Rafael Nadal's loss to Frances Tiafoe opened up a host of possibilities including a first-time world number one and maiden grand slam winner as the top three's domination of men's singles continues to weaken.

World number three Nadal bowed out in the fourth round to 22nd seed Tiafoe 6-4 4-6 6-4 6-3 on Monday, while third seed Alcaraz triumphed over Marin Cilic 6-4 3-6 6-4 4-6 6-3 in a match that went to almost 2:30am local time.

Cilic was the last remaining male player with a grand slam title to his name, meaning this year's US Open will bring a new major champion.

There may also be a first-time world number one too, with Alcaraz guaranteed to claim the top rank if he wins the US Open title.

Fifth seed Casper Ruud will rise to world number one if he lifts the US Open crown at Flushing Meadows on September 11 too.

If both fall short of the final, Nadal will reclaim the top ranking from 2021 US Open champion Daniil Medvedev, who lost in the fourth round to Nick Kyrgios.

Alcaraz could also scale the rankings summit should he reach the final, assuming Ruud misses out.

Frances Tiafoe is dreaming big after upsetting Rafael Nadal in the US Open fourth round on Monday to open up the men's singles draw.

The 22nd-seeded American stunned the 22-time grand slam champion, winning 6-4 4-6 6-4 6-3 in three hours and 34 minutes.

The victory meant Tiafoe reached the US Open quarter-finals for the first time, having fallen in the fourth round in the past three years. It also equaled his best-ever major return, having made the 2019 Australian Open quarters as well.

It also opens up the men's singles draw for a potential new grand slam winner, with Marin Cilic – who is due to play third seed Carlos Alcaraz on Monday evening – the last remaining major champion.

"Everyone is looking at it I'm sure," Tiafoe told reporters about the draw. "Everyone looks at it. Here we go, right? So am I. I'm just taking it day by day.

"Slams, crazy things can happen. Especially here in New York, so it's going to be a fun ride come Wednesday."

Tiafoe will take on ninth seed Andrey Rublev on Wednesday in the last eight, where he will hope to re-produce the "unbelievable" form he displayed against Nadal.

"I'm beyond happy, almost in tears, I can't believe it," Tiafoe said in his on-court interview. "I played unbelievable tennis today. I really don't know what happened."

During his press conference, he added: "It was definitely one hell of a performance… I just came out there and I just believed I could do it.

"It helps I played him a couple times. Haven't played him in some years [not since 2019]. I'm a different person now, different player."

Tiafoe had never beaten Nadal before, nor had he taken a set off the Spanish world number three. The victory was Tiafoe's third against a top-five opponent.

"For a while there, I was like, geez, you see all these young guys get Rafa, Fed [Roger Federer], Novak [Djokovic], am I ever going to be able to say I beat one of them?" he said.

"Today I was like, no, I'm going to do that. Now it's something to tell the kids, the grandkids, I beat Rafa."

Tiafoe was also blown away after four-time NBA MVP LeBron James tweeted after his win, labeling him the "young king".

"I was losing it in the locker room. I was going crazy," he said. "That's my guy, so to see him post that, I was like do I retweet it as soon as he sent it? I was like, you know what, I'm going to be cool and act like I didn't see it and then retweet it three hours later."

Rafael Nadal was frustrated by his performance when speaking with the media after his upset loss against Frances Tiafoe in the fourth round, admitting "he was better than me".

Nadal only allowed two total break point opportunities from the first three sets, but he was unable to save either, leading to Tiafoe taking the first and third frames. 

The all-time leader in men's grand slams then was uncharacteristically shaky in the fourth, committing four double faults and more unforced errors (nine) than winners (seven).

While reporters questioned if it was the oppressive humidity, injuries, or even the distraction of the roof closing mid-match, Nadal made it clear his poor performance had a much simpler explanation.

"Well, the difference is easy," he said. "I played a bad match and he played a good match. At the end that's it, no?

"I was not able to hold a high level of tennis for a long time. I was not quick enough on my movements. He was able to take the ball too many times very early, so I was not able to push him back.

"Tennis is a sport of position a lot of times – if not, you need to be very, very quick and very young. I am not in that moment anymore.

"My shots need to be better. In some way my understanding of the game and the quality of my shots were not good enough. They were poor, I think I have to say today, because I was not able to create that much on him.

"Well done for him. He was better than me."

