In this world, nothing can be said to be certain, except death and taxes – a statement largely true until Rafael Nadal emerged on the scene and made the French Open his own.

Since breaking through for his first Roland Garros triumph in 2005, only three other men – Roger Federer, Stan Wawrinka and Novak Djokovic – have managed to interrupt Nadal's dominance in Paris.

Nadal has won 13 French Open men's singles titles, seven more than any other player in the Open era (Bjorn Borg, six) heading into this year's edition.

Despite being seeded third, it would take a brave person to bet against defending champion Nadal adding to his mammoth and unprecedented haul in the French capital, where the second grand slam of the year gets underway on Sunday.

On the women's side, defending champion Iga Swiatek is looking to follow in the footsteps of Belgian great Justine Henin.

As all eyes shift to Court Philippe Chatrier and its surroundings, Stats Perform looks at the numbers behind this year's slam, using Opta data.

The 'King of Clay'

Nadal will open his title defence against Australian Alexei Popyrin. Since 2000, only Nadal (13) and Gustavo Kuerten (two) have won the French Open more than once.

The 34-year-old swept aside world number one Djokovic in straight sets last year for his fourth consecutive French Open crown and 20th slam trophy, equalling Roger Federer's all-time record. Nadal maintained his stranglehold on the major, having not dropped a set throughout the fortnight. Only three players have previously won the French Open without losing a single set: Ilie Nastase in 1973, Bjorn Borg in 1978 and 1980 and Nadal in 2008, 2010, 2017 and 2020.

Nadal is the only player to have won the same slam more than 10 times. He has lost just two of the 102 matches played in Paris (excluding walkovers), losing to Robin Soderling in the 2009 fourth round and Djokovic in the 2015 quarter-finals, while has won each of the last 30.

The record for most slam titles on the men's circuit will also be up for grabs, with Nadal and the returning Federer seeking to snap their tie.

In the last 25 years, the number one seed has won the French Open on only five occasions – Nadal (2018, 2014 and 2011), Djokovic (2016) and Kuerten (2001). It does not bode well for top seed and 18-time major champion Djokovic, who is looking to close the gap on foes Nadal and Federer.

Australian Open champion Djokovic, who will face Tennys Sandgren in the first round, has reached the final in seven of the last 10 slams he contested, claiming six titles. However, the Serbian star has only featured in five French Open deciders (W1 L4) – fewer than in any of the other three major tournaments.

Declining Federer, Nadal challengers?

The French Open will be a welcome sight for tennis fans as Swiss great Federer, who has not played a slam since the 2020 Australian Open due to his troublesome knee and the coronavirus pandemic, makes his comeback.

Seeded eighth ahead of his opener against Denis Istomin, 2009 French Open champion Federer has only contested nine slam finals over the last 10 years (W4 L5) after reaching that stage in 22 major events in the previous decade (W16 L6). Since the beginning of 2016, the 39-year-old has only taken part in one French Open, in 2019, where he reached the semi-finals.

Daniil Medvedev has been flirting with a breakthrough slam triumph. The second seed is a finalist at the Australian Open (2021) and US Open (2019). Medvedev has reached the semi-finals in two of his most recent three appearances at a grand slam after going further than the fourth round in only one of his previous 13 major tournaments. However, the Russian has lost in the first round in each of his four Roland Garros appearances.

US Open champion and fourth seed Dominic Thiem has played two finals at Roland Garros (2018 and 2019) – more than in any other slam – but lost both of them against Nadal. He has won 80 per cent of his games at the French Open, his best win rate in any of the four majors.

Andrey Rublev is the only player to have taken part in the quarter-finals during each of the past three grand slams, including the 2020 French Open. But the seventh seed – who fired down 53 aces at Roland Garros last year, at least 14 more than any other player – is yet to progress further than that round.

Aslan Karatsev enjoyed a fairy-tale run at Melbourne Park in February, the Russian qualifier making it all the way to the semi-finals. Only one qualifier has reached the semi-final stage at the French Open: Filip Dewulf in 1997.

Iga in 14-year first?

Having never progressed beyond the fourth round of a major, Polish teenager Swiatek broke through for her maiden slam title via the French Open last year, upstaging Sofia Kenin.

