took to Twitter to outline her stance on what is proving to be a contentious issue.

"I fully admire and respect what Naomi is doing with her platform, so I am a little torn as I try to learn from both sides of the situation," wrote King, a co-founder of the WTA.

"While it's important that everyone has the right to speak their truth, I have always believed that as professional athletes we have a responsibility to make ourselves available to the media.

"In our day, without the press, nobody would have known who we are or what we thought. There is no question they helped build and grow our sport to what it is today.

"I acknowledge things are very different now with social media and everyone having an immediate ability to speak their truth.

"The media still play an important role in telling our story. There is no question that the media needs to respect certain boundaries.

"But at the end of the day it is important that we respect each other and we are in this together."

Osaka plays Ana Bogdan in round two on Wednesday.

Naomi Osaka has been fined and threatened with possible expulsion from the French Open after choosing not to take part in mandatory media interviews at the tournament.

Osaka declared her intentions in the build-up to the second grand slam of the year, stating that "people have no regard for athletes' mental health" during news conferences.

The WTA – organisers of the women's tour – encouraged the Japanese superstar to reach out for support with her mental well-being but stressed she had a "responsibility" to her sport to honour contractual commitments.

The 23-year-old conducted an on-court interview after beating Patricia Maria Tig on Sunday but did not appear at the allotted time for her post-match media conference.

Tournament organisers have fined Osaka $15,000 for breaching their code of conduct and warned she could be defaulted from the French Open – and face possible suspensions from other majors – should she continue a media blackout.

Osaka, holder of the US Open and Australian Open titles, has previously said any such fines should go towards a mental health charity.

A statement on the French Open's official website read: "Naomi Osaka announced last Wednesday on social media that she would not participate in the mandatory media interviews at Roland Garros 2021.

"Following this announcement, the Roland Garros teams asked her to reconsider her position and tried unsuccessfully to speak with her to check on her well-being, understand the specifics of her issue and what might be done to address it on site.

"Following the lack of engagement by Naomi Osaka, the Australian Open, Roland Garros, Wimbledon and the US Open jointly wrote to her to check on her well-being and offer support, underline their commitment to all athletes' well-being and suggest dialogue on the issues. She was also reminded of her obligations, the consequences of not meeting them and that rules should equally apply to all players.

"Naomi Osaka today chose not to honour her contractual media obligations. The Roland Garros referee has therefore issued her a $15,000 fine, in keeping with article III H. of the code of conduct."

The statement went on to say: "We have advised Naomi Osaka that should she continue to ignore her media obligations during the tournament, she would be exposing herself to possible further code of conduct infringement consequences.

"As might be expected, repeat violations attract tougher sanctions including default from the tournament and the trigger of a major offence investigation that could lead to more substantial fines and future grand slam suspensions.

"We want to underline that rules are in place to ensure all players are treated exactly the same, no matter their stature, beliefs or achievement.

"As a sport there is nothing more important than ensuring no player has an unfair advantage over another, which unfortunately is the case in this situation if one player refuses to dedicate time to participate in media commitments while the others all honour their commitments."

The statement was co-signed by organisers from all four grand slams.

Australian Open chief Craig Tiley is confident tennis' season-opening grand slam will take place in Melbourne next year despite suggestions the tournament may be played overseas.

The federal government in Australia is sticking to predictions that international borders will be closed until at least the middle of 2022, leaving the feasibility of hosting the Australian Open shrouded in doubt.

It has even been suggested in a recent ABC report that alternative destinations are being explored, with Dubai and Doha said to be being considered as potential venues.

But Tiley, speaking to RSN, believes the timeline on opening up borders will be altered in time for the tournament, which traditionally takes place in January.

"We're talking about two weeks of quarantine and the borders remaining closed until the middle of next year, but I'm an optimist," Tiley said.

"I think that's going to be too long. I think it's going to be brought forward because we're going to get on top of it with the vaccines and how we manage the virus.

