Novak Djokovic has no doubt in his own mind he is the best tennis player in the world, regardless of what the rankings say.

After clinching a record-equalling sixth ATP Finals title by downing Casper Ruud in Turin, Djokovic reflected on a turbulent 2022 season in which he was unable to play in two of the four grand slam events.

His refusal to accept a COVID-19 vaccination meant Djokovic was denied permission to compete at the Australian Open and US Open, while the various tennis authorities' reaction to the Ukraine crisis meant no ranking points were on offer at Wimbledon.

Indeed, Djokovic successfully defended his title at the All England Club, but in doing so he lost all of his 2,000 points for being the 2021 champion.

As such, he entered the ATP Finals as the world number eight, with his unbeaten run at the tournament seeing him collect 1,500 points and jump up to fifth on the ATP ranking list.

Carlos Alcaraz is the number one for now, after a stellar season for the 19-year-old Spaniard in which the highlight was his US Open victory, but Djokovic will be the favourite with many for the Australian Open, with authorities expected to allow him to play next year.

Asked if he was the world's best player, Djokovic said: "I'm not. I'm fifth."

That came with a smile from the Serbian, who added: "This week I probably am [the best]. Overall the rankings are showing who had the best year, and Alcaraz is the number one in the world. Not much to say about that.

"But in my mind I always see myself as the best player in the world, of course. I have that kind of mentality and that kind of approach. Regardless of who is across the net, regardless of what the surface is, regardless of what season it is, what number of the professional season in my career we're facing, I mean, it's always the same. The ambitions are as high as possible.

"That kind of approach, I feel it brought me to where I am sitting here today as a 35-year-old, holding one of the biggest trophies in the sport."

The 21-time grand slam winner, one behind Rafael Nadal on the men's all-time singles list, said the prospects for future success come down to his "love and passion" for tennis.

"As long as that's there I'll do anything in my power to challenge the young guys for the biggest trophies," Djokovic said.

"I don't know what the future holds, but I know that what I hold in my mind is a huge hunger still to win trophies, make history of this sport, compete on the highest level all around the world, bring good emotions to sports fans, tennis fans."

Djokovic was greeted after the final by Milan striker Zlatan Ibrahimovic, another sporting evergreen at the age of 41, albeit very much in his career twilight.

The same cannot be said yet for Djokovic, who may have several seasons left at this high level.

His coach, former Wimbledon champion Goran Ivanisevic, watched on admiringly as Djokovic won 7-5 6-3 in Turin against Ruud on Sunday.

According to Croatian Ivanisevic, the key to Djokovic's success in his mid-thirties is his relentless work rate.

"He's practising even harder than when he was 22," said Ivanisevic. "That's why he's still so good and that's why he's still going to be even better.

"The will to practise, the will to improve, the will to be better is amazing. He's taking care of his body. In my time we stopped tennis at 30, 31. You were already an old guy ready to leave.

"They all talk about, yes, young players are coming. It's great for tennis. You have the youngest number one in the world who made unbelievable things this year, Carlos. But look at Novak. He's still hungry, he's still winning the tournament, playing unbelievable tennis. He's still already thinking now about preparation for next season.

"Till he's like that, in his mind he's going to be always competitive, favourite to win majors and the big tournaments."

Novak Djokovic ended his "roller coaster year" on a roaring high with victory at the ATP Finals, matching Roger Federer's record of six titles by sinking the hopes of Casper Ruud.

The Serbian said he had spent the season "on the needles", his colourful way of describing the nervousness and discomfort he had experienced during a campaign which saw him prevented from playing in Australia and North America.

Djokovic, who has refused to take a COVID-19 vaccination, has seen his career suffer because of that firm stance. He was thrown out of Australia in January, a humiliating way to begin the year.

Yet there is little doubting the 35-year-old remains the pre-eminent player on tour heading towards the 2023 season, even with the rise of Carlos Alcaraz, who ends the year as world number one.

A first ATP Finals triumph for Djokovic came in 2008, and he then won four in a row from 2012 to 2015, and now he has carried off the trophy once more, plus a cheque worth $4.74million, the biggest prize ever paid out in tennis.

"Seven years, it's been a long time. At the same time, the fact I've waited seven years makes this victory even sweeter and even bigger," Djokovic said.

Speaking on Amazon Prime, Djokovic said the win after all he has gone through felt "huge".