The 19-year-old Swiatek – who will return as the eighth seed in her defence, starting against Kaja Juvan – could become the first woman to win consecutive titles at Roland Garros since Henin in 2005-2007 (three in a row). Only three players have won multiple titles in the women's tournament at the French Open in the 21st century: Henin (four), Serena Williams (three) and Maria Sharapova (two).

Swiatek could claim the French Open and Rome's Internazionali d'Italia in the same campaign. Only Serena Williams (2002 and 2013), Sharapova (2012), Monica Seles (1990), Steffi Graf (1987) and Chris Evert (1974, 1975 and 1980) have achieved the feat previously.

Swiatek celebrated slam glory in the absence of world number one and defending champion Ash Barty in 2020. No player has won more games on clay this season than Australian top seed Barty and Veronika Kudermetova (both 13).

Only Barty (three) has won more titles than third seed Aryna Sabalenka (two) in 2021 – the Belarusian is one of two players currently ranked in the top 20 in the WTA yet to reach a major quarter-final, alongside Maria Sakkari.

In a field also including four-time slam champion and reigning Australian Open winner Naomi Osaka – the second seed – Sabalenka could become only the third woman to win the Madrid Open and French Open in the same season after Serena Williams in 2013 and Sharapova in 2014.

As for fourth seed Kenin, she could be just the fourth American player to reach back-to-back Roland Garros finals, after Serena Williams (2015-16), Martina Navratilova (1984-1987) and Evert (1973-1975, 1979-80 and 1983-1986).

All eyes on Serena

The queen of WTA tennis for so long, Serena Williams is one slam success away from matching Margaret Court's record of 24 major singles championships. But the 39-year-old has been stuck on 23 since reigning supreme at the Australian Open in 2017.

While the French clay is not one of her favourite surfaces, it could be the scene of a remarkable achievement following a lengthy wait.

Roland Garros is where Williams has the lowest winning percentage (84 per cent) and where she won the fewest titles (three, at least half as many as the other slams).

Williams won her maiden French Open in 2002 and could hoist the trophy aloft 19 years after her first success in Paris. The longest span between two majors wins for a single player in the Open era is already held by Williams (15 years between 1999 and 2014 at the US Open).

Irina-Camelia Begu awaits the seventh seed in the first round.

Lyon Open top seed Dominic Thiem was stunned in straight sets by Cameron Norrie in the last 16 on Thursday for the "biggest win" of the Briton's career.

Thiem was handed a bye to this stage and fell at the first hurdle on a day of upsets, the world number four sending down four double faults and losing serve three times as he lost 6-3 6-2.

Norrie now has 10 victories on clay in 2021, compared to seven before this year, and will face qualifier Arthur Rinderknech – a surprise 6-7(7) 6-2 7-5 winner against Jannik Sinner – in the quarters.

"I'm so pleased to win. It's the biggest win of my career and my highest-ranked win," Norrie, who had never previously beaten a top-five opponent, said in his on-court interview. 

"It's such a beautiful day in Lyon. I couldn't be happier to get the win today and to get another match on the clay before Roland Garros."

Third seed Diego Schwartzman also exited the competition on Thursday with a 6-3 7-5 defeat to Richard Gasquet, who eased over the line despite letting two match points slip.

Stefanos Tsitsipas is now the strong favourite to triumph in France after starting his campaign with a convincing 6-1 6-4 victory over Tommy Paul.

Yoshihito Nishioka upset Gael Monfils 4-6 6-3 7-6(2) in an impressive comeback victory and now awaits Tsitsipas in the last eight.

At the Geneva Open, rising star Casper Ruud kept his momentum going with a 2-6 6-1 6-4 win over Dominik Koepfer to make it 12-4 on clay this season.

Ruud recovered from a sloppy first set by holding his serve in the following two sets to reach his fourth successive clay court semi-final on the ATP Tour.

Next up for the third seed is a meeting with Pablo Andujar, who beat youngster Dominic Stephan Stricker 4-6 6-4 6-4.

Elsewhere, Laslo Djere overcame Fabio Fognini 6-3 6-7(2) 6-1 to reach the quarter-finals and will face Denis Shapovalov later on Thursday after the Canadian recovered from a set down to beat Marco Cecchinato 6-7 7-5 6-1.

