Roger Federer still has the drive to return to the ATP Tour but is yet to run and is still months away in his recovery from a third knee operation.

The 40-year-old 20-time grand slam winner missed last month's Australian Open after a knee operation in August.

Federer has not played since a quarter-final loss to Hubert Hurkacz at Wimbledon last year and previously said he would be "incredibly surprised" if he was fit to play at the event in 2022.

"It's a very important next few months ahead of me," Federer said at a sponsor's event on Wednesday. "I'll know a whole lot more in April what my body is going to be like.

"Up until now I was not able to run yet and do the heavy workload. I hope that starts in the next couple of weeks and then we'll see how my body reacts.

"For now, the drive is there. I'm really motivated to do my work and what I'm allowed to do. I'd love to do way more, but the doctors are holding me back a bit."

The eight-time Wimbledon champion elaborated on his recovery, revealing he hopes to put weight on his knee again in the coming weeks.

"I can still not run. But I'm working daily in the gym," Federer said. "I really hope that I can put weight on my knee again in two to three weeks. Then we'll see how the body reacts so we can hit the ball again in April or May."

He added: "Of course I wish that everything could go quicker. But the doctors don't want me to overdo everything."

Rafael Nadal is motivated to win more grand slams than rivals Roger Federer and Novak Djokovic come the end of the trio's careers, but he believes he will need more than 21 to achieve that.

Spaniard Nadal sealed a record 21st grand slam title on Sunday at the Australian Open, beating Daniil Medvedev 2-6 6-7 (5-7) 6-4 6-4 7-5 in a marathon five hours and 24 minutes.

It was only the second Australian Open title of Nadal's decorated career and put him out ahead of Djokovic and Federer (both 20) as the man to have won the most grand slams of all time.

Nadal worried his career was over just a matter of weeks ago as he struggled to recover from the foot injury that has affected a large part of his career.

He abandoned a stop-start 2021 season in August and missed Wimbledon, the Olympics and the US Open, leaving many to wonder if Nadal would ever be a force at the top level again.

Now, the 35-year-old is the man to beat once more, although he suspects he will need to add more major titles to his name to ensure he is ahead of his two great rivals when their careers are over.

"A short time ago I would have accepted just being able to just play tennis and not to win any more grand slams, but now I have 21," he told a media conference. 

"My way of seeing it doesn't change. I want to be the one with more grand slams at the end of the careers of the three of us, because nowadays it is the three of us. Yes, I would like that, but I am not obsessed by it and it does not frustrate me that I might not be the one. 

"Honestly, I don't think that 21 will be enough to end up being who has more grand slams, but the future will tell what will happen. Again, I feel fortunate in this life.

"All three of us have won more than we could have dreamed when we were kids. I understand the debate of who is the best, and it feeds the fans, but I don't think about it like that. As always, I try to do it my way and not focus on others.

"I follow my way and if that allows me to have options to fight in order to have more moments like the ones I've just had, it will be welcome. I will fight for it and I hope to keep having chances if my physical condition allows me."

Nadal's focus now turns to the Indian Wells Masters, which starts on March 10, with it appearing unlikely he will play in Acapulco a fortnight earlier. 

"My first priority is to try to analyse how I am after the Australian Open," he added. "I need a few days and then I will analyse things with calm and clarity. 

"For Indian Wells, I would say I have the maximum determination to go if there isn't any setbacks. For Acapulco, I would like to be there but I have to make a smart choice. The perspective has changed and I do have to take decisions according to what my body allows me."

Rafael Nadal remains adamant he is not playing the numbers game as he navigates the twilight years of his career, but a record 21st grand slam title still felt "very special" to the Spaniard.

As he put it himself, what was perhaps the most unexpected major of his career was also one of the most emotional.

"That means everything for me," said Nadal, after the 35-year-old wrestled with Daniil Medvedev for five hours and 24 minutes on Rod Laver Arena, roaring back from two sets adrift to earn a 2-6 6-7 (5-7) 6-4 6-4 7-5 epic victory.

Nadal worried his career was over just a matter of weeks ago, he said, as he struggled to recover from the foot injury that has affected a large part of his career.

He abandoned a stop-start 2021 season in August, and missed Wimbledon, the Olympics and the US Open, leaving many to wonder if Nadal would ever be a force at the top level again.

At the age of 35, he is suddenly the man to beat again, having moved ahead of Novak Djokovic and Roger Federer on the list of the most successful men's singles players in grand slam history.

They both have 20, and Nadal now has 21.

Federer, who at the age of 40 is battling to return from knee trouble, hailed Nadal as "a great champion" and "an inspiration", while Djokovic saluted an "amazing achievement".

If their social media posts came through gritted teeth, both would surely appreciate the resilience of their great Spanish rival, not just in this match but across his career. In turn, Nadal says he would have no qualms finishing behind either when their final career totals are totted up.

"I don't want to change my point of view, honestly," said Nadal, who began his post-final news conference at 02:42 on Monday morning in Melbourne.

"For me it's amazing to achieve another grand slam at this moment of my career. It just means a lot to me. Of course, I know it's a special number, 21. I know what it means. It's a big significance this title."

