Tennis will never see a "big three" with the quality of Rafael Nadal, Novak Djokovic and Roger Federer again, believes Juan Martin del Potro.

The trio, who have combined for a total of 64 men's singles grand slam titles across a near-two-decade-long period of dominance, have come to define the sport's modern era.

Federer retired last year and while Nadal and Djokovic continue, both are well into the twilight of their careers, despite astonished continued success.

Del Potro, the 2009 US Open winner, also retired in 2022, and he thinks the trio's dominance is unlikely to be replicated going forward, even though he sees Carlos Alcaraz, Jannik Sinner and Holger Rune as three players who could possibly go on to enjoy great success.

"The only thing I lacked was being number one [in the ATP Rankings]," he said. "It was always a dream, and I always worked for it. I never made it because there was either Federer, or Nadal, or Djokovic.

"When I look at the rankings and the years of my career and who was fighting to be number one I see that it was beautiful that these were the ones who didn't let me make it, this dream."

"One day, the big three will end. We have Carlos Alcaraz, Jannik Sinner [and] Holger Rune, other young people who will mark the circuit.

"But for me, [for] many years, [it was] the big three. There will not be anything similar."

Del Potro reached a career high-mark of third in the ATP Rankings in 2018, with Andy Murray the only man other than Nadal, Federer or Djokovic to top the charts between 2005 and 2021.

Goran Ivanisevic says Novak Djokovic has not given up hope of competing at the Miami Open this month.

The 22-time grand slam champion withdrew from Indian Wells on Monday as he is unable to play in the United States.

As he is not vaccinated against COVID-19, Djokovic had applied for special permission to enter the USA, but was not given the green light.

While the 35-year-old is in the draw for the Miami Open, he may have to withdraw again despite the United States Tennis Association and US Open expressing their hope he would be allowed to feature.

Djokovic wants to play in a tournament that starts on March 22, his coach Ivanisevic confirmed, and pressed for a swift decision on the issue.

"We haven't given up. He wants to play and I would love it if they allow him – it would be great both for him and for tennis," he told Tennis Majors.

"If not, it's not the end of the world, he didn’t play last year as well. The most important thing is that we find out soon, so that we can make a plan.

"Although, in terms of preparing for the European clay court season, I'm not sure playing in Miami is the best solution. It depends on Novak – in the past he has triumphed in Monte Carlo having played in Indian Wells and Miami.

"If he is mentally ready and in his fighter mode, like he was in Australia, then anything is possible."

Ron DeSantis, the governor of Florida, has appealed to United States President Joe Biden to overturn a ban which will see Novak Djokovic miss this month's Indian Wells and Miami Open tournaments. 

The world number one remains unvaccinated against Covid-19 and submitted a request for special permission to play in the two ATP Masters 1000 events in the US, with Miami set to start in under two weeks. 

However, the Serbian has already been forced to withdraw from Indian Wells after his request was denied by American officials. 

The US is expected to lift its ban on unvaccinated travellers in May but, in a letter to Biden on Tuesday, DeSantis urged them to reconsider their ban on Djokovic ahead of the Miami Open in his state.

"This denial is unfair, unscientific and unacceptable," DeSantis wrote in the letter, which he posted on social media. 

"The only thing keeping Mr Djokovic from participating in this tournament is your administration's continued enforcement of a misguided, unscientific, and out-of-date Covid-19 vaccination requirement for foreign guests. 

"I urge you to reconsider. It's time to put pandemic politics aside and give the American people what they want - let him play." 

Florida senator Marco Rubio and Indian Wells tournament director Tommy Haas are two other figures who have also expressed their desire to see the ban overturned. 

Djokovic has been involved in regular controversies as a result of his Covid-19 vaccine stance, previously stating he would be willing to forgo grand slam opportunities rather than have the vaccination. 

The 22-time grand slam champion missed the Australian Open last year after being deported over the issue but returned in January 2023 to win his 10th title in Melbourne, defeating Stefanos Tsitsipas in the final. 