With the last grand slam of the year now in the books for Nadal, he said he will take some time away to recuperate, but was non-committal about when he may return.

"I need to go back [home], I need to fix things, life," he said. "Then I don't know when I'm going to come back. 

"I'm going to try to be ready mentally. When I feel that I will be ready to compete again, I will be there."

Frances Tiafoe produced a stunning performance to knock Rafael Nadal out of the US Open and reach the quarter-finals of his home grand slam for the first time.

Tiafoe was playing in the fourth round at Flushing Meadows for the third successive year, but his prospects of going beyond that point appeared slim against the 22-time grand slam champion.

Nadal had won his two previous encounters with Tiafoe but found the 24-year-old up to the challenge this time around, his firepower proving too much for his illustrious opponent.

So often Nadal has snatched victory from the jaws of defeat and there were moments during his epic that he seemed primed to do so again. Yet winning the second set and breaking at the start of the fourth both proved false dawns for Nadal, as Tiafoe prevailed 6-4 4-6 6-4 6-3 to blow a men's draw that has already lost 2021 champion Daniil Medvedev wide open.

It became clear early on that the pace of Tiafoe's ball-striking and the variety in his game would cause Nadal problems and he got the break his play deserved when the Spaniard sent a pair of forehands long in the seventh game.

Tiafoe rarely looked daunted by the occasion and though he let a pair of set points go begging after going 40-0 up at 5-4, he snatched the third with a volley to ensure Nadal would have to mount a comeback.

A classic Nadal turnaround appeared very much on the cards when Tiafoe's composure deserted him trailing 5-4 on serve in the second, a double fault from the American allowing Nadal to level the match.

But any thought of Nadal, curiously unable to make an impression on Tiafoe's second serve, dominating from there was soon extinguished, Tiafoe breaking for a 4-3 lead in the third with a searing backhand down the line.

Tiafoe consolidated with an intelligent serve and volley play on his second serve and, after a Nadal hold, made no mistake in winning the third set on his racquet with an ace.

Controversy soon followed as Nadal broke a furious Tiafoe with a vicious forehand in a game played as the Arthur Ashe Stadium roof was closing.

Tiafoe received a code violation for "audible obscenity" after venting his frustration at that decision by the tournament officials, but he harnessed his anger in the right way. Nadal sent down a pair of double faults in an uncharacteristically sloppy service game and Tiafoe capitalised with a cross-court backhand that proved too hot for the four-time champion to handle.

A backhand error from Nadal gave Tiafoe another break for a 4-3, and he subsequently raced to the finish line, getting 40-0 on Nadal's serve and then completing the fairytale with on his second match point as Nadal sent another backhand into the net.

Data Slam: Tiafoe hands Nadal first grand slam loss of 2022

After winning both the Australian Open and the French Open, and withdrawing from Wimbledon due to injury, this is Nadal's first loss at a grand slam this year.

Tiafoe also joins James Blake and Andy Roddick as the only Americans to ever defeat Nadal at a grand slam, and it snaps Nadal's streak of 16 consecutive grand slam quarter-final appearances.

Daniil Medvedev knows he has not performed to the best of his abilities at grand slams this season after his US Open title defence was ended by Nick Kyrgios.

Medvedev, who will also concede his spot at the top of the ATP's world rankings, has only won one of the four finals he has reached in 2022.

His record in the majors is a particular frustration for the 26-year-old. After losing to Rafael Nadal in the Australian Open final, Medvedev has reached the fourth round at Roland Garros and the same stage at Flushing Meadows, while The All England Club's ban on Russian and Belarusian athletes prevented him from competing at Wimbledon.

With Novak Djokovic unable to play in New York due to his COVID-19 vaccination status, Nadal, Carlos Alcaraz or Casper Ruud will become the world number one after the US Open's conclusion on Sunday.

"I mean, now that you say it, I remember it," Medvedev said in a press conference when asked how it felt to give up the number one spot.

"That's not nice because honestly after such a match, when you lose in a grand slam... I'm trying to look good here, but I'm disappointed.

"[I'm] not going to cry in the room, but I'm a little bit disappointed. For a few days I'm going to be just a little bit sad, looking at my phone, my laptop or watching some series.

"Yeah, it was not the first thing on my mind walking after the match, saying, 'Damn, I will not be the world number one anymore' – I actually don't know which place I will be. Probably three or four. I guess Carlos will pass me. I don't know actually.