Nadal says what matters most is the enjoyment of the big moments, rather than whether he finishes first, second or third in the private rivalry he, Federer and Djokovic have been ducking out for years.

"Today is an unforgettable day," he said. "For the last six months, I really fought a lot to try to be back on court. There have been very, very tough moments and conversations, because you don't know if I'm going to have the chance to be back on the tour.

"I feel honoured. I feel lucky to achieve one more very special thing in my tennis career. I don't care much if I am the one or not the one or the best of history, not the best of the history.

"Honestly, today I don't care much. For me, it's about enjoying nights like today. That means everything for me."

This was Nadal's second Australian Open title, a full 13 years since he beat Federer in another five-set duel.

"It is the most unexpected, without a doubt," Nadal said. "And the most surprising I think for everyone. It has been a very emotional night. Even now I am destroyed, honestly, physically."

He said he was too tried to celebrate, his body having taken a thrashing. In December, Nadal tested positive for COVID-19, adding a further complication before heading to Melbourne.

A warm-up event title put Nadal in a positive mindset heading into the Australian Open, but how the foot would hold up remained to be seen.

He said the injury is "difficult to fix, impossible really", but for now it is manageable. At one point during his recovery he said there had been "zero success" in getting to grips with the problem, saying it was "heartbreaking" at times.

"I just want to enjoy this moment," he said, back on top of the world, "and, of course, try to keep going."

Rafael Nadal was on the brink of another Australian Open final defeat before a remarkable turnaround against Daniil Medvedev.

Trailing by two sets to love, Nadal found himself staring at three break points midway through the third set on Rod Laver Arena.

But he recovered and stepped up his game, clinching a record-breaking 21st grand slam title with a 2-6 6-7 (5-7) 6-4 6-4 7-5 victory over Medvedev in an enthralling encounter that lasted five hours and 24 minutes.

Medvedev had his chances, but the US Open champion suffered his third defeat in four major finals.

Stats Perform looks at some of the key moments.

Medvedev looked on his way to a deserved and resounding win when Nadal – who had lost four Australian Open finals previously – found himself in a 0-40 hole.

But a drop shot winner from Nadal was followed by a long Medvedev backhand, with the Russian trying a drop shot that the Spaniard returned too well on his final break point chance. It would prove a decisive hold for Nadal.

"Yeah, that was a good moment when I had the triple break point," Medvedev said afterwards. "Actually, I don't remember all of them in detail, but I remember that all of three returns I made it in. I just got a little bit tight. But, again, that's tennis. I should have done better. I should have hit a winner. I maybe would have won the match.

"Tactically nothing changed. I feel like I was playing right. But Rafa stepped up. The only thing that physically was a little bit up and down, and yeah, he was I think stronger than me physically today. Starting from the third set, there were some shots and points where I was a little bit on the back foot, let's call it like this. And Rafa takes control of these moments.

"But again, yeah, I have to work harder."

Medvedev serving at 6-2 7-6 (7-5) 4-4

The vocal and enthusiastic crowd was beginning to impact Medvedev, and Nadal's level was improving.

A long forehand at 15-15 was followed by an inexplicable overhead drop shot attempt by Medvedev that hit the net, leading to sarcastic clapping of the crowd.

Nadal clinched the break with a wonderful backhand winner down the line.

Medvedev serving at 6-2 7-6 (7-5) 4-6 2-2

Medvedev had already recovered from being a break down in the fourth set when Nadal struck again after a lengthy fifth game.

An excellent return saw Medvedev net a backhand and Nadal converted his seventh break point of the game with a backhand cross-court passing shot winner.

Medvedev had stopped Nadal's momentum in the previous game when the Spaniard was attempting to serve out the match.

But Nadal broke again when Medvedev pulled a backhand wide before sending a forehand long.

Nadal was never going to let a second chance go begging.

Medvedev put a running forehand into the net and a backhand return long before an ace from Nadal set up three championship points.

He only needed one, making a backhand volley to become the first player in the Open Era to win an Australian Open final from two sets to love down.

Daniil Medvedev revealed defeat to record-breaker Rafael Nadal in the Australian Open final had crushed his tennis dreams, accusing the Melbourne crowd of being "disrespectful" and claiming he gets rough treatment because he is Russian.

After delivering an unexpected monologue at the beginning of his post-match news conference, that Medvedev described as the "story of a young kid who dreamed about big things in tennis", the 25-year-old questioned whether he would feel wanted enough to play on beyond the age of 30.

He spoke of various highs and lows in the early years of his career, before making it clear he included his fourth grand slam final appearance on Sunday in the list of letdowns, but not purely because of the result.

"I'm talking about a few moments where the kid stopped dreaming, and today was one of them, and I'm not going to really tell why," Medvedev said.

"So from today I'm playing for myself, for my family, to provide my family, for people that trust in me; of course for all the Russians, because I feel a lot of support there.

"If there is a tournament on hardcourts in Moscow before Roland Garros or Wimbledon, I'm going to go there even if I miss Wimbledon or Roland Garros or whatever.

"The kid's stopped dreaming, the kid's going to play for himself, and that's it, that's my story, thanks for listening guys."

