Daniil Medvedev feels he may have been at a disadvantage in his opening match at the Paris Masters, going down 6-4 2-6 7-5 against Alex de Minaur in the second round.

While it was De Minaur's second match of the week, having fought his way through the first round in a three-set win against Sebastian Korda, Medvedev had the bye straight through to round two.

He pointed to that fact when discussing what he thinks went wrong for him, while also crediting De Minaur for rising to the occasion during big points.

In his post-match press conference, Medvedev said he did not feel he played poorly, but De Minaur was just in terrific touch.

"I think he played pretty well," he said. "I think even in the third set I had the break up, and he played an amazing game on my serve where I served only first serves, and he made some winners. 

"Actually, I think I had my chances to win the match – but didn't use them – and he managed to keep enough pressure on me at the end of the match to win.

"But that's tennis, you know. Like I just watched Felix [Auger-Aliassime] win [in a close third-set tiebreaker] and I'm going, 'whoever loses this match is gonna hate tennis for a few days'... two people, only one can win."

When asked if his victory at the Vienna Open – where he beat Denis Shapovalov in the final just four days ago – had him feeling not at his sharpest on such a quick turnaround, he admitted it was a factor.

"Well, I had a lot of matches under my belt back to back, and it's never easy," he said. "The positive thing is that you feel confident. 

"My impression, if you win the first match of the week, that's where you really have a lot of feelings and you have a confidence boost for the next match.

"But it's the first match that is the toughest. It was a tough match. Alex played very well. Had he played a bit less well, I would have won. But he did his job, you know, and he won."

Medvedev will be part of the field contesting the ATP Finals in Turin later this month.

Rafael Nadal joined Daniil Medvedev in making a shock early exit from the Paris Masters on Wednesday.

While world number one Carlos Alcaraz overcame Yoshihito Nishioka 6-4 6-4 to progress to the last 16, there was no such luck for compatriot Nadal, whose chances of ending the year at the top of the ATP rankings are over after a defeat to Tommy Paul.

World number two Nadal looked well set to progress after claiming the first set 6-3 in just over 40 minutes, yet American Paul rallied to seal the biggest win of his career 3-6 7-6 (7-4) 6-1.

The 22-time grand slam champion said on Tuesday that he is no longer concerned with competing for the top spot in the world, though he will no doubt be frustrated at bowing out at the first hurdle ahead of the ATP Finals later this month.

Paul became the first player to defeat Nadal prior to the quarter-finals of the tournament when he sent a controlled backhand volley away from the forlorn 36-year-old.

Nadal was not the only big-name exit, with world number three Medvedev also slumping to defeat, going down 6-4 2-6 7-5 to Alex de Minaur.

For Australian De Minaur, it was his first win in 19 attempts against a player ranked in the top five and sets up a third-round clash with Frances Tiafoe, who beat Jack Draper.

"It's a good one to get, for sure," said De Minaur. "It's the end of the year, everyone's a bit tired, but I'm very proud of my performance. I just played very smart.

"I knew it was going to be a chess match out there, both baiting each other to be aggressive, but you also didn't want to be too aggressive at times. It was an absolute battle and I'm very happy I was able to come out on top."

It leaves the path open for Alcaraz to retain his place as the world's best player, and the 19-year-old said after his win: "First round in every tournament is never easy.

"You have to be really focused, you have to try to get a good rhythm, good feeling in the first round. I'm really happy with the performance, the level that I played, and I'm looking forward to getting better in the next round."

Ninth seed Taylor Fritz and 10th seed Hubert Hurkacz lost to Gilles Simon and Holger Rune respectively, their defeats ensuring Felix Auger-Aliassime, who overcame Mikael Ymer, and Andrey Rublev will feature in the ATP Finals.

Auger-Aliassime's victory took three hours and 30 minutes, and marked his 14th win in a row.

"Somehow I found a second wind after saving those break points at 4-1," said the Canadian.

"I played better and better, coming through the court much better, serving better. It was pretty epic. Three hours and 30 minutes on the court, quality rallies. He was making me work all the time. Definitely a win to remember."

Fifth seed Stefanos Tsitsipas was also a winner, seeing off Daniel Evans in straight sets.

Daniil Medvedev celebrated "one of the best victories" as he beat Denis Shapovalov 4-6 6-3 6-2 in the final of the Vienna Open on Sunday.

