Novak Djokovic remained on course for a record-extending seventh Paris Masters title after booking his quarter-final place with victory over Karen Khachanov.

The six-time champion avenged his defeat by Khachanov in the 2018 Championship match by running out a commanding 6-4 6-1 winner.

That gave Djokovic his 11th straight victory in the French capital, where he is unbeaten since that 2018 defeat, while he has also won each of his last 11 Tour-level matches.

The Serbian, who has triumphed in Tel Aviv and Astana during that streak, set up a last-eight clash with Lorenzo Musetti after the Italian came from behind to stun third seed Casper Ruud 4-6 6-4 6-4.

The Naples champion recorded his maiden top-five victory at the seventh attempt, while he hit 37 winners to advance to his first ATP Masters 1000 quarter-final.

Meanwhile, world number one Carlos Alcaraz won five out of seven break points as he breezed past Grigor Dimitrov 6-1 6-3 to reach the last eight in Paris for the first time.

There, he will play Holger Rune after the Stockholm champion defeated seventh seed Andrey Rublev in straight sets.

Fifth seed Stefanos Tsitsipas overcame Corentin Moutet 6-3 7-6 (7-3) to reach his 14th quarter-final of the season, where he will face Tommy Paul after the American denied Pablo Carreno Busta 6-4 6-4.

Felix Auger-Aliassime was a commanding 6-1 6-3 victor over Gilles Simon. The eighth seed will take on Frances Tiafoe, who defeated Alex De Minaur 6-3 7-6 (7-5).

Novak Djokovic and Casper Ruud were made to work hard for victory in their opening matches at the Paris Masters on Tuesday.

For Djokovic, a 10th win in a row came in an absorbing battle with his Paris-born American opponent Maxime Cressy, who displayed a typically aggressive approach on serve, with 15 aces and 10 double faults overall.

Djokovic was strong on his own delivery, however, with the Serbian losing just six points on serve and not facing a break point on his way to a 7-6 (7-1) 6-4 victory.

"I'm happy with the way I played," Djokovic said. "When chances were presented, I was able to use them, even though I did have some missed break points.

"But it was very challenging, first match with a guy who serves extremely well and strong and fast.

"He's comfortable coming to the net. It's nice to see. I think he's the only guy that really comes to the net after every first and second serve. I think it's good for tennis to see that, particularly in these modern times when most of the players are playing from back of the court. He's a very athletic guy.

"It's difficult to play him definitely in these kind of conditions where balls are flying through the court and it's quicker than it was last year. So tough to break.

"But I didn't make too many unforced errors. I'm very pleased with the way I served, with the way I was holding my service games. Just the way I felt, the way I played, it was all positive."

Third seed Ruud ground out a 6-1 7-6 (9-7) victory against Frenchman Richard Gasquet, with the Norwegian saving three of four break points in what proved to be a tightly fought contest.

Mistakes from Gasquet were ultimately costly, the veteran having 10 unforced errors in the second set compared to Ruud's two.

Seventh seed Andrey Rublev was also victorious, the Russian winning 6-2 6-3 against American John Isner, while the British duo of Jack Draper and Dan Evans progressed to the last-32 stage, beating Arthur Rinderknech and Brandon Nakashima respectively.

Rafael Nadal is not treating the Paris Masters as a chance to fight for a place at the top of the ATP rankings.

Nadal has played only once – alongside the now-retired Roger Federer at the Laver Cup – since he was knocked out in the fourth round of the US Open by Frances Tiafoe.

The 36-year-old has won two grand slam titles in 2022, at the Australian Open and the French Open, seeing him sit one clear of Novak Djokovic when it comes to the record amount of major triumphs.

Yet it is Nadal's fellow Spaniard Carlos Alcaraz, some 17 years his junior, who sat top of the world rankings ahead of the Paris Masters and the season-ending ATP Finals in Turin.

Nadal could yet end the year at the summit, but to overtake Alcaraz he would likely need a deep run at the Paris Masters – one of two ATP 1000 tournaments he is yet to win in his illustrious career – and in northern Italy.

However, Nadal, who became a father last month, says he now has a much simpler aim than becoming the best player on the planet.

"To be clear, I understand it's an interesting point because you're talking about fighting for number one, [but] I don't fight any more to be world number one," Nadal said in a press conference on Tuesday, a day ahead of his opening match against Tommy Paul in the French capital.

"I just fight to keep being competitive in every event that I play. It's something I said a long time ago, I will not fight any more to be number one.

