World number one Novak Djokovic said he does not have "much respect" for outspoken Australian star Nick Kyrgios away from the tennis court.

Kyrgios has been critical of Djokovic in an ongoing feud with the 17-time grand slam champion, who was labelled a "tool" by the former following a list of requests made to Tennis Australia (TA) and the Victorian government for tennis players stuck in hotel quarantine amid the coronavirus pandemic.

Former world number 13 Kyrgios was also critical of Djokovic's decision to stage the Adria Tour in Europe last August – in the midst of the COVID-19 crisis – having previously dubbed the Serb star "cringeworthy".

Djokovic rekindled his rivalry with Kyrgios after being asked about the 25-year-old on the eve of the Australian Open.

"I've said this before," Djokovic told reporters on Sunday. "I think he's good for the sport. Obviously he's someone that is different. He goes about his tennis, he goes about his off court things in his own authentic way. 

"I have respect for him. I have respect for everyone else really because everyone has a right and freedom to choose how they want to express themselves, what they want to do. My respect goes to him for the tennis he's playing. I think he's very talented guy. He's got a big game. He has proven that he has a quality to beat any player really in the world in the past.

"Off the court, I don't have much respect for him, to be honest. That's where I'll close it. I really don't have any further comments for him, his own comments for me or anything else he's trying to do."

Djokovic has won the past two Australian Open finals as he eyes a record-extending ninth Melbourne Park crown.

The 33-year-old, who opens his title defence against Jeremy Chardy on Monday, has won the Australian Open every time he has reached the semi-finals.

Djokovic has reached at least the semi-finals in seven of his last nine grand slam tournaments, winning five of them.

No male has won more Australian Open men's singles titles than Djokovic, who said: "It's a love affair. Probably something similar maybe not like Rafa [Nadal] has with the French Open, but I've been feeling more comfortable on the court each year that I've been coming back. 

"The more you win, obviously the more confidence you have and the more pleasant you feel on the court. It just feels right. If you're in the right state of mind, regardless of the surface, you have a better chance to play at your best.

"When I stepped on the court this year for the first time in the practice session, I relived some of the memories from last year, also the other years that I won the tournament here.

"It just gives me great sensation, great feeling, confidence. It feels right. It feels like the place where I should be and where I have historically always been able to perform my best tennis. Hopefully can be another successful year."

Asked if he still feels nerves, Djokovic – who is looking to close the gap on Rafael Nadal and Roger Federer (both 20) for the most slam trophies – added: "Every match, every match. Every single match. I don't want to speak on behalf of the other athletes, but I just feel like it's almost impossible to eliminate that kind of pressure, anticipation, the nerves coming into any match really for an athlete. At least in my case.

"It's just that I managed over the years to train myself, I think with the experience and with also the dedication that I had off the court to the mental preparation, that helped me react better to those kind of emotions. Sometimes I don't manage to overcome the pressures and the stress and nerves. Sometimes I do. It really just depends. Even though I've been blessed to experience a lot of success, especially here in Australia, but also in my career. I still feel that those failures, if you want to call them that way, even though I don't believe in failures, I just believe in opportunities to improve, kind of the lessons to be learned, but in those matches you lose, big matches, that's where you learn the most.

"That's where you're facing the kind of wall mentally. You're upset. You have a lot of different things happening, and you feel like you let yourself down. That's where it's the biggest opportunity for you to really address that and become stronger, more capable. You can get to know yourself a little bit on deeper levels. It still happens to me.

"Every single tournament, regardless of my previous success, of course I do feel that I have more confidence, more experience, maybe more training in understanding how to deal with these specific situations when I'm coming on the big court, being expected to win 99 per cent of the matches that I play.

"But it's still there. It's still there. I don't think it's ever going to go away. Especially when the occasion is big, when you're playing for the biggest trophies."

World number one Ash Barty ended her Australian Open preparations with a title after defeating Garbine Muguruza in the Yarra Valley Classic final.

Barty – gearing up for the year's first grand slam which gets underway in Melbourne on Monday – defeated sixth seed and 2020 Australian Open runner-up Muguruza 7-6 (7-3) 6-4 on Sunday.