The winner of that match will meet Pablo Cuevas, the Uruguayan having ended Grigor Dimitrov's run with a battling 7-6 6-3 win.

Alexander Zverev can see his rivalry with Dominic Thiem continuing for many years after he came out on top in their latest duel at the Madrid Open.

The German followed up his famous win over home favourite Rafael Nadal by defeating Austria's Thiem 6-3 6-4 in the semi-final on Saturday.

Zverev, who won this event in 2018, will meet either Casper Ruud or Matteo Berrettini in the final.

Thiem had won the last four meetings between the two, including in last year's Australian Open semi-final and the US Open final, where he came from two sets down to win in an incredible fifth-set tie-break.

Zverev said after his victory over Nadal that he would be thinking about that crushing loss in New York prior to his meeting with Thiem.

And he was able to gain a small measure of revenge for those recent grand slam defeats in the Spanish capital.

"We have had some fantastic matches," said Zverev. "We have played the biggest matches in the world. We have played Masters 1000 finals, we have played grand slam finals and [the rivalry] is still developing.

"It is still going to go on for a few more years. Hopefully we will play a few more amazing matches. It feels very [sweet to win], it is a rivalry where he kicks my a** most of the time!

"It is going to mean a lot to me [if I can win the final].

"I am definitely looking forward to playing another big final and I hope I can turn it my way this time."

A solitary break of serve was enough for Zverev to claim the opening set.

He recorded two breaks in the second to go 4-1 up and although Thiem got one strike back, two more holds gave Zverev - who forced 11 break points to his opponent's two - a big victory.

The world number six is yet to drop a set this week but has lost his last three Masters 1000 finals going into his latest attempt on Sunday.

Thiem, meanwhile, has reached the Madrid Open semi-finals in four straight years but it still waiting for his first triumph at the tournament.

Rafael Nadal saw off Alexei Popyrin to reach the Madrid Open quarter-finals on a day that saw Daniil Medvedev and Stefanos Tsitsipas suffer surprise defeats.

World number two Nadal, chasing a record-extending sixth title on home soil, advanced 6-3 6-3 in a time of one hour and two minutes on Thursday.

Popyrin, playing in his first last-16 match at a Masters 1000 event, broke Nadal in the sixth game of the opening set but the Spaniard otherwise looked comfortable.

Nadal converted four of his six break points to advance through to the last eight for a 15th time, where Alexander Zverev awaits.

"It was difficult," Nadal said in his on-court interview. "The court today was slippery, it was very fast, very dry conditions. The ball was flying a lot. The beginning was super tough. 

"He was hitting every ball and hitting the spots. I'm happy with the victory. It was an important victory, he came here playing well. Every match is tough."

Zverev, who won the competition in 2018, beat British number one Dan Evans 6-3 7-6 (7-3) to set up a meeting with Nadal

However, second and fourth seeds Medvedev and Tsitsipas saw their participation come to an end at the hands of Cristian Garin and Casper Ruud respectively.

Medvedev, who is still yet to reach the quarters in Madrid, lost the only break of serve in the third game of the opening set but recovered by taking the second set in a tie-break.

Garin dominated the deciding set, the world number 25 breaking Medvedev twice and, after a short delay to fix a broken net, advanced 6-4 6-7 (7-2) 6-1.

Tsitsipas, who held championship point against Nadal in the Barcelona Open final, failed to break Ruud on a single occasion as he fell 7-6 (7-4) 6-4.

Alexander Bublik is next up for Ruud after beating Aslan Karatsev 6-4 6-3, while Matteo Berrettini - 7-6 (7-4) 6-4 winner against Federico Delbonis - will meet Garin.

Also vying for a place in the semi-finals are John Isner and Dominic Thiem, who are set to face off after beating sixth seed Andrey Rublev and Alex de Minaur respectively.

Dominic Thiem surged to an emphatic victory on his return to the ATP Tour at the Madrid Open.

US Open champion and two-time Madrid Open runner-up Thiem was playing his first match in nearly two months on Tuesday, having taken a break to recharge.

But it did not take him long to get back into the groove, the third seed easing through his second-round match with American qualifier Marcos Giron 6-1 6-3 at the ATP 1000 event.