Playing in his first tour-level final since winning the Mexico Open in August, Medvedev found himself on the back foot after Shapovalov came out on top in a 50-minute opener.

The world number four conceded serve twice in the first set – the first time he had been broken throughout his run in Austria.

However, Medvedev hit back to claim the second set at the first time of asking.

Having lost serve twice in the decider, Shapovalov hung on in to frustrate Medvedev, saving six match points before finally succumbing to a deft drop-shot that the Canadian could only clip back into the net.

The victory marks Medvedev's second title of 2022, while it also ensures the Russian – who worked his way to world number one earlier in the year – will play in the ATP Finals next month, after going for glory at the Paris Masters.

"This match was the best of the week because Denis was really playing unreal until probably 4-3 in the second set," said Medvedev, who is aiming for a strong end to the season.

"He dropped his level by maybe two per cent and I was able to use it. This is one of the best victories when you know your opponent is on top of you, but you try and stay there and do what you can.

"I like to play indoor hard courts at the end of the season. I feel that I do a great job with my team not to arrive burnt out.

"I'm looking forward to the last two tournaments of the year which are really important and I usually play well."

World number one Carlos Alcaraz was stunned in the Swiss Indoors Basel semi-finals as Felix Auger-Aliassime set up a final clash with Holger Rune.

Auger-Aliassime saw off the US Open champion in just 82 minutes as he won 6-4 6-3 to take his unbeaten run to 12 matches.

The Canadian was in irresistible form on Saturday, with his shot placement in decisive moments proving far more consistent and lethal than his counterpart, hitting 23 winners to Alcaraz's eight.

Twenty-two-year-old Auger-Aliassime is still fighting to qualify for the ATP Finals for the first time and victory in Sunday's final will move him up to sixth in the rankings having won each of his two previous tournaments in Antwerp and Florence.

"It's amazing," Auger-Aliassime said. "I never expected it, when I was in Florence three weeks ago, or after the US Open. I'm just really happy that all my work is coming together.

"I've always believed that I can play this way, that I can be consistent in that way, but one thing is to believe and the other is to actually do it. It's nice to feel that way, it's nice to come out on the court and win that many matches in a row. So hopefully this is just the beginning of seeing me play this way."

Rune awaits after the Dane beat Roberto Bautista Agut 7-6 (7-1) 7-6 (10-8) despite being 6-2 down in the second-set tie-break. He will move into the top 20 for the first time as a result of that win.

The final of the Vienna Open will be contested by Daniil Medvedev and Denis Shapovalov, who came through their respective semis in straight sets.

Top seed Medvedev was exceptional against Grigor Dimitrov, with the Russian's serve proving especially important in his 6-4 6-2 win.

Medvedev won 87 per cent of points on his first serve to leave Dimitrov frequently struggling for momentum, and the former world number one recognised that impact.

"The serve is probably the most important shot in tennis," he said. "I was lacking it a little bit this season, I was doing too many double faults. Sometimes in important moments my serve could have been a little bit better. I was working a lot with my coach to try and find this rhythm [again], and so far I'm serving good here. I'm really happy about it and that's also why I'm playing so good."

Shapovalov ultimately romped to an impressive win over Borna Coric.

A tight first set was followed by the Croatian getting bageled as Shapovalov won 7-6 (7-4) 6-0 to reach his second final of the year.

World number one Carlos Alcaraz is through to the semi-finals of the Swiss Indoors Basel after easing past Pablo Carreno-Busta in straight sets.

Alcaraz took just under an hour and 40 minutes to overcome his fellow Spaniard and friend 6-3 6-4, getting 67 per cent of his first serves in and winning 77 per cent of those.

Carreno-Busta struggled to keep the US Open champion at bay, facing 12 break points in all, and although he saved nine of them, his defiance was ultimately in vain.

"It is difficult to play against a friend like Pablo," Alcaraz said on-court after his win on Friday. "Every day we go and have dinner, lunch, together. Every week and we train together, so it is difficult to play against him.

"I also support him and want him to win every match. On court, there are no friends. You have to be focused and go for the match and that is what I did."

Alcaraz will face third seed Felix Auger-Aliassime in the final four after the Canadian defeated Alexander Bublik 6-2 6-3.

The other semi-final will see Roberto Bautista Agut play Holger Rune after the Spaniard beat Stan Wawrinka 7-5 7-6 (7-5) and the Danish teenager defeated Arthur Rinderknech 7-6 (7-0) 6-2.

