Novak Djokovic had predicted "fireworks" in Sunday's Wimbledon final with Nick Kyrgios, tennis' self-proclaimed bad boy and as combustible a sports star as they come.

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.

Novak Djokovic overcame a spirited Nick Kyrgios in four sets to claim his seventh Wimbledon title and 21st grand slam crown on Sunday.

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.

Nick Kyrgios and Novak Djokovic crossed paths on the practice courts and began making plans to party after Sunday's Wimbledon final, on an unconventional day of build-up to the trophy match.

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.

"There's definitely times when I hate this sport."

It is difficult to imagine Rafael Nadal, Roger Federer or Novak Djokovic coming out with such a line – but then Nick Kyrgios does not pretend to be comparable to any of those tennis greats.

Kyrgios' maiden major singles final appearance has come about due to unprecedented circumstances, with a tear to Nadal's abdominal muscle making his opponent the first to benefit from a walkover in a Wimbledon semi-final in the Open Era.

"It's not the way I wanted to get to the final," said Kyrgios in the same news conference on Friday.

But injuries are becoming increasingly commonplace for the 'Big Three' – already trimmed from a 'Big Four' due to the fitness woes endured by Kyrgios' great mate Andy Murray.

So, does the first-time finalist see an opportunity to step into that void at the forefront of the sport?

"No, no, I don't," Kyrgios replied. "I don't think anyone's able to fill those shoes."

He added with a grin: "If I ever win a grand slam trophy, please don't put the pressure on my to do another one."

This might be Kyrgios' first and only title run, but it is one he has waited a long time for.

"I saw some of the professionals walking around when I'd be a junior here, and I never thought that I'd be playing for the actual men's title," he said.

"It's the pinnacle of tennis. Once you're able to raise a grand slam trophy, it's like: what else is there to achieve?

"I never thought I'd be here, and I'm just super proud and ready to go. I'm going to give it my all and see what happens."

Australia has waited a long time, too. Aussies have won six Wimbledon men's singles titles but none since Lleyton Hewitt's sole success in 2002.

Their last finalist was Mark Philippoussis in 2003, beaten by Federer for his first championship. By Sunday, 6,944 days will have passed since an Australian man walked out for a singles final on Centre Court.

That sort of legacy does not appeal to Kyrgios, though, as he explained: "The greats of Australian tennis haven't been the nicest to me, and they haven't always been the most supportive – they haven't been supportive these two weeks."

Hewitt is an exception – the Davis Cup captain was briefly a hitting partner prior to the tournament – but Kyrgios considers himself "definitely the outcast of the Australian players".

"It's pretty sad," he said, describing his relationship with other Aussie greats as "weird". "They have a sick obsession with tearing me down. It sucks."

No, rather than bid to join those ranks, Kyrgios believes he is inspiring others like him.

"I grew up in Canberra, the courts I trained on were horrible, and now I'm here with the chance to play the Wimbledon final," he said.

"I think it's honestly an inspiration for any kid who's been 'outcasted' or been surrounded by negative headlines or negative clouds or been brought down from a lot of different angles.

"It's possible, it's still possible to achieve something quite special if you just believe in yourself. I never really lost belief in myself."

There have certainly been no shortage of negative headlines.

Kyrgios spat at a spectator earlier in the tournament; his epic third-round win over Stefanos Tsitsipas was one of the matches of the fortnight, but his typically brash approach to that encounter was not widely popular; and when he spoke of having already prepared tactics for Nadal – a previous foe – it was easy to wonder whether Kyrgios intended to outplay his opponent or simply get under his skin.

More seriously, this week started with Kyrgios being summoned to appear before a court in Canberra next month to face an allegation of common assault.

Those Australian greats would not be alone in responding to a Kyrgios victory unenthusiastically, even if the Centre Court crowd appear to have warmed to him.

No amount of noise will be new to Kyrgios, and while this is his first major singles final, a doubles title at the Australian Open provided some vital preparation for getting to this stage, too.

"I realised in Melbourne that it's a long time; it's a really long time in one place," Kyrgios said.

He was ready then for the rollercoaster of a grand slam run: "I beat Paul Jubb 7-5 in the fifth set in my first round, and now I'm in the Wimbledon final. You've just got to ride the waves, roll with the punches.

"In a grand slam, you just don't know; you could be four points away from losing the tournament and then 11 days later you're in the final."