"But that's motivation, try to do better. Obviously it was the last slam of the year. I didn't do well enough. Didn't win in Australia when I had the chance. Didn't get the chance to play at Wimbledon.

"Roland Garros, lost in the fourth round. Here, fourth round. Yeah, I should do better, should get more points if I want to be world number one again."

Medvedev went down 7-6 (13-11) 3-6 6-3 6-2 to Kyrgios, who has a 4-1 winning record against the Russian.

Asked if he thought it was Wimbledon finalist Kyrgios' best display against him, Medvedev suggested the Australian came close to replicating the form of greats Nadal and Djokovic.

"Yeah, it was a high-level match," he said. "[I] played Novak, Rafa. They all play amazing. Nick played kind of their level, in my opinion.

"He has a little bit different game because he's not a grinder in a way, [but] at the same time he can rally. He's tough to play.

"He has an amazing serve. He plays well, has every shot. It was a really high-level match from him.

"If he plays like this until the end of the tournament, he has all the chances to win it, but he's going to get tough opponents."

Nick Kyrgios took the opportunity to discuss the low points of his career after his victory over Daniil Medvedev, admitting he never thought he would have the chance to return to his best form.

Kyrgios conceded just one set to Medvedev in the 7-6 (13-11) 3-6 6-3 6-2 triumph at the US Open on Sunday.

It appeared during the first set tiebreaker that he was on the verge of one of his famous meltdowns, with a couple of racket slams and plenty of abuse towards his own box, but he steadied and fought back after a poor second frame.

Speaking to the media after the match, Kyrgios admitted the tiebreaker was do-or-die, saying: "I feel like if he'd got that first set, it was going to be pretty much an impossible task for me to come back and win."

This year's Wimbledon runner-up was humble and respectful when discussing the talent of Medvedev, and despite his muted celebration, highlighted what a big deal it is for him to perform well under the bright lights in New York.

"I didn't over-celebrate. It's only the fourth round, I've got quarter-finals [next]," Kyrgios said. "But it was an amazing experience obviously taking down the number one player in the world on Arthur Ashe Stadium.

"I don't really like to celebrate too much after that because I know that if I played him nine more times, he's probably getting on top of me the majority of the time.

"I hadn't won a match on Ashe before this week, now I've won two against two quality opponents, and I feel like I've been able to showcase [my talent].

"There's a lot of celebrities here, a lot of important people here watching. I wanted to get on that court and show them I am able to put my head down and play and win these big matches.

"For the tennis world I think it's important as well. People were really starting to doubt my ability to pull out matches like this at majors. I'm really proud of myself honestly because it hasn't been easy dealing with all the criticism."

Kyrgios continued to discuss how he feels he is perceived by the public and the media, saying it was more a feeling of relief than ecstasy when he finished the job.

"I feel like I'm more just proud of the way that I've bounced back after everything, honestly," he said. "I've been in some really tough situations mentally, and in some really scary places.

"Obviously if you look at it on paper, I probably wasn't expected to win that match. Maybe take a set or two if I'm lucky, give the people a show.

"It's a great win, but I come off the court and I'm just almost relieved that it's over because there's just so much pressure every time I go out on court, so much expectation, so much unpredictability of what I can do.

"I just sit there in the locker room after and I'm just super proud of the performance, because there was really a time where I didn't think I was capable of producing and doing this any more.

"I guess I'm just more relieved, and I'm super proud."

Nick Kyrgios is through to the quarter-final after a terrific 7-6 (11-13) 3-6 6-3 6-2 win over world number one and reigning US Open champion Daniil Medvedev.

It was a match that had all of the usual Kyrgios antics as he seemed to lose his cool during the first set tiebreaker, slamming his racket multiple times while repeatedly yelling at members of his entourage.

But he was able to work his way through it, saving three set points, before sealing the opening frame in 64 minutes with his fourth set point. Kyrgios relied on his dominant serve and limiting his errors, with just one double fault and 11 unforced errors with 21 winners.

The momentum from winning the set kept Kyrgios from spiralling mentally, but he became sloppy in the second, committing four double faults with only three aces, and he had 12 unforced errors with seven winners. It was the only set he had more than one double fault and more unforced errors than winners.

Zverev's ability to return in the second set was the difference, lifting his return point success rate from 33 per cent in the opener to 48 per cent to break twice and even up the match.