Despite saying he would not discuss his initial statement, he was easily persuaded to expand on his points.

Medvedev said Nadal, who came from two sets down to beat the US Open champion, had been "unreal", as the Spaniard won a 21st grand slam title, moving ahead of Roger Federer and Novak Djokovic. And Medvedev also said he had no major regrets about his own performance, although he must wonder how he failed to close this one out.

He then expanded on his gripe by confirming it was the crowd's response to him that had left him upset and disenchanted, saying almost all the support was behind Nadal.

"Before Rafa serves even in the fifth set, there would be somebody, and I would even be surprised, like one guy screaming, 'C'mon, Daniil'. A thousand people would be like, 'Tsss, tsss, tsss'. That sound. Before my serve, I didn't hear it," Medvedev said.

"It's disappointing. It's disrespectful, it's disappointing. I'm not sure after 30 years I'm going to want to play tennis.

"It depends what people around me are going to tell me, but the kid that truly was dreaming is not any more in me after today. It will be tougher to continue tennis when it's like this."

He spoke about facing the 'Big Three' – Djokovic, Federer and Nadal – during recent seasons.

"Every time I stepped on the court in these big matches, I really didn't see much people who wanted me to win," he said. "It's cumulative, but today was like the top of the mountain.

"I think nationality plays a key. I can definitely see when you are playing somebody from the other country, they would go for them and not for the Russian or something like this."

Roger Federer and Novak Djokovic each paid tribute to Rafael Nadal after he passed the pair with his 21st grand slam title at the Australian Open.

Nadal set a new men's singles benchmark, breaking a three-way tie with Federer and Djokovic on 20 triumphs, as he battled back against Daniil Medvedev.

The Spaniard, whose career had appeared to be in some doubt last year due to injury, fought for over five hours to recover from two sets down in Sunday's epic final.

Federer, through injury, and Djokovic, deported amid coronavirus controversy, were both absent in Melbourne, although they have previously let slip respective opportunities to move to 21 titles.

Both therefore recognised the scale of Nadal's achievement as they took to social media.

"What a match! To my friend and great rival @rafaelnadal, heartfelt congratulations on becoming the first man to win 21 grand slam singles titles," Federer wrote on his Instagram story.

"A few months ago we were joking about both being on crutches. Amazing. Never underestimate a great champion.

"Your incredible work ethic, dedication and fighting spirit are an inspiration to me and countless others around the world.

"I am proud to share this era with you and honoured to play a role in pushing you to achieve more, as you have done for me for the past 18 years.

"I am sure you have more achievements ahead but for now enjoy this one!"

Djokovic, posting for the first time since the tournament started in his absence, said on Twitter: "There has been some outstanding tennis played at this year's #AusOpen and the finals were exceptional.

"Congratulations to @ashbarty for an amazing performance in front of her home crowd and to Danielle Collins for an incredible tournament.

"Congratulations to @RafaelNadal for 21st GS. Amazing achievement. Always impressive fighting spirit that prevailed another time. Enhorabuena.

"@Medwed33 gave it his all out there and played with the passion and determination we have come to expect from him."

Rafael Nadal made history by clinching a record-breaking 21st grand slam title with an extraordinary win in the Australian Open final.

The Spaniard became the first man to win 21 majors, breaking his tie with Roger Federer and Novak Djokovic.

Nadal edged Daniil Medvedev 2-6 6-7 (5-7) 6-4 6-4 7-5 in an incredible final that lasted nearly five and a half hours on Rod Laver Arena.

We take a look at each of Nadal's grand slam successes.

2005 French Open
Nadal's maiden major was largely unsurprising. Then 18, Nadal carried a 17-match winning streak to Roland Garros. Ranked fifth in the world after starting the year outside the top 50, Nadal beat Federer in the semi-finals before getting past Mariano Puerta in the decider. He became the first man to win the tournament on debut since Mats Wilander in 1982.

2006 French Open
That would be the start of an almost unstoppable run in Paris. Lleyton Hewitt and a young Djokovic were unable to halt his run in 2006 before he again overcame Federer, this time in the final, after dropping the first set. It was the Swiss great's first loss in a grand slam decider.

2007 French Open
Federer's win over Nadal in the final in Hamburg heading into the French Open gave the Swiss hope after ending the Spaniard's 81-match winning streak on clay. But after beating Hewitt, Carlos Moya and Djokovic on his way to the decider, Nadal again proved too good for Federer in four sets.

2008 French Open
Nadal made it four in a row in 2008 in ruthless fashion. He lost just 25 games on his way to the semis before beating Djokovic. Federer again stood between him and the title, and the Spaniard handed his great rival a 6-1 6-3 6-0 thrashing.

2008 Wimbledon
The next meeting between the greats would prove far closer, far more entertaining and land Nadal his first grand slam title away from Roland Garros. After an epic lasting almost five hours, Nadal edged Federer 9-7 in the fifth set on Centre Court to win the Wimbledon final in near darkness.

2009 Australian Open
Having risen to world number one for the first time in his career in August of the previous year, Nadal celebrated the top ranking by winning his first hard-court major. After a comfortable run to the last four, he edged Fernando Verdasco in an epic semi-final that lasted five hours, 14 minutes. Another four-plus hours and five sets were needed to get past Federer in the decider.