Djokovic has not competed in either the Indian Wells or Miami Open since 2019. He has won Indian Wells on five occasions and is a record six-time winner in Miami.

DeSantis has been tipped a potential Republican presidential candidate who could take on Biden at the 2024 election if he can beat Donald Trump to his party's nomination.

Novak Djokovic's absence from the Indian Wells Open has caused a stir in US politics, and on the tennis court it is hugely significant, too.

Sport was given a jolt three years ago when Indian Wells organisers cancelled the event on the eve of action getting under way, citing one local case of COVID-19.

At that point, on March 8, 2020, there had been more than 500 confirmed cases across the United States, with 21 deaths. Soon enough, events across the globe were being postponed or scrubbed.

Coronavirus travel restrictions prevented the unvaccinated Djokovic from taking part last year, and they will keep him away again this time, despite calls from two Florida senators for the jab requirement to be lifted by President Biden to allow the Serbian into the country.

With the world number one sidelined, Daniil Medvedev and Carlos Alcaraz look likely challengers for the men's title. There have been surprise champions in recent times, with Cameron Norrie winning in 2021 and Taylor Fritz carrying off the title 12 months ago, so it would be hasty to rule out something similar.

In the women's event, there has not been a successful title defence since Martina Navratilova won in 1990 and 1991. That can partly be attributed to Serena and Venus Williams boycotting for over a decade at the peak of their powers after complaining of facing racial abuse, and in their absence no player stepped up to dominate.

Iga Swiatek triumphed in Indian Wells and Miami last season, racking up the 'Sunshine Double', and she starts as a strong favourite again, but defeat in the recent Dubai final to Barbora Krejcikova showed the 21-year-old rankings leader will not have everything her way this season.

First-round action gets under way on Wednesday, after two days of qualifying, and here Stats Perform, with Opta data, looks at what lies ahead.

After Norrie and Fritz, could there be another shock men's winner?

Djokovic has won a joint-record five Indian Wells titles, but he last featured in 2019, when he lost to Philipp Kohlschreiber in round three.

Rafael Nadal is also absent this time with a hip injury, and with Roger Federer retired this will be the second Indian Wells main draw since 2000, after 2021, to feature none of the ATP Big Three.

The Big Three was a Big Four at one point, though, and Andy Murray will be competing. It is one of the two Masters 1000 tournaments Murray has never won, along with Monte Carlo, having triumphed at the other seven. Murray has the most match wins at Indian Wells among all men competing this time, having 28 to his name, two more than John Isner who sits next on the list.

No ATP player has a better win percentage at Indian Wells than Djokovic (84.7 per cent), who has won 50 of his 59 matches, while the now-retired Federer has appeared in the most finals (nine), also winning five times, so there is no doubt the field is missing its long-time classiest acts.

Fritz last year became the first men's champion aged under 25 years old since Djokovic in 2011, and he was also the first American to take the men's title since Andre Agassi beat Pete Sampras in the 2001 final.

Medvedev has won three consecutive tournaments in the lead-up this year, tearing to titles in Rotterdam, Doha and Dubai, but the Russian has a disappointing record at Indian Wells, having yet to reach the quarter-finals in five visits.

Just four players this century, including Alcaraz last year, have reached the semi-final stage before turning 20, with Nadal, Djokovic and Murray the other three. Alcaraz is still only 19 but a shade older than Boris Becker when he was a 19-year-old champion in 1987, the youngest men's winner.

Who else might come through? It feels like a free-for-all and Felix Auger-Aliassime will be hoping for a breakthrough tournament, with the Canadian being the only member of the current ATP top 10 to have never reached a final at ATP 1000 level. It has to happen sooner rather than later, surely.

Swiatek bids to lift curse of women's champions

Ever since Navratilova's two in a row, being a back-to-back champion at Indian Wells has been beyond all singles players on the WTA side.