"I probably talked about this season and how unusual it is 1,000 times prior to this interview, so I'm not going to repeat what most people who follow tennis know," he said.

"[It's] just a big relief and satisfaction, and also I look forward to having a couple of weeks off, because I've been on the needles the entire year, whether for tournaments or waiting for permissions to go somewhere, so I'm really glad I managed to end it in a positive way."

He is the oldest champion in the tournament's 53-year history, breaking a record held by Federer, who was 30 when he won in 2011.

Djokovic said it was "really, really impressive" for Ruud to have reached grand slam finals in Paris and New York, and the ATP Finals title match, in a stellar year for the 23-year-old Norwegian.

But Djokovic was ruthless in Sunday's final, emerging a 7-5 6-3 winner thanks to a break of serve in each set, earning a fifth title of his disrupted year following wins at Wimbledon, Rome, Astana and Tel Aviv.

Thanking his team and supporters during the trophy presentation for "going through some tough times" with him, Djokovic said there were moments where he had needed "a shoulder to lean on, a shoulder to cry on".

The 21-time grand slam winner added: "It's been a roller coaster year really, something I've never experienced ever before in my life, and only we know what we've been through."

Novak Djokovic ended his tumultuous year on a breathtaking high by dismantling Casper Ruud to win the title match at the ATP Finals, pocketing almost $5million in the process.

The man who was deported from Australia after a vaccination and visa dispute in January, then refused entry to the United States later in the campaign, scorched to a 7-5 6-3 victory against rising star Ruud.

This was a sixth triumph for Djokovic at the ATP Finals, matching Roger Federer's record, and at the age of 35 he is also the oldest champion at the event. Federer was previously the oldest, being 30 when he captured the 2011 title in London.

The tournament has since moved to Turin, and Djokovic reels in $4.74million for a victory that shows he remains the player to beat, wherever and whenever he gets the chance to play.

Serbian superstar Djokovic had two chances to break in the second game but Ruud resisted, and the younger man saved another break point in the eighth game too, but a further opportunity came at 6-5 after Ruud paddled a backhand into the net. The 23-year-old Norwegian sent the ball long in the next rally to slip behind.

It was becoming a masterclass from Djokovic and he was pummelling the ball from the back of the court, breaking Ruud's serve for a 3-1 lead in the second set. Djokovic later won a 36-shot rally to set up championship point, sealing victory with an ace down the centre.

Ruud, a runner-up this season at the French Open and US Open, had watched each of Djokovic's previous ATP Finals victories on television, and this time he had a prime spot to witness the 21-time grand slam winner at the top of his game.

Try as he might, Ruud could not find a way to fight back once the stranglehold was with Djokovic, who heads towards 2023 with his appetite for the biggest trophies in tennis far from sated.

Casper Ruud swept through to a showdown with Novak Djokovic at the ATP Finals, making light work of Andrey Rublev to reach the trophy match.

The 23-year-old Norwegian has enjoyed a stunning season, reaching two grand slam finals, and his 6-2 6-4 semi-final dismissal of Russian Rublev was impressively authoritative.

After Ruud coasted through the opening set, the occasion fell wholly flat when Ruud broke serve in the first game of the second, and did so again in the third game.

Rublev sat shaking his head at his chair in the break between games, also shrugging his shoulders towards his support team and looking lost for ideas.

He only began to make an impact after slipping 4-0 behind, and at 5-2 he broke Ruud's serve to narrow the gap and give the Turin crowd hope the contest could take off.

At 5-4, it was briefly tense, but Ruud served for the match for a second time and this time made it count, sealing victory with a brilliant backhand winner to become the first Scandinavian finalist at the ATP Finals since Stefan Edberg in 1990.

Ruud will overtake Rafael Nadal and end the year at number two in the ATP rankings should he carry off the title on Sunday; however, he has a 0-3 career record against Djokovic. Djokovic earlier battled past Taylor Fritz by winning a pair of tight tie-breaks to earn a straight-sets victory in the first of Saturday's semi-finals.

Novak Djokovic sealed his place in the final of the ATP Finals after edging past Taylor Fritz 7-6 (7-5) 7-6 (8-6) in Turin on Saturday.

The Serbian, who is bidding to equal Roger Federer's record of six ATP Finals titles, overcame Daniil Medvedev in a bruising three-hour contest on Friday, and he was again made to work hard for victory against spirited American Fritz.