2010 French Open
Nadal suffered a first ever loss at Roland Garros the year prior, going down to Robin Soderling in the fourth round. But he reclaimed the title in 2010, beating Soderling in straight sets in the final. He did not drop a set on his way to the crown.

2010 Wimbledon
It would be a memorable 2010 for Nadal, who would win three majors in a single year for the only time in his career so far. His biggest test at the All England Club came from Philipp Petzschner in a five-setter in the third round before wins over Soderling, Andy Murray and Tomas Berdych from the quarter-finals onwards.

2010 US Open
Nadal had never been beyond the semi-finals at Flushing Meadows before his first success in New York in 2010. It was a comfortable run before a four-set victory over Djokovic in the final completed his career Grand Slam.

2011 French Open
Djokovic was too good for Nadal in the Rome final before the French Open, but the Serbian fell to Federer in the semi-finals in Paris. Nadal survived a surprise five-set battle against John Isner in the first round before again beating Federer in the decider.

2012 French Open
Nadal had lost three consecutive major finals – all to Djokovic – before he turned that around at Roland Garros. After a comfortable run to the decider, he needed four sets to get past the Serbian for his record seventh French Open crown.

2013 French Open
Nadal and Djokovic met in a Paris epic the following year, this time in the semi-finals. Nadal edged a classic encounter 9-7 in the fifth before cruising past countryman David Ferrer in the decider.

2013 US Open
Djokovic would get his chance on his preferred surface in New York later that year, but Nadal proved too strong in four sets in the decider. Nadal dropped just two sets on his way to the title.

2014 French Open
Djokovic had again beaten Nadal in the Rome final, but again was unable to stop the Spaniard in Paris. Nadal was untroubled on his way to the decider before recovering from a set down in the final to again beat Djokovic. The 14th grand slam of his career saw him draw level with Pete Sampras on the all-time list.

2017 French Open
After going two years without a grand slam title, Nadal ended his 'drought' in Paris in 2017, claiming 'La Decima'. He did so without dropping a set, rushing past Dominic Thiem and Stan Wawrinka in his final two matches. Nadal became the first man to win a single grand slam 10 times – and he remains the only one to manage that feat.

2017 US Open
More success would follow in New York in what was arguably one of the easiest runs to a major crown of Nadal's career. The highest ranked player Nadal faced was world number 28 Juan Martin del Potro in the semis before cruising past Kevin Anderson in the decider.

2018 French Open
Nadal was at it again in Paris the following year. He lost a set to Diego Schwartzman in the quarter-finals but was otherwise relentless on his way to an 11th Roland Garros crown.

2019 French Open
Nadal was developing a new rivalry at the French Open, but it was not one to stop his success. He was again ruthless on his way to the final and for the second year in a row was too good for Thiem in the final.

2019 US Open
His run in New York was again comfortable, at least until he reached the final. Medvedev put up a huge fight in the decider, which eventually went Nadal's way after almost five hours on Arthur Ashe Stadium, as he closed to within one of Federer's 20 grand slams.

2020 French Open
Another year, another French Open title for Nadal. There was again no stopping the Spaniard as he romped through without losing a set, including demolishing Djokovic in the final.

2022 Australian Open
Nadal became the first man to win 21 grand slam titles with the unlikeliest of major crowns. Just months earlier, he had doubts over his career due to a foot injury. After reaching the final, a five-set quarter-final win over Denis Shapovalov his biggest test, Nadal produced an extraordinary comeback. After nearly five and a half hours, he came from two sets to love down against Medvedev to win the decider. He became the second man in the Open Era to win every grand slam at least twice, and was the first in the same period to come from two sets to love down and win an Australian Open final.

Rafael Nadal said winning a record 21st grand slam felt "just amazing" as he staged a mesmerising comeback to beat Daniil Medvedev in the Australian Open final.

The 35-year-old Spaniard won 2-6 6-7 (5-7) 6-4 6-4 7-5 in five hours and 24 minutes on Rod Laver Arena, snatching victory in a match that looked Medvedev's for the taking after two sets.

In the process, Nadal went past great rivals Roger Federer and Novak Djokovic on the all-time list of men's singles grand slam winners, just months after a foot injury left him with doubts over his future in tennis.

For Medvedev this was a second successive Australian Open final defeat, having lost to Djokovic 12 months ago, and his frustration was apparent over his failure to close out the match from two sets in front.

This was Nadal's second Australian Open title and first since 2009, when he beat Federer in another five-set tussle. At the end of this match, as Nadal celebrated, the great Laver himself was captured on television footage taking a photograph of the scene.

It was 01:32 on Monday morning in Melbourne when Nadal got his hands on the trophy, and as he addressed the crowd, he began: "Good evening everybody. Well, good morning at least."

Nadal had sympathy for Medvedev, describing the Russian as "an amazing champion". Reflecting on his own disappointments in Melbourne, where he has lost four finals, Nadal said: "I don't have any doubt you'll have this trophy a couple of times in your career because you're amazing."