Looking to add to her 2019 French Open crown, Australian star Barty claimed her ninth WTA Tour trophy and second on home soil.

"It was some of the better tennis I played throughout the whole week," Barty, who had not played in a competitive tournament since last February, told reporters in her post-match news conference.

"Garbine forced me to play at that level. It was a great final."

Barty added: "Overall it was a pretty solid performance. I'm still my harshest critic at times. That's the challenge of sport every day, is trying to get better and better."

Elsewhere in Melbourne, Elise Mertens clinched the Gippsland Trophy with a 6-4 6-1 win over Estonian veteran Kaia Kanepi.

Mertens – the seventh-seeded Belgian – returned to the winner's circle following two runner-up finishes in 2020.

As for Anett Kontaveit and Ann Li, they shared the Grampians Trophy on Sunday.

The Grampians Trophy did not have a final, the WTA announced, due to time running out before the Australian Open begins. Thursday's play was cancelled as a precautionary measure after a case of coronavirus involving a worker from a hotel that had housed quarantining tennis stars.

Kontaveit outlasted fifth seed Maria Sakkari 2-6 6-3 11-9 in the first semi-final, while Li upset seventh seed Jennifer Brady 7-6 (7-5) 6-7 (5-7) 10-6.

Kevin Durant will miss the Brooklyn Nets' clash with Eastern Conference leaders the Philadelphia 76ers due to the NBA's health and safety protocols.

Durant was in doubt for Saturday's showdown in Philadelphia following an unusual series of events on Friday.

The Nets star was named in the starting line-up to face the Toronto Raptors before being removed because of the league's health and safety protocols.

Durant was allowed to enter the game in the opening quarter, only to then exit in the third period – again due to coronavirus protocols – as the Nets lost 123-117.

Former MVP Durant finished with eight points, six rebounds and five assists in 19 minutes against the Raptors.

Prior to Saturday's matchup against the 76ers (16-7), Nets head coach Steve Nash said Durant is eligible to re-join the team on Friday.

Durant has been averaging 29.5 points, 7.4 rebounds and 5.2 assists per game for the Nets (14-10) this season.

Has the time come for a former world number one to end her wait for a first grand slam title since becoming a mother?

It is a question that has been asked time and again since Serena Williams returned in 2018 following the birth of her daughter, Alexis Olympia.

The legendary American must have long since become tired of being asked whether she can match Margaret Court's record of 24 major singles triumphs, with her last success coming when she was pregnant at the 2017 Australian Open.

While the 39-year-old - beaten in four grand slam finals after coming back to the tour - will be expected to mount a challenge over the next fortnight, it could be another mother who is celebrating at Melbourne Park.

It is eight years since Victoria Azarenka claimed her second grand slam title at the Australian Open, but the 31-year-old has shown there could be more to come.

Azarenka beat Williams for the first time in a major to reach the final of the US Open last year, but she then endured the agony of losing to Naomi Osaka.

That was her first championship match at a grand slam in seven years, having given birth to her son, Leo, late in 2016 before a prolonged child custody dispute badly disrupted her career.

A resurgent Azarenka took her tally of WTA Tour singles titles to 21 by winning the Western and Southern Open last August and was named the Comeback Player of the Year for 2020, as she headed back towards the peak of her powers.

The world number 13 claimed both of her grand slam titles at the Australian Open and will face Jessie Pegula in the first round next week.

Azarenka said she is enjoying her tennis more than ever and Michael Joyce, her former coach, believes she has a great chance of making a dream start to the year.

Joyce, who also coached Pegula, told Stats Perform News: "Vika has got as good a chance as anyone in Australia. She's back at the top, where she belongs.

"She won the Western and Southern and came so close at the [US] Open. She's also had some very tough draws as she's worked her way back, so she's done incredibly well to get back where she is.

"Opponents won't want to play her. If Vika gets through a couple of rounds, she can be very dangerous. Once she gets momentum, she can be hard to stop."

The great Martina Navratilova declared after Azarenka's run to the final at Flushing Meadows that she had witnessed "a new Vika" with extra punch in her shots" and "stronger than ever before".