In Austria, top seed at the Vienna Open Daniil Medvedev beat Jannik Sinner 6-4 6-2 to advance to the last four, where he will play Grigor Dimitrov after the Bulgarian overcame Marcos Giron 6-3 4-6 6-4.

The winner of that contest will face either Denis Shapovalov, who beat Dan Evans 6-3 6-3, or Borna Coric after the Croatian came through against Hubert Hurkacz 6-4 6-7 (2-7) 7-6 (7-5).

Stefanos Tsitsipas crashed out of the Vienna Open after losing in a dramatic third-set tie-break against Borna Coric, who claimed his third successive win over the Greek ace.

The second seed was the highest-profile casualty in the Austrian capital on Thursday, as he succumbed to the Croatian once more 4-6 6-4 7-6 (7-4).

Coric rescued six match points before stunning Tsitsipas at the 2020 US Open, while he also triumphed when they collided in the Cincinnati showpiece in August.

The world number 27's chances of completing a hat-trick of victories appeared bleak at a set and break down, but he rallied to force a decider that went the distance, before holding his nerve for another notable win.

Coric's reward is a quarter-final clash with Hubert Hurkacz, who boosted his chances of qualifying for next month's ATP Finals with a 7-5 4-6 6-3 win over Emil Ruusuvuori.

Daniil Medvedev advanced to the last eight after a 6-3 6-3 victory over home favourite Dominic Thiem. Next up for the top seed is Jannik Sinner after the Italian saw off Francisco Cerundolo 7-5 6-3.

Third seed Andrey Rublev's ATP Finals hopes were dented after a 6-3 6-4 defeat by Grigor Dimitrov, who will play Marcos Giron after the American overcame seventh seed Cameron Norrie in straight sets.

Over in Basel, third seed Felix Auger-Aliassime required just 49 minutes to complete a commanding 6-1 6-0 rout of Miomir Kecmanovic for his 10th straight ATP win.

Meanwhile, Stockholm champion Holger Rune continued his momentum by recording a seventh straight victory after seeing off Ugo Humbert 6-4 6-2.

Sixth seed Roberto Bautista Agut enjoyed a straight-sets win over three-time grand slam champion Andy Murray to set up a clash with home favourite Stan Wawrinka, who outlasted Brandon Nakashima in a deciding set.

Daniil Medvedev set up a second-round showdown with home favourite Dominic Thiem at the Vienna Open after defeating Nikoloz Basilashvili in straight sets on Wednesday.

The top seed broke early and late in both sets as he cruised through the opening round a 6-2 6-2 winner.

Next up for Medvedev is a clash with former US Open champion Thiem, who beat him in the semi-finals on the way to triumphing at Flushing Meadows two years ago.

Stefanos Tsitsipas overcame local wildcard Dennis Novak 7-6 (7-2) 6-2 as the Greek ace seeks a third final in as many weeks, having lifted the title in Astana and finished as runner-up to Holger Rune in Stockholm.

Jannik Sinner also advanced in straight sets against Cristian Garin, but Taylor Fritz's ATP Finals hopes suffered a blow after the fourth seed was beaten 6-1 4-6 6-3 by Denis Shapovalov.

Over in Basel, world number one Carlos Alcaraz sailed through to his 11th quarter-final of the season after a commanding 6-4 6-2 win over Botic van de Zandschulp.

Meanwhile, Felix Auger-Aliassime recovered from losing the opening set to deny Marc-Andrea Huesler. The third seed claimed a career-best ninth successive ATP Tour victory, as he looks to complete a hat-trick of titles in as many weeks having recently reigned in Florence and Antwerp.

Stockholm champion Rune built on his recent momentum with a 6-2 7-5 success over Alex de Minaur, but Naples winner Lorenzo Musetti was ousted in a deciding set by Albert Ramos-Vinolas. 

Novak Djokovic progressed to the Astana Open final after Daniil Medvedev retired from their last-four clash due to injury.

The two played out a thrilling first two sets, with Medvedev taking the lead before Djokovic fought back to level the match via a tie-break.

However, the Russian was unable to continue after sustaining a leg injury, keeping Djokovic in the hunt for back-to-back titles when he competes in the showpiece, where he will face Stefanos Tsitsipas.