Roared on by thousands of witnesses to history, Nadal told Medvedev: "It has been one of the most emotional matches of my tennis career, and to share this court with you is just an honour."

There were no tears from Nadal. He was briefly stumped for words to recognise his achievement, saying: "I even don't know what to say, guys.

"For me, it's just amazing. One month and a half ago I didn't know if I would be able to be back on the tour playing tennis again, and today I'm in front of you having this trophy with me.

"You really don't know how much I've fought to be here. Thank you so much for the love and the support. Without a doubt I am having probably one of the most emotional moments in my tennis career."

Nadal lost a five hours and 53 minutes epic against Djokovic in the 2012 Australian Open final. That remains the longest grand slam final in history, but this pushed it close.

The champion said the support he was shown in Melbourne would "stay in my heart for the rest of my life", before pointing again to his battle to get fit after the foot problem that forced him to abandon his 2021 season in August.

"One month and a half ago, I would have said maybe there is a chance that's going to be my last Australian Open," Nadal said. "But now that's plenty of energy to keep going, so thank you very much.

"I really can't explain the feelings I have right now, but I'm going to try my best to keep coming next year."

A humdinger of a final saw Medvedev force a two-set lead, only for Nadal to dramatically level the match, the 35-year-old rolling back the years.

Nadal broke early in the decider to lead 3-2 and then withstood fierce pressure from Medvedev in the next game.

It was astonishing that the Spaniard was outmanoeuvring a man 10 years his junior, and a player who beat Djokovic in straight sets in last year's US Open final.

At 5-4, Nadal had a service game to cross the winning line. Federer missed a chance to reach 21 slams when he could not take two championship points against Novak Djokovic in the 2019 Wimbledon final, and this was a similar opportunity for Nadal.

At 30-15, he served a double fault, and Medvedev pounced on his chance, winning the next point after a fizzing forehand and smash, and the next when Nadal netted. The decider was back on serve, but Nadal was not finished, engineering three break points in the next game and jumping on the third of those, Medvedev hoisting a forehand long.

This time Nadal was not to be denied. When Medvedev could not scoop back a backhand volley, the title was Nadal's, and the broadest of smiles crossed his face.

Medvedev said defeat was "tough to take", but he added: "I want to congratulate Rafa because what he did today, I was amazed.

"I tried just to play tennis, but after the match I asked him, 'Are you tired?'.

"It was insane. I think the level was very high. You raised your level after two sets for the 21st grand slam. I thought he was going to get tried, and maybe you did just a little bit, but you're an amazing champion."

Looking at the race between Nadal, Djokovic and Federer to finish with the most slams, Medvedev said: "I think you guys have a good rivalry still. It's not over yet, but congrats."

Both men thanked tournament director Craig Tiley, who was close to the centre of the pre-tournament storm that saw Djokovic deported from Australia.

And Medvedev spared a thought for wife Daria, watching from home.

"Usually there's my wife in the [players'] box," he said, "but I think probably the TV's broken right now."

Already shaping as the unlikeliest grand slam success of his illustrious career, Rafael Nadal ensured it was just that after an extraordinary Australian Open final.

And what a time to deliver it, clinching a record-breaking 21st major title by beating Daniil Medvedev, breaking his tie with Roger Federer and Novak Djokovic for the most grand slams won by a man.

Nadal himself admitted reaching the final in Melbourne was unexpected, having ended his 2021 in August and doubted his career due to a persistent foot injury.

That injury is not going away, making the success even more remarkable. After five hours and 24 minutes on Rod Laver Arena, history was made as Nadal secured a 2-6 6-7 (5-7) 6-4 6-4 7-5 victory.

From two sets to love down against a man 10 years younger, wrapping up at 01:11 local time (14:11 GMT).

Nadal had only won the Australian Open once before, in 2009. Now, he is the only champion to have ever come from two sets to love down to win in an Australian Open final in the Open Era.

Not only was Nadal two sets to love down, he faced 0-40 in the sixth game of the third set. He was also staring down an in-form opponent as Medvedev aimed to become the first man to follow up his maiden major title with another grand slam at his next event. But, spurred on by a vocal and enthusiastic Rod Laver Arena crowd, Nadal found a way. He found another level, as he has throughout his career. In fairness, Medvedev took his game up a level, too, at least until some madness in the ninth game of the third set.

That concentration lapse had cost him one set, and Medvedev was unable to deal with an increasingly excited – and sometimes disrespectful – crowd in the fourth, as well as a surging Nadal.

As Sunday ticked into Monday with the deciding set underway, Nadal broke the Medvedev serve with a forehand winner down the line in the fifth game. Even the best get nervous, though, and he relinquished that advantage when serving for the title. Yet like a typical champion, Nadal responded instantly, breaking again before serving it out to love.

In sets one and two, Nadal had 21 winners and 36 unforced errors, turning that into 48 and 32 respectively in the final three.

For just the third time in his illustrious career, Nadal had completed a comeback from two sets to love down at a grand slam. And he has now won every grand slam at least twice, becoming just the second man in the Open Era to manage that, alongside Djokovic.

Such a moment had seemed unlikely just months ago, when Nadal and his team had doubts over whether he would ever return to the ATP Tour due to his foot injury.

