Nick Kyrgios

The pair were once grudge rivals, with Kyrgios ripping into Djokovic on the 'No Challenges Remaining' podcast in 2019, saying the Serbian had "a sick obsession" with wanting to be popular, in the way Roger Federer has enjoyed the love of tennis crowds.

More recently, though, Kyrgios sympathised with Djokovic's plight in January when the Serbian was detained and ultimately deported from Australia in a row over his vaccination status.

That served to stem the flow of bad blood, and Kyrgios has gone as far as to suggest there is a budding "bromance" between the pair.

Djokovic is not quite so sure about that, but the needle that once existed is unlikely to be a factor on Sunday, at least initially. Given the volatility both men may bring onto the court, the rapport could be seriously tested as the match goes on.

Even Djokovic has forecast "fireworks", but that does not necessarily mean ill-feeling.

On Centre Court, Djokovic will be aiming for his seventh Wimbledon title, which would see him tie Pete Sampras as the second most prolific winner of the men's singles in the Open Era, behind Federer's haul of eight.

On Saturday, Serbian journalist Sasa Ozmo quoted a conversation between the pair at Wimbledon's Aorangi practice courts, where Djokovic is said to have told Kyrgios: "It took you five years to say something nice about me, haha."

According to Ozmo, who reports for Sport Klub, Kyrgios replied: "But I defended you when it mattered."

Djokovic then reportedly said: "You did, I appreciate that."

The conversation continued on social media, with Kyrgios writing on Instagram: "We friends now?"

Djokovic quipped in reply: "If you are inviting me for a drink or dinner, I accept. P.S. Winner of tomorrow pays."

Kyrgios was not satisfied with that level of celebration, proposing instead: "Let's go to a nightclub and go nuts."

Djokovic and Kyrgios have played twice before, and Kyrgios won both times without dropping a set. They came in 2017 though, at Acapulco and Indian Wells, when Djokovic was at a relatively low ebb.

Now the 35-year-old from Belgrade is targeting a title that would take him to a career haul of 21 grand slam titles, one behind men's all-time leader Rafael Nadal.

It will be a 32nd grand slam final for Djokovic, a men's record, and he is chasing a fourth consecutive Wimbledon title, and a seventh in all. His lone defeat in a Wimbledon final came in 2013 when Andy Murray beat him in straight sets.

In contrast, Kyrgios will be contesting his first grand slam singles final. He won the doubles with Thanasi Kokkinakis at the Australian Open in January, but this is a massive step up, and he could be coming in slightly cold, after his semi-final against Nadal was cancelled due to the Spaniard's injury withdrawal.

The last Australian men's champion at Wimbledon was Lleyton Hewitt in 2002, but Ash Barty delivered in the women's singles last year, before retiring in March.

Kyrgios, at 40th in the ATP rankings, is the lowest-ranked Wimbledon men's singles finalist since 2003 when his fellow Australian Mark Philippoussis was a lowly 48th on the list.

He is the first unseeded man to reach a slam final since Jo-Wilfried Tsonga at the 2008 Australian Open.

Djokovic beat Tsonga that day to land his first grand slam title, and has enjoyed 14 years of plenty since.

That serves as a reminder of the company Kyrgios will be keeping, potentially out of his depth but maybe just enough of a threat if all aspects of his game come together.

First-time finalist Kyrgios had lauded his opponent as "a bit of a god" on court after a 21st grand slam success, with Djokovic ultimately having too much for his opponent.

And those generous words continued in the interview room, where Kyrgios acknowledged Djokovic's renowned return ability was a huge factor in the result – as was his composure.

Kyrgios had started beautifully, winning 81 per cent of his service points in the opening set and taking advantage of a pair of double-faults to grab the early advantage.

But Djokovic's return game picked up from that point, taking the sting out of the Australian's best weapon as his success rate on serve plummeted, winning 57 per cent of his service points in the second frame and 58 per cent in the third.

Kyrgios also committed four double-faults in the third to hand a set advantage to the world number three, and when the fourth set came to a tie-breaker, it was Djokovic who would hold his nerve.

"[Djokovic] is just really composed," Kyrgios said. "It's weird, I felt like he didn't do anything amazing today.

"He returned obviously the way he returns – I feel like he's just a great returner – but he was just so composed. I feel like that's his greatest strength: he just never looks rattled."

Not disheartened from falling just short of his first grand slam title, Kyrgios said he had taken plenty of confidence from his run to the final.

"My level is right there," he said. "I'm not behind the eight ball at all. 

"I played a slam final against one of the greatest of all time, and I was right there. [It gives me] confidence obviously.

"It was a hell of an occasion. People were probably expecting me to have something happen today. 

"But I came out in the first set and I looked like I was the one who had played in a lot of finals. I thought I dealt with the pressure pretty well."

Kyrgios has caused a stir at The All England Club over the past week, making headlines not only for his high-quality tennis, but his on-court behaviour.

The outspoken Australian is no stranger to arguing with umpires and line judges but has been particularly vitriolic at times at Wimbledon.

On Saturday he clashed with Tsitsipas, who subsequently accused the 27-year-old of being a "bully". Both players were fined for their conduct.