It had all the makings of a Kyrgios meltdown, but where he would usually begin to unravel and force desperate power shots to shorten points, he instead settled into the battle and refocused on getting into the net.

After only going to the net five times in the second set, he tripled that in the third, winning nine-of-15 attempts while not allowing a single break point opportunity. Kyrgios only created one break point chance for himself, and he took it with both hands to go up two sets to one.

In the fourth, Kyrgios was able to break again with his first opportunity early on, and with his serve switched on and firing he would only allow one chance for Zverev to break back, but he snuffed it out before going on to secure a second break and the victory.

Of their five career meetings, Kyrgios has now won four, and he will now get the benefit of the number one seed's path through the tournament. Next up, he will face 27th seed Karen Khachanov in the quarter-final as he searches for his first career grand slam title.

Data Slam: Kyrgios accomplishes feat not seen since 1987

Kyrgios is the first player since 1987 to defeat the world number one twice in the same year, with Australian compatriot Pat Cash the last to do it.

It is also the first time an Australian has defeated a world number one in a grand slam since Kyrgios himself, back in 2014 as a 19-year-old against Rafael Nadal at Wimbledon.

Rafael Nadal says his third-round win over Richard Gasquet was his best of this year's US Open as he works his way back after the abdominal tear that ended his Wimbledon campaign.

Prior to the US Open, Nadal had only played once since withdrawing from the Wimbledon semi-final against Nick Kyrgios in early July, losing to Borna Coric in Cincinnati.

The second seed got past Rinky Hijikata and Fabio Fognini in four sets in the first two rounds at Flushing Meadows before Saturday's 6-0 6-1 7-5 win over French veteran Richard Gasquet in two hours and 17 minutes.

"My best match in the tournament," Nadal told reporters. "Easy to say that because the other day was tough.

"But important improvement. But I need to keep going. It's a good victory for me. Straight sets for the first time. Third set had been a challenge. He increased the level.

"I went through some difficult moments. That's something that is good that I went through that and saved that moments with a positive feelings. Happy to be in the fourth round, without a doubt."

The victory over Gasquet meant he has progressed to the second week at Flushing Meadows for the 12th time in his career, although he conceded he would need to lift his level to take out the title, starting with Monday's fourth-round match with 22nd seed Frances Tiafoe.

Nadal is gunning for his third major title this calendar year in New York, having triumphed at the Australian Open and French Open.

The 36-year-old's Australian Open success in February came after minimal preparation due to a foot injury, similar to his US Open lead-up due to the abdominal issue.

"I think I played better in Australia than here going to the second week," Nadal said. "But I have zero background in terms of victories and all this stuff.

"Here I played little bit worse than in Australia, without a doubt. But the story of the year and the results on the slams have been incredible, so that helps.

"I don't know the balance, what's better or worse. But all these victories help to be a little bit more confident. It's a moment to increase, to making a step forward."

"Second week against a great player like Frances, I need to be ready to play and to raise my level. I hope to be able to make that happen.

"I know is the right moment to make an improvement if I want to keep having chances to keep going on the tournament."

Second seed Rafael Nadal continued his staggering head-to-head domination of Richard Gasquet as he cruised into the fourth round at the US Open with a straight-sets victory on Saturday.

The 22-time major winner was irrepressible across the first two sets before Gasquet rallied in the third, but Nadal triumphed 6-0 6-1 7-5 in two hours and 17 minutes.

The victory means the 2022 Australian Open and French Open champion will face 22nd seed Frances Tiafoe in the fourth round and improves his head-to-head record against Gasquet to 18-0.

Nadal, who had been shaky early against Fabio Fognini last round, was ruthless when it mattered, hitting 35 winners for the match and winning 78 per cent on his first serve.

After dropping the opening sets in his previous two matches against Fognini and Rinky Hijikata, Nadal responded with a flawless first frame that included converting three of six break points.

Gasquet's belief seemed completely gone in the second set, managing no winners, with Nadal in control. The Frenchman ended Nadal's nine-game winning run to loud applause, raising his arms in celebration and probable relief.

Nadal broke early in the third but Gasquet responded to break back, pushing hard in the third set. But the Spaniard's quality shone highlighted by his finesse with a lob helping him claim the decisive break in the 11th game.

Data Slam: Rafa's longevity on show

Saturday's win was Nadal's 30th at night at Arthur Ashe Stadium and took his tally to 22-0 at majors this year, having only withdrawn from Wimbledon due to an abdominal injury. The triumph also saw him progress to the second week at Flushing Meadows for the 12th time in his decorated career, that includes four US Open titles.