Nadal says those doubts remain, but his start to 2022 suggests he is, as ever, a contender as long as he remains on the court. However unlikely, even if looking impossible, Nadal is still capable of the absurd.

Rafael Nadal made history in stunning fashion as he came from two sets down to beat Daniil Medvedev in the men's Australian Open final, sealing a record 21st grand slam title.

All the talk before the tournament had been about Novak Djokovic and whether the world number one would be able to compete to achieve the same feat, but it was Nadal who secured the historic victory at Rod Laver Arena, beating Medvedev 2-6 6-7 (5-7) 6-4 6-4 7-5 in a marathon five hours and 24 minutes.

It is only the second Australian Open title of Nadal's decorated career but puts him out ahead of Djokovic and Roger Federer (both 20) as the man to have won the most grand slams of all time.

He had looked down and out at times in the third set but showed typical determination to get better as the match went on, while Medvedev appeared to visibly tire as he saw his lead disappear into the night sky in Melbourne.

The first set began with Medvedev asking questions of Nadal, although initially the 35-year-old had answers with some classic forehand winners.

However, the unforced errors from the Spaniard began to pile up and he was broken to love in the fifth game. From there, Medvedev dominated the remainder of the opening set, breaking again and taking it 6-2.

It did not bode well for Nadal, who had won only three of his 10 prior major finals in which the opener had gone to his opponent.

The number six seed was struggling on his first serve, getting just 54 per cent in – his next lowest in a first set in this tournament had been 66 per cent in the second round win against Yannick Hanfmann.

Nadal showed some resilience, though, and hit a sensational winner at the end of a 40-shot rally in the fourth game of the second set, in which he ultimately broke Medvedev for the first time, only to be broken back to 4-3 as those serving struggles continued.

A back-and-forth affair saw four breaks of serve and the set ended with a tie-break, which Medvedev clinched with a backhand winner down the line to leave Nadal looking down the barrel of a defeat.

However, Nadal was not going to go down without a fight and showed some of his trademark grit in the third to stay with Medvedev, who was, if anything, playing even better than in the first two sets. Nadal had to save break points in the sixth game to eventually hold serve, before breaking in the ninth and serving out to somehow get back to within a set.

The drama did not stop in the fourth as two holds of serve were followed by three straight breaks to put Nadal 3-2 ahead. Both men were forced to save multiple break points thereafter, but Nadal successfully held serve to take it 6-4 and force a decider.

Medvedev looked to be wilting and was hanging on at the start of the fifth, before some superb Nadal winners earned a break in the fifth game.

The Russian made his opponent work hard for his victory and dramatically broke back to level when Nadal was serving for the championship, only for the veteran to break straight back before finally sealing the win and his place in the history books with a backhand volley that Medvedev could not return.

DATA SLAM: No Melbourne misery for Nadal

Nadal also becomes the second man in the Open Era – and only fourth in history – to win each grand slam at least twice, after Djokovic, Roy Emerson and Rod Laver.

Despite still boasting an impressive overall record in grand slam finals at 20-8 going into this match, Nadal was 1-4 in Australian Open finals. He looked sure to make that 1-5 after the first two sets but showed remarkable fortitude to turn things around.

This was Medvedev's second Australian Open final defeat having lost to Djokovic last year, and his second grand slam final defeat to Nadal after losing to him at the 2019 US Open.

Danielle Collins was in optimistic mood despite losing to Ash Barty in straight sets in Saturday's Australian Open final at Melbourne Park.

Barty was made to work for it by unlikely finalist Collins and had to come from 5-1 down in the second set to prevail 6-3 7-6 (7-2) on Rod Laver Arena.

Collins had raced to within one game of taking the second set, only for Barty to rally back with a quite sensational fightback that ended with tie-break success to secure the trophy.

At a media conference following the final, Collins said she was happy with her efforts against Barty and declared it a "fun battle".

"Not the result that I wanted obviously tonight, but I gave it my best effort," the American told reporters. "I did everything that I could.

"I was pushed to the max, and I gave myself a chance there in the end. Unfortunately, it didn't go my way, but I did everything I could, and that's all you can do at the end of the day.

"It was a great event for me. [I] accomplished some new things, learned a lot of new things. I certainly have some areas to improve, which is a good thing. Yeah, [I] played against a great competitor tonight, and it was a fun battle."

Barty won in front of a passionate home crowd, and Collins explained where in particular she had struggled against her.

"I think she started to push me back in the court a little bit more," Collins added. "I was having some issues really being able to fully rotate on some of my shots to be able to get my shots to where I needed them to be.

"It was really unfortunate, but I did everything I could, tried to push through it. Fell short. She definitely came up with some great shots in some of those big moments, especially with her serving and pushing me back in the court."

The 28-year-old – who hit the same number of unforced errors as Barty (22), but only 17 winners to the Australian's 30 – also had further words of gratitude for her mentor Marty Schneider, whom she also thanked along with her boyfriend in her post-match comments on court.

"We were joking about some tournaments that he had attended with me," she added. "25K in Orlando where I did not have the best performance, and thinking about the way that I'm playing now versus then, it seems like a lifetime ago, but it really wasn't that long ago.