There is undeniable excitement at the opportunity that lies ahead of Kyrgios, who considers himself "one of the most competitive people I've ever met".

But for once he will be able to see the bigger picture if Sunday's match does not go his way; Kyrgios is the first unseeded major finalist since Jo-Wilfried Tsonga at the 2008 Australian Open and the first unseeded Wimbledon finalist since Philippoussis.

"I just know whether I win or lose on Sunday, I'm going to be happy, because it's just such a great achievement that I never thought I'd be a part of – especially at 27," Kyrgios said.

"For me, I thought it was the later stages of my career; I just never thought that it would be right here that I'd have a chance."

Now he does have that chance, though, he is determined to give his all – something that has not always been a given with Kyrgios, his critics might suggest.

"Since I've been born, only eight people have won this title, only eight," he said. "I'm just going to give it my best shot."

Novak Djokovic told fans to "expect fireworks" when he faces Nick Kyrgios in his record-breaking 32nd grand slam final at Wimbledon on Sunday.

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."

Novak Djokovic is a win away from a seventh Wimbledon title after coming back from a set down to end Cameron Norrie's dream home run at the All England Club.

Norrie was looking to become the first British man to reach the final at the All England Club since Andy Murray's triumph in 2016.

He appeared to have Djokovic unsettled when he won the first set in startlingly comfortable fashion.

However, Djokovic, as he has done so often, recovered superbly to storm to a 2-6 6-3 6-2 6-4 victory and set up a final with Nick Kyrgios, who benefited from Rafael Nadal's withdrawal through injury.

The pair traded breaks in the first two games, but Norrie struck a key blow in the fifth game when Djokovic hit long off a low backhand from the Briton. Djokovic fired into the net two games later to hand Norrie a third break of a set he wrapped up with an ace despite two double faults.

Djokovic responded by placing Norrie under sustained pressure on serve and it told in the eighth game of the second when the ninth seed pushed a forehand long, and he did the same off the backhand side as the Serbian levelled the match.

Norrie ballooned a forehand long in the opening game of the third to give the break to Djokovic, who raced away in style thereafter.

An excellent return off a Norrie second serve gave Djokovic a break in the first game of the fourth and he would not be prevented from reaching the finish line despite the home hope's spirited effort.

Data Slam: Djokovic's resilience shines through again

Djokovic has now won 12 of his last 14 grand slam matches after losing the first set. The only exceptions in that run came in the 2021 US Open final defeat to Daniil Medvedev and in the French Open quarter-final loss to Nadal this year.

With neither of those opponents in his way, Djokovic will be expected to claim a 21st grand slam title with triumph over Kyrgios.

Nick Kyrgios revealed he was disappointed to be gifted a place in the Wimbledon final, having been determined to earn his shot at the title by beating Rafael Nadal.

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."

Nick Kyrgios has taken to social media to wish Rafael Nadal a speedy recovery after the Spaniard withdrew from the pair's Wimbledon semi-final through injury.

Nadal appeared to be struggling throughout his epic five-set quarter-final win over Taylor Fritz on Wednesday, and it was later confirmed the 22-time grand slam champion had suffered a seven-millimetre abdominal tear.

The two-time Wimbledon champion then announced his withdrawal from the competition at a news conference on Thursday, saying he doubted his ability to win two matches while enduring the pain.

Nadal's exit means Kyrgios will become Australia's first male Wimbledon finalist since Mark Philippoussis in 2003, and is the first player to receive a semi-final walkover in the competition in the Open Era.

The enigmatic 27-year-old has since taken to Instagram to wish the Spaniard well, writing: "Different players, different personalities.

"I hope your recovery goes well and we all hope to see you healthy soon. 'Till next time…"

The Australian has enjoyed a heated rivalry with Nadal since beating him in their first head-to-head meeting at Wimbledon in 2014, with the pair engaging in a couple of high-profile spats.

Kyrgios will now face either Novak Djokovic or Cameron Norrie in Sunday's final, as he bids to become the first Australian man to win Wimbledon since Lleyton Hewitt defeated David Nalbandian in 2002.

He has embarked on a box-office run in SW19, coming through five-set thrillers against Paul Jubb and Brandon Nakashima, as well as winning a fiery third-round contest against Stefanos Tsitsipas.