Matteo Berrettini outlined his desire to see Roger Federer return to the court as he compared the 20-time grand slam champion to retiring legend Serena Williams.

Federer has not played competitively since losing to Hubert Hurkacz in the Wimbledon quarter-finals last year, and has since undergone his third knee surgery in two years.

But the 41-year-old is hopeful of returning to the court for this month's Laver Cup, where he is set to team up with Rafael Nadal, Andy Murray and Novak Djokovic for Team Europe.

Federer recently shared an encouraging video of a practice session on social media after stepping up his rehabilitation. 

With tennis set to lose one legend after Williams' final US Open campaign was ended by Ajla Tomljanovic on Friday, the return of Federer would represent a major boost for the sport.

Speaking after beating Murray in the third round at Flushing Meadows, Berrettini said: "I think I said it so many times. Probably it's never going to be enough. One of the reasons why I'm here now is Roger. 

"He was my idol when I was growing up. I was cheering for him, so I want him back really badly.

"He's just like Serena, I guess, one of a kind, you know?

"I wish him a really speedy recovery in whatever he's doing to come back. I wish I could play one more time against him."

Berrettini has lost each of his two tour-level matches against Federer, including a straight-sets defeat at Wimbledon in 2019.

Nick Kyrgios believes no other player will be able to emulate the career Serena Williams has enjoyed, after the grand slam great confirmed her retirement.

Williams went down 7-5 6-7 (4-7) 6-1 to Ajla Tomljanovic – Kyrgios' former partner – on Friday in the third round of the US Open.

That brought an end to her playing career, though the 40-year-old suggested she would leave the door open for a potential return.

Kyrgios, who defeated J.J. Wolf to set up a contest with reigning men's champion Daniil Medvedev, is in awe of what Williams has achieved, as he ranked the 23-time grand slam champion alongside Rafael Nadal, Roger Federer and Novak Djokovic.

"She's had a career that I don’t think no one else will emulate," Kyrgios said.

"You've got a couple on the men’s side who are trying to catch her in grand slams, but Nadal, Serena, Federer, Novak, these are once in a generation athletes – I wouldn't even put myself in the same category, ever.

"It's a special moment for her, she played extremely well, she won two matches and nearly got on top [against Tomljanovic], it's a hell of a way to go out.

"I just appreciate what she's done and I'm sure everyone in this building does as well."

After beating Wu Yibing, world number one Medvedev said of Williams: "That was a crazy match, it was close to being three hours.

"It's definitely a pity that she lost. If it's the last match of her career, it was definitely an amazing match and she was really close to winning.

"Ajla played at a great level, it was not easy against the crowd and it was a high-level match."

Williams bows out with the most grand slam wins in the Open Era of any player, male or female.

Daniil Medvedev has described both himself and US Open fourth-round opponent Nick Kyrgios as "electric", but says the pair share more "respect" than friendship.

The world number one will continue his men's single title defence against the Australian in the last 16 at Flushing Meadows after a 6-4 6-2 6-2 Win over China's Wu Yibing.

The pair are set to meet for the fifth time on the ATP Tour, with Kyrgios holding an impressive 3-1 record over the Russian in their previous four encounters, including in the final of the 2019 Citi Open.

But Medvedev defeated the former on home turf at the Australian Open earlier this year, in arguably the biggest clash between the duo.

Speaking ahead of the pair's encounter, Medvedev stressed he does not see the pair as friends, but he has strong admiration for his opponent's game and is impressed at how he has revived his fortunes this year.

"I don't think we are friends," he added. "I feel like we respect each other a lot. We are both quite electric. You never know what's going to happen in the future

"Nick is a little bit different from other tennis players on the court. That's his choice. That's his life. I'm not the one to judge. I feel a lot of respect for him."

Asked if he is surprised at Kyrgios' improved form following a first grand slam final this year at Wimbledon, Medvedev added: "To be honest, yes.

"We all knew that he's capable of doing big things. We always knew on [his] day, he is capable of beating anyone.He [has] proved it many times, against the biggest players in the world."

Kyrgios, meanwhile, is relishing another battle on a big occasion, adding that his attempts to seize victory against the odds of public opinion allow him to "thrive".

"You want to be in those moments," he said. "I want to be playing on the biggest stadiums in the world in front of millions of people broadcasted globally. That's where I want to be. That is why I work hard.

