Dominic Thiem has confirmed he has been given a coronavirus vaccine and will return to action in Abu Dhabi next month with the objective of playing in the 2022 Australian Open.

The 2020 US Open champion has been out of action since suffering a wrist injury at the Mallorca Championships in June.

Thiem on Tuesday revealed he has made good progress with his recovery and will play in the World Tennis Championship, an exhibition event that will be staged from December 16-18.

The 28-year-old had stated he wanted to wait for a Novavax jab, but was urged by Austrian minister for Social Affairs, Health, Care and Consumer Protection Wolfgang Muckstein to take an alternative vaccine as his preferred choice would not be available until next year.

Thiem says he has now been vaccinated and is relishing getting back on court as he eyes a grand slam return in Melbourne in January.

"I am very happy to announce that my recovery is going well. The MRI I did today showed that my wrist injury has improved significantly," Thiem tweeted on Tuesday.

"A couple of weeks ago I started playing with soft balls and was able to switch to normal tennis balls during yesterday's practice session. My team and I strongly believe that I'll be ready to make my comeback later this year.

"I'll be returning to competition in December and will be playing the MWTC 2021 in Abu Dhabi – with the objective to return to the Tour for the 2022 Australian Open.

"Needless to say that the vaccine is needed to play both events, and in my case I have already been vaccinated. I saw recently some news about this and I had to make it very clear that I would get vaccinated. Hopefully the next time things won't be taken this far [sic] as I saw last week..."

Rafael Nadal is also set to return from injury in Abu Dhabi.

Rafael Nadal intends to make his Tour comeback next month and plans to play at the 2022 Australian Open.

The 20-time major champion has not played since a defeat to Lloyd Harris at the Citi Open in August.

The 35-year-old, who withdrew from Wimbledon and the Tokyo Olympics after losing to Novak Djokovic in the French Open semi-finals, also pulled out of the US Open due to a recurring foot injury.

Nadal has spent time training in Mallorca this month following treatment in Barcelona and said he was not sure when he would make his return to action.

Speaking at a sponsor event in Paris, Nadal said he hopes to play at the World Tennis Championship next month before a possible tilt at the first grand slam of next year, an event he has won just once back in 2009.

"My plan is to play Abu Dhabi in December and then in a tournament before Australia and then the Australian Open. That's my goal," Nadal said. "We're working hard to make it happen.

"The injury in my foot still needs to get a little better, but I'm already training almost an hour and a half a day so that's positive. Some days are better than others, but I'm starting to have a lot more positive days than negative ones.

"So, I'm on the right track. I'm training, I'm feeling better. I'm back on the court."

World number eight Casper Ruud and world number 13 Denis Shapovalov are two of the big names from the ATP Tour to have confirmed they will play in Abu Dhabi in the event that runs from December 16-18.

Women's Olympic gold medallist Belinda Bencic and surprise US Open champion Emma Raducanu have also signed up to make their tournament debuts.

The Australian Open, won this year by Novak Djokovic, is due to start on January 17.

Novak Djokovic is unwilling to commit to January's Australian Open as the defending champion awaits confirmation on travel and entry requirements amid Victoria's vaccine mandate.

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 due to 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.

Last week, Australia prime minister Scott Morrison said unvaccinated players would be allowed to contest the slam if they completed two weeks in quarantine, though Victoria premier Dan Andrews dismissed those comments, insisting athletes would not be granted access unless they received the COVID-19 vaccine.

A record nine-time Australian Open champion, world number one Djokovic remains non-committal over his looming title defence.

"Well, I'm going to decide on whether I go to Australia or not after I see the official statement from Tennis Australia," Djokovic said as he prepares for the Paris Masters – his first tournament since losing to Daniil Medvedev in September's US Open final.

"Right now, we don't have any official announcement or statement. So until that's out, I won't be talking about this anymore, because I don't want to be part of the stories about the assumptions and what-ifs.

"When official condition requirements to travel to Australia and play in Australia are out, then obviously I'll see what I personally do with that, and also the bigger group of the players, you know, because the situation is obviously different in Australia than most parts of the world."

World number two Medvedev also refused to confirm his Australian Open participation.