Azarenka's positive outlook has also been evident off the court, as she recently launched a 'Think About It' podcast series, in which she engaged in in-depth conversations with the likes of motivational guru Trevor Moawad and professional rock climber Sasha DiGiulian.

The aim of the series was for Azarenka and her audience to learn from 'power players' in a variety of industries and show the strength that can be forged from vulnerability.

Azarenka's rivals may be feeling vulnerable in Melbourne as they think about how to go about beating the Belarus-born star.

Gregor Townsend praised the "calmness" and "togetherness" that saw Scotland end 38-years of Twickenham hurt, as Eddie Jones took responsibility for England's Calcutta Cup defeat.

Defending Six Nations champions England were caught cold by a dominant Scotland showing at an empty Twickenham, a venue where the visitors had not beaten their rivals since 1983.

Stuart Hogg and Finn Russell were influential in a game marking the 150th anniversary of this fixture, while rookie Cameron Redpath impressed and Duhan van der Merwe scored the game's only try in an 11-6 win.

Reflecting on a famous victory with ITV Sport, Scotland coach Townsend said: "I think there was just a calmness about how we played, a togetherness and an effort level that was superb. 

"We had a really good feeling with the way we trained and bonded. But you never know, it's the first game of the championship, there were a few who had their first game for a while or debuts. It was above expectations but what a start to the championship.

"It's impressive, to win here is very tough. Our line-out was superb, we really respect England's set-piece, their line-out has been outstanding the last couple of years.

"We put pressure on lines-outs, the scrums were good – then we were accurate in attack. It's difficult in these conditions to go wide, which we did. The kicking was excellent and so was the players' leadership – you could hear them in this empty stadium."

Captain Hogg revelled in the win but insisted the focus quickly turns to next week's home clash against Wales.

"It's amazing for us, I think we can't control what happened in the past that's gone, we can control what happens in the future," Hogg said, 

"We were a credit to a man, credit to England they provided a tough challenge. We stood up to it.

"We got excited during the week, we knew we could come down here and put in a performance. We looked after the ball in attack, went for multi-phase and caused England problems. We'll enjoy this one then it's onto Wales."

England also lost their 2020 Six Nations opener to France but rebounded to win a championship delayed by the coronavirus pandemic.

The hosts were left lacking in both the possession stats and penalty counts, and head coach Jones said the buck lies with him.

"Firstly congratulations to Scotland, they played very well, played with a lot intent and a lot of spirt, we just had one of those days, maybe I didn't prepare the team right, we were a long way from our best," Jones said.

"You just have days like that. It's my responsibility, every time a team goes on the pitch it's a head coach's responsibility."

England's midfield pairing of Henry Slade and rookie Ollie Lawrence struggled to get into the game but Jones had a simple reason to explain that.
"You've just got to look at the possession stats, they had 75 per cent possession, a penalty count of 10 to one. That's why the centres didn't touch the ball, it's the basics of rugby," he added.

"It is what it is, we get the players, we accept responsibility for the players, I accept responsibility for not getting players ready for this game."

Eddie Jones questioned whether Scotland could handle the "weight of expectation" and they provided the sweetest of answers by ending a 38-year wait for a win at Twickenham.

Time and again Scotland had failed to beat their fierce rivals in their own backyard, but that elusive victory finally came as they regained the Calcutta Cup on a wet Saturday evening in London.

Gregor Townsend's side dominated the Six Nations champions on the opening day of the tournament, winning 11-6 to leave England head coach Jones with a face like thunder.

Jones will be asking why his ill-disciplined side started the defence of their title with such a flat, insipid performance in a game that marked the 150th anniversary of rugby's oldest fixture

Scotland had produced a sensational fightback to draw 38-38 at the same venue two years ago, before being denied an astonishing victory late on.

They never looked like suffering more heartbreak on this occasion, Stuart Hogg leading by example as they won at the famous stadium for the first time since 1983 to leave England shellshocked.

Scotland certainly did not resemble a team who might be feeling the pressure as they bossed the game from start to finish.

The Red Rose, starting the tournament with a depleted pack, were guilty of indiscipline time and again, with referee Andrew Brace losing patience when he sent Billy Vunipola to the sin bin.