Indeed, the only players to reach the final the year after their title run have been Lindsay Davenport (champion 1997, runner-up 1998) and Ana Ivanovic (champion 2008, runner-up 2009).

Nine women have won twice at Indian Wells, but none have managed three or more titles. The nine are: Steffi Graf, Mary Joe Fernandez, Navratilova, Daniela Hantuchova, Serena Williams, Kim Clijsters, Victoria Azarenka, Davenport and Maria Sharapova.

A Swiatek victory would make it a club of 10, but there is a club of one when it comes to players who have captured two titles without dropping a set in either trophy run. Sharapova is the only player to pull off that feat, with her 2006 and 2013 glory runs.

Among all women, Davenport has reached the most finals (six) and won the most matches (47), with Azarenka having the most wins among active WTA players (34).

Navratilova remains the oldest champion, having won aged 34 in 1991, while Martina Hingis and Serena Williams won as 17-year-olds in 1998 and 1999.

Shocks can happen: Bianca Andreescu took the title as a wildcard in 2019, while Jenny Byrne reached the final as a qualifier in 1989, the first year the women's event was staged.

If there is to be a teenage women's finalist this time, maybe it will be Coco Gauff. The American turns 19 midway through the tournament, on March 13, and has yet to reach a WTA 1000 final, although she got to the French Open title match last year, where Swiatek inflicted a heavy defeat.

Perhaps Aryna Sabalenka can reprise her Australian Open form, having won a first major in Melbourne. But Sabalenka's record in Indian Wells is a rough one, with the Belarusian yet to go past the fourth round.

Strap in for a thrill ride. They all want to stop Swiatek, but if any player can defy history it might just be the Pole.

Novak Djokovic will not feature at the Indian Wells Open.

It was confirmed by tournament organisers on Sunday that the world number one would miss the first Masters 1000 tournament of the season.

As he is not vaccinated against COVID-19, Djokovic had applied for special permission to enter the United States, but that has seemingly been denied.

Until at least April 10, international visitors to the US must have proof of vaccination.

Djokovic, a five-time winner at Indian Wells, is also set to miss the Miami Open later in March, while his participation in the US Open could be in doubt.

The 22-time grand slam champion – who reached the semi-finals at the Dubai Tennis Championships last week – missed last year's major at Flushing Meadows due to his vaccination status. He was, however, allowed to play in this season's Australian Open.

Nikoloz Basilashvili moved into the main field following Djokovic's withdrawal.

Novak Djokovic was waiting on Saturday to learn whether he would get last-minute clearance to enter the United States to play at Indian Wells and Miami, as American tennis chiefs threw support behind the world number one.

US senator Rick Scott claimed Djokovic has been refused permission by the US Department of Homeland Security for a vaccine waiver and urged president Joe Biden to intervene on behalf of the Serbian and "fix this NOW".

Scott was backed by fellow senator Marco Rubio, who wrote on Twitter: "@DjokerNole [Djokovic] shouldn’t be prohibited from playing in the @MiamiOpen because of unconstitutional vaccine mandates.

"@POTUS [Biden] should immediately grant Djokovic a waiver to the vaccine mandate for international travellers."

Djokovic has refused to be vaccinated against COVID-19 and that stance has cost him places in two grand slam tournaments, being deported before last year's Australian Open and then denied permission to compete at the US Open later in the season.

It has also meant he has had to miss regular tour events in the United States, which demands international travellers are fully vaccinated.

Scott and Rubio are both senators for Florida, and accordingly their focus is on the Miami Open, which runs from March 22 to April 2.

More pressingly for the 35-year-old Djokovic, the Indian Wells tournament begins in the coming week, with main draw singles matches getting under way on Wednesday.

A statement posted on the US Open Twitter page confirmed support for the 22-time grand slam winner.

It read: "Novak Djokovic is one [of] the greatest champions our sport has ever seen.