"I did in the past. I achieved that goal a couple of times in my career and I have been very, very happy and proud about achieving that. But I am at a moment in my tennis career where I don't fight to be number one.

"I'm just excited to be here. I'm here to try my best and then accept things how they are coming. Hopefully, I will be ready, I'm going to try to be competitive. Let's see. I'm excited about it."

Having dominated the game for so long, Nadal and reigning Paris Masters champion Djokovic find themselves ranked at second and seventh by the ATP respectively.

Nadal and Djokovic are the only players in the top 10 aged over 30, with four of the other eight players aged under 25.

"My feelings are that I am proud of all the things that I was able to still be here in 2022," Nadal said, when asked what it was like to be competing against the next generation of talent.

"It's something that says that I did a lot of things well in my life, not only my tennis career. To hold the passion, to hold the love for the game and fighting spirit.

"I'm proud of that and just hope that I can enjoy the last two events of the year."

With his son not yet a month old, Nadal conceded he is missing home.

"[A] different approach to usual. It has always been difficult to leave home, to be honest," he said.

"It's quite interesting how even after two or three weeks you leave your son at home and [are] not be able to go see him. It's something quite interesting how even after only three weeks of knowing him you start missing him.

"So yeah, a new experience, all changes are difficult in his life, and you need to adapt to it."

Jannik Sinner and Marin Cilic were the two most notable first-round losers at the Paris Masters, where Taylor Fritz kept his slim ATP Finals hopes alive on Monday.

World number 12 Sinner, the 11th seed in the French capital this week, suffered a straight-sets loss to Marc-Andrea Huesler, as did 15th favourite Cilic against Lorenzo Musetti.

Ninth seed Fritz downed Alejandro Davidovich Fokina 7-5 6-2, with Cameron Norrie and Frances Tiafoe also recording straight-sets victories against Miomir Kecmanovic and Lorenzo Sonego respectively.

Victory for Fritz kept the American in the hunt for qualifying for November's ATP Finals in Turin for the first time, needing to reach the final in Paris to overtake Felix Auger-Aliassime or Andrey Rublev.

"Right now I'm just focused on kind of playing myself into the tournament," said Fritz. "I feel like any time this year that I've won a couple of matches in a tournament, then I've done well.

"So I'll just try to focus on these early rounds. Turin is still in the picture, obviously, but there's not much else I really could have done.

"Felix has played really, really well, so he deserves it, but I am going to try to steal his spot this week for sure."

Home favourite Gilles Simon awaits Fritz in the second round at the ATP 1000 event after defeating Andy Murray 4-6 7-5 6-3.

Alexander Bublik and Mikael Ymer played out another three-set battle, with the former triumphing 6-1 6-7 (2-7) 6-4.

Richard Gasquet, Yoshihito Nishioka, Karen Khachanov, Maxime Cressy, Nikoloz Basilashvili and John Isner were the other first-round winners on the opening day in France.

Novak Djokovic might be a player that drives fear into the heart of his opponents, but the Serbian insists he is not the Halloween boogeyman of the tennis tour.

As he prepares for a title defence at the Paris Masters, the 21-time grand slam winner is naturally out to put the frighteners up his rivals.

But when asked on Sunday whether he was "the monster of tennis", because of his strong track record against the cream of the sport, Djokovic had to smile and laugh it off.

"The monster? I don't know the significance of that word in your language, but in mine it is not really the best," he said in a press conference.

"I prefer not to be the monster of the tennis. But yeah, the record against pretty much all the top players is positive, which is great.

"We played so many tournaments throughout the year and throughout our careers, and some of us have been there more than some of the younger players. So playing more matches helps, I think, to know how to approach every next big challenge when you play one of your top rivals.

"I have managed to do well throughout my career, which is great, which is something that I always intended to do."

Djokovic earned a 27-23 win-loss record in his favour against Roger Federer and he leads Rafael Nadal 30-29 and is 25-11 up on Andy Murray across their tour careers.

He has lost his lone meeting with new world number Carlos Alcaraz, which came on clay in the Madrid semi-finals earlier this year, and there could be more such clashes during the final years of Djokovic's career.

At the age of 35, Djokovic remains a force to be reckoned with. He gets a first-round bye in Paris and will face Maxime Cressy or Diego Schwartzman in his opening match 

The world number seven has won his last three singles tournaments, with a triumph at Wimbledon followed by titles at Tel Aviv and Astana.