Djokovic struck first in the opening set with a break to love in the fifth game, yet Fritz responded immediately to level at 3-3.

A tie-break was needed to separate them after that, with Djokovic's superb forehand winner sealing the first set in style.

Fritz broke Djokovic in the opening game of the second set, but a simple missed backhand from the American helped his opponent break back to make it 5-5.

That set the stage for a high-quality tie-break, which Djokovic ultimately won to claim victory in one hour and 54 minutes.

"I had to fight to survive," Djokovic said on court afterwards. "I didn't feel very reactive today or very comfortable.

"I knew coming into today's match from yesterday's gruelling battle against Medvedev it would take me some time to adjust and find the dynamic movement I need against Fritz, who is one of the best servers on the tour.

"I am very pleased to have overcome this one as I don't think it was one of my best days with my tennis, but I managed to hang in there."

Should Djokovic beat Casper Ruud or Andrey Rublev in Sunday's final, he will claim the largest payday in tennis history, with $4,740,300 up for grabs for sealing the trophy undefeated.

Novak Djokovic finished with a perfect group-stage record at the ATP Finals after beating Daniil Medvedev 6-3 6-7 (5-7) 7-6 (7-2) in a lengthy three-hour contest on Friday.

Djokovic – who is bidding to equal Roger Federer's record of six ATP Finals titles – sealed his spot in the last four by beating Andrey Rublev on Wednesday, but he was in no mood to do the already-eliminated Medvedev any favours in Turin.

The 21-time grand slam winner dominated the opening set, winning 89 per cent of points behind his first serve and hitting several outstanding cross-court forehand winners.

Djokovic began the second set in similar fashion, but saw his standards dip when he returned to the court following a long stoppage at 5-5.

The rejuvenated Medvedev forced a tie-break with a delightful drop shot before taking advantage of a rare double fault from Djokovic to level the match. 

With the exhausted Djokovic visibly shaking ahead of the decider and his semi-final against Taylor Fritz looming, the Serbian's commitment to Friday's dead rubber could have been called into question, but he found a second wind to take the match away from Medvedev.

Djokovic was on the ropes when he saw his serve broken for the first time in the tournament nine games into the third set, but he hit back immediately and then forced another tie-break. 

The Serbian was back to his exquisite best from there on as he sealed the win by hitting a huge forehand winner down the line, though the drawn-out nature of his victory could yet play into Fritz's hands.

Having qualified for his first ATP Finals, Taylor Fritz is now through to the last-four as he prevailed 7-6 (7-4) 6-7 (5-7) 6-2 against Felix Auger-Aliassime in a match where the winner would advance from the Green Group.

There were no break point opportunities in the first set on the back of elite serving from both players, with Fritz converting 90 per cent (19/21) of his accurate first serves into points. However, after giving up a mini-break to begin the tiebreaker, Fritz steadied and snatched three mini-breaks of his own to take the opener.

It was more of the same in the second set, with Auger-Aliassime taking his turn to dominate with his serve. In a near carbon-copy, the Canadian won exactly 90 per cent (19/21) of the first serves he landed fair, and Fritz had to save the only three breaks points of the frame to force another tiebreaker.

When Auger-Aliassime's serve slipped in the third set, so did any chance of taking the match. He won only 52 per cent of his service points (14/27) in the frame, while Fritz maintained a stellar level at 89 per cent (16/18), securing a double-break and the victory.

Having finished second in his group, Fritz will next take on the winner of the Red Group, which will likely be Novak Djokovic as he is the only undefeated player through two games.

Rafael Nadal has welcomed the news that Novak Djokovic will be free to compete at the Australian Open.

Djokovic was at the centre of controversy in January following his attempts to play in this year's tournament in Melbourne despite being unvaccinated against COVID-19, and the 21-time grand slam winner was eventually deported after having his visa cancelled on public health grounds.

However, Djokovic recently confirmed he will be free to play in the 2023 Australian Open after his three-year ban from entering the country was overturned.

Nadal and Djokovic have dominated tennis along with the now-retired Roger Federer for much of the last two decades, and the Spaniard was pleased to hear of his rival's availability to compete.

"I always said the same; tennis is better when the best players are on the court," he said. "At the end we don't have to create many stories. Even if it was a big mess what happened last year in Australia, it was not good for our sport.

"That was the past. Roger is not playing any more. I missed a lot of grand slams [with] injuries. Last year, Novak was not able to play there.