"I really hope that his injury is nothing too serious,” said Djokovic. "I know Daniil, he's a great guy, he's a fighter, he's a big competitor.

"He wouldn't retire a match if he didn't feel that he [could] continue or [if it wouldn't] worsen his injury. He told me that he pulled an adductor muscle in his leg.

"It was such a close match, particularly in the second set. I would probably say he was a better player on the court in both sets. I was fighting and trying to find a way.

"I found a way to win the second, but I'm just sad for the tournament and for these people who were enjoying the battle, and for Daniil that it had to end this way."

Third seed Tsitsipas started slowly in the first set against Andrey Rublev but managed to triumph 4-6 6-4 6-3 in Saturday's other semi-final.

"My mentality kind of changed," said Tsitsipas, who will seek his first ATP 500 title at the ninth attempt. "I played with more of an aggressive game style and didn’t have anything by luck."

At the Japan Open, Taylor Fritz battled back from 3-1 down in the deciding set against Denis Shapovalov to claim a 6-3 6-7 (5-7) 6-3 semi-final victory and book his place in his third ATP Tour final this season.

Third seed Fritz faces an all-American clash in Sunday's final against Frances Tiafoe, who dropped his first set of the week as Soonwoo Kwon bageled him, but the US Open semi-finalist recorded a 6-2 0-6 6-4 win.

"It was a weird match, but I'm happy to get through," said Tiafoe, who progressed into his second final of the season and fifth overall.

"It's not always going to be pretty, it's not always going to be the best stuff, but a win is what matters."

Novak Djokovic set up a semi-final meeting with Daniil Medvedev at the Astana Open on Friday, cruising past Karen Khachanov in the last eight.

Djokovic complemented a fine display of serving by converting three of his five break points in a 6-4 6-3 victory, recording his seventh consecutive win following his absence from the US Open.

The 21-time grand slam champion has now reached six semi-finals this year, but saw room for improvement in his performance after beating the world number 18.

"I didn't play as well from the baseline as I did in the first two matches, but still it was enough," Djokovic said. "I managed to produce some good tennis when it was most needed in both sets."

Looking ahead to his final-four match, the Serb added: "I always expect highs from myself. Hopefully I can elevate still the level of my game for tomorrow, because it's going to be needed." 

Djokovic will face an 11th tour-level meeting with Medvedev in the next round after his fellow former world number one recorded a dominant 6-1 6-1 win over Roberto Bautista Agut.

On the other side of the draw, third seed Stefanos Tsitsipas beat Hubert Hurkacz 7-6 (10-8) 6-3, and will now face Andrey Rublev after he eased to a 6-1 6-2 win over Adrian Mannarino.

At the Japan Open, a knee injury forced Wimbledon runner-up Nick Kyrgios to withdraw from his meeting with Taylor Fritz, with the American set to take on Denis Shapovalov in the semi-finals.

Seventh seed Shapovalov saw off Borna Coric 6-4 6-3 to reach the final four, while fourth seed Frances Tiafoe advanced with a 6-0 6-4 win against Miomir Kecmanovic.

South Korea's Kwon Soon-woo claimed the final place in the semi-finals in Tokyo, beating Spain's Pedro Martinez 6-3 6-0

Daniil Medvedev succumbed to second-round defeat against Stan Wawrinka at the Moselle Open on Thursday, while Hubert Hurkacz coasted past Dominic Thiem.

World number four Medvedev fell to a 6-4 6-7 (7-9) 6-3 loss against three-time major winner Wawrinka, who will next meet Mikael Ymer after his straight-sets win over home favourite Gregoire Barrere.

Second seed Hurkacz did not experience such struggles against Thiem as the Pole cruised to a 6-3 6-4 as he served 12 aces in a dominant performance in Metz.

Hurkacz will face Arthur Rinderknech in the next round after the Frenchman battled to a 7-6 (13-11) 6-3 triumph over fifth seed Nikoloz Basilashvili.

Alexander Bublik, the seventh favourite in France, was also made to work for his progress to the quarter-finals, downing Emil Ruusuvuori 6-7 (4-7) 6-4 6-3.

Fourth seed Holger Rune awaits Bublik after Benjamin Bonzi retired due to injury when 6-4 4-1 down against the Dane.

Lorenzo Sonego coasted through his second-round clash to defeat Gilles Simon 7-6 (7-2) 6-4 to tee up a last-eight clash with Sebastian Korda.