"If we don't, we're going to be extremely challenged."

This year's tournament was blighted by logistical issues, with several players forced into quarantine after being exposed to coronavirus on chartered flights into Australia, while just days before the event was due to begin more than 500 players and officials were made to isolate after a worker at an Australian Open quarantine hotel tested positive for COVID-19.

Novak Djokovic, the men's singles champion in Melbourne, was chief among those critical of the conditions players had to endure.

"The players have been travelling around the world in a bubble so there's no place in the world anymore where there's quarantine requirements for them and so they're used to certain conditions," Tiley added.

"We [in Australia] still have this 14-day requirement but of course the positive is we don't have any community transmission of the virus."

The next generation of tennis players are not close to knocking world number one Novak Djokovic off his mantle, according to three-time grand slam winner Andy Murray.

Djokovic’s big-match experience shined through while cruising to a straight-sets win over Russia’s Daniil Medvedev to seal his ninth Australian Open win and 18th career grand slam title.

The Serbian has lifted six of the last 10 slams, with 20-time slam-winner Rafael Nadal claiming three and Dominic Thiem capturing his first major honour at the 2020 US Open.

The draw opened up for the Austrian in Flushing Meadows when Djokovic was eliminated after defaulting in the fourth round when hitting a line judge with a stray ball.

Thiem is the only first-time winner of a major in the past 24 events over a six-year period, and Murray cannot see a changing of the guard anytime soon.

"The younger guys, for me, they've not shown that they're particularly close," Murray said.

"I expected the [Australian Open] final to be closer but it's a different standing to return or to serve in a grand slam final than a quarter-final or a semi.

"When you're coming up against someone who's won 17 of them, it's pretty intimidating.

"Obviously at the US Open, Dominic Thiem did what he had to do to win the event. But if Novak hadn't put a ball through the line judge's throat, it would have been the same outcome, I think."

Preparing for his first tour event of the season, an ATP 250 tournament in Montpellier, France, Murray has kept his distance from the grand-slam scene while rehabbing a long-term hip injury.

The 33-year-old admits he didn't even watch any of the action from Melbourne Park as he aims to rebuild his fitness and return to the highest level.

"I didn't watch any because I wanted to be there myself. It was a struggle to be honest," Murray added.

"I stopped following all the tennis players on social media and stuff because I just didn't really want to see it."

Murray goes up against world number 83 Egor Gerasimov of Belarus in the round of 32 on Tuesday, after finishing as runner-up to Ukraine's Illya Marchenko in an ATP Challenger event last week.

Novak Djokovic believes he silenced his critics by triumphing at the Australian Open after finishing the tournament with a torn oblique muscle. 

Djokovic clinched a record-extending ninth Australian Open title and 18th major overall with a 7-5 6-2 6-2 thrashing of Russian fourth seed Daniil Medvedev on Sunday. 

The Serbian faced criticism before the tournament over a list of requests for players who were in quarantine due to coronavirus, while also being questioned over the severity of the oblique injury suffered during a third-round win over Taylor Fritz. 

Djokovic felt the backlash was unfair, but believes he answered in the best way possible by winning the title in Melbourne again. 

"Of course, it's not nice to hear that. I mean, it also seems unfair from some people that kind of criticise and judge without really checking before," the world number one told a news conference. 

"But as I said, it's not really the first time. I have so much experience with this because it happened so many times in my life, in my career, that I experience that. It will probably not be the last one. 

"Look, at the end of the day everyone who has the stage has the right to say what they want to say. It's a matter on my side whether I'm going to react or not, in which way I'm going to react. I didn't allow it to hinder my performance. I think winning the trophy is in a way my answer."

After taking a two-sets-to-love lead against Fritz, Djokovic suffered the oblique injury. He was forced to a decider by the American before eventually managing to advance. 

Djokovic said afterwards he had torn a muscle and may need to pull out of the tournament, although was unwilling to give too much away as the event went on. 