Now into the quarter-finals after beating Brandon Nakashima on Monday, Kyrgios has matched his best run at a grand slam, reaching the last eight at a major for the first time since 2015.

But former British number one Lloyd believes that stern calls from umpires are the way to keep a lid on Kyrgios' emotions.

Lloyd told Stats Perform: "I love watching Kyrgios because he is in some ways, it's almost like a [Roger] Federer, not in the personality, but the way he can conjure up shots that no one else can get.

"And plus, you never know what he's going to do with the drop, the underarm serves and various other things. That makes him a fun guy to watch. The game is looking for characters and I think we always say that [about Kyrgios].

"I have no problem with some of the stuff he does. But when it gets to the stage, which it was on Saturday, when it becomes a circus where it's all about him, there has to be a line there. 

"I think what happened was the umpire messed up. Something I can't understand is when you're umpiring Nick Kyrgios in a match as big as this, you have to put the best guy out there that won't stand for any stuff. In other words, you've got to set the standard from the beginning.

"[A line judge] came up to the umpire after the second or third game in the middle of the rally to say basically that he had sworn and the umpire sort of looked and then hesitated, didn't give him a warning. It was almost like he was thinking, 'I'll let this one slip.'

"Well, with certain players, you could let it slip. But with Nick, he should have come right down on him. So he should put out the setting to say this is not going to happen and he didn't do that, and after that, Nick just got all over him."

Lloyd also feels that world number five Tsitsipas, who was defeated 6-7 (2-7) 6-4 6-3 7-6 (9-7) allowed Kyrgios to get under his skin.

"Tsitsipas was the sideshow. He's just trying to play tennis, and he's not being allowed to because of the constant barrage of talking going on," Lloyd added.

"He's rushing him the whole time. That's Tsitsipas' fault in some ways. He could have slowed it down. He was trying to be professional.

"When he lost the second set, he exploded. Hit the ball into the crowd, it did hit someone off a rebound. He could have got defaulted there.

"But for me, it was Kyrgios that goaded him for the first couple of sets and he was allowed to basically control the way the match was going, and I think that's got to be stopped. It's okay to have a bit of entertainment here and there, but not to the stage where your opponent can't play properly because of all the stuff that's going on."

Kyrgios will face Cristian Garin for a place in the semi-finals. It will be the first quarter-final between two unseeded players at Wimbledon since Arnaud Clement took on Rainer Schuttler in 2008.

In some regards that proved true, with Kyrgios providing those in attendance and watching at home with a run-through of his greatest hits.

There was plenty of ranting from start to finish – some perhaps going too far – with the odd interaction with the crowd and a broken racquet or two thrown in for good measure.

In between all that, Australia's first finalist here since Mark Philippoussis in 2003 produced some remarkable shots, an underarm serve and brilliantly executed tweener included.

Love him or hate him, this was Kyrgios at his ill-tempered best, and he went a long way to showing there is more to him than just a petulant twentysomething by taking the first set.

At that point, Kyrgios had reeled off five sets in a row across three meetings with his opponent without dropping one. But this is Djokovic, on Centre Court, in a grand slam final.

 And so at the end of a three-hour battle, it was Djokovic who prevailed 4-6 6-3 6-4 7-6 (7-3) to make it 21 major titles, pulling him back to within one of Rafael Nadal's record.

It was the enforced withdrawal of Nadal that gave Kyrgios his route into the biggest match of his career, and thus denied the millions viewing around the world their dream final.

While witnessing tennis' two greatest ever players face off once more would have made for quite the spectacle, this was a Championship clash that provided subplots galore.

One of the themes of this year's tournament has been Djokovic's uncharacteristically slow starts, almost teasing opponents into thinking they had his number before striking back.

He trailed Jannik Sinner and Cameron Norrie in the past two rounds and so that proved again versus Kyrgios, who with those slow starts in mind let Djokovic serve first.

That appeared to be a masterstroke when Djokovic double-faulted first up, yet the Serbian recovered – as he so often does – to hold and settle into the match.

But Kyrgios went on to earn the only break of the first set in the fifth game and let out a huge roar of "Let's go!". If anything, that only worked to fire up his opponent even more.

This was hardly unchartered territory for Djokovic, who also lost the opener in last year's final against Matteo Berrettini before battling to victory in four sets.

The second set proved far more comfortable for the 35-year-old, promoting Kyrgios to take a different approach as he let loose at the umpire. It would not be the last time.

If Kyrgios stuck to his half of the bargain by being his usual self, Djokovic did likewise by focusing solely on his tennis and taking a well-contested third set with a solitary break.

As the lowest-ranked finalist in a grand slam final since Marcos Baghdatis (50) at the Australian Open in 2006, world number 40 Kyrgios surely knew his number was up.

And so it proved as for the 13th time in 15 grand slam matches when losing the opening set, it was Djokovic left celebrating as he claimed a seventh Wimbledon crown.

 This latest comeback also made Djokovic the first player since Ted Schroeder in 1949 to win the title after dropping the first set in the quarter-finals, semi-finals and final.

It will almost certainly not be the four-in-a-row champion's final title, either, though it remains to be seen if Kyrgios will scale these heights again any time soon – if at all.