"The USTA and US Open are hopeful that Novak is successful in his petition to enter the country, and that the fans will be able to see him back in action at Indian Wells and Miami."

Daniil Medvedev denied Novak Djokovic a 21st consecutive win to set up an all-Russian final against Andrey Rublev at the Dubai Tennis Championships.

Djokovic had started 2023 by coming out on top in all 15 of his matches and winning the Australian Open, with his overall winning streak standing at 20 games.

But Medvedev ended the world number one's perfect start to the year with a superb display to take a 6-4 6-4 triumph on Friday.

The 27-year-old, who himself made it 13 consecutive wins, broke Djokovic twice on the way to taking the opening set.

Medvedev's high standard of play continued in the second, breaking Djokovic in the first game before holding in all five of his service games to secure a straight-sets victory.

"When you play against Novak you just have to play your best," Medvedev said after the win. "Kind of hope he doesn't play his best on the day because when he plays his best, well he has 22 grand slams, so even if you play your best, it is going to be tough, not sure you win.

"I managed to play a higher level than him today. In the second set I didn't face one break point, but there were so many 30-30 games. But I managed to stay composed and I am happy to be in the final tomorrow."

His win means he will face countryman Rublev in the final after the reigning champion kept his hopes of retaining the title alive with a 6-3 7-6 (11-9) success over Alexander Zverev.

Rublev had never previously won a match or set against Zverev in five previous meetings, but won three of the German's service games in the opener to go a set ahead.

The second seed was out-aced nine to two in the second set but managed to force a tie-break, going on to survive a set point before eventually securing the win on his sixth match point.

Rublev will look to join Roger Federer and Djokovic as only the third repeat champion at the tournament when he takes on Medvedev in Saturday's final.

The compatriots have met six times previously with Medvedev winning four of them, though Rublev has taken victory in their last two match-ups.

Novak Djokovic clinched a 20th win in a row and maintained his perfect year to date with victory against Hubert Hurkacz at the Dubai Tennis Championships.

The world number one cruised in the opening set, before Hurkacz put up more of a fight in the second.

Djokovic eventually prevailed to seal a 6-3 7-5 win, successfully seeing off his opponent despite Hurkacz valiantly throwing everything at him.

The 35-year-old Serbian has now won 15 consecutive matches in 2023, with his latest impressive display including just seven unforced errors, less than half Hurkacz's 15 as Djokovic's clinical edge proved decisive.

Fifteen successive victories is the fourth-best start to a season in Djokovic's career, though he remains some way off the 41-0 record he began 2011 with.

A semi-final clash against Daniil Medvedev awaits following the Russian's comfortable 6-3 6-2 victory against Borna Coric, which clocked in at one hour and 21 minutes.

Medvedev is also in the midst of an impressive winning streak, rattling off 12 consecutive successes since being eliminated by Sebastian Korda at the Australian Open in January.

Andrey Rublev booked his spot in the final four with a 6-3 7-6 (7-3) victory over Botic van de Zandschulp to maintain his title defence.

He will face seventh seed Alexander Zverev in the semi-final, the German having seen off Lorenzo Sonego 7-5 6-4.

Novak Djokovic swept through to the quarter-finals of the Dubai Tennis Championships with ease on Wednesday, clinching a 6-2 6-3 win over Tallon Griekspoor.

The Serbian picked up his 19th consecutive victory midway through his record 378th week as world number one, settling his last-16 clash in straight sets.

Griekspoor, at a career-high position of 39th in the ATP rankings himself, proved no match for the 22-time grand slam winner, who dismantled him inside an hour and 22 minutes.

Djokovic had looked poised for a near-flawless performance, with a late lost service game at 5-1 up in the second set the only major blemish on his display.

"It's been a great evening for me," Djokovic said in his post-match interview. 

"Yesterday [against Tomas Machac], I really had to work hard to get a win. Tonight, right from the blocks, I think I was sharp. I definitely played better than I did last night.