Djokovic has six Paris Masters titles, the joint-most he has managed at any of the ATP 1000 events, level with his haul from Miami and the Internazionali d'Italia.

His ranking is unusually low, and that can to a large extent be attributed to him being prevented from playing in Australia and North America this season, due to his refusal to accept a COVID-19 vaccination.

Djokovic also suffered from Wimbledon being stripped of ranking points amid the Ukraine crisis, meaning that despite successfully defending his title at the All England Club, he lost the 2,000 ranking points he collected at the grand slam in the 2021 season.

He said his experience after being banished from Australia in January was "challenging".

"It was a completely new experience for me," Djokovic added. "Unfortunately not a great one but still a life experience, and a possibility for me to grow stronger out of that."

Rafael Nadal has withdrawn from the Canadian Open as the Spaniard has not fully recovered from an abdominal tear. 

Nadal's bid to complete a rare clean sweep of the grand slams ended when he suffered an injury setback at Wimbledon last month.

The 22-time major champion pulled out ahead of a semi-final against Nick Kyrgios, who received a walkover and lost to Novak Djokovic in the championship match.

Nadal was due to return in Montreal next week, but on Friday revealed he will not travel to Canada to play in a tournament he has won five times.

The world number three wrote on Twitter: "From the vacation days and my subsequent return to training, everything has gone well these weeks. Four days ago I also started training the service and yesterday after training, I had a little discomfort that was still there today.

"We have decided not to travel to Montreal and continue with the training sessions without forcing ourselves. I sincerely thank the tournament director, Eugene [Lapierre], and his entire team for the understanding and support they have always shown me and today was no exception.

"I hope to play again in Montreal, a tournament that I love and that I have won five times in front of an audience that has always welcomed me with great affection.

"I have no choice but to be prudent at this point and think about health."

Nadal's withdrawal comes just over three weeks before the US Open gets under way at Flushing Meadows.

Djokovic has also withdrawn from the Montreal event, having been ineligible to enter Canada due to being unvaccinated against the COVID-19 virus.

The men's tennis tour has scrapped plans to stage four tournaments in China later this year as the pandemic continues to take its toll on the sporting calendar.

Mandatory quarantine rules make it unfeasible for international players and tour officials to travel to the events, including the Shanghai Masters, a top-tier ATP 1000 tournament.

The lucrative Shanghai event had been due to run from October 9-16 and would have featured many of the world's top players.

Also cancelled are the Chengdu Open and the Zhuhai Championships, which were scheduled to begin on September 26, and the China Open, billed for the following week.

The ATP said it had cancelled the three-week China swing "due to ongoing restrictions related to COVID-19".

It marks a third successive year in which the run of tournaments has had to be cancelled, with China last hosting ATP events in 2019, before the pandemic hit.

At the same time as it cancelled the tournaments in China on Thursday, the ATP made provision for its players to keep earning by announcing six new events to take place in September and October.

Those events will be played in San Diego, Seoul, Tel Aviv, Florence, Gijon and Naples, the ATP said, with all at ATP 250 level, the lowest rung of the main tour.

The WTA, which runs the women's tour, announced last December it would be suspending all its tournaments in China due to concerns over the wellbeing of Peng Shuai, a professional tennis player who appeared to allege she had been sexually assaulted by a powerful former government official.

Former doubles world number one Peng has since denied making the accusations, yet the WTA has remained concerned for her safety and freedom.

Novak Djokovic became the oldest winner of the Internazionali d'Italia men's singles title in the Open Era as he fended off Stefanos Tsitsipas on the clay in Rome.

The world number one said he played a "perfect set" to race through the opener, before coming from a break down in the second to earn a 6-0 7-6 (7-5) victory in Sunday's final.

Djokovic made it a record-extending 38th Masters 1000 title in what was his 55th final at this level, and it was his sixth triumph at this event in the Italian capital.

At 34 years, 11 months and 23 days old, Djokovic is 10 days older than the previous oldest Rome champion, Rafael Nadal, who took the title last year.

He boosted his head-to-head record to 7-2 against Greek star Tsitsipas, winning their last six matches and all five they have contested on clay, including last year's French Open final where Djokovic came from two sets behind to scoop the grand slam. This victory clearly augurs well for Djokovic's upcoming title defence in Paris.

Djokovic broke serve to love in the opening game, Tsitsipas swatting a volley into the net to hand over the early advantage and set the tone for a wildly one-sided set.