On this occasion, Djokovic simply proved a step too far as Kyrgios' fireworks fizzled out at the climax of a fascinating Wimbledon campaign.

With both Murray and Kyrgios unseeded, they could have been drawn to face any of the top seeds, but it did not work out that way, most likely to everyone's satisfaction.

Instead, top seed and tournament favourite Djokovic drew South Korean Kwon Soon-woo, while Nadal was pitted with 23-year-old Argentinian Francisco Cerundolo.

Djokovic will be bidding for a seventh Wimbledon title and a fourth in succession following triumphs in 2018, 2019 and 2021, after the cancellation of the 2020 championships.

For second seed Nadal, who has won the Australian Open and French Open already this year to reach a record 22 men's grand slam singles titles, there is the possibility of a rare calendar Grand Slam.

He must carry off the title at Wimbledon for the first time since 2010 to stay in the hunt for that elusive clean sweep, last achieved in men's singles in 1969 by Rod Laver.

Murray, who like Nadal is a two-time former Wimbledon champion, was paired with James Duckworth of Australia and could face big-serving American John Isner in round two. Murray has been troubled by an abdominal strain in the past fortnight, and it remains to be seen whether the 35-year-old is in shape to be a contender.

Duckworth's countryman Kyrgios has been in fine form of late, reaching consecutive semi-finals in Houston, Stuttgart and Halle before he too suffered an abdominal twinge this week and withdrew from the Mallorca Championships. Kyrgios will start against Britain's Paul Jubb at Wimbledon.

A notable first-round clash saw three-time major winner Stan Wawrinka, in the draw on a wildcard, paired with Italian 10th seed Sinner, while Matteo Berrettini, runner-up to Djokovic last year, will play Chile's Cristian Garin.

Powerful Italian Berrettini, who has won the Stuttgart and Queen's Club titles on grass this year, features on Nadal's side of the draw, while in the top half Djokovic has the likes of Carlos Alcaraz and Hubert Hurkacz for company.

Alcaraz, the 19-year-old Spanish revelation who has won four titles already this year, was drawn to face the experienced German Jan-Lennard Struff in round one.

Men's third seed Casper Ruud has never won a singles match at Wimbledon, losing in the first round on his previous two appearances. The recent French Open runner-up will look to get off the mark on the SW19 grass against 34-year-old Spaniard Albert Ramos-Vinolas.

Centre Court played host to a match-up of contrasting experience, with Kyrgios playing his maiden major singles final in what was Djokovic's 32nd such showpiece – an Open Era record.

Djokovic ultimately held his nerve, taking a fourth straight title at the All England Club with a 4-6 6-3 6-4 7-6 (7-3) victory to move one behind Rafael Nadal's record 22 grand slam titles.

The Serbian also moved level with Pete Sampras in terms of Wimbledon triumphs, only one behind Roger Federer's eight.

 Kyrgios was offered a shot at the title after Nadal withdrew from their semi-final with injury, and he struck first with a break in the fifth game as a nervy Djokovic produced a double fault.

Djokovic continued to struggle to cope with the big-serving Kyrgios, who registered back-to-back aces to take the first set, in which he did not offer the Serbian a single break point.

But Djokovic soon regained his composure and finally broke Kyrgios for the first time in their third career meeting, before saving four break points in the ninth game to level the match.

Kyrgios, irked by a code violation for audible obscenities when displeased with a member of the crowd, then failed to hold his serve at 4-4 as frustrations grew, with Djokovic keeping his cool to secure the third set.

World number 40 Kyrgios rediscovered his serving rhythm to take the fourth set to a tie-break, yet he then made a series of unforced errors as Djokovic secured the title in SW19 once again.

Data slam: Djokovic's Wimbledon dominance continues

At 35 years and 49 days old, Djokovic became the second-oldest man to lift the Wimbledon title in the Open Era, and the Serbian's four consecutive successes at the All England Club only rank behind the five-win streaks of Bjorn Borg (1976-1980) and Federer (2003-2007).

Djokovic has also won 86 times at the London major, his best record in a single grand slam, with only Federer (105) winning more matches at Wimbledon.

Meanwhile, having lost the opening set in each of his past three matches, Djokovic became the first player in the Open Era to win the title at Wimbledon after dropping the first set in the quarter-final, semi-finals and final – and the first overall since Ted Schroeder in 1949.

WINNERS/UNFORCED ERRORS
Djokovic – 46/17
Kyrgios – 62/33

ACES/DOUBLE FAULTS
Djokovic – 15/7
Kyrgios – 30/7

BREAK POINTS WON
Djokovic – 2/4
Kyrgios – 1/6

Djokovic surpassed Roger Federer (31) for the most major finals among male players with his four-set victory over Cam Norrie in Friday's semi-final.

It means he will now face Kyrgios, who progressed without playing after Rafael Nadal withdrew from their last-four meeting due to an abdominal injury.

The six-time Wimbledon champion has never beaten Kyrgios, losing each of their previous meetings in Acapulco and Indian Wells in 2017 in straight sets.

Their third encounter could be one high on emotion. Djokovic appeared to blow kisses towards a heckler in the Centre Court crowd after defeating Norrie while Kyrgios, known for his on-court outbursts, was recently involved in an extremely tempestuous third-round clash with fourth seed Stefanos Tsitsipas.