"I always said it, that I really like Novak's answer about this. I want to keep my medical, no matter if it's about vaccine, leg injury, head injury... I want to keep my medical private for a reason," Medvedev said.

"I feel like tennis is such a brutal sport where you're always one on one against your opponent, and any information you give him can go against you.

"If you're playing Australia, it's obvious you're vaccinated. So that's why I said I'm willing to play Australia, but I won't say if you'll see me there, but we're going to see in January."

World number one Novak Djokovic said he will return to action at the Paris Masters blessed to be a more "humble" tennis player.

The Serbian makes his first appearance since his US Open final defeat to Daniil Medvedev at the ATP 1000 tournament in the French capital.

That defeat in New York cost Djokovic the chance to become only the third man to win a singles calendar slam by winning all four majors in the same year.

Djokovic also missed the opportunity to move top of the all-time Grand Slam tournament winners list and remains joint-top alongside Roger Federer and Rafael Nadal with 20 titles.

However, the 34-year-old – whose status for the 2021 Australian Open remains unknown – was phlegmatic when he reflected on his loss to Russian world number two Medvedev.

"In a most ideal scenario, I would have won all four of them," Djokovic told a media conference. "Knowing I was so close gives me great encouragement for the future, but it also makes me feel humble about my game, about my career.

"It gives me a kind of reality check where I have to go back to the practice court and really understand what needs to be done so that I could improve.

"This was not an ordinary loss considering the circumstances. I have learned over the years to deal with losses in such way that I treat them as great opportunities for growth.

"I feel that the US Open loss in the final has arrived arguably at the worst or at the best time for me, in a way.

"I'm disappointed that I lost the match, but I feel like I was blessed to experience love from the crowd and support from the stadium that I have never experienced before in my life in New York, and actually not in many places around the world.

"That kind of energy that I received from the crowd from the moment I stepped on the court until I stepped out is a win for life."

Djokovic, who has won four of the last eight Paris Masters tournaments, claimed the prospect of ending the year as the world number one ahead of Medvedev will motivate him.

Should he do so then Djokovic would leapfrog Pete Sampras for the most year-end number one finishes in history with seven.

He will face either Italian Fabio Fognini or Hungarian Marton Fucsovics having received a bye through the first round.

"The year-end number one is on the line between Medvedev and myself, and I'm in a pretty good position," added Djokovic, who has won 85 ATP tour titles.

"That's obviously the goal for the end of the season other than trying to do well in the Davis Cup with the national team. So hopefully I can have a strong finish of the season and clinch that year-end number one.

"I’m pleased to be back. I have been training really well the past couple of weeks. And I have had plenty of success in Paris over the years, so that gives me enough reason to believe that I can do well.

"The lack of match play could be dangerous, so I have to really make sure that I start off my first match very well with a good intensity and build my form."

Novak Djokovic's participation at the Australian Open has been cast in doubt once again as Victorian premier Daniel Andrews indicated the state that hosts the event will not welcome those who are not fully vaccinated against COVID-19.

Australian minister for immigration Alex Hawke revealed last week Djokovic, who has won a record nine titles at Melbourne Park, could only take part in January's tournament if he has received both jabs.

But the 20-time grand slam winner, who has declined to reveal his vaccination status, was given hope of competing after prime minister Scott Morrison said there would be exemptions should the state of Victoria – which includes Melbourne – agree.

However, responding to those comments on Wednesday, Andrews made clear his government would not apply for any sort of dispensation as it would not be fair on the other players and spectators who are fully vaccinated.

"The federal government manages the border and to the extent that anything the federal government says on this is clear, because their position has gone 180 from what the immigration minister said," Andrews said.

"What I'm making equally clear on behalf of every vaccinated Victorian who is doing the right thing... the only fair thing to do is to be very clear with every Victorian, my government will not be applying for an exemption for any unvaccinated player."

Recent reports suggested that over a third of professional players on the ATP Tour remain unvaccinated ahead of the 2022 Australian Open, which runs for two weeks from January 17.

Andrews added: "I'm not going to ask and actually require people sitting in the grandstand, people working at the event, to be vaccinated while players aren't.

"So we're not going to be applying for an exemption, so the issue is basically resolved."