Stan Wawrinka will face Daniil Medvedev in the second round of the Moselle Open after beating Joao Sousa in straight sets.

Wawrinka came through two qualifying matches to take his place in the main draw before defeating Sousa 7-6 (7-1) 6-2 in Metz on Wednesday.

The three-time grand slam champion's victory was only his fourth in a main draw at tour-level this year following a 13-month absence due to a foot injury.

Wawrinka said after setting up a showdown with top seed Medvedev: "It's the first time I won three matches in the same tournament for more than two years, so it's great.

"I'm getting confidence from winning a few matches, so I'm feeling a bit more relaxed, the way I'm moving. I think the level was good from me, and I'm happy with the win."

Dominic Thiem also advanced at the indoor hard-court event, seeing off Richard Gasquet 6-3 7-6 (7-3). 

Sebastian Korda was the first man to seal a quarter-final spot, sending third seed Lorenzo Musetti packing with a 6-3 7-6 (8-6) victory in the last match of the day.

Meanwhile, Alexander Bublik, Gregoire Barrere and Benjamin Bonzi were the other first-round winners.

The career of Carlos Alcaraz could be one that takes up a great deal of space in the record books, and he is getting started early.

Not yet old enough to buy a stiff drink in a New York bar, the 19-year-old was the toast of Flushing Meadows after a late-night win over Marin Cilic that ran into the early hours of Tuesday.

That five-set win against the 2014 champion, combined with the shock exit of Rafael Nadal at Frances Tiafoe's hands, has raised expectations that Alcaraz could scoop a first grand slam title on Sunday.

Should he land that breakthrough major, there will be another feather in his cap, making Alcaraz the youngest world number one since the ATP rankings were established in 1973, and the first teenager to hold down top spot. He has climbed from 32nd at the start of the year to his current position of fourth on the list.

Nadal is poised to go to number one, which he last held in February 2020, unless Alcaraz or 23-year-old Norwegian Casper Ruud reach the title match. They are the only two players remaining in the draw who can clamber to the top ranking, which Daniil Medvedev will relinquish after his fourth-round exit to Nick Kyrgios.

If both reach the final, the champion will go to number one.

In the city that never sleeps, Alcaraz completed a 6-4 3-6 6-4 4-6 6-3 win over Croatian Cilic at 02:23 local time, three minutes short of matching the latest finish in US Open history, shared jointly by three matches: Mats Wilander vs Mikael Pernfors (1993), John Isner v Philipp Kohlschreiber (2012), Kei Nishikori v Milos Raonic (2014).

The victory on Arthur Ashe Stadium made Alcaraz the youngest man to reach back-to-back US Open quarter-finals since Australians Lew Hoad and Ken Rosewall both achieved the feat before turning 19 in 1953. It was called the US Championships in that era.

Alcaraz has won a tour-leading 48 matches in 2022 and has become the youngest man to reach three grand slam quarter-finals since Michael Chang over 30 years ago.

However, he next faces a player making his own history.

Alcaraz's quarter-final opponent is a recent nemesis: Jannik Sinner, the 21-year-old Italian who beat him in round four at Wimbledon and again in the final of the clay-court event in Umag, Croatia, at the end of July.

"I played a couple of times against him," Alcaraz said. "He's a great player, really tough one. I lost twice in two months [to him] so I will have to be ready for this battle against Jannik."

There is a victory that Alcaraz could point to, having defeated Sinner on an indoor hard court at the Paris Masters last November, but they have never played on an outdoor hard court, which is where they will do battle on Wednesday.

Sinner has now reached the quarter-final stage of all four majors, becoming the youngest man to pull off that feat since a 20-year-old Novak Djokovic completed the set in 2008.

The last-eight duel with Alcaraz could be a sizzling clash, albeit Alcaraz and Sinner had some recharging to do on Tuesday after both were pushed to five sets in round four, in Sinner's case by Ilya Ivashka of Belarus. Alcaraz now has a 6-1 win-loss record in five-set matches.

Nobody remaining in the men's quarter-finals has a slam title to their name, and Alcaraz will hope he continues to have the backing of the crowd in Queens.

He said after fending off Cilic: "Of course, the support today in Arthur Ashe was crazy. After losing the fourth set, it was tough for me to come back in the fifth set, to stay strong mentally. But the energy I received today made me win."

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.

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."