"One thing's for sure, there's going to be a lot of fireworks emotionally from both [of us]," Djokovic said on court afterwards. 

"It's going to be his first grand slam final obviously he's very, very excited, he doesn't have much to lose and he's always playing like that.

"He's playing so freely, one of the biggest serves in the game, just big game overall, a lot of power in his shots.

"We haven't played for some time. I've never won a set off him so hopefully it can be different this time.

"It's another final for me here in Wimbledon with the tournament that I love so much so hopefully the experience can work in my favour."

Djokovic clinched his 21st grand slam win by recovering from one set down to beat Nick Kyrgios in Sunday's Wimbledon final, moving to within one major title of Rafael Nadal's record of 22.

On his 32nd grand slam final appearance – an Open Era record – the Serb claimed his fourth consecutive title at the All England Club with a 4-6 6-3 6-4 7-6 (7-3) victory in a tense encounter.

But it has not been plain sailing for Djokovic this year, who missed January's Australian Open after being deported over his refusal to be vaccinated against COVID-19, and was unable to enter the United States to play the Indian Wells Masters in March.

The United States still does not allow unvaccinated foreigners to enter the country without an exemption – meaning Djokovic's ability to appear in New York is in doubt.

But he is hopeful a change in policy could alter that state of affairs before the tournament gets underway on August 29, as he reiterated he would not get vaccinated and saw an exemption as unlikely. 

"It is a weird situation," Djokovic said. "I am on vacation. It has been quite an exhausting and demanding period for me. I got what I wanted here. 

"I'll wait hopefully for some good news [a change of policy] from the US. I'm not vaccinated and I'm not planning to get vaccinated. I don't think exemption is realistically possible.

"We'll have to see what the schedule looks like then. I doubt I'll chase points. Things have changed in the last year and a half for me. 

"I achieved the historic weeks of being ranked number one, that I worked for all my life. Now I prioritise slams and big tournaments where I feel good."

Djokovic's Wimbledon triumph comes at the end of a challenging few months, with the 35-year-old losing year's US Open final and exiting the 2022 French Open to Nadal either side of his much-publicised deportation from Australia. 

And the Serb, who claimed a first career win over Kyrgios on the biggest stage on Sunday, acknowledged: "This year has not been like last year.

"In the first several months of the year I was not at a good place mentally, emotionally. Everything that followed Australia has been a huge challenge and obstacle for me to overcome emotionally. 

"It wasn't that easy to close that chapter. It caused turbulence inside of me and I just had to weather the storm.

"I realised it would take time to regroup and rebalance. All these things off the court were causing so much distraction and pressure for me and the people around me. You can’t pretend it's not happening.

"By Rome and Paris I was already playing the tennis that I want to play. I liked my chances coming into Wimbledon. I think I managed everything pretty well today.

"Now I'm over the moon with joy and happiness of experiencing this moment once again. I don't take any wins for granted, and particularly not in Wimbledon. Every time feels special in its own way.

"Centre court and this tournament still has the most special place in my heart because it has always been my childhood dream tournament. Every time I step out on court it does not feel like anything else. I feel very connected with this court and this tournament. I'm very happy."

Kyrgios, appearing in his maiden major final and as the first Australian to make the Championship match at the All England Club since 2003, raced out the blocks to claim the first set.

Djokovic struggled to respond to the big-serving and heavy-hitting Kyrgios, but eventually broke for the first time in his third career meeting against the Australian to wrestle back some control.

As Djokovic grew into the game and manipulated his opponent around the court, Kyrgios became increasingly frustrated, arguing with both the umpires and one particular vociferous member of the crowd.

The world number three kept his cool, boasting a familiar aura of calmness, and ultimately triumphed 4-6 6-3 6-4 7-6 (7-3) despite Kyrgios rediscovering his formidable serving in the latter exchanges.

That moved Djokovic one grand slam title behind Rafael Nadal's record of 22 major successes, but much of his post-match focus was on Kyrgios, whose outbursts did not detract from the Serbian's admiration of his opponent.

"Nick, you'll be back. Not just in Wimbledon but in many finals," Djokovic said in his on-court interview.

"I really respect you a lot, you're a phenomenal player and athlete, you've been told that for many years.

"Everything is starting to come together for you and I'm sure we will see much more of you in the later stages of grand slams.

"I never thought I was going to say so many nice things about you considering our relationship – okay, it is officially a bromance!"

The pair had exchanged messages on social media in the build-up to the showpiece, promising to enjoy dinner with one another after the final, with the winner paying for the meal.

Djokovic joked, "Yeah, that's why he lost", when asked if he would foot the bill for the duo's evening in SW19 or further afield, before adding: "I'm sure this is the start of a wonderful relationship for us.

"Let's start with dinner and drinks and then we will see!"

Djokovic won the crown for a fourth straight time to claim a seventh title at the tournament overall as he moved level with Pete Sampras in terms of Wimbledon crowns, only one behind Roger Federer's eight.

The 35-year-old now has 86 wins at the London major, his best record in a single grand slam, with only Federer (105) winning more matches at Wimbledon, and Djokovic was quick to discuss how much the tournament means to him.