The 33-year-old, though, said after his win on Sunday that he had torn his abdominal oblique muscle. 

"It is a tear, a muscle tear, of the abdominal oblique muscle. I felt it right away when it happened against Fritz in the third round. That's what I said in the post-match interview. I was kind of guessing, but I felt just that it's a tear because of the snap and the way I felt after that," Djokovic said. 

"I know there's been a lot of speculation, people questioning whether I'm injured, how can I recover so quickly, it's impossible to do that. I get it. I mean, look, everyone is entitled for their own opinion, and everybody has the freedom and the right to say what they want, criticise others. I just felt like it was a bit unfair at times. But, hey, it's not the first nor the last time. 

"What we have done in the past nine, 10 days, you'll get a chance to see in detail probably at the end of this year when the documentary comes out.   

"I've been filming a lot of things that I've been doing here, but also in the previous months, six months. We're planning to take that documentary out end of this year. You will be able to see more of the routine of recovery, stuff that was going on behind the curtain."

Daniil Medvedev entered the Australian Open final in red-hot form and with a strong recent record against Novak Djokovic – yet he still fell well short.

Djokovic's record-extending ninth Australian Open title and 18th major overall came in comprehensive fashion with a 7-5 6-2 6-2 thrashing of Medvedev at the Rod Laver Arena on Sunday.

Medvedev was on a 20-match winning streak that included 12 victories over top-10 players, including Djokovic - who he had beaten in three of their previous four meetings. Still, the Russian was still dismantled.

Djokovic and Rafael Nadal have now won 10 of the past 11 grand slams. The other was Dominic Thiem's success last year at the US Open, where Djokovic stunningly defaulted in the fourth round and Nadal and Roger Federer were absent.

The 'Big Four' became the 'Big Three' following Andy Murray's injury woes, and that may now be the 'Big Two'.

Federer shares the men's grand slam record with Nadal on 20, but the last of those for the Swiss great came in 2018 and the 39-year-old has missed the past three majors.

Djokovic, 33, and Nadal, 34, have shown few signs of slowing down. With the Serbian dominating in Melbourne and the Spaniard continuing to own Roland Garros, they seem to have at least one grand slam each locked away every year.

After his loss on Sunday, Medvedev said of the trio of greats: "Nothing else to say than they are undoubtedly, I don't think anyone can argue with this, the three biggest names in tennis history. I'm talking only about results. I'm not talking off court, game. I'm talking about results. What they did in tennis is unbelievable for me.

"I'm 25 now. To win nine Australian Opens, I need to win every year until I'm 34. I mean, I believe in myself, but I don't think I'm able to do it. Same with Rafa. I mean, 13 Roland Garros... We're talking about some cyborgs of tennis in a good way. They're just unbelievable.

"When I'm out there, I'm not thinking, 'Okay, they are too strong for me.' I always want to win. I beat some of them in some big tournaments, like London [the ATP Finals] for example. I just need to be better next time in the grand slam finals against these two guys or Roger."

Thiem took his chance and landed a major at Flushing Meadows, while he has shaped as the most likely successor to Nadal in Paris, where he lost finals in 2018 and 2019. Medvedev has found his rhythm and Sunday's defeat was his second in a major decider.

Stefanos Tsitsipas, 2020 US Open runner-up Alexander Zverev, Andrey Rublev and Matteo Berrettini look like potential threats, while Canadian pair Denis Shapovalov, 21, and Felix Auger-Aliassime, 20, continue improving.

But Medvedev looked more than capable of ending Djokovic's incredible record in Melbourne before falling well short, showing potential challengers they still have a way to go if they are to finally stop the all-time greats.

Daniil Medvedev rued a below-par performance after his Australian Open final loss to Novak Djokovic.

In his second grand slam decider, Medvedev was well beaten 7-5 6-2 6-2 by Djokovic on Rod Laver Arena on Sunday, seeing his 20-match winning streak ended.