Tsitsipas broke to lead 3-1 in the second set and he served for it at 5-3 but was broken to 15, sending a forehand wide on game point. The tie-break that soon followed was hard fought, with Tsitsipas looping a backhand long on match point as Serbian Djokovic earned the trophy once again.

Reflecting on his fast start, and his first title of 2022, Djokovic said on Amazon Prime: "I pleasantly surprised myself, I can say, even though I had a clear game plan and strategy coming into the match. I knew what to expect from the other side so I knew what I had to do, but I did play a perfect set, no doubt about it.

"After that it was a little bit tight, the beginning of the second for me. He used it, and at this level one or two points can turn a match around and he was back in the game. At 4-1 up for him and 30-40, the match could have easily gone into a third set, but I somehow managed to find the right shots at the right time to come back in the game, and the tie-breaker, I guess I was just an inch better, maybe calmer, and it was a tight tie-break for both of us."

Ahead of the French Open, which gets under way next Sunday, Djokovic is feeling in great shape for his title defence. Having missed the Australian Open in January in a deportation drama, Djokovic will head to Paris as a major rival to teenage sensation Carlos Alcaraz.

Should Djokovic triumph at Roland Garros, he would match Nadal's men's record of 21 grand slams.

"I've been building my form in the last couple of weeks and like the previous years I knew that my best shape on clay was usually coming around Rome time," Djokovic said.

"So it couldn't be a better time, coming into Roland Garros with a title at this wonderful tournament. I'm going to Paris with a lot of confidence."

Novak Djokovic will face Stefanos Tsitsipas in the Internazionali BNL d'Italia final after beating Casper Ruud.in straights sets to claim his 1,000th ATP Tour win.

Djokovic secured a return to the top of the rankings by defeating Felix Auger-Aliassime on Friday and the legendary Serb, who turns 35 next week, was celebrating again in Rome on Saturday after reaching an astonishing landmark.

The 20-time grand slam champion beat Ruud 6-4 6-3 at the Foro Italico to set up a repeat of last year's French Open final, which he won by storming back from two sets down to deny Tsitsipas a maiden major triumph.

Djokovic is only the fifth man in the Open Era to reach 1,000 wins and will take his record tally of ATP Masters 1000 finals to an incredible 55 on Sunday.

A five-time winner on the clay in the Italian capital, Djokovic made a blistering start, breezing into a 4-0 lead as Ruud was unable to hold twice under huge pressure from the Serb.

Ruud warmed to the task, breaking back to reduce the deficit to 5-3, but the first set was over when the 23-year-old sliced a backhand long after being forced wide by the top seed.

Norwegian Ruud started the second set with a commanding hold to love and there were no further break points until Djokovic moved into a 4-3 lead.

Ruud had saved three break points with excellent defence on the back foot, but Djokovic was not to be denied at the fourth time of asking.

Djokovic consolidated that break to stand on the brink of the final and then broke again to seal the victory with his 20th winner of the semi-final, dispatching a forehand beyond Ruud, who he beat at the same stage of this tournament two years ago.

The Belgrade native will be out to extend his record of ATP Masters 1000 titles to 36 when he faces Greek Tsitsipas for the first time since breaking his heart at Roland Garros last season.

Stefanos Tsitsipas sank the title hopes of Alexander Zverev as the Greek star edged the Rome edition of their semi-final series on clay this season.

At the Internazionali d'Italia, Tsitsipas scored a 4-6 6-3 6-3 victory over German Zverev to earn a place in Sunday's final.

These two players have now met 12 times in their careers, and Tsitsipas holds an 8-4 head-to-head winning record.

Three of those matches have come at clay-court ATP 1000 tournaments in the past four weeks, with Tsitsipas winning a semi-final on the way to the title in Monte Carlo, then losing to Zverev at the same stage in Madrid.

This latest instalment in Italy was a gripping contest, as the players battled to take on Novak Djokovic or Casper Ruud for the title.

An early break came in the seventh game when, serving at 30-40, Tsitsipas attacked the net but Zverev hit the net cord on his backhand return. The deflection disorientated Tsitsipas slightly and he volleyed wide. One break was enough for the set.

Tsitsipas broke in the second game of the second set, with Zverev serving a double fault at the critical moment, and then got decisively ahead in the fifth game of the decider when Zverev netted on the forehand.

This was a strong win for last year's French Open runner-up, who lost that championship match from two sets up against Djokovic at Roland Garros. It carries Tsitsipas through to his first Internazionali d'Italia final, and a 20th final of his ATP career. He has an 8-11 record in finals to date, and a tour-leading 31 match wins this season.