"I was uncertain how things will be going. The game worked out very well in the past days of practice, but I was always practising on the outside courts which are faster, which are smaller, so I was just not sure how it was going to be in the match," Thiem said.

"But there were some things which I think made [the match] a little bit easier after such a long time, especially the conditions in Madrid, which are great for me.

"Then [I have] amazing memories on this court, where I already played probably some of the best matches of my career. I think that's why things worked out quite well tonight."

Next for Thiem in the last 16 is Alex de Minaur, who was leading 6-2 3-0 when Lloyd Harris retired from their match.

It was a largely strong day for the seeded players in the Spanish capital, home hope and ninth seed Roberto Bautista Agut beating Marco Cecchinato 6-2 6-7 (3-7) 7-5 in a first-round clash.

Andrey Rublev – the sixth seed – came from a set down to beat Tommy Paul 6-7 (5-7) 6-3 6-4 and eighth-seeded Italian Matteo Berrettini joins him in the last 16 after defeating compatriot Fabio Fognini 6-3 6-4.

Jannik Sinner, who is seeded 14th, won in the first round after Guido Pella retired in the second set. However, four seeds did tumble out of the draw.

Felix Auger-Aliassime was thrashed 6-1 6-4 by Casper Ruud in the first round and his Canadian compatriot Denis Shapovalov was beaten 6-4 5-7 6-4 by Alexander Bublik in their second-round encounter.

Miami champion Hubert Hurkacz suffered a second successive second-round exit, the 12th seed defeated 5-7 7-6 (9-7) 6-3 by John Millman in a match that went the distance having lost at the same stage in Monte Carlo.

Top seed Dominic Thiem was beaten in straight sets in the second round of the Dubai Tennis Championships by Lloyd Harris.

The reigning US Open champion, given a bye for the first round, lost 6-3 6-4 to his South African opponent, who sits 77 places further down the ATP rankings.

The Austrian has endured a difficult start to 2021. He lost in straight sets to Grigor Dimitrov in the last 16 of the Australian Open and was beaten by Roberto Bautista Agut in the quarter-finals in Doha.

It was a first win over a top-five player for Harris, who was not once taken to deuce on serve during their 72 minutes on court.

"I'm super, super happy with that win. [He is] by far the highest-ranked player I have beat," said Harris. "I look up to Domi a lot so, for me, it is a special feeling. I am really happy. Just the fact that I am playing good tennis, match in, match out now is giving me a lot of confidence.

"I was serving really well. I don't think I faced any break points. I took control of those games and [in] one or two games on his serve, I gave myself a good look. I played some of the important points very well. I am very proud of that."

While Thiem is struggling for form, things are looking far better for Andrey Rublev, who beat Emil Ruusuvuori 6-4 6-4 to stretch his winning streak at ATP 500 events to 21 matches.

The world number eight, who will face Taylor Fritz in the next round, equalled Andy Murray for the second-best winning run at this level of the Tour. Roger Federer (28) holds the record.

Third seed Denis Shapovalov beat Jan-Lennard Struff for the loss of just four games, while Bautista-Agut advanced after opponent Matthew Ebden retired in the first set.

Fifth seed David Goffin was beaten in straight sets by Kei Nishikori, who recorded just his third victory of the year.

Karen Khachanov and Jannik Sinner each advanced after three-setters, while Marton Fucsovics and Aslan Karatsev were also taken the distance before progressing.

Hubert Hurkacz, Lorenzo Sonego, Dusan Lajovic, Aljaz Bedene and Filip Krajinovic also won on Tuesday.

Dominic Thiem is relishing Roger Federer's return to action, with the duo taking part in this week's Qatar Open.

Federer has spent the last 13 months out, having elected to take 2020 off – following last year's Australian Open – to undergo two knee operations.

The 40-year-old will compete in Doha this week, returning to play in an event where he has enjoyed plenty of success down the years, winning the tournament three times.

Last year's US Open champion Thiem, who has moved above Federer in the world rankings during the Swiss' absence, will also be in action in Qatar, and is thrilled to see the 20-time grand slam winner make his comeback.