Andrews also stated the same approach will be taken when Formula One returns to Melbourne in April next year.

Speaking last week, world number one Djokovic – who beat Daniil Medvedev earlier this year to win his latest Australian Open crown – told Serbian newspaper Blic: "Things being as they are, I still don't know if I will go to Melbourne.

"I will not reveal my status whether I have been vaccinated or not, it is a private matter and an inappropriate inquiry.

"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.

"I am following the situation regarding the Australian Open... I believe there will be a lot of restrictions just like this year, but I doubt there will be too many changes."

Daniil Medvedev says it is "logical" that the age of Rafael Nadal, Roger Federer and Novak Djokovic has made it easier to play against the 'Big Three' of men's tennis.

For so long, that triumvirate has dominated the ATP Tour, with Djokovic winning three of the four grand slams on offer in 2021 – denied only a clean sweep by Medvedev at the US Open.

Nadal has struggled with a foot injury for most of the year, though, a problem that saw him miss out on Wimbledon, the Tokyo Olympics and Flushing Meadows after losing to Djokovic in the French Open semi-finals.

Federer, similarly, has missed large parts of the 2021 term after requiring a third operation on his right knee in the space of 18 months.

Medvedev accepted Djokovic had proven "he can beat everyone" in another sensational season, but – while heaping praise on a golden generation of tennis – the Russian said it is natural that time has caught up with all three.

"It would be silly to deny it…[it's] logical," he told reporters about the prospect of younger players replacing the greats at the top of the men's game.

"It is something natural. It is not something that I decide. It is evidence. They get old and now it is easier to play against them."

Medvedev only dropped one set across the entire tournament en route to securing a maiden slam at the US Open.

However, Medvedev was reticent to say the shift in power has taken place.

"I do not dare to speak of a generational change in tennis," Medvedev said.

"It is the best generation in the history of tennis.

"Nobody can come close to the results they have achieved.

"We all want to defeat that troika. And they don't want to lose either."

Medvedev then focused on his own progress, having pulled out of the Kremlin Cup citing injury problems from an early exit in Indian Wells.

"I want to win more Grand Slams," he continued. "I also want to be number one and be at the top of tennis for many years. But you can't win every tournament, it's impossible."

Australian Minister for Immigration Alex Hawke insists Novak Djokovic would need to be fully vaccinated against COVID-19 in order to enter the country and defend his Australian Open title.

The Serbian is the top-ranked player in the world and could move clear of Rafael Nadal and Roger Federer for grand slam titles if he can claim his 21st at Melbourne Park.

However, Hawke's comments regarding vaccination requirements cast doubts over Djokovic's participation, with the 34-year-old previously declining to reveal his vaccination status.

"You'll need to be double vaccinated to visit Australia," Hawke said to Australian Broadcasting Corporation radio. "That's a universal application, not just to tennis players. I mean that every visitor to Australia will need to be double vaccinated.

"I don't have a message to Novak. I have a message to everybody that wishes to visit Australia. He'll need to be double vaccinated."

With recent reports suggesting that over a third of professional players have yet to be fully vaccinated, a significant number could be denied the chance to play in the opening grand slam of 2022.

The men's ATP and women's WTA tours have attempted to encourage players with reservations to get the vaccine, and Tennis Australia explained that it was working with government authorities regarding conditions for the tournament.

"Our understanding is that the details around international visitors entering the country are yet to be decided and we hope to have more information soon," Tennis Australia said in a statement.

Australia's health minister Greg Hunt defended the ruling, explaining that the decision had been taken with the safety of the country's citizens in mind.

"The [rules] apply to everyone without fear or favour," Hunt said. "It doesn't matter whether you are number one in the world or you are anything else."

Djokovic, who withdrew from the Indian Wells Masters this month, has won nine of his majors at the Australian Open.

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."

US Open champion Emma Raducanu has split from coach Andrew Richardson and wants to partner with someone with greater WTA Tour experience. 

Richardson had coached Raducanu in her younger days at Bromley Tennis Centre and accompanied the 18-year-old for her campaign at Flushing Meadows. 