Some 6,944 days will have passed since an Australian man played in a Wimbledon final by the time Kyrgios takes to Centre Court on Sunday, though he will look to fare better than Philippoussis did in 2003's straight-sets loss to Roger Federer.

World number 40 Kyrgios is also the lowest-ranked – and the first unseeded – Wimbledon finalist since Philippoussis (number 48), as well as the lowest-ranked grand slam finalist since Marcos Baghdatis (number 54) at the 2006 Australian Open.

Rafael Nadal says prolonging his career is more important than any trophy after withdrawing from Wimbledon ahead of his semi-final against Nick Kyrgios due to injury.

The second seed played though the pain barrier in beating Taylor Fritz in a five-set thriller in Wednesday's quarter-final, but he later admitted he was unsure if a troublesome abdominal issue would clear up in time for Friday's semi-final.

Nadal appeared on the practice courts on Thursday, despite tests reportedly revealing he had a seven-millimetre abdominal tear, though it ultimately proved in vain as he announced at a news conference later in the day that his match with Kyrgios would not go ahead.

While disappointed at being denied the chance of winning a first calendar Grand Slam, having already won the Australian Open and French Open this year, the 22-time major winner feels he had no choice.

"Unfortunately, as you can imagine, I am here because I have to pull out from the tournament," he said. "As everyone saw yesterday, I have been suffering with a pain in the abdominal [area] and something was not okay there. 

"That is confirmed, I have a tear in the muscle and the communication is too late. I was thinking the whole day, I was thinking about the decision to make, but I think it doesn't make sense to go, even if I try through my career to keep going. 

"It is very tough circumstances but it is obvious if I keep going the injury will be worse and worse. I never thought about the calendar slam, I thought about my diary and my happiness.

"I don't want to go out there and not be competitive enough to play at my best. The most important thing to me is happiness over a title."

Nadal showed incredible mental and physical resilience to dig deep and see off first-time grand slam quarter-finalist Fritz 3-6 7-5 3-6 7-5 7-6 (10-4), despite being a set down when calling for a medical time-out on Centre Court.

"I make this decision because I don't believe I can win two matches under the circumstances. It is not only I can't serve at the right speed, it is I can't do the normal movement to serve," Nadal added of his decision to pull out.

"After that, to imagine myself winning two matches and for respect for myself in some way, I don't want to go out there and not be competitive enough to play at the level I need to play to achieve my goals."

Kyrgios will now receive a bye through to a first grand slam final, where either Cameron Norrie or Novak Djokovic await on Sunday.

As for Nadal, he is hopeful of returning to action within "two-to-three weeks", meaning he will have time to get back up to speed in time for the US Open, which begins on August 29.

"My goal is to go to the Montreal Masters [on August 5]," Nadal said. "Injuries are part of my career. I saw myself with options to win the title, but you have to accept things as they come."

Rafael Nadal has been forced to withdraw from Friday's Wimbledon semi-final against Nick Kyrgios, ending his hopes of a first calendar Grand Slam.

Nadal played through the pain barrier in a mammoth four-hour quarter-final clash with Taylor Fritz on Wednesday, regularly being checked over by his physio during a 3-6 7-5 3-6 7-5 7-6 (10-4) win on Centre Court.

The Australian Open and French Open champion admitted in the aftermath of that success he was "worried" about the prospect of having to withdraw from the tournament, adding: "I don't know [if I will be able to play] – I am going to have some more tests, but it is difficult to know."

Nadal appeared on the practice courts on Thursday in a bid to find a way of competing but was unable to serve at full power, and reports said tests had revealed a 7mm abdominal tear.

The 36-year-old's efforts were ultimately in vain as he confirmed he was pulling out at a news conference later on Thursday, meaning Kyrgios advances to a first major final.

Cameron Norrie can thrive as an underdog against Novak Djokovic and cause a sensation in Friday's Wimbledon semi-final, according to a former coach of the British star.

Ninth seed Norrie has battled through to a showdown with 20-time grand slam winner Djokovic, who had to come from two sets adrift to beat Jannik Sinner at the last-eight stage.

Their clash will be first on Centre Court on Friday, with Norrie bidding to follow in the recent footsteps of Andy Murray, Britain's last men's singles champion at the All England Club.