"We are rivals, and of course we want to beat each other in the tournament, [but] I still really love to watch him play tennis," said top seed Thiem, who was speaking to Laureus Sport after his nomination for Breakthrough of the Year.

"[He] looks so nice, the way he plays, the way he approaches the game of tennis.

"On the one hand, I'm also a big fan of his still, and that's why I really love that he's back and that I can watch him again. That's what pretty much everybody is thinking, and I hope that he's coming back strong, as well."

Federer and Thiem have met seven times, with the Austrian holding the advantage, with five wins to his name against the former world number one.

Thiem, a semi-finalist in Doha in 2018, has not played since he lost to Grigor Dimitrov at the Australian Open in mid-February, and the world number four is hoping to make a fast start when he takes on Aslan Karatsev in round two.

"The [Doha] draw is unbelievably strong, so [you] never know what's [going to] happen, but I just try to have a good start and to be there on a good level from the very first point," said Thiem.

"It's going to be my first tournament and [my] first match [in almost] a month, since [a] pretty devastating loss at the Australian Open.

"I needed some time to digest everything, to analyse everything [and] to settle down a little bit. Now it's time to focus on new things. The tournament in Doha is the first chance to play better again, to get good results, to get confidence and to forget a pretty tough start of the season."

Dominic Thiem's bid to reach back-to-back Australian Open finals was dashed by Grigor Dimitrov as the US Open champion surprisingly crashed out in the round of 16.

Thiem lost a thrilling final to Novak Djokovic in last year's Melbourne Park decider before breaking through for his maiden grand slam title at Flushing Meadows later in 2020.

But Thiem failed to secure another second-week berth in Melbourne, where the third seed was stunned 6-4 6-4 6-0 by former world number three Dimitrov on Sunday.

Thiem was aiming to reach the Australian Open quarter-finals for the second time and become the second Austrian man to feature in the quarters in Melbourne on multiple occasions after Thomas Muster (1989, 1994 and 1997).

The 27-year-old Thiem was also bidding to reach his ninth slam quarter-final and equal Muster's record for most major last-eight appearances by any Austrian – male or female.

However, Thiem – who rallied from two-sets-to-love down to top Nick Kyrgios in the previous round – was no match for Dimitrov behind closed doors on Rod Laver Arena amid a coronavirus lockdown in Victoria.

Both players hit 25 winners, but Dimitrov only tallied 18 unforced errors to Thiem's 41 following just over two hours on court.

Dimitrov progressed to his fourth Australian Open quarter-final, extending his record for most last-eight appearances at Melbourne Park by a Bulgarian player – man or woman.

An Australian Open semi-finalist in 2017, Dimitrov will now contest his sixth grand slam quarter-final – the 29-year-old is third for most quarter-final appearances by a Bulgarian player, behind Manuela Maleeva (nine) and Katerina Maleeva (seven).

Dominic Thiem came from behind to edge Nick Kyrgios in a five-set epic in the Australian Open third round on Friday.

Thiem, last year's runner-up in Melbourne, fought back to win 4-6 4-6 6-3 6-4 6-4 on John Cain Arena.

The Austrian third seed was unable to match Kyrgios' energy levels early on, but the reigning US Open champion responded to reach the fourth round of a major for the 15th time in his career.

Thiem, who will face Grigor Dimitrov in the fourth round, was in impressive form after his slow start, finishing with 57 winners and just 28 unforced errors.

Kyrgios was getting the crowd – full of energy ahead of Victoria going into a five-day lockdown from Saturday due to coronavirus concerns – involved from the warm-up, while Thiem appeared flat.

An underarm ace saw Kyrgios take a two-sets-to-love lead as he looked in control before Thiem responded.

Coming from 15-40 down in the opening game of the third set, Thiem won 20 consecutive points on serve.

Kyrgios steadied and held after a marathon game to begin the fourth set, but he could not deny Thiem – who continued to hold serve comfortably – in the ninth as the Austrian broke with a cross-court forehand pass.

A point penalty for ball abuse appeared to bring Kyrgios to life, but Thiem saved a break point and served out the set.

The crucial and only break of the fifth set came for Thiem in the seventh game after several fine returns and he closed out his victory with a spectacular backhand winner down the line.

Nick Kyrgios has the weapons to overcome the "super physical" Dominic Thiem at the Australian Open on Friday.