Finn Russell deservedly put Scotland in front with a penalty early on and almost set up a try for Duhan van der Merwe with a clever kick, but the leaping wing was unable to grab a high bouncing ball and touch down.

Van der Merwe was not to be denied soon after, fending off Mark Wilson's tackle to put Scotland 8-0 up on the half-hour mark, but Scotland suffered a blow when Russell was yellow-carded just before the break for tripping Ben Youngs.

The boot of Farrell reduced the deficit to two points at the interval, with Scotland surely heading to the dressing room thinking they should have been further ahead after being frustrated by resolute England defending.

Russell returned with Scotland still leading and they continued to boss possession, managing the game superbly, and the fly-half's second penalty put them 11-6 up before he missed another shot at goal.

A furious Jones marched from the stands to the touchline to try and turn the tide, replacing Jamie George and Youngs with Luke Cowan-Dickie and Dan Robson before the hour-mark.

The excellent Hogg kept them on the back foot with a sublime, mammoth kick into the corner - not for the first time - and England were warned over their penalty count again, but more desperate defence denied Scotland a second try as they continue to hammer at the door.

Lacklustre England's day was summed up when Jonny May knocked on under no pressure in the closing stages.

Hogg said Scotland felt ready to "create a little bit of history" and start a "new chapter" this weekend and, as they finally celebrated on the Twickenham turf, it was evident the Red Rose had failed to live up to expectations.

Scotland ended a 38-year wait for victory over England at Twickenham as a hard-working and industrious display earned a deserved 11-6 triumph and Calcutta Cup glory.

Not since 1983 had Scotland beaten their biggest rivals at the home of English rugby but the fired-up visitors outbattled and outplayed Eddie Jones' defending Six Nations champions.

Finn Russell and Stuart Hogg were the attacking catalysts in a match marking the 150th anniversary of the first meeting between these old foes.

Rookie Scotland centre Cameron Redpath showed why there is so much hype with a promising display in an empty stadium due to the coronavirus pandemic that delayed the finish to the 2020 championship.

England were without five forwards but even accounting for that the penalty count was much too high and they were lucky to only be 8-6 down at the break – Duhan van der Merwe crossing for the game's only try.

The end result is a third Calcutta Cup in four years for Scotland, who had previously lost nine in a row between 2008 and 2017.

England's ill-discipline allowed Russell to boot over an early penalty and an accumulation of infringements led to the sin-binning of Billy Vunipola for a high, albeit loose, arm on Scotland's number 10.

Buoyed by the extra man Hamish Watson was held up at the line by Jamie George and only a cruel bounce denied Van der Merwe from meeting Russell's expert kick.

Another bomb from Russell set in motion the move from which Van der Merwe bulldozed through Mark Wilson's tackle shortly after as Scotland had reward for their dominance.

But skipper Owen Farrell quickly kicked the hosts onto the board before Russell was binned for a crude trip on Ben Youngs and another three-pointer from England's captain brought the score within two.

The numerical disadvantage did little to curb Scotland's enthusiasm early in the second half and Russell kicked a routine penalty after Ellis Genge was harshly pinged for not attempting to bind with a low tackle.

Russell missed with another effort that he will feel he should have made but still England struggled to garner any momentum.

Stuart Hogg was also off target from the tee to make it a nervy ending, but the final whistle was met with shouts of joy from the visitors.

England's depleted pack lacks punch

There is a sense of deja vu for England who lost the opening match of their 2020 title-winning campaign to France.

The absence of Mako Vunipola and Kyle Sinckler clearly weakened a usually strong pack, while Joe Marler, Joe Launchbury and Sam Underhill were also absent. Without some key men, England lacked their usual set-piece prowess.

Russell and Hogg torment England

A year ago it looked as though Russell's international career may be over following a breakdown in the relationship with head coach Gregor Townsend.

His return to action for the 2020 finale was ended early due to an injury that ruled him out of the Autumn Nations Cup, but Scotland fans will be delighted their fly-half wizard has patched things up with Townsend after his magic helped seal a famous win.

He was helped by the brilliant Hogg, whose pin-point kicking and lightning-quick feet was a constant thorn in the side of an out-of-sorts England.

What's next?