"It makes it even sweeter. I know a lot of people don't want me to succeed. I know a lot of people hate my game, the way I do things, the way I go about it. I always thrive on it. I never want to forget all the things people say.

"I always carry this chip on my shoulder. Win or lose, I'm proud of how far I've come. I think that's where every tennis player wants to be, playing the best players in the world in the best stadiums in the world."

World number one Daniil Medvedev was levels above his third-round opponent Yibing Wu on Friday, defeating him 6-4 6-2 6-2 to set up a highly anticipated clash with Nick Kyrgios in his next match.

While Medvedev had the clear power advantage – finishing with 10 more winners and 11 more aces – he also allowed Wu to beat himself, with 18 unforced errors and three winners in the opening set.

Despite his early wastefulness, Wu still created six break point opportunities in the opening set, but could only capitalise on one. It would be his last break of the match as Medvedev tightened the screws down the stretch.

The Russian took the first four matches of the second set to take away any hope Wu had of fighting back into the contest, and in the third set Medvedev's serve really hit top gear.

He faced no break point opportunities in the final frame as he converted over 70 per cent of his points on both first serves (13-of-18) and second serves (eight-of-11), while Wu's errors returned, with 15 and just four winners.

Against Kyrgios next, Medvedev will be looking for his second win against the Australian in their fifth meeting. In their two matches this year – and their only two since 2019 – Medvedev won in four sets at the Australian Open, before Kyrgios got one back at the Canadian Open.

Nick Kyrgios was far too good J.J. Wolf in the third round of the US Open on Friday, not having his serve broken a single time in the 6-4 6-2 6-3 victory.

Kyrgios dominated the match with his serve, racking up 21 aces to Wolf's five, and of the seven break point opportunities the Australian allowed, he saved all seven.

His return game was sharp as well, creating 11 break points and converting five, and he used it to break away in the second set, rattling off five consecutive games to comfortably go up two sets to love.

The third set was more competitive as Kyrgios had a pair of double faults, and more unforced errors (17) than winners (16), but he ultimately had too much firepower for the 23-year-old American.

After coming back from a love-40 deficit, saving four break points in the game, Kyrgios put the finishing touches on the straight sets win with another break of serve to seal it.

With the win, he books his spot in the fourth round, where he will meet world number one Daniil Medvedev.

Kyrgios has won three of the four career meetings between the pair, including their most recent fixture at the Canadian Open.

Andy Murray has admitted he is "surprised" to still be able to compete against top-level opponents given his injury history.

The 2012 US Open champion exited this year's competition following a third-round defeat to 13th seed Matteo Berrettini, though he did take the tie to four sets.

Having lost the first two sets, Murray fought back to win the tiebreaker in the third but his valiant attempts were ended by the Italian in the fourth, who sets up a round of 16 clash against Alejandro Davidovich Fokina.

Despite the loss, Murray was pleased with his performance at the tournament and encouraged by his ability to still go toe-to-toe with the likes of Berrettini.

"I've got a metal hip. It's not easy playing with that. It's really difficult. I'm surprised I'm still able to compete with guys that are right up at the top of the game," he said after the match.

"Matches like this, you know, I'm really proud that I have worked myself into a position where I'm able to do that. I'm really disappointed that I didn't get over the line today. 

"But I get reminded like 'this is the first time you've made the third round here since 2016'. It's been six years. It's been a difficult six years for me. It's been really hard.

"Although it's the first time I've only made the third round here, I'm really proud of that effort that I put in to get myself back into these positions. So, I'm hoping that in the future I can go further, but considering, I did all right."

Murray went on to explain how things feel differently for him on the court, identifying he cannot move in the same way Rafael Nadal and Novak Djokovic still can.

"A lot of the things feel the same, but obviously I'm just not quite capable of the sort of movement and physicality that I was five, six years ago. I mean, that's pretty obvious. You know, I shouldn't expect to be," he said.

"I think if you watch Rafa and Novak moving around the court now who are similar age, I think they're moving pretty similar to how they were five, six years ago, whereas for me there's obviously been a bit of a drop-off there.

"That can affect you in terms of how you have to play the points. Maybe you just don't track as many balls down as before. Maybe the reach isn't just quite as much as it was.

"But in terms of the shots and everything, there is nothing that is stopping me from hitting the same shots as I did before."