"I lost words for what this tournament and what this trophy means to me, to my coach, my family and my team. It always has been and will be the most special tournament in my heart," he added.

"It is the one that inspired me and motivated me to start playing tennis, when I was little at a mountain resort in Serbia and I saw Sampras win his first title in 1992, I asked my parents to buy me a racquet.

"And my first image in tennis was grass, and Wimbledon, and I always dreamed of coming here, then realising my childhood dream and winning here, every single time it gets more and more meaningful.

"I'm very blessed and very thankful to be standing here with the trophy."

The 27-year-old Australian was largely all business and no nonsense as he won 6-2 6-3 6-1 in one hour and 25 minutes against 26th seed Filip Krajinovic, delivering the kind of performance that underlines his potential threat at this tournament.

Yet Kyrgios had been far from his best against British player Paul Jubb in round one, eventually forcing victory by taking a tight fifth set, and his on-court behaviour came in for close scrutiny too in that match.

Against Jubb, a line judge was prompted to speak to the chair umpire about Kyrgios, whose demands for some fans to be removed were punctuated by spitting towards a section of the crowd upon victory.

Kyrgios spoke after that match of receiving "a lot of disrespect" from the crowds, while he also jousted with journalists in a news conference, before being angered by what he read afterwards.

Sinking Queen's Club runner-up Krajinovic in such a classy fashion was described by the unseeded Kyrgios as his response.

"I was pretty disappointed in my performance in the first round. Then obviously the media's disrespect and just everything, it was just kind of a reminder to put you all back in your place from the performance today," Kyrgios said. "He made finals at Queen's, top 30 in the world, seeded. It's a gentle reminder."

Kyrgios hit 50 winners and made only 10 unforced errors, saying in an on-court interview that he had displayed "great body language".

"I just wanted to remind everyone that I'm pretty good," he said, with a deliberately straight face.

"I'm just happy. I've been working hard and I've been preparing for this tournament. It's been circled on my calendar pretty much all year, and I'm so excited to be here again.

"I think it's my best chance to win a grand slam of all the four [majors], and I'll keep taking it match by match. I've got an incredibly tough draw still, and today I couldn't have played better and now I can just recover and get ready."

Awaiting Kyrgios in round three is Tsitsipas, a straight-sets winner on Thursday against another Australian, Jordan Thompson.

Kyrgios holds a 3-1 winning head-to-head advantage over Tsitsipas in their previous meetings, coming out on top when they met at Halle just a fortnight ago.

That recent match means Tsitsipas has it fresh in his mind what it might take to topple Kyrgios, and the Greek fourth seed told a news conference: "He claims to like grass and his game is good for the grass.

"I am thrilled to be facing him. I respect him a lot on the court and what he is trying to do. Even though he has been a little controversial in the past, I think he's playing good tennis.

"I'm going to concentrate on doing my own thing and pay attention to my own game from start to finish. Hopefully I can have a great competitive match against him."

The pair played out an ill-tempered third round encounter on Court One that saw the Australian come from behind to defeat the fourth seed in a 6-7 (2-7) 6-4 6-3 7-6 (9-7) win.

The pair traded furious remarks afterwards, with the Greek accusing his rival of having an "evil side", while Kyrgios called his opponent "soft" and suggested he is disliked by his fellow players.

Now, the duo have been handed financial penalties, with Kyrgios charged $4,000 (£3,300) for an audible obscenity and Tsitsipas slapped with a $10,000 (£8,250) fine for unsportsmanlike conduct.

It is the second fine of the tournament for Kyrgios, who was sanctioned for an incident in his opening clash with Britain's Paul Jubb.

The Australian - who experienced grand-slam glory on home soil in the men's doubles earlier this year - will now face Brandon Nakashima in a last-16 tie.

The 27-year-old defeated Jubb 3-6 6-1 7-5 6-7 (3-7) 7-5 and hit 67 winners but after a drama-filled three hours and five minutes, his prompting of a line judge to speak to the chair umpire and demands for some fans to be removed were punctuated by spitting towards a section of the crowd upon victory.

Earlier this month, tournament organisers in Stuttgart investigated when Kyrgios claimed he was racially abused by sections of the crowd during a match.

At his post-match news conference, Kyrgios jousted with journalists on the capacity of older line judges to make accurate calls, but primarily focused on the perceived normality of on and off-court abuse.

"A lot of disrespect was being thrown today from the crowds," he said. "I’m just starting to think that it’s normal when it’s really not.

"I didn’t say anything to the crowd until they started just every time I came down to the far end, people just going. It’s just I don’t know if it’s normal or not.

"Just pure disrespect, just anything. Someone just yelled out I was s**t in the crowd today. Is that normal? No. I just don’t understand why it’s happening over and over again.

"Have you ever gone to a supermarket and just started berating someone scanning the groceries? No. So why do they do it when I’m at Wimbledon? Why is that?"

In a testy news conference, Kyrgios was himself accused of lacking respect, but he lamented over not being able to respond to the abuse he receives on the court without some kind of punishment.

The world number 40 insisted he has no regrets on spitting towards an unruly fan after his win.

"Today, as soon as I won the match, I turned to him," Kyrgios said. "I’ve been dealing with hate and negativity for a long time, so I don’t feel like I owed that person anything.