"Maybe the last three or four games weren't the best to close the match, but I managed to find a good serve in the end.

"I'm very pleased with the performance and with the way I felt on the court, and hopefully things can go in the right direction for tomorrow."

Djokovic, who remains undefeated in 2023, is bidding to win the Dubai title for a sixth time, in what represents his first tournament since he won the Australian Open in January. 

Elsewhere, second and third seeds Andrey Rublev and Daniil Medvedev joined Djokovic in easing their way into the last eight.

The former was made to work by Spain's Alejandro Davidovich Fokina however, recovering for a 1-6 7-6 (8-6) 7-6 (7-3) win, while the latter saw off Alexander Bublik 6-4 6-2.

Fourth seed Felix Auger-Aliassime crashed out with a surprise 7-6 (7-4) 6-4 loss to Italy's Lorenzo Sonego, who is rewarded with a last-eight clash against seventh seed Alexander Zverev.

Novak Djokovic was made to work hard for his 18th consecutive victory, eventually putting away Tomas Machac in the first round of the Dubai Tennis Championships.

Djokovic, who is celebrating a record 378th week as world number one, had to rely on a third-set tie-break to finally get over the line, defeating his Czech opponent 6-3 3-6 7-6 (7-1) on Tuesday.

Machac is ranked 130th in the world, but caused Djokovic plenty of problems, earning 10 break points across the match, though he was only able to convert three.

Djokovic had a 4-1 lead in the deciding set before Machac fought back to force a tie-break, but the Australian Open champion ultimately had few problems at 6-6 as he won seven of the eight points played to clinch the win.

"Tomas certainly didn't play like the No. 130 in the world today," Djokovic said of his opponent. "He was giving me all kinds of trouble. But I guess when it mattered, I found another gear."

Djokovic, who is still undefeated in 2023, will face Tallon Griekspoor in the second round.

Elsewhere, fresh off two titles in as many weeks, third seed Daniil Medvedev eased past Matteo Arnaldi 6-4 6-2 to tee up a tie with Alexander Bublik next after his opponent Alexandar Lazarov retired hurt with Bublik leading 6-1 1-0.

Felix Auger-Aliassime defeated Maxime Cressy 7-6 (7-4) 3-6 6-3, but sixth seed Karen Khachanov is out after he was beaten 7-5 6-2 by Botic van de Zandschulp.

The Dutchman will take on Mikael Ymer in the second round after his 6-2 6-3 win against Francesco Passaro, while eighth seed Borna Coric and Dan Evans played just four games before the latter retired hurt.

Christopher O'Connell set up a match against Alexander Zverev in the next round after he overcame Emil Ruusuvuori 7-5 6-4.

Novak Djokovic remains set on more success after surpassing Steffi Graf's record for weeks spent at world number one.

On Monday, Djokovic celebrated a 378th week as the best player in men's tennis, which overtook the all-time record (for men or women) set by Graf.

Like Graf, Djokovic has won 22 grand slam titles, though the 35-year-old remains in the hunt for more glory.

After his Australian Open triumph earlier this season, Djokovic will be hoping a 94th ATP Tour-level title comes his way at this week's Dubai Tennis Championships.

"I still want more achievements," Djokovic said ahead of breaking Graf's record.

"I could not have imagined this, I was dreaming as a kid to be Wimbledon champion, to be number one in the world. I achieved those dreams in 2011.

"After that, I wanted more. Of course, I'm driven by the goals. I'm as dedicated to the sport really as anybody else.

"It's surreal in a way to be that many weeks at world number one, to match Steffi Graf, who is one of the all-time greats of our sport. Just being among these legendary names is flattering. I'm very proud."

Djokovic's campaign in Dubai starts against Tomas Machac on Tuesday.

Tommy Haas says Carlos Alcaraz is already primed to succeed Novak Djokovic and Rafael Nadal at the very top of tennis.