"That's the past. What's next is Novak will be able to play again. That's the best news possible, especially knowing that now the virus is more under control it seems around the world. So why not? Happy for him. Happy for the tournament. Happy for the fans. That's it."

Nadal beat Casper Ruud in his final game at the ATP Finals on Thursday.

Novak Djokovic boosted his hopes of claiming a record-equalling sixth ATP Finals title by clinching a semi-final spot with a 6-4 6-1 win over Andrey Rublev in Turin.

Having overcome Stefanos Tsitsipas in his opening red group match, Djokovic endured spells of pressure from the sixth seed throughout Wednesday's opening set before clinching the all-important break in the 10th game.

The 21-time grand slam winner found the going far easier in the second set, breaking Rublev's serve at the first opportunity before repeating the trick in the sixth game.

Djokovic's backhand was particularly impressive as he dominated proceedings from the baseline, while the Serbian won 94 per cent of points behind his first serve and did not give up a single break point during the match.

The 35-year-old only committed six unforced errors en route to his 68-minute victory, as he joined Casper Ruud in sealing a place in the final four in Turin. 

Djokovic has now won his opening two group matches in four of his last five campaigns at the ATP Finals, and he appears the strong favourite to equal Roger Federer's record of six titles at the competition.

Novak Djokovic has confirmed he will be free to play in the 2023 Australian Open after his three-year ban from entering the country was overturned.

Djokovic was at the centre of huge controversy in January following his attempts to play in Melbourne despite being unvaccinated against COVID-19.

The 21-time grand slam winner was eventually deported after having his visa cancelled on public health grounds. 

He was initially allowed to enter the country in spite of his vaccine status, amid widespread furore over his apparent flaunting of strict regulations.

His deportation resulted in an automatic three-year ban. However, with the vaccine mandate that was in place earlier this year no longer a barrier for Djokovic, the decision has been made by immigration minister Andrew Giles to hand him a visa.

Speaking at the ATP Finals in Turin on Wednesday, Djokovic confirmed the decision, saying: "Well, of course, I was very happy to receive the news yesterday.

"It was a relief, obviously, knowing what I and people closest to me in my life have been through this year with what happened in Australia and post-Australia. I could not receive better news for sure – during this tournament as well."

Djokovic has won the Australian Open singles title nine times in his career, last doing so in 2021 when he beat Daniil Medvedev in the final.

Novak Djokovic begun his ATP Finals campaign with a straight set victory over Stefanos Tsitsipas in Turin, ending the Greek's hopes of finishing the year ranked number one.

The five-time champion emerged as a 6-4 7-6 (7-4) victor to go top of the Red Group above Andrey Rublev, the Russian having defeated compatriot Daniil Medvedev earlier on Monday.

Tsitsipas needed to win the title in Turin without losing in order to dethrone the injured Carlos Alcaraz at the top of the rankings, but now cannot catch the Spaniard.

Djokovic did not face a break point as he served superbly in the opening set, not allowing the second seed a look-in after breaking in the first game of the match.

Tsitsipas responded well in the second set, firing down seven aces and winning 88 per cent of points behind his first serve, but seventh seed Djokovic stood firm to take the set to a tie-break.

A battling Tsitsipas fought back from 5-1 down to 5-4 in the breaker, but Djokovic did not falter, coming up with a powerful serve that his opponent was unable to return to make a winning start in his quest for a record-equalling sixth ATP Finals title.

Rafael Nadal does not need extra motivation to win the ATP Finals for the first time in his legendary career, while Novak Djokovic is looking for a "perfect ending" to 2022 in Turin.

Spanish great Nadal has won 22 singles grand slam titles, a record in the men's game, but has surprisingly never been crowned champion at the season-ending event.

Nadal made a personal-best start to 2022, winning 20 straight matches and lifting the Australian Open title.

However, he has only played once since the US Open due to becoming a father for the first time and recuperating from injuries.

Still, at the age of 36, Nadal is grateful to still be getting a crack at finally ticking off the ATP Finals on his impressive list of accomplishments.

"I try my best in every single event. That's true. Doesn't matter if I won it [in the past] or not," Nadal, a two-time runner-up, said at an ATP media day prior to the tournament in Turin.

"When I enter a tennis tournament, I want to win and I'm going to try my best to achieve that goal. Here I was not able to make it, I was not good enough to make it in the past.