"Like, he literally came to the match to literally just, like, not even support anyone really. It was more just to, like, stir up and disrespect. That’s fine. But if I give it back to you, then that’s just how it is.

"There’s a fence there and I physically can’t do anything or say anything because I’ll get in trouble. They’re able to say anything they want."

Kyrgios made headlines in the week with complaints over the condition of the grass courts at the All England Club, though the divisive Australian had looked sharp in wins over Ugo Humbert and Gianluca Mager.

He carried that form into his second career meeting with Canada's Auger-Aliassime, but as he charged to a 6-2 lead in the first set, Kyrgios sustained an apparent abdominal injury.

The 26-year-old received treatment on court, yet was clearly in distress as he attempted to continue, with Auger-Aliassime capitalising to take the second set 6-1 in just 22 minutes.

It signalled the end of the road for Kyrgios, who handed the win to the world number 19.

Despite his withdrawal, Kyrgios remained in good spirits.

Explaining his decision, Kyrgios said: "I haven't played this level of tennis in a long time, and obviously playing someone as good as Felix, my main weapon – my serve – to be firing on all cylinders and I just felt my abs, definitely did something in the first set.

"That's the way it goes. He's a hell of a player, he's going to do special things in this sport. Playing out here, having this support, has made me have a second wind. I reckon I'm going to come back and play for a bit longer.

"I did all I could to get here. I beat a heck of a player in the first round, played a great second round and just to get out here again, two sets, tried to play as long as I could, sorry I couldn't give you more today. But you'll see a lot of [Auger-Aliassime] in the future, and he's better looking too!"

For his part, Auger-Aliassime was equally as frustrated not to be able to see out what promised to be an entertaining match up.

"First of all, sorry for Nick, he was playing so good in the first set. It's really unfortunate in front of a packed crowd," he said.

"I think there were big expectations for this match, we were hoping to put on a good show, entertain the crowd, so it's unfortunate he had to retire. I hope it’s nothing too serious and he’ll be back on the US swing."

But following news of that semi-final walkover, the Australian was so excited he struggled to sleep.

Kyrgios, speaking to the media on Friday, said he learned of Nadal's withdrawal with an abdominal muscle tear only shortly before the Spaniard announced his decision at a news conference.

While Kyrgios – who enjoys a feisty rivalry with the 22-time grand slam champion – sent Nadal a message on Instagram, he was yet to speak to him.

The 27-year-old had been desperate to beat Nadal, but his respect for his opponent was also evident in his words.

"Honestly, my first feeling was a bit of disappointment," Kyrgios said.

"My energy was so focused on playing him and tactically how I'm going to go out there and play, the emotions of walking out there and all that type of stuff.

"It's not the way I wanted to get to the final. As a competitor, I really did want that match – it was obviously something, as soon as I beat Garin, that I knew Rafa was a high possibility.

"It's just someone that I've had so many good battles with before. We've both taken a win against each other at this tournament, and I really did want to see how the third chapter was going to go.

"You never want to see someone like that, [someone] so important to the sport go down with an injury like that. 

"He's just played so much tennis, he's had a gruelling season, so I just hope he recovers. I'm sure I'll play him again on a big stage."

He added: "But obviously it's exciting to say I'll have a chance to play for a grand slam singles title; after everything, it's pretty cool."

Indeed, so exciting Kyrgios endured "a shocking sleep" on Thursday night.

"I got probably an hour of sleep," he said. "Just with everything, the excitement, I had so much anxiety, I was already feeling so nervous – and I don't feel nervous usually."

Kyrgios was concerned the absence of a semi-final match would knock him out of what has been "a pretty good routine" in his run to a first major final.

"People will say, 'he gets another day off', but it's definitely a shock to the system, having been playing so many matches," he explained.

"You play a match at a grand slam and you know, deep down, that you have one day to wind down, let yourself relax and then go again.

"To have two and a half, three days off... today I'm going to emulate not a match scenario but I'm going to try to have a bit more of an extended practice to try to feel like I'm in that same routine.

"That can throw anyone off. At a grand slam, you want to have those matches, you want to have those competitive juices, you want to have those going, the adrenaline.

"That's just something I'm going to have to go into the final without, that semi-final experience.

"That's okay, I'm going to take the positives, rest my body a bit; it's not bad going in there feeling fresh."

The outspoken Kyrgios has made plenty of headlines so far at Wimbledon, and had to battle hard against 20-year-old American Nakashima on Centre Court on Monday, two days after his ill-tempered clash with Stefanos Tsitsipas.

That win over the world number five took four sets, but Kyrgios needed all five this time around, eventually prevailing 4-6 6-4 7-6 (7-2) 3-6 6-2.

The victory sent Kyrgios into the last eight at Wimbledon for the second time, after he reached the same stage by beating Rafael Nadal in 2014, while it is only the third time in the Australian's career that he has progressed to a grand slam quarter-final, having last done so in Melbourne in 2015.

It also kept up Kyrgios' 100 per cent record of winning Wimbledon matches that have gone to five sets, with the 27-year-old now 6-0 in that regard, with two of those victories coming at this year's edition of the major.