Alcaraz became the youngest men's world number one when he won his maiden grand slam title at the US Open last year.

The Spaniard missed this year's Australian Open due to an injury, allowing Djokovic to reclaim his place at the summit of the rankings with his 10th triumph in Melbourne.

Djokovic celebrated a record-breaking 378th week at number one on Monday, the day after Alcaraz had fallen short against Cameron Norrie in the Rio Open final.

Alcaraz, who has already won seven singles titles, battled through pain in Brazil but ultimately slipped to a 5-7 6-4 7-5 defeat against the opponent he beat in the Argentina Open final a week earlier.

With the 19-year-old having already reached 10 tour-level finals, though, former world number two Haas has no doubt Alcaraz is in line to enjoy success close to that of Djokovic and Nadal.

"Yes, you have to say that he already is [ready]," Haas told Stats Perform.

"He had an unbelievable year last year, right. I think he won a title down there in Rio, on clay then he came to Indian Wells playing extremely good tennis, losing a tough battle match against Rafa in the quarters.

"They played some incredible tennis and you could just tell the way he moves on the court, his mental toughness and the shot selection that he has, the repertoire there is, there's nothing really missing.

"Being that young sometimes can be like the only hindrance in my mind because maybe you want it too much, or you overthink things. Or maybe in this case, you clearly don't overthink things, and you just go out and play your best and fight and give it everything you have.

"A lot of respect obviously goes to his team, his family, his coach. He just kind of went on that run, winning [in] Madrid, in his home country. And then winning his first slam, the US Open and being the youngest world number one, so what a quick rise. Just unreal, I can't even imagine how his life has been turned upside down in many ways."

The only concern, as far as Haas sees it, is Alcaraz's injury worries.

"He's a guy that wants to stick around, and remain up there at the top for a very, very long time," Haas added.

"With his game, and his potential, if he stays healthy... that's the thing, he's been already a little bit injured at a young age. So, that's a little bit of a warning sign.

"If he can remain healthy, I think that's where the team is obviously very smart. I think they're trying to build up his body still, to sustain the crazy amount of travel and the stress on the body that tennis creates on you to make sure that he has a long career, because that's what everybody hopes and dreams for."

Novak Djokovic has brought up his 378th week as world number one.

That sees the 35-year-old, 22-time grand slam champion overtake Steffi Graff as the outright record holder for the amount of weeks spent at the top of the world.

Djokovic won his first major in 2008, and has not looked back.

To mark his achievement, Stats Perform has used Opta data to run through the key numbers from Djokovic's stellar career.

ATP Tour titan

7 - Djokovic has been year-end number one on seven occasions, one more than Pete Sampras and two more than Roger Federer, Rafael Nadal and Jimmy Connors.

93 - Djokovic has won 93 ATP Tour titles. Only three players have won more in the Open Era.

1,249 - The Serbian has played 1,249 matches on the ATP Tour. Just Nadal (1,288), Ivan Lendl (1,310), Federer (1,526) and Jimmy Connors (1,558) have played more.

350 - Djokovic has featured against top-10 opponents 350 times, more than any other player in history. He has won 243 of these matches. 

A master at work

22 - Only Serena Williams (23) has more major titles in the Open Era than Djokovic, who is tied with Nadal for the most grand slam triumphs when it comes to men.

33 - Djokovic has played in 33 grand slam finals, the most by any male player in the Open Era. Only Chris Evert (34) has more when it comes to female players.

37 - He has won 37 per cent of the grand slam titles on offer since (and including) his maiden major success in Melbourne in 2008. Nadal has won 32 per cent (19/60) and Feder 13 per cent (8/60).

28 - No player has won more consecutive matches at the Australian Open than Djokovic (28), while he has won 28 straight at the Wimbledon, too.

10 - Djokovic is the first player to play a minimum of 10 semi-finals at each of the grand slams.