The experience proved unforgettable as the Briton, ranked 150 in the world at the time and having played in just one other major previously (Wimbledon in July), took the title after moving through qualifying and the main draw without dropping a set. 

She became the youngest grand slam finalist since Maria Sharapova won Wimbledon as a 17-year-old in 2004 and is the only qualifier in tennis history to win a major final. 

Her astonishing triumph catapulted her to 22 in the WTA rankings and Raducanu is now looking for someone to guide her through the next phase of her career. 

Speaking at a homecoming event organised by the Lawn Tennis Association, she said: "Where I was at after Wimbledon, I was ranked around 200 in the world and at the time I thought Andrew would be a great coach to trial, so we went to the States but never did I even dream of winning the US Open and having the run I did, and now I'm ranked 22 in the world, which is pretty crazy to me. 

"I feel like at this stage in my career, and playing the top players in the world, I realised I really need someone right now that has had that WTA Tour experience at the high levels, which means that I'm looking for someone who has been at that level and knows what it takes. 

"And especially right now because I'm so new to it, I really need someone to guide me who has already been through that. 

"Obviously having such an experience with your team, it's tough to have that conversation with anyone, but I think for me, it's just really what I need." 

It has been suggested Raducanu could look to partner with Darren Cahill, the renowned coach who split with Simona Halep this month. 

For now, she is considering when to make a competitive return to action, with the notable Indian Wells Open coming up. 

"I'll decide in the next few days where I'm going to go to but, wherever I play next, I'm going to make sure I'm ready. I don't want to jump into things too early," she said. 

Novak Djokovic may have missed out on completing a Grand Slam in 2021 but his "crazy" achievements across the year have received praise from Roger Federer. 

Djokovic fell at the final hurdle in his bid to secure a clean sweep of the majors, losing in straight sets to Daniil Medvedev at the US Open.

The Serbian's defeat at Flushing Meadows means Rod Laver remains the last man to claim all four majors in one year, the Australian doing so for a second time in 1969 having previously managed the feat seven years earlier. 

Neither Federer, who missed out on playing in New York due to knee surgery, nor Rafael Nadal have done so in their stellar careers, though the Swiss is certain a calendar slam is still possible.

"Will it actually happen again, that a player will win all four grand slams in their career? I think so," Federer said.

"We have seen with Rafael Nadal, Novak Djokovic and of course with me as well that this is possible.  

"It is extremely hard, of course. But I have the feeling, more than ever, that we can dominate on all kinds of ground where we have all found our own game.  

"The problem is mentally and physically it is not getting any easier for any of us. So, what Novak was able to accomplish this year has to be highly rated. It was absolute top class. It was crazy." 

Federer confirmed he would be out for "many months" when revealing he would require a third procedure on his problematic right knee in the space of 18 months.

However, the 40-year-old – who sits tied with long-time rivals Djokovic and Nadal on 20 grand slam singles titles – has suffered no setbacks in his recovery so far, putting him on course for a competitive return to the ATP Tour in the 2022 season.

"I'm feeling actually really good, considering, you know, that things are not as I hoped they would be, but I'm recovering well and the rehab is going really good, I must say," Federer said. 

"I've had no setbacks. You know, every day is a better day. I'm feeling strong and excited for what's to come."

Federer has not played since losing in straight sets to Hubert Hurkacz in the Wimbledon quarter-finals back in July.

Novak Djokovic was "playing for history" and suffered from nerves in his US Open final defeat to Daniil Medvedev, according to previous champion Dominic Thiem, who backed the 34-year-old to return "stronger than ever" in 2022.

Medvedev prevented Djokovic from becoming the first man since Rod Laver in 1969 to win all four grand slams in a single year, beating him 6-4 6-4 6-4 in Sunday's thrilling showpiece.

Djokovic was seen in tears during the third set as his hopes of adding the US Open to his run of wins at the Australian Open, French Open and Wimbledon this year slipped away.

But Thiem tipped Djokovic to bounce back from the disappointment of defeat and return in 2022 even stronger.

"One unbelievable goal slipped out of his hands yesterday," Thiem told Stats Perform.

"I expect him to be as strong as ever in 2022. I think after he won in Roland Garros, everybody was only talking about the calendar slam – first about the golden slam, and then about the calendar slam.