"First I want to say hell of an effort from Brandon, he's 20 years old and he's going to do some special things that's for sure," said Kyrgios, who needed medical attention on a shoulder injury during the tie, in his on-court interview.

"[It was] nowhere near my best performance, but I fought through, the crowd were amazing.

"I have played a lot of tennis in the last month and a half. His level didn't drop. My five-set level is pretty good and I've been here before, done it before and that is what I was thinking about."

The only disappointment from Kyrgios' point of view was missing out on an all-Australian quarter-final against Alex de Minaur, who squandered a two-set lead as he went down 2-6 5-7 7-6 (7-3) 6-4 7-6 (10-6) to Cristian Garin, who became the first Chilean player to reach the last eight of a grand slam since Fernando Gonzalez at the US Open in 2009.

Any nerves are nothing that a stiff drink will not fix for Kyrgios, however.

"I was really excited to play De Minaur to be honest, he's been flying the Aussie flag for so long and he was two sets up when I came on court," he said.

"I need a large glass of wine tonight for sure.

"I stepped out here amongst the greatest of all time and I beat Nadal [in 2014]. All these experiences that I've had got me over the line today."

Djokovic lost the opening set, as he did against Jannik Sinner in the quarter-finals and Cameron Norrie in the semi-finals, but recovered to claim a fourth-straight crown at SW19.

The top seed, who is now back to within one grand slam title of Rafael Nadal's Open Era record of 22, prevailed 4-6 6-3 6-4 7-6 (7-3) in a little over three hours.

And Kyrgios, handed a walkover win in his semi-final against Nadal after the Spaniard pulled out injured, led the tributes to Djokovic after his latest major triumph.

"He's a bit of a god, I'm not going to lie," he said in his on-court interview. "I thought that I played well, so I want to congratulate Novak and his team." 

Kyrgios was the first unseeded player to contest a grand slam final since Jo-Wilfried Tsonga at the 2008 Australian Open, having previously never made it beyond the final eight.

However, asked if he is hungry for more after his deepest run at a major, Kyrgios joked: "Absolutely not! I'm so tired. Me and my team are exhausted. We've played so much tennis.

"I'm really happy with this result and maybe one day I'll be here again but I don't know about that."

Kyrgios was his usual self on Centre Court, producing some remarkable shots – including an underarm serve – and regularly berating the umpires in equal measure.

However, the world number 40 – the lowest-ranked grand slam male finalist since Marcos Baghdatis (54) at the Australian Open in 2006 – extended a word of thanks to the officials.

"To all the ball kids and also the umpires – I know you and I have a tough relationship at times – but thank you," Kyrgios added.

The Australian was forced to come from behind to avoid a surprise exit, ultimately prevailing 3-6 6-1 7-5 6-7 (3-7) 7-5 on No.3 Court on Tuesday.

In a typically tempestuous performance, the world number 40 was frustrated by certain members of a partisan home crowd.

Kyrgios also accused a line judge of being a "snitch" as he aimed his grievances at the chair umpire, also calling for vocal spectators to be ejected.

The 27-year-old let his feelings be known after wrapping up his victory in just over three hours and paid tribute to his opponent.

"It was tough, he's a local wildcard, had nothing to lose and he played exceptional tennis at times," he stated. "He's going to be a good player for sure, I'm just happy to get through.

"The crowd was pretty rowdy. A couple of people were not shy in criticising me so that one is for you, you know who you are.

"Playing here is a lot of fun, Wimbledon over the last couple of years has been strange. We had bubbles last year and no ranking points this year, but it's special.

"It would've been a tough loss to take and I'm happy to get through. I just talk a lot on the court but off the court I'm not too bad."

Kyrgios will face either Serbia's Filip Krajinovic or the Czech Republic's Jiri Lehecka in the second round on Thursday.

Kyrgios recovered from one set down to post an impressive 6-7 (2-7) 6-4 6-3 7-6 (9-7) win over the fourth seed, setting up a last-16 tie with Brandon Nakashima with a scintillating performance on No. 1 Court.

But the contest was not without controversy, with Kyrgios frustrating Tsitsipas by calling for him to be defaulted after the Greek narrowly missed a spectator when firing a ball into the crowd at the end of the second set.

The Australian then labelled the umpire a "disgrace" during an extraordinary outburst, and his antics seemed to get under the skin of Tsitsipas, who was deducted a point for sending another ball towards the spectators before appearing to hit a couple of shots directly at Kyrgios.

While Kyrgios praised his opponent – with whom he played doubles at Wimbledon three years ago, as "a hell of a player" in his post-match interview, neither player was in the mood for niceties in their respective news conferences.

First up was Tsitsipas, who accused Kyrgios of "constant bullying".

"That's what he does," the world number five said of his rival. "He bullies the opponents. He was probably a bully at school himself.

"I don't like bullies. I don't like people that put other people down.

"He has some good traits in his character, as well. But he also has a very evil side to him, which, if it's exposed, it can really do a lot of harm and bad to the people around him."

Kyrgios, who has now claimed four wins in five career meetings with Tsitsipas, responded to that criticism shortly thereafter, alleging the Greek was not popular in the locker room and saying his inability to handle such matches would hold him back.

"He's that soft, to come in here and say I bullied him? That's just soft," Kyrgios said. 