2 - After his 10th triumph at the Australian Open, Djokovic became the second male player in the Open Era to secure 10+ titles in a single grand slam, after Nadal (14 French Open titles).

38 - No player has won more ATP 1000 titles than Djokovic (38), Eleven of those titles were won without losing a set.

6 - Djokovic has won the most ATP 1000 titles won in a single season (six).

Nemesis Nadal

59 - Nadal is the player Djokovic has faced the most times in his career (59). The Spaniard has lost 30 of those matches, marking Djokovic's best win tally against a single opponent.

179 - Djokovic has faced players from Spain 179 times, winning 131 matches and losing 48.

29 - He has won 130 matches against left-handed players, losing 40. Of those 40 defeats, 29 were inflicted by Nadal.

100 - Djokovic has a 100 per cent record against four players: Gael Monfils (18-0), Jeremy Chardy (14-0), Milos Raonic (12-0) and Andreas Seppi (12-0).

Novak Djokovic is amassing such a dossier of evidence that no sober judge would dispute his claims, but debate still rages as to who is the greatest men's tennis player of all time.

The 35-year-old has now racked up 378 weeks at number one on the singles rankings, not only improving his record among the men but also this week going past Steffi Graf, the leader on the women's tour.

Djokovic has won 10 of the last 16 grand slams he has contested, all since turning 30, and has moved level with Rafael Nadal on 22 singles majors, the most ever captured by a man.

His stockpiling of Masters 1000 titles is bordering on being greedy, with a record 38 tucked away, and although he turns 36 in May there is no sign of Djokovic slowing down.

Tommy Haas snatched three wins from nine encounters with Djokovic, while the Serbian was going up through the gears early in his career.

Haas told Stats Perform he sees Djokovic as a player who wants to "end that debate" over who is the greatest, but there are good grounds to reason the man from Belgrade has already done enough.

Djokovic's compelling case

With plenty of miles left in his legs, Djokovic has already reached 33 grand slam finals (W22 L11), the most by any man. It puts him level with Serena Williams (W23 L10) and one behind Chris Evert (W18 L16), who is perhaps a surprising leader in this field.

Given his form in the past 12 months, it would be astonishing if Djokovic does not reach more slam finals this year.

He has also won 38 Masters titles – the next rung down from the grand slams – and is not just the only singles player to have won every one of these nine tournaments, he has won each one at least twice.

Djokovic's six end-of-season ATP Finals titles puts him level with Federer.

Adding together grand slams, ATP Finals crowns and Masters 1000 wins, Djokovic has 66 of these so-called 'Big Titles', seven more than Nadal, who sits second on the list. It bears pointing out the Masters events only began in 1990, so this puts players of the modern era at an advantage, but the domination of these events by the likes of Djokovic, Nadal and Federer mirrors their unprecedented grand slam supremacy.

Djokovic has an 83.5 per cent career win-loss record (W 1,043, L 206), the best of all players with at least 200 matches on tour during the Open Era (since 1968).

In the slams, his win-loss record of 341-47 gives Djokovic an 87.9 per cent winning record, just a shade behind Nadal's 88 per cent, and ahead of Federer (86 per cent).

Djokovic is rapidly closing in on overtaking Nadal's win percentage, having powered through his last 14 matches at the majors, triumphing at Wimbledon and the Australian Open.

These winning percentages at the slams by the Big Three are not the absolute highest of all time, but considering Djokovic, Nadal and Federer have regularly had to play one another over the past two decades, that is easily explained.

Only Bjorn Borg (71.1 per cent) has a higher win percentage against top-10 players than Djokovic's 69.4 per cent, but Borg's career was relatively brief, stepping off the tour in his mid-20s, with Djokovic a model of sustained excellence.

Djokovic is playing in Dubai this week, seeking more trophy success.

The expert's view

"He's the ultimate competitive warrior out there," says Tommy Haas. "He doesn't leave a stone unturned, does everything that he possibly can to be the best that he can be."