The eccentric Australian continued to excite at Melbourne Park with a five-set win over Ugo Humbert in the second round, saving two match points.

Kyrgios, 25, is into the third round of a grand slam for the 15th time in his career, but it has been a difficult hurdle for him to cross. He is 6-8 in the third round of majors, although three of those wins – and just one loss – have come at the Australian Open.

While he has all the weapons, Kyrgios faces third seed Thiem, the US Open champion and last year's runner-up in Melbourne.

"He's probably one of the most physical guys on tour. He's an extremely good player. I have actually seen him progress. He's a bit older than I am. I actually saw him in juniors and then I saw him struggle for a couple years, futures, challies, and then to see him get to the top of the game. It's been actually pretty cool to see him develop and finally find what he needs to do to win matches," Kyrgios said about Thiem after overcoming Humbert.

"He trains like an absolute animal. He's consistent every day. And I actually have a lot of respect for him. I think his style of tennis is not easy to play. He's super physical, but I'm not even thinking about it. Like, I'm just hurting thinking about playing him right now."

He added: "Whatever happens against Thiem happens. I'm going to go out there, serve, play with instinct, and if it's enough, it's enough. If it isn't, I'm all right with that."

With much of the talk at the year's first major focused on the fast courts, Kyrgios' serve will be vital.

The Australian has seen 50 per cent of his first serves in the opening two rounds go unreturned, with 44 aces. He has also served at 72 per cent and won 81 per cent of the points when his first serve has gone in.

Thiem has recorded wins over Mikhail Kukushkin and Dominik Koepfer to begin the tournament, winning 13 of 27 return games. Kyrgios has won eight of 42 return games.

Kyrgios has been among the men more willing to serve and volley to begin the event, playing 26 such points and winning 16. He has also won 39 of 55 net points, while Thiem is an impressive 31 of 36.

Novak Djokovic is among those who have talked about the fast courts at Melbourne Park this year, and the world number one said that would suit the big servers. Thiem said he had never played on courts as fast at a grand slam so far in his career.

"I prefer last year's courts, if I could choose. It's pretty fast, as I said the days before. It's probably one of the fastest grand slam tournaments I've played so far," he said. "Well, we have to get used to it, yes. But if I have to choose, I would choose the last year's condition."

The opportunity is there for the big-hitting Kyrgios, but he will need to be at his best.

Novak Djokovic admitted there was plenty of room for improvement after coming through a "difficult spot" at the Australian Open, where Nick Kyrgios thrilled the crowd with an impressive comeback.

Top seed Djokovic was made to work for his 6-3 6-7 (7-3) 7-6 (7-2) 6-3 triumph against Frances Tiafoe as he reached the third round in Melbourne. 

Kyrgios is also through, albeit he even surprised himself by rallying from the brink of defeat to knock out 29th seed Ugo Humbert in the evening session. 

Stan Wawrinka was on the wrong of an upset on Wednesday, but there were no such problems for fellow seeds Dominic Thiem, Alexander Zverev, Diego Schwartzman and Milos Raonic. 

Meanwhile, Denis Shapovalov and Felix Auger-Aliassime will have to put their friendship to one side when they face each other next, the former setting up the all-Canadian clash by beating Bernard Tomic in three sets.

'PASSIVE' DJOKOVIC STILL MAKING PROGRESS

In the first meeting between the pair, the impressive Tiafoe went toe-to-toe with Djokovic on Rod Laver Arena.  

The 23-year-old American's performance – coupled with the Melbourne heat – made the eight-time Australian Open champion sweat, albeit Djokovic felt he could have made life easier for himself.

"I was at times not feeling my timing as well as I normally am. Credit to him. I think he has managed to come out with a great performance and quality of tennis. He put me in a difficult spot," he said. 

"I had my chances early in the second set. If I broke him there, maybe the course of the match would be different.   

"But again, he was holding his serve very well. I was not really using my break-point chances very well. At times I was too passive. Just wasn't feeling the ball today as well as I normally do." 

Next up for Djokovic is another player from the United States in the form of Taylor Fritz, who ousted compatriot Reilly Opelka in a five-set battle.