"So I just accept that and I'm happy to give myself another chance at the age of 36 — something, for me, that was difficult to imagine years ago.

"Of course it's going to be a challenge, but I hope I will be ready to give myself a chance. That's what I am looking for, just practising as good as possible with the right attitude and just trying to be ready for the action that's going to start on Sunday."

Djokovic's season has been a complicated one. Absent from the Australian and US Opens due to not being vaccinated against COVID-19, the Serbian great did triumph at Wimbledon, but there were no ranking points on offer at SW19.

He has slipped to eighth in the rankings as a result but does have four titles to his name in 2022 and Djokovic is eyeing a record-equalling sixth ATP Finals title and first since 2015.

"It would be a perfect ending," Djokovic said." The cherry on the cake, for sure, but it's a long way. It's a long week.

"You've got to play the best players in the world. You have to play more or less everyone in this tournament at least once, so I look forward to it.

"I've had experience in this tournament, in this format, many times and hopefully that can serve me in a good way."

In recent years, the notable absentee at the ATP Finals has been Roger Federer, with his last appearance in the tournament coming in 2019.

The lack of Federer at the showpiece event will be felt even more apparent this year after the Swiss maestro retired from tennis in September, though it is the absence of a player at the other end of his career that is more relevant in Turin.

World number one Carlos Alcaraz had to withdraw from the tournament after suffering an abdominal tear, which means his status at the top of the men's game is in jeopardy.

Rafael Nadal has spoken well of his 19-year-old compatriot in the past, but is not ready to pass the torch just yet, and could even topple Alcaraz from his number one spot.

The 22-time grand slam champion has finished as year-end number one five times previously, most recently in 2019. Should he accomplish the feat again this year it would put him in joint-second for most year-end finishes at the top of the ATP Rankings (since 1973) along with Pete Sampras (six).

In order to do so, Nadal will need to win the tournament, something he has never done before.

However, he comes into his 11th appearance in good form, and has won 32 per cent of his return games in 2022, the highest percentage by any player this year, and has converted 43.8 per cent of his break points in 2022, the third best amongst all players.

Stefanos Tsitsipas, meanwhile, is the other competitor who can knock Alcaraz off top spot, though his task to do so is a little more complicated as he needs to win every match on the way to the title in Turin. 

No player has played more matches in 2022 than Tsitsipas (80), 21 on clay, 11 on grass and 48 on hard courts; he has won 59 of them and lost 21.

Should neither man win at the Pala Alpitour, Alcaraz will breathe a sigh of relief and earn his first year-end number one finish, having taken his place after winning the US Open in September.

Nadal has been drawn into the Green Group with Casper Ruud, Felix Auger-Aliassime and Taylor Fritz, while Tsitsipas will be in the Red Group alongside Daniil Medvedev, Andrey Rublev and Novak Djokovic.

Djokovic can equal Federer record

One man surprisingly unable to end the year as number one is Djokovic, despite having done so on more occasions than anyone else in history (seven).

However, the 21-time grand slam champion can still make his mark in Italy.

Djokovic has had an up-and-down year, only playing in two of the four grand slams due to his vaccination status, though he was able to win Wimbledon for the seventh time, beating Nick Kyrgios in the final.

Should the Serbian go all the way and lift what would be his sixth ATP Finals title, he will go level with Federer for most victories since the tournament began in 1970.

Among the eight participating players in this year's tournament, Djokovic has won 87 per cent of his service games in 2022, the best percentage among these players and the sixth overall.

It would be quite the ending to the year for Djokovic, who finds himself in the unusual position of sitting eighth in the world rankings, and at the age of 35, who knows how many more appearances he will make at the event?

Strong field promises fireworks

As is the intent of the format, the ATP Finals should be a tightly-contested few days as the best men's players in the world come together.

Ruud will be looking to add to an already impressive season, having reached two grand slam finals and winning three tour-level titles, while Fritz is aiming to carry on the fine lineage of American players to have won the tournament.

Players from the United States have won the ATP finals 16 times, with Sampras and Ivan Lendl winning five of them each. It is the most by any country and 10 more than next best Switzerland (six, all Federer) and Germany (also six, three wins for Boris Becker, one for Michael Stich and two for last year's champion, Alexander Zverev).

Auger-Aliassime has had a strong end to the year, beating Djokovic at the Laver Cup before winning three titles in as many weeks in Florence, Antwerp and Basel.