Haas is now tournament director at the Indian Wells Masters – aka the BNP Paribas Open – and he had better results than most against Djokovic, scoring wins on grass in Halle and Wimbledon in 2009 before repeating the trick on hard court in Miami four years later.

Djokovic, it can be argued, is a better player at 35 than he was at 25, and he is certainly more dominant. The man who feeds off his inner "wolf energy" has lost none of his bite.

"He's spoken about it himself many times, the sort of upbringing that he had, the experiences that he had to go through just to put so much grit in him, so much fire and fighting power. And you see it. The guy is an absolute beast out there," Haas said.

"There's no doubt in my mind that in his mind he wants to become the greatest of all time and win the most slams and end that debate and I think that's that's what he's looking to do.

"We're getting a little bit ahead of ourselves now but let's just say he does have the most slams. He's won every Masters series there is, maybe the most of all of them as well. Longest number one, most slams and then I think there is no room to argue."

Is winning enough to define greatness?

Yes. It has to be. In hand-to-hand combat, whether in war or something as relatively frivolous at tennis, it's all about getting the better of the enemy. Then it's about continuing to do so, and if it's easy on the eye, all well and good.

Roger Federer played the most sumptuous tennis that made him a bigger draw than anyone, and the Swiss great was also a sensational winner to boot, and a charmer, but Djokovic is picking off his records one by one.

Does this make Djokovic the most popular tennis player of all time? No, he rarely exhibits the warmth of personality that Federer brought, the crowd-pleasing flourishes are in shorter supply, and he brings some of the bad press and occasional crowd antipathy on himself.

But winning is the priority for Djokovic, and nobody does it better.

Haas says: "Really, can you say does he have the prettiest game or the best shot selection or this and that? Without Roger and without Rafa he would have been pushed to become that good of a player? Maybe not. And you have to always look at every generation pushing each other and all that stuff.

"And the debates can go on and on. Bjorn Borg retired when he was 26 years old, he won 11 slams. What if he would have played 10 more years? Yeah, he probably could have had 20."

But Djokovic has 22 and is hurtling towards Margaret Court's 24 slams, the most by a woman. There is no doubt he believes he can go beyond that, and keep going.

Shingo Kunieda won 28 wheelchair singles majors, and Djokovic might even get up towards that number.

For now, the number that matters is number one. Whether you like him or not, the man they call Nole is hurtling into history as the champion supreme.

Novak Djokovic says his participation at the Indian Wells Open and Miami Open is "out of his control".

Djokovic, who last month won the Australian Open to move level with Rafael Nadal on 22 grand slam titles, has not played since claiming the title in Melbourne.

The world number one was nursing a hamstring issue throughout the season's first major, but he confirmed at a press conference in Belgrade on Wednesday that he will return to action at the Dubai Tennis Championships next week.

Djokovic could not compete in the United States last season due to his COVID-19 vaccination status, though his brother Djordje has claimed the 35-year-old has applied for a "special permit" to enter the country.

He has received clearance from the tournament organisers to play at the two Masters 1000 events at Indian Wells and in Miami but now faces a wait to find out if the U.S. government will grant him entry.

"The process for that has started. It is out of my control now," Djokovic said.

"I'd love to play and I'm glad I received the approval of directors in Miami and Indian Wells. I hope the decision makers will give the approval."

On his progress on the injury front, Djokovic explained: "As for the injury I sustained at the Australian Open, it's healed, but I'm not 100 per cent yet.

"Things are looking very good. As a team, we made the decision to go to Dubai."

Djokovic has won the Dubai Tennis Championships five times, though the last of those titles came in 2020.

He was knocked out by Jiri Vesely in the quarter-finals last year.

Djokovic this week tied Steffi Graf on 377 weeks spent as world number one.

The outright record is set to become his next week, with Carlos Alcaraz unable to surpass him even if the young Spaniard wins the Rio Open.