IN THE NICK OF TIME

Kyrgios described his clash with Humbert as "one of the craziest matches I've ever played" after prevailing 5-7 6-4 3-6 7-6 (7-2) 6-4 - much to the delight of an enthralled audience who watched the drama unfold on John Cain Arena.

The Australian smashed a racket, lost his cool with umpire Marijana Veljovic over a faulty net cord sensor and had to save a pair of match points before eventually coming out on top in a see-saw battle.

"I just remember, down that end, when I was a couple of match points down, I don't know what was going on," Kyrgios - who dropped to his knees after sealing victory - said in his on-court interview.

"If you were inside my head, there were some dark thoughts in there. But I live to fight another day and hopefully I can continue to play good tennis in front of you guys."

His reward is a clash with Thiem, the third seed having dismissed the challenge of German Dominik Koepfer in straight sets as he dropped just six games.

STAN-D AND DELIVER

Wawrinka appeared on course to survive a serious scare when he rallied from two sets down against Marton Fucsovics, but the Swiss was unable to seize on the chances that came his way in a tense tie-break. 

Fucsovics had needed over four hours to overcome wild card Marc Polmans in the previous round and, once again, found a way to get over the finishing line at the end of a Melbourne marathon. 

The Hungarian trailed 6-1 during the decisive breaker, yet hit back to stun the 17th seed 7-5 6-1 4-6 2-6 7-6 (11-9). For Wawrinka, there was frustration at the missed opportunities, albeit he also praised his conqueror. 
  
"From 6-1 up, I started to hesitate a little bit in the way I was playing," he said. "I wanted to put the ball maybe too much in and I [was] not going completely for my shots and that's when I started to miss a little bit and it helped him to come back in the match.  

"He was fighting well, he's a tough player, he's a good player and he deserved to win." 

Australian Open champion Novak Djokovic could face Dominic Thiem in a mouth-watering semi-final after being handed a tough path to success at Melbourne Park, where Serena Williams will continue her quest for a 24th grand slam singles title.

The Australian Open draw took place on Friday, with world number one Djokovic set to play Frenchman Jeremy Chardy in the opening round of the year's first major tournament.

Amid coronavirus concerns in Melbourne, where Swiss great Roger Federer is absent, Djokovic has set his sights on a ninth crown and 18th major success, but the top seed's title defence is far from straightforward.

Djokovic could face Gael Monfils (fourth round) and sixth seed Alexander Zverev (quarter-final) en route to a possible semi-final against US Open champion and third seed Thiem.

The Serb overcame Thiem in a five-set thriller in last year's Australian Open final, before the latter broke through for his maiden major trophy at Flushing Meadows.

Djokovic could then meet second seed and 20-time major champion Rafael Nadal in a blockbuster final – he blitzed the Spanish superstar in the 2019 Australian Open decider but lost in three one-sided sets in their previous meeting in the French Open final.

Nadal will go head-to-head with another Serb in the first round – Laslo Djere – while Stefanos Tsitsipas could await in the quarters, with 2019 US Open final opponent Daniil Medvedev also on the same side of the draw.

Meanwhile, Williams' bid for a record-equalling 24th slam will begin against German Laura Siegemund.

The 39-year-old Williams has been stuck on 23 majors since winning the Australian Open in 2017 – losing finals at Wimbledon (2018 and 2019) and the US Open (2018 and 2019).

World number one and local hope Ashleigh Barty will meet Montenegro's Danka Kovinic in round one and defending champion Sofia Kenin faces Australian wildcard Maddison Inglis.

The last 16 could see Williams clash with Aryna Sabalenka, Barty meet Petra Martic, Kenin tackle Johanna Konta and three-time major champion Naomi Osaka do battle with last year's runner-up Garbine Muguruza.

Novak Djokovic continued his perfect record at the ATP Cup to help Serbia beat Canada in their opening tie.

The world number one won all eight of his rubbers in the 2020 tournament and made a fine start to this event by battling to a 7-5 7-5 win over Denis Shapovalov in Melbourne.

Milos Raonic had earlier put Canada in front when he beat Dusan Lajovic 6-3 6-4, meaning Djokovic had to return for a decisive doubles clash alongside Filip Krajinovic. 