England are at back at HQ as they aim to bounce back next Saturday when Italy visit Twickenham, the same day Scotland – who will now fancy a real crack at the title – host Wales at Murrayfield.

Scotland ended a 38-year wait for victory over England at Twickenham as a hard-working and industrious display earned a deserved 11-6 triumph and Calcutta Cup glory.

Not since 1983 had Scotland beaten their biggest rivals at the home of English rugby but the fired-up visitors outbattled and outplayed Eddie Jones' defending Six Nations champions.

Finn Russell and Stuart Hogg were the attacking catalysts in a match marking the 150th anniversary of the first meeting between these old foes.

England were without five forwards but even accounting for that the penalty count was much too high and they were lucky to only be 8-6 down at the break – Duhan van der Merwe crossing for the game's only try.

The end result is a third Calcutta Cup in four years for Scotland, who had previously lost nine in a row between 2008 and 2017.

Jayson Tatum savoured a "big team win" as the Boston Celtics condemned the Los Angeles Clippers to a second loss in three games.

His 34-point haul drove the injury-hit Celtics to their 119-115 success at Staples Center, with Kemba Walker adding 24 points.

In response, Kawhi Leonard led the Clippers with 28 points, five assists and 11 rebounds. That meant he exceeded 20 points for an eighth straight game, but he failed to make a three-pointer for just the third time this season, missing with his five attempts.

Tatum's points haul was his second highest of the season and included five three-pointers from 10 attempts.

The 2017 draft third overall pick was satisfied to see the team make up for their previous defeat, a loss to the Sacramento Kings on Wednesday.

"I think this is a good win, coming off a loss, down a few guys," Tatum said in a post-game news conference.

"But I think from my time being here, regardless of who we have playing, we always feel like we want to give ourselves a chance to win."

The Celtics improved to 12-9 for the season as the Clippers slipped to 17-7, having also lost narrowly to the Brooklyn Nets on Tuesday.

Tatum pointed to Boston delving into their squad, with Jaylen Brown and Marcus Smart both ruled out of the game.

"We've got a lot of talented guys on this team that work extremely hard. When you get your number called it's about being ready," he said.

"It was a big team win in that aspect and I'm proud of those guys."

Asked about taking on Leonard, Tatum responded: "I enjoy those matchups obviously. He's one of the best players, he's accomplished so much."

Daniil Medvedev won a marathon match against Alexander Zverev to send Russia into the final of the ATP Cup for the first time.

The world number four and reigning ATP Finals champion triumphed 3-6 6-3 7-5 at Melbourne Park in a match lasting just under two hours and 40 minutes.

That result clinched victory over Germany in the semi-final after Andrey Rublev had earler fought back in style from a set down to defeat Jan-Lennard Struff 3-6 6-1 6-2.

"We're really happy to get the win, that's the most important [thing," Medvedev said. "Tough matches [for] both of us. Both [Andrey and I] lost the first set. [It was] not easy, because we had two days off before the match. But happy we're in the final. That's the most important."

Zverev appeared in control after breaking to go 3-2 ahead in the second set after winning the first, but Medvedev reeled off four games in a row as the world number seven began to struggle with a lower back problem.

"When it's against Sascha and you are 6-3, 3-2, break down, many times you're going to lose a match," Medvedev said. "But I needed to keep my chances alive for the team first of all, for the country. I just tried to stay there, got a bit tight maybe. I just did my job and I'm really happy about it."

Russia will meet Italy in the final following their defeat of Spain, which was secured by Matteo Berrettini's straight-sets win over Roberto Bautista Agut.

After Fabio Fognini saw off Pablo Carreno Busta in three sets, Berrettini - who has beaten three of the top 13 players in the world without dropping a set in this tournament - won 6-3 7-5 to set up Sunday's Russia showdown.

"It's an unbelievable feeling," said a delighted Berrettini, who was absent last year as Italy failed to progress from their group in the inaugural staging of the event. "Last year I couldn't make it, so I'm really happy that the first time that I played we are into the final.

"I'm feeling good. I'm feeling pumped. I'm feeling great to play not just for me, but for my team and for Italy in general. That's what matters the most. I'm really looking forward to playing tomorrow."