Djokovic is riding a 26-match unbeaten run at Wimbledon into the match, as the top seed bids to move a step closer to a fourth consecutive title at the tournament.

Yet the lower-ranked man can win, and he could even do it with a set to spare, according to Mexican David Roditi, head coach of the Texas Christian University's tennis team, with whom Norrie honed his talent as a youngster.

As well as studying sociology, Norrie's sports scholarship centred on playing for the Horned Frogs team. He spent three years at the university before leaving in 2017 to embark on a professional tennis career.

Roditi told Stats Perform he expects Norrie to thrive after his battling five-set win over David Goffin last time out.

"Obviously it's not easy to make Djokovic uncomfortable, not easy to beat him on grass," Roditi said. "What I will say is that this is finally the first time that Cameron gets to play as an underdog.

"I'm hoping that he's able to loosen up a little bit, be a little bit more aggressive, be able to go after him a little bit more than he was able to in the quarter-finals.

"I could feel he was not comfortable during that match [against Goffin]. He knew it was a great opportunity. So that underdog mentality has usually worked out well for Cameron. And I'm hoping that that's exactly what happens. And then once you get into the physicality of the game, and I think the longer this match goes, the better chances are for Cameron."

Looking at a prediction for the contest, Roditi said: "Oh, Cameron, it's got to be all Cameron. It's got to be him. So I'm saying Cameron in four sets? Wow. We'll give Djokovic a set. And well, then Cameron can win in four sets."

Roditi said there was "so much pride and so much excitement" being felt in Fort Worth at seeing Norrie grow into an elite performer on the world stage.

The 26-year-old won the Indian Wells Masters last year, the biggest achievement of his career until this fortnight.

Roditi says he always saw world-class potential in Norrie.

"There's no doubt he was head and shoulders above your typical 18-year-old coming in: extremely competitive, always willing to do the extra work physically," Roditi said. "He would go for long runs on his own, and so his endurance level is tremendous. It's great for him and his five-set matches – that showed in the quarter-finals.

"What I will say is that there was nothing he couldn't accomplish, [nothing] that we would ever be shocked or surprised [by]. He's always been able to defeat the odds and do more than anybody would expect of him.

"It's scary to think about what would happen if he wins this match. I think at this point anything's possible."

Rafael Nadal faced make-or-break tests on Thursday to determine whether he would have to abandon his Wimbledon campaign.

The 22-time grand slam winner aggravated an abdominal injury during his five-set victory over Taylor Fritz in the quarter-finals, admitting he had been in pain on court.

It did not prevent Nadal lasting the distance in a stirring battle lasting four hours and 21 minutes, taking the decider on a tie-break.

But Nadal risks having to pull out of Friday's semi-final against Australian Nick Kyrgios if his body is judged to have taken too much of a battering.

Family members appealed to Nadal to give up the ghost against Fritz, but the 36-year-old played on and pulled off a typically gutsy victory.

He confirmed after the match: "Tomorrow I'm going to have some more tests. But [it is] difficult to know. It's obvious that I am a player who had a lot of things in my tennis career, so I am used to have things and I am used to hold pain and to play with problems.

"Knowing that, when I feel something like I felt, that is because something is not going the proper way in abdominal. But let's see. I had these feelings for a couple of days."

Nadal said it was undoubtedly "the worst day" for his abdomen since he first felt a strain, which had required strapping before he played Fritz.

He said there had "been an important increase of pain and limitation", but Italian player Fabio Fognini appeared to question Nadal's injury status when he posted a message in an Instagram story, reacting to a report pointing out the Spaniard's problem.

The message read: "For sure... Guys stop believe in what you read PLEASE."

But Fognini later denied that meant he was questioning Nadal's injury, accusing journalists of twisting his words.

He wrote: "It's time to stop writing and reporting everything that you want in the wrong way. With that I wish Rafa and his entire team a lot of good luck in this Wimbledon final."

Former Spain goalkeeper Santiago Canizares, who now works in the sports media, also weighed in, writing on Twitter: "If there is anyone to believe in this society, it is @RafaelNadal. For many reasons that I am too lazy to cite.

"There are those who doubt his injury yesterday, but one fact does not bear debate: his serve was 30 per cent less than his usual speed ... Usual almost 200 km/h. Yesterday 150/160 km/h"

That did not quite stack up across the entire match, but Nadal's average serve speeds (107mph for first serve, 95mph for second serve) were his slowest of the tournament so far.