"He [Djokovic] was under pressure. Nobody can feel that or anything like that because of it being the calendar slam.

"I can feel it in a smaller way, probably from last year's final and from some other matches. And at some points it's just getting to you. And so, I really felt for him as well towards the end of the match.

"So, it can happen that it also makes him even stronger next year when all these talks and all this pressure is not that big anymore."

Thiem, who missed the tournament with a wrist injury that will rule him out until 2022, believes nerves were a factor in Djokovic's defeat but agreed with Medvedev's assessment of the Serbian as the greatest of all time – though he could not set him apart from Roger Federer and Rafael Nadal.

"For me, there are three GOATs in the game, and each of them has achieved something very unique," Thiem said of the trio locked on 20 major titles each.

"So it's still the same for me as it was before. The three of them are the best in the history to me.

"And I'm only super happy to be in the same era with them and to be able to compete with them. Hopefully many more times next year again."

Dominic Thiem believes Emma Raducanu's sensational US Open triumph might be the "greatest breakthrough performance of all time".

Raducanu, 18, overcame fellow teenager Leylah Fernandez 6-4 6-3 on Saturday to cement her place in history.

Her triumph meant she became the first qualifier – male or female – in tennis history to win a grand slam final.

She did not lose a set in 10 matches across qualifying and the main draw, becoming the first player since Serena Williams in 2014 to win the US Open without dropping a single set.

Raducanu – whose first grand slam appearance only came at Wimbledon in June – was ranked 150th in the world before the US Open, but her stunning win in New York has seen her break into the top 30.

Thiem, who missed the men's tournament with a wrist injury, was in awe of Raducanu's stunning run at Flushing Meadows and says he can scarcely recall a more impressive breakthrough in the sport.  

"There were some other great achievements in the past but with Emma Raducanu, starting in the qualifiers and then playing such great tennis and making this incredible path, it's definitely, maybe, the greatest breakthrough performance of all time," he exclusively told Stats Perform.

"It's an incredible journey if you look at the stats. She didn't lose one set the whole tournament. She came from qualifying and she didn't even play one tie-break. That's simply amazing and something that was probably never witnessed before.

"And also the way she plays, her technique, the way she moves, somehow she brought it up to a new level for the whole game and it was great to see.

"But as well, her opponent, it was so fun to watch her. I was excited for it, watching every single point on TV. And it was great not only for women's tennis, but for all sports in general."

Shock US Open champion Emma Raducanu has what it takes to win Wimbledon in the future, according to British great Virginia Wade.

Raducanu, 18, beat fellow debutant finalist Leylah Fernandez 6-4 6-3 on Saturday to become the first qualifier – male or female – in tennis history to win a grand slam final.

The British sensation – the youngest women's grand slam finalist since a 17-year-old Maria Sharapova took the title at Wimbledon in 2004 – did not lose a set in 10 matches across qualifying and the main draw, becoming the first player since Serena Williams in 2014 to win the US Open without dropping a single set.

The triumph also saw her become the first British woman to win a major tournament since Wade claimed the Wimbledon crown 44 years ago.

Raducanu reached the last 16 of this year's Wimbledon – her only other grand slam appearance – before pulling out of the competition due to medical reasons.

Wade, who was in attendance for the final at Arthur Ashe Stadium, believes Raducanu has all the attributes to follow in her footsteps and win British tennis' showpiece tournament during what she predicts will be a glittering career.

"I see her winning Wimbledon some time," Wade exclusively told Stats Perform. "I don't have a crystal ball, so I don't know when.

"I feel sure her time will come. She's just too good not to.

"Physically she's wonderful, she's the right height, has long legs, moves smoothly and is very quick from left to right.

"She's light on her feet, reads the ball well, her serve is terrific and her groundstrokes are solid.

"She's got balance out there and her concentration and determination are important factors as well."

Fernandez, 19, defeated top five trio Naomi Osaka, Elina Svitolina and Aryna Sabalenka along with three-time major winner Angelique Kerber on her way to Saturday's final.

And although she succumbed to a straight sets defeat, Wade believes the Canadian, along with Raducanu, will dominate the women's game for years to come.