"We're not cut from the same cloth. If he's affected by that today, then that’s what's holding him back, because someone can just do that and that's going to throw him off his game like that. I just think it's soft.

"I don't know what to say. I'm not sure how I bullied him.

"He was the one hitting balls at me, he was the one that hit a spectator, he was the one that smacked it out of the stadium.

"I didn't do anything. I was actually like… apart from me just going back and forth to the umpire for a bit, I did nothing towards Stefanos today that was disrespectful, I don't think. I was not drilling him with balls.

"I feel great, the circus was all him today. I think if he's making that match about me, he's got some serious issues, I'm good in the locker room, I've got many friends, I'm actually one of the most liked [players]. I'm set.

"He's not liked, let's just put that there. I'm good, I feel good."

Kyrgios is just one win away from matching his best run at Wimbledon, having reached the quarter-finals in 2014 with a win over Rafael Nadal before being beaten by Milos Raonic.

The Australian, a beaten quarter-finalist at Wimbledon in 2014 and 2015's Australian Open, dominated en route to a 6-4 6-3 7-6 (7-5) win in the tournament's first quarter-final between two unseeded players since 2008 (Arnaud Clement v Rainer Schuttler).

Kyrgios has courted controversy on multiple occasions over the last fortnight, spitting in the direction of a fan in the opening round before winning a bad-tempered clash with Stefanos Tsitsipas in round three, but he put the theatrics to one side in clinching a last-four spot on No. 1 Court.

Garin started strongly as he broke to love in the contest's opening game, but Kyrgios, energised after producing one of the shots of the tournament when stooping for a scarcely believable forehand winner, broke back shortly after.

After overcoming a back-and-forth ninth game to record another break, Kyrgios served the opener out to love before moving through the gears in the second, which he wrapped up in 38 minutes to extend his lead.

Kyrgios's fine serving allowed him to take control of the contest, with his 17 aces in the match moving him clear of John Isner (114) as the player with the most aces at Wimbledon this year (120).

The Australian lost his way for much of the third set, producing a series of unforced errors to give Garin hope, but the Chilean's failure to convert any of his last eight break points saw Kyrgios force a tie-break.

Kyrgios rediscovered his form in the breaker to see out the win, setting up a last-four meeting with either Taylor Fritz or Rafael Nadal.

Kyrgios' win ensured he became the first male Australian player to reach Wimbledon's semi-finals since Lleyton Hewitt in 2005.

Having being taken to five sets on two occasions in West London this year (by Paul Jubb and Brandon Nakashima), the 27-year-old enjoyed a more comfortable outing on Wednesday when extending the best major run of his career.

The Australian world number 45 has looked sharp on grass already this month, reaching semi-finals in Stuttgart and Halle, where his runs were ended by Andy Murray and Hubert Hurkacz respectively.

Kyrgios, who could play Queen's Club Championship runner-up Filip Krajinovic in round two at Wimbledon, expects to have only a small portion of support when he begins against 22-year-old Jubb.

That match is set for Tuesday, and Kyrgios believes he is playing well enough to win through comfortably, ahead of the more obvious tests of his game that lie ahead.

Renowned as an immensely talented firebrand, the 27-year-old would rather be remembered as a grand slam champion, but there are some major obstacles blocking his path to that objective.

"I've played top-10 players in the world this year and made them look pretty ordinary," he said.

That claim is not without merit, given Kyrgios beat Stefanos Tsitsipas in Halle, Andrey Rublev in Miami, and Casper Ruud in Indian Wells.

He is picking and choosing when he competes to allow himself plenty of time to spend with friends and family, and is determined to find a successful work-life balance.

"I know where my game's at," Kyrgios added. "I know if I'm confident and playing well, I'm able to light it up whenever I want. I've got to pick and choose, so when I play, I've got to make sure I'm having some good results and putting in my best effort.

"If I figured that out earlier in my career, maybe the narrative may have been different, but I'm proud to be where I am at the moment.

"I know if I'm serving well and playing well, I can beat anyone. I've beaten pretty much everyone in the draw before."

Kyrgios lost to Russian Daniil Medvedev in the second round of the Australian Open in January and is disappointed the world number one has been banned, along with all Russian and Belarusian players, from Wimbledon.

That position has been taken because of the Russian-led invasion of Ukraine, but Kyrgios said: "My honest opinion is I don't think it was a good idea to ban the Russian players.

"Medvedev is the best we have in our sport right now. I think whenever we have cameras on and a lot of people tuning in, you want a lot of our players to be on showcase for the sport to grow.

"I'm disappointed that they're not here. It's weird not seeing Medvedev here, because we all know what he's capable of."

Medvedev will be far away from SW19 when Kyrgios begins his campaign against Judd.

The 'bad boy' image has stuck to Kyrgios, and he has often not helped his cause, with a string of incidents of volatile behaviour in his past. He accepts the crowd will be siding with the underdog on Tuesday.

"I'm used to wearing that black hat, the villain-type role, and I've just got to embrace it," he continued.

"I'm going to go out there and just play my game. If you look at the results of the last couple of weeks, if I just stick to my guns, the results say I should win pretty easy. 

"But I know that's not going to be the case, so I've got to be focused."