Nadal has already won the Australian Open and French Open titles this year, defying a long-time foot problem. Should he play on and win Wimbledon, he would go to the US Open in August with a chance of achieving the first men's singles calendar Grand Slam clean sweep since Rod Laver achieved the feat in 1969.

The winner of the semi-final between Nadal and Kyrgios, should it go ahead as planned, will face the winner of Novak Djokovic's match against Cameron Norrie in the title match.

Rafael Nadal says he does not know if he will be able to play in his semi-final against Nick Kyrgios after aggravating an abdominal injury during his five-set victory over Taylor Fritz.

Nadal, 36, has been vocal about his struggles physically during the tournament, but had been determined to push through the pain in an effort to keep his chances at the calendar slam alive, having already won this year's Australian Open and French Open.

During his quarter-final win against Fritz, family members were imploring Nadal to retire from the match as his clear discomfort appeared to be getting the better of him at times.

He admitted in his post-match media appearance that his condition worsened during the match, saying he will prioritise his health if he has to make a tough decision.

"I don't know [if I will be able to play] – I am going to have some more tests, but it is difficult to know," he said.

"I had these feelings for a couple of days, but without a doubt, today was the worst day. There has been an important increase of pain and limitation.

"I am worried. I don't have a decision. I need to know different opinions and I need to check everything the proper way.

"There is something more important than winning Wimbledon, and that is health."

The winner between Nadal and Kyrgios will face the winner of Novak Djokovic's semi-final against Cameron Norrie in the decider.

Rafael Nadal is hopeful he will overcome an abdominal injury that plagued him during his victory over Taylor Fritz in time for Friday's Wimbledon semi-final against Nick Kyrgios.

The 22-time grand slam winner recovered from behind to edge Fritz 3-6 7-5 3-6 7-5 7-6 (10-4) in a thrilling contest on Centre Court on Wednesday.

Nadal called for a medical time-out in the second set and never fully recovered from the issue, with his movement restricted throughout the four-hour-and-20-minute battle.

However, Nadal showed incredible mental and physical resilience to dig deep and see off first-time grand slam quarter-finalist Fritz and set up a showdown with Kyrgios.

Speaking in his on-court interview, the Spaniard admitted he was not entirely sure he would be able to see out his quarter-final tie after playing through the pain barrier.

"The body in general is fine," he said. "The abdominal [area] is not going well. I had to find a way to serve a little bit different.

"For a lot of moments I was thinking I will not be able to finish the match, but the court energy was something else.

"I honestly enjoy a lot playing these kind of matches, in front of you guys, I can’t thank you enough. It has been a tough afternoon. [Fritz] is a great player, all the credit to him.

"He's been great the whole season. But from my personal side it was not an easy match at all, so I'm just very happy to be in the semi-final.

"I hope to be ready to play it. Nick is a great player on all surfaces but especially on grass, he is having a great grass-court season.

"It's going to be a big challenge and I'm going to need to be at my 100 per cent to have a chance, and that is what I'm going to try to do."

Nadal has now won all eight quarter-finals contested at Wimbledon and is on a 19-match winning run at grand slams – three short of his own record of 21, which he set in 2010.

The victory over Fritz marked only the second time Nadal has won a fifth-set tie-break at a major, having previously prevailed against Dominic Thiem at the 2018 US Open.

It was also the first time since the same stage four years ago, against Juan Martin Del Potro, that Nadal has come through a five-set match at Wimbledon.

He has two days to recover ahead of facing Kyrgios, who had earlier defeated Cristian Garin in straight sets to reach a first grand slam semi-final.

"Tomorrow I'm going to have some more tests. But it's difficult to know [how I'll feel]," Nadal said when providing a further update on his fitness.

"It's obvious that I am not the kind of player that I didn't have a lot of things [injuries] in my tennis career, so I am used to have things and I am used to hold pain and to play with problems.

"Knowing that, when I feel something like I felt, that is because something is not going the proper way. But let's see. 

"It's obvious that today is nothing new. I had these feelings for a couple of days. Without a doubt, today was the worst day.

"There has been an important increase of pain and limitation. I managed to win that match. Let's see what's going on tomorrow."

Nadal leads Kyrgios 6-3 in their previous nine career matches, including victories in two of their three meetings in majors.