SINNER TO FACE FAMILIAR FOE

There will be an all-Italian affair in the final of the Great Ocean Road Open, with Jannik Sinner to face Stefano Travaglia.

In-form Sinner clinched an impressive 7-6 (7-4) 4-6 7-6 (7-4) win over second seed Karen Khachanov, in a three-hour battle, after his compatriot beat Thiago Monteiro 6-3 6-4.

At the Murray River Open, Felix Auger-Aliassime will meet Dan Evans in the final as each look to secure a first ATP Tour title.

Auger-Aliassime needed only 61 minutes to beat Corentin Moutet, while eighth seed Evans required a minute less to ease past Jeremy Chardy.

Rafael Nadal has history in his sights, but Novak Djokovic stands in his way at an Australian Open he has almost made his own.

With Roger Federer absent from the year's first grand slam, all eyes in the men's draw will be on Nadal and Djokovic.

As the fight between the 'Big Three' continues as to who will finish their career with the most majors, Melbourne shapes as again playing a key part, particularly amid the ongoing uncertainty due to the coronavirus pandemic. After winning his 13th French Open last year, the equation is simple for Nadal. His success at Roland Garros drew him level with Federer on 20 majors, the most by a man all-time.

But with the GOAT debate sure to continue for decades to come, a second title in Melbourne would also lift the Spaniard into uncharted territory. Nadal has the chance to become the first man in the Open Era to win every grand slam at least twice. Federer and Djokovic are both missing a second crown at Roland Garros.

For all his dominance in Paris, that would add another feather to the cap for 34-year-old Nadal. Most of Federer's major success has come at Wimbledon (eight titles), while Djokovic's has been at the Australian Open (also eight titles) – both establishing men's records at those tournaments. Nadal has been runner-up four times in Melbourne since his only title in 2009, while he has reached at least the quarter-finals in the past four years.

But just as Nadal, who is dealing with a back injury ahead of the tournament, stands in the way at the French Open, he will need to get past Djokovic – or have some luck – in Australia.

The Serbian has a 75-8 win-loss record at the tournament, including winning the past two titles. He has won the crown every time he has reached the semi-finals. Djokovic's previous blip in Melbourne came in 2017 and 2018, surprisingly beaten by Denis Istomin (second round) and Chung Hyeon (fourth round) respectively.

A year younger than Nadal, Djokovic is a 17-time grand slam champion, and he has made no secret of his desire to hold the record for most majors won by a man. Djokovic and Nadal have claimed nine of the past 10 majors, although the other one came recently as Dominic Thiem clinched last year's US Open, where the Spaniard and Federer were absent.

With preparations impacted by COVID-19, perhaps Thiem, Daniil Medvedev, Stefanos Tsitsipas, Alexander Zverev or Andrey Rublev could threaten as the wait goes on for a changing of the guard in men's tennis.

But all eyes are unsurprisingly on Nadal and Djokovic as history again beckons.

Garbine Muguruza continued her impressive form to book a meeting with Ash Barty in the Yarra Valley Classic final.

Muguruza, the Spanish sixth seed at the WTA 500 event, crushed Marketa Vondrousova 6-1 6-0 on Saturday.

The two-time grand slam champion has lost just 10 games in four matches on her way to the final.

Muguruza lost just eight points on serve against Vondrousova while converting five of 11 break points.

She will meet Barty in the final after the Australian benefited from Serena Williams' withdrawal as the 23-time grand slam winner deals with a shoulder injury.

Naomi Osaka and Victoria Azarenka also withdrew on Saturday from the Gippsland Trophy and Grampians Trophy respectively.

At the Grampians Trophy, Anett Kontaveit was given a passage into the semi-finals, where Maria Sakkari awaits after her 6-4 6-2 win over Angelique Kerber.

Jennifer Brady and Ann Li will meet in the other semi after wins over Barbora Krejcikova and Sorana Cirstea respectively.

Elise Mertens will play the Gippsland Trophy final after Osaka's withdrawal with the Belgian to face Kaia Kanepi, who overcame Ekaterina Alexandrova 6-3 7-6 (8-6) to reach her first WTA decider since 2013.