Medvedev had his chances against the world number one, but Djokovic stepped up in key moments to win a record-extending ninth Australian Open title.

The Russian fourth seed felt his performance was average in the final as he mixed 24 winners with 30 unforced errors.

"I don't like to lose matches. Doesn't matter if it's a first round or a final of a grand slam. Of course, it's just that feeling that you're closer to hold the trophy than when you lose the first round," Medvedev told a news conference.

"Talking about the match, it's tough, just when you lost to reconsider straightaway. But I feel like it's the kind of matches I won throughout this tournament that he won today.

" I was there in the first set, I was up a break in the second, but in the end I lost in three sets where I didn't play bad but I didn't play my best level. Probably he made his game that good today that I couldn't stay at my best level.

"Yeah, I obviously thought about [Andrey] Rublev and [Stefanos] Tsitsipas, both amazing top-10 players, and I won with a similar score where they were playing good, but I felt like I was better. So today was the case for Novak.

"I cannot say much better than this. He was better than me today. I could have done things for sure better today, but I didn't manage to. That's why I don't have the trophy."

Medvedev recovered from 3-0 down to draw level in the first set before being broken in the 12th game, while he gave up a break lead in the second.

The 25-year-old was unsure whether his performance was down to a bad day, or Djokovic's display.

"That's where it's tough to say because I don't know 100 per cent. I feel like I for sure could have played better. Especially looking at the matches where I played him," Medvedev said.

"At the same time there is always a question maybe he was not that good the other matches I played him because it's always day by day. You know the question is how did he manage to win here nine times out of nine? Probably all the nine times he was better than his opponent.

"I don't have an answer to this question. He definitely was good. I definitely could have done better. But even if I would have done better, doesn't mean that the score would be different.

"Today we have this score. I'm the loser; he's the winner. That's the point."

Daniil Medvedev was gracious in defeat to an inspired Novak Djokovic at the Australian Open final on Sunday.

A contest billed as a potential classic was over in one hour and 53 minutes as Djokovic claimed a ninth title in Melbourne and 18th career major.

The world number one, who lost to Medvedev at the ATP Finals last year, triumphed 7-5 6-2 6-2 to extend his record to nine victories and zero defeats in the final of this tournament and close to within two grand slams of Rafael Nadal and Roger Federer.

Medvedev was disappointed he could not prolong the contest but had nothing but praise for Djokovic on and off the court, a player he described as "a god to me".

The Russian said: "I first practiced with Novak when I was like 500 or 600 in the world in Monaco and he was already number one, he'd just won Wimbledon. I thought, 'There's no way he's gonna speak to me.' The guy was a god to me.

"I was really shy. He was talking to me like I was a friend. He's never changed, whether I'm 600 in the world or four in the world, he's always been a great sport and a great friend.

"I really wanted to make this match longer and more entertaining for you. Today was not the day."

Djokovic was similarly full of praise for Medvedev, who had been on a 20-match winning streak heading into the final.

The Serbian fully expects Medvedev to become a major winner in future, although he hopes to add a few more to his collection first.

"You're a class act, a great guy," Djokovic said. "We used to spend more time together. You're not calling me any more in the last few years! But it's nice you're thinking good things about me.

"I really like Daniil off the court, but on the court, he's definitely one of the toughest players I faced in my life. It's a matter of time before you're holding a grand slam, for sure, if you don't mind waiting a few years!"

After a difficult build-up to the tournament, in which Djokovic lobbied for an easing of certain restrictions on players forced to quarantine in hotels after arriving in Australia, he credited authorities for ensuring a smooth running of events in Melbourne.

"There are a lot mixed feelings about what happened in the last month or so, but I think in the end it was a successful tournament for everyone," he said.

"It wasn't easy, it was very challenging on many different levels, but they [Tennis Australia] should be proud of themselves for what they put together and allowing us to come to Australia.

"I'd like to thank the Rod Laver Arena. I love you each year more and more. The love affair keeps going."