Only John Isner (895) has recorded more aces in 2022 than Auger-Aliassime, who has registered 852 in total, averaging 10.9 per match.

"All the players who participate [at the ATP Finals], I have already faced them, I have beaten them," the Canadian recently said. "So for me, there's no reason why I can't show up to this tournament with the aim of winning it."

Medvedev was world number one as recently as September but enters this tournament in fifth, though he did win the Vienna ATP 500 event last month, while his first opponent in Turin, Rublev, enters with a 2022 record of 49-18, looking for his second straight 50-win season.

Whoever comes out on top at this year's ATP Finals, the race for supremacy in 2023 promises to be as delightfully chaotic.

Rafael Nadal and Nick Kyrgios could face off in the inaugural United Cup, while WTA world number one Iga Swiatek will represent Poland.

The United Cup is the new warm-up tournament for the ATP and WTA Tour seasons, and will take place in Australia in December and January.

While ATP world number one Carlos Alcaraz will not feature, compatriot Nadal will be competing for Spain, and they have been drawn alongside Australia and Great Britain in Group D.

Those matches will be played in Perth, with a clash between Nadal and Kyrgios, who have enjoyed an entertaining rivalry down the years, in the offing.

They were set to meet in the semi-finals at Wimbledon this year, but Nadal withdrew due to injury, handing Kyrgios a walkover into his first grand slam final, which he lost to Novak Djokovic, who will not be playing in Australia.

Serbia are not among the batch of teams taking part, but even so, there remains doubt whether Djokovic would be able to enter Australia given his stance against the COVID-19 vaccine, which eventually saw him deported from the country after a drawn-out legal battle ahead of this year's Australian Open.

Emma Raducanu has decided against playing for the British team, which also does not feature Andy Murray.

Casper Ruud, the beaten US Open finalist, will play for Norway in Group E, in Brisbane, while Alexander Zverev will be in action for Germany.

Swiatek is the biggest name from the WTA Tour to enter, with the brilliant 21-year-old lining up alongside Hubert Hurkacz for Poland in Group B.

Maria Sakkari and Stefanos Tsitsipas, along with his brother Petros, will team up for Greece in Group A.

Two more countries will be admitted to the tournament later in November.

Holger Rune stunned Novak Djokovic to win the Paris Masters title as the teenager confirmed his ascendancy into the tennis elite.

The 19-year-old defeated Djokovic 3-6 6-3 7-5, fending off the six-time champion at the indoor event to earn a place in the top 10 for the first time, becoming the first Danish man to reach such heights.

Rune becomes the first player since the ATP rankings were launched in 1973 to have beaten five top-10 players in the same tournament, other than at the season-ending ATP Finals.

His scalps on the route to his maiden Masters 1000 final included Hubert Hurkacz, Andrey Rublev, Carlos Alcaraz – who retired when trailing in their quarter-final – and Felix Auger-Aliassime.

Now Rune can add last year's Paris champion Djokovic to that list, defeating the 21-time grand slam winner who had described his young opponent as the future of tennis on the eve of the final.

Rune becomes the youngest Paris Masters champion since an 18-year-old Boris Becker triumphed in 1986, and he did it the hard way too, coming from behind after Djokovic made the stronger start.

Djokovic broke Rune's serve in the fourth game to lead 3-1 and take an early grip, soon seeing out the opening set.

Yet Rune charged 3-0 ahead in the second and grew in confidence. There was even a Djokovic-like raised fist after getting the better of his illustrious rival in one thrilling rally

Djokovic roared ahead in the decider, but not intimidated by the occasion, Rune struck back to recover the early break. 

Rune then broke to lead 6-5, as his Serbian opponent became erratic.

Nobody beats Djokovic without a fight though, and the 21-time grand slam winner had six chances to break back in the next game.

Rune survived them all and clinched victory on his second match point when Djokovic, who had been chasing a record-extending 39th ATP 1000 title, netted on the half-volley.

Addressing Rune in an on-court interview, Djokovic said: "You absolutely deserve this victory. What an amazing week you had.

"I'm not happy that you beat me, but on the other hand I'm happy for you because I like your personality, I think you're a very dedicated guy that loves tennis and puts a lot of hours into hard work.

"It's paying off for you, and I'm sure the future is bright for you and your team, so congratulations."

Rune, who is working with Serena Williams' former coach Patrick Mouratoglou, said: "This must be my favourite tournament now, I really enjoyed my time here."