"They're both absolutely terrific players and they enchanted everybody," she added. "Everybody was thrilled with them.

"You only get these extra special players once in a decade or once every two decades.

"In the women's game we have a really solid block of really good players. In my mind there are six to 10 players who will have to share the hardware in the next five to 10 years because they are all good. It's impossible for someone to win them all.

"Emma and Leylah will have their fair share of winning, and probably more than the others, being at the top and being feared."

Daniil Medvedev was relieved to close out his first grand slam title at the US Open after revealing he was cramping in his quest to conquer Novak Djokovic.

Medvedev blitzed world number one and 20-time major champion Djokovic 6-4 6-4 6-4 in the men's final at Flushing Meadows on Sunday.

Djokovic's bid to become just the third man and first since Rod Laver in 1969 to claim a calendar Grand Slam, and to surpass Roger Federer and Rafael Nadal for the most major men's titles, was emphatically ended by Medvedev.

Medvedev fired down 16 aces and hit 38 winners in a ruthless display on Arthur Ashe Stadium. However, the second seed conceded he was worried at the end of the third set as he tried to see off Djokovic.

Russian star Medvedev double-faulted twice in succession when his first championship point arrived and gave back one of those breaks to Djokovic, who closed to 5-4. But the former came out to serve again and again served a double on a championship point, though he had another in store and the Serb netted on the backhand.

"I definitely had it [pressure]," Medvedev – who lost to Djokovic in the 2021 Australian Open final, having gone down to Nadal in the 2019 US Open showpiece – told reporters. "I started cramping at 5-3, I think because of the pressure at 5-2 where I had match points, I didn't make it. My legs were gone after 5-3. At 5-4, left leg, I almost couldn't walk. If you really look the replay, when I walked to the towel, my leg was just going behind. I was trying not to show it. If Novak feels it, it's not good.

"Again, 40-15, that's two match points. I was like, C'mon, go for an ace, just try to make it. I had a huge double-fault. Second one was like in the middle of the net. Okay, I have one more. Just try to make a first serve. I made it and I'm really happy."

Medvedev became the first Russian man to win a grand slam since Marat Safin at the 2005 Australian Open.

The 25-year-old also became the ninth different men's champion of the last 14 years in New York, including first-time major winners Dominic Thiem, Marin Cilic, Andy Murray and Juan Martin del Potro. During the same time, the Australian Open, French Open and Wimbledon have each been claimed by four different men.

Medvedev – the second player since Ivan Lendl in 1987 to lose just one set en route to the men's US Open crown after Nadal in 2010 – is the fifth player to clinch a slam final against Djokovic.

He is also the fourth player with four or more wins over Djokovic as world number one, after Nadal (nine), Federer (five) and Murray (five).

"It definitely makes it sweeter [beating a world number one for first major trophy]," Medvedev said. "I mean, a grand slam is a grand slam. I would win it against Botic [Van de Zandschulp] in the final, probably I would be same happy.

"For the confidence and for my future career, knowing that I beat somebody who was 27-0 in a year in grand slams, I lost to him in Australia, he was going for huge history, and knowing that I managed to stop him it definitely makes it sweeter and brings me confidence for what is to come on hard courts so far, but let's see about other surfaces."

Medvedev was also asked about his celebration – the 13-time ATP Tour champion fell to the court after vanquishing Djokovic, with his eyes closed and tongue out.

It was in reference to FIFA's video game and the "dead fish" celebration.

"I like to play FIFA," he said. "I like to play PlayStation. It's called the dead fish celebration. If you know your opponent when you play FIFA, many times you're going to do this. You're going to score a goal, you're up 5-0, you do this one.

"I talked to the guys in the locker, they're young guys, super chill guys. They play FIFA. They were like, That's legendary. Everybody who I saw who plays FIFA thinks that's legendary. That's how I wanted to make it.

"Again, it's not because I want to be on the newspaper talking about FIFA celebration or whatever. I don't care. But I wanted to make it special for people to love, for my friends to love who I play FIFA with. I knew I'm going to make it. I got hurt a little bit. It's not easy to make it on hard courts. I got hurt a little bit, but I'm happy I made it legendary for myself."