"Other situations that I was in playing some of those smaller tournaments and facing challenges and bumps in the road and how I used to go about things and think about things, how clueless I was sometimes and how much I have learned and grown from those moments.

"Now we can kind of look back and laugh, but during those moments we had some tough conversations. Marty was always on call for all of those.

"I think we've shared some incredible memories over the years, but especially this week to see all of those baby steps come together now and being on the biggest stage in the world, it's just been so special."

Nick Kyrgios declared he and Thanasi Kokkinakis created "the best atmosphere this tournament's ever seen" as they powered to Australian Open doubles final glory.

But within minutes of the duo sealing their 7-5 6-4 win over fellow Australians Max Purcell and Matt Ebden, Purcell questioned whether the raucous crowds might in fact be a turn-off for tennis fans around the world.

After a victory that Kyrgios ranked as the highlight of his career and Kokkinakis labelled "f****** nuts", the wildcard pair were singing their own praises almost as loudly as the Rod Laver Arena had been roaring them on to victory.

Kyrgios, who will never need to hire a hype man, led the cheerleading, before announcing he would not be playing the French Open and ruling out a doubles reunion with Kokkinakis at Wimbledon. They could pair up again at the US Open, however, and potentially for the ATP Finals at the end of the year.

"The dedication I showed all week and from my team, I'm super proud of myself," Kyrgios said. "I could have not really cared too much after I lost [in singles] to [Daniil] Medvedev, but doing it with 'Kokk' is insane and this ranks one for me.

"I feel like a completely different person. I'm just happy. I've gone about it the right way.

"This is a memory we're never going to forget. We're going to grow old and always remember the time we rolled off the couch and won the Aus Open, honestly. It's crazy. I've won some titles in singles, but this one ranks top for some reason."

Kyrgios and Kokkinakis became the first Australian pair to carry off this title since Mark Woodforde and Todd Woodbridge in 1997.

The great Laver himself endorsed the new champions, sending a message of congratulations on Twitter, suggesting their appeal goes far beyond the young generation.

"I would say we've created probably the best atmosphere this tournament's ever seen, to be brutally honest with you," Kyrgios said.

He claimed that verdict had the support of Robert Barty, the father of women's singles champion Ash Barty.

"Ash's father came to us and said the crowd was the best he's ever seen," said 26-year-old Kyrgios. "Obviously Ash is a hell of a player, but I think the ratings speak for themselves.

"People watch my matches. Everywhere I play around the world, the stadiums are full for that reason. There's a reason why the ratings are the way they are and people are glued to the TV when we play. It speaks for itself really."

Kokkinakis, 25, won a singles title in Adelaide ahead of the Australian Open, and is fighting back from injuries that have stifled his progress in the game.

"Nick, I love you brother," Kokkinakis said. "I can honestly say we did not expect to even come close to this.

"It's been a rough couple of years for me personally, but what a month we've had. Coming into the Aussie Open I was already happy and this is a crazy cherry on top.

"Adelaide was number one for me, but this has trumped it. To be a grand slam champion with my boy. We've known each other since we were eight or nine years old and have done some serious things together, had some serious experiences, but this is incredible, we didn't expect this at all."

The crowds at Melbourne Park for Kyrgios and Kokkinakis have been noisy to the point of rowdy at times, with Kyrgios being described as "an absolute k***" by Michael Venus after the New Zealander and German Tim Putz lost to the Special Ks in the quarter-finals. Venus felt the atmosphere was like "a circus" and accused the Australians of stoking it beyond the point of acceptability.

Beaten finalist Purcell said he and Ebden were given a relatively easy ride, and thanked the Australian public for coming out to show their support.

But after an exuberant spectator was asked to leave the stadium late in the final, Purcell also said: "They seem like the naughtiest crowd I've ever played in front of. Even Thanasi and Nick were getting a little angry out there.

"There's a line where you don't want to cross. You don't want people to be thrown out, so if people are doing that they're obviously not doing the right thing and respecting the players.

"I think it was great for ticket sales here, but I'm not sure how it was taken overseas. If you were watching some of Nick and Thanasi's matches earlier in the week, and you were overseas, maybe you get turned off tennis a little bit."

Ash Barty said she focused on enjoying herself to avoid getting hampered by the pressure and expectation of delivering an Australian Open title.

The 25-year-old ended Australia's 44-year wait for a singles champion in Melbourne by beating Danielle Collins 6-3 7-6 (7-2) on Saturday.

World number one Barty claimed her third grand slam title, landing the trophy without dropping a set.

All the talk at the tournament focused on Barty ending Australia's drought, but the reigning Wimbledon champion said her ability to just enjoy herself was key.

"I think the expectation was that I would always come out and give my best, and that's all I've ever done," she told a news conference.

"I have been close before, but I think now that we've been able to achieve this, I think you guys don't need to talk about it anymore.

"You were the ones who added fuel to the fire, because for us it was just the same processes and the same enjoyment, regardless of where we're playing in the world, what round it is. That has no impact on how much I enjoy my tennis and go out there or how much I try and compete.