The Serbians prevailed, winning 7-5 7-6 (7-4) against Shapovalov and Raonic.

"Filip Krajinovic was the key," Djokovic said after the doubles triumph extended his undefeated run to 10. 

"The way he played is phenomenal. He came out with very solid returning. He found his serve, great rhythm. He just played some really key shots in the second set when we needed it the most."

Of his singles win, Djokovic added: "It was a very close match. Playing Shapo is always a great challenge on hard courts. 

"He's such a dynamic, explosive player; very talented. I thought we played on a very high level, so I'm really pleased with how I've started the season.

"This is the best way to kickstart the season, playing for your country.

"We don't get to see crowds in the tennis stadiums these days so much, so it's definitely a blessing. I'm really grateful to see you guys here in the stands."

SPAIN WIN WITHOUT NADAL

Defending champions Spain were without Rafael Nadal for their tie against Australia, but they still prevailed.

Pablo Carreno Busta had few problems seeing off John Millman 6-2 6-4.

And Roberto Bautista Agut ensured the tie was won before the doubles by emerging triumphant in an entertaining encounter with Alex de Minaur, which the Spaniard won 4-6 6-4 6-4.

Nadal, who is battling a back problem, hopes to return on Thursday when Spain take on Greece.

Elsewhere, Austria fell to a 2-1 loss against Italy, as US Open champion Dominic Thiem struggled.

After team-mate Dennis Novak had superbly beaten Fabio Fognini, world number three Thiem fell to a surprise 6-2 6-4 loss against Matteo Berrettini, with Austria going on to lose the decisive doubles.

Andrey Rublev and Daniil Medvedev beat Guido Pella and Diego Schwartzman respectively as Russia produced an impressive performance to beat Argentina.

Elsewhere, at the Murray River Open, Nick Kyrgios made a winning start to his comeback after a year out of action.

He did not have it easy against the unheralded Frenchman Alexandre Muller, but salvaged a 3-6 6-4 7-6 (7-4) victory to book a second-round meeting with fellow Australian Harry Bourchier.

Serena Williams and Rafael Nadal agreed it was great to be playing in front of busy grandstands again as tennis stars emerged from lockdown in Australia.

The women's and men's tennis tours have been contested largely behind closed doors over the past year, and a number of tournaments, most notably Wimbledon, have been cancelled due to the COVID-19 crisis.

The Australia public has given a cautious welcome to the arrival of the world's leading players, who have been quarantining in hotel rooms for much of the past fortnight, only allowed to briefly leave in order to train.

Ahead of the Australian Open, which begins on February 8 in Melbourne, Williams and Nadal are among a star-studded set of players who travelled to Adelaide to feature in the 'A Day at the Drive' exhibition event.

They both scored victories on Friday, with Williams defeating US Open champion Naomi Osaka 6-2 2-6 10-7 and Nadal snatching a 7-5 6-4 win over Dominic Thiem.

The delight in both at seeing crowds at a tournament was plain, with Williams saying in an on-court interview: "Thanks everyone for having us. We haven't played in front of a crowd in over a year. It's been a really long time."

In fact, it has not quite been a full year since the tours locked down initially, as it was early March when most tournaments began to be called off, with crowds frozen out.

Williams said the reception made the difficult past fortnight, being hidden away from the world, worth the strain for the players.

"This is really cool and then for having us and trusting us with your laws was great," said the 23-time grand slam winner. "We were so excited to be here and it's worth it."

Nadal said he was "super happy" to still be playing at the highest level and back in front of Australian crowds.

The pandemic has been carefully managed to the point where very few have the virus and it is considered safe to allow crowds into sporting events in the country.

Nadal said: "Hopefully this situation will go away quick and we will be able to enjoy fans on court [around the world].

"We're super excited to have fans at the Australian Open and today."

That optimism and excitement was shared by men's world number one Novak Djokovic, who played just one set against Jannik Sinner due to a problem with blisters on his right hand.

Eight-time Australian Open champion Djokovic told fans: "Thank you so much for coming out and making our day and making our year.

"We didn't play in front of this much crowd for 12 months. This is definitely something very special.

"It wasn't easy, obviously, with 14 days being constrained in the room and a few hours to train, but at the end of the day it was worth it because you guys made it very special today for us."