"I think it's being able to really simplify that and then just come out and enjoy it. I mean, this fortnight, seven times I got to walk out onto a beautiful court with incredible fans and try and do the best I can do, and that's all I could ask of myself.

"Now to be able to have this part of my dream kind of achieved is amazing, and I think I have to really understand that that came from the processes that we put in with my team and the people that are around me, because without them, I wouldn't be half the person that I am."

Barty came from 5-1 down in the second set to overcome Collins, sealing her victory with a forehand cross-court passing winner.

After a successful fortnight, Barty screamed in delight to celebrate her win.

"It was a little bit surreal. I think I didn't quite know what to do or what to feel, and I think just being able to let out a little bit of emotion, which is a little bit unusual for me, and I think being able to celebrate with everyone who was there in the crowd, the energy was incredible tonight," she said.

"I think being able to understand how much work my team and I have done behind the scenes and over the last few years, to get to this point to be able to have this opportunity was really special.

"I think it just kind of all came out at once, and yeah, it was a really, really special moment."

Ash Barty can still get better but she will not win the US Open unless a change that is out of her hands is made, according to coach Craig Tyzzer.

Barty became the first local in 44 years to win the Australian Open, beating Danielle Collins 6-3 7-6 (7-2) in the final on Saturday.

The 25-year-old dealt with the pressure and expectation in Melbourne to win her third grand slam title.

But Tyzzer said there was still growth left in Barty, who came from 5-1 down in the second set against Collins.

"There's still areas we continue to work on still, she's got to get better at. I'm not going to tell what you they are because that's giving away a few too many secrets. But there's still room for improvement," he told a news conference.

"I think what she's done really well is just she's enjoyed it. She's been really composed and enjoyed playing. Like tonight, we knew what the challenges were going to be, like Danielle can just blow you off the court at times. So she was looking forward to that challenge, 'Okay, how do I figure out how to beat this girl who can just hit you into the corners and hurt you every time you drop it short?'

"I think for her that's the best part. She's enjoying playing, enjoying the challenges. There's still areas we'll work on with her game. I probably don't have to do too much with her serve now. It seems to be working really well.

"But, yeah, you're always looking for areas to get better."

Barty is the second active women's player to have won a grand slam on all three surfaces, joining Serena Williams.

But Barty's chances of completing a career Grand Slam by winning the US Open rely on something out of her control – changing the balls.

"The US Open really needs to change the ball for the girls, the fact they still use a different ball for guys and girls. It's a terrible ball for someone like Ash," Tyzzer said.

"Even in Cincinnati when they use the US Open ball outside she could actually get some loft out of the court, but the ball itself is so light. It was the only tournament last year and really for two years where she uses a gut racquet, but I had to change her to a poly just to get any sort of control of the ball.

"If they keep that ball the same, no one like Ash will win that tournament. So I think you see the result at the US Open, it was two players who, you go, 'Wow, that was, two different players won that?' There's no surprise when the ball is like it is. And I don't know the reason why. It's the only tournament that has separate balls for the guys and girls. So if they don't change the balls, she won't win the US Open."

Nick Kyrgios and Thanaki Kokkinakis completed their Melbourne mission as they were crowned Australian Open doubles champions on Rod Laver Arena.

The Special Ks partnership, who have drawn huge crowds and fresh interest to doubles, sealed the title with a 7-5 6-4 win over fellow Australians Max Purcell and Matthew Ebden.

It was approaching midnight on a special day for Australian tennis when Kyrgios and Kokkinakis got over the line, following women's singles queen Ash Barty onto the roll call of this year's champions.

With one break of serve in each set, Kyrgios and Kokkinakis held firm behind their own games as the singles specialists showcased their precocious skills on the doubles court.

Kyrgios served for the win in style, firing two aces in a row before Kokkinakis put away a volley on match point.

The new champions forced the only break of the first set in the 11th game when Ebden volleyed into the net off the return of serve from Kokkinakis, who was then the chief aggressor as he and Kyrgios secured a break in the seventh game of the second set.

Kyrgios has never been beyond the quarter-finals of a singles slam, reaching that stage at Wimbledon as a teenager in 2014 before doing likewise at the 2015 Australian Open.

His redoubtable talent has not been backed up by the trophies many expected him to win, and he will have turned 27 by the time the next major, the French Open, begins in late May.

Together with Kokkinakis, whose own promising career has been blighted by injuries, Kyrgios has thrived this fortnight. And although the prize money in doubles pales against the singles rewards on offer, a first taste of grand slam glory could be a major career spark for this pair.

They were the wildest of wildcards, with Kyrgios criticised by Michael Venus, a New Zealander left in his wake in the quarter-finals, for his showboating style and geeing up of the crowd.

"It felt like a circus out there and not really a tennis match," complained Venus, speaking to New Zealand channel 1News. Any doubles partnership featuring the combustible Kyrgios is likely to be an acquired taste.

This time, though, it felt like a party, with Ebden saying he was "really, really impressed" by Kyrgios and Kokkinakis, and Purcell said it was "hell of fun to watch you guys play".

Australia Day was on Wednesday, but Saturday felt like an extended celebration.
