Daniil Medvedev got his ATP Finals title defence started in impressive fashion as he came from behind to defeat Hubert Hurkacz.

In the first match of the singles draw in Turin, Medvedev overcame a difficult start to ultimately cruise to a 6-7 (5-7) 6-3 6-4 win over the Wimbledon semi-finalist.

Hurkacz showed flashes of his quality, but made 17 unforced errors to Medvedev's eight as the second seed did not offer up a single break point.

Medvedev, who did not win a match in his debut at the tournament in 2019, tops the Red Group, which also includes Alexander Zverev and Matteo Berrettini.

Hurkacz's aggressive net play saw him make the breakthrough in the first set tie-break, with neither player having offered up a single break point during the opener.

The Pole did lose three successive points to go from 6-2 up to 6-5 before eventually taking the set at the fourth time of asking.

Yet Medvedev controlled things in set two, breaking early to nose himself ahead, with Hurkacz losing the composure he had shown in the opening exchanges.

Medvedev took the set at the third opportunity, and Hurkacz's frustration followed into the decider as the Russian breezed into a 2-0 lead.

Hurkacz offered a reminder of his class with a deft volley that left Medvedev with too much to do, yet the world number nine slipped up with a similar shot in the next game to give his opponent the edge.

Despite battling back from 0-30 down to hold serve and keep himself in the match, Hurkacz did not have an answer for Medvedev's power, as the world number two served out a relatively routine win.

Roger Federer is unlikely to compete at next year's Australian Open, but the 20-time grand slam champion is not yet thinking of retirement, so says coach Ivan Ljubicic.

Federer has endured an injury-hit two seasons. After reaching the semi-finals at the 2020 Australian Open, the Swiss star underwent knee surgery, with a complication in his recovery leading him to take the rest of the year off.

That prolonged rehabilitation, plus the strict COVID-19 regulations in Australia, meant he did not compete in Melbourne earlier this year, but Federer returned to the ATP Tour in Qatar in March.

He went on to reach the last 16 of the French Open, losing to Matteo Berrettini, and the quarter-finals at Wimbledon, where he went out to Hubert Hurkacz.

However, he has not featured since then after undergoing surgery for another knee problem sustained on the grass-court circuit.

With Australia's tight coronavirus restrictions still in place, it is unclear whether Novak Djokovic, who has tied level with Federer and Rafael Nadal on 20 major wins, will compete in Melbourne early in 2022.

Nadal, too, has not yet confirmed his participation, and with Ljubicic suggesting Federer will not be fit in time, all three greats could be missing from next year's first grand slam.

"I think there are very few chances, he is still recovering and knowing him he wants to be sure he can play to win the tournament and be at 100 per cent," Ljubicic said.

"So I think Australian Open is not a real possibility right now. But he will go step by step because he is 40 years old and he needs to be patient. He cannot recover as quickly as he used to."

Despite doubts over his participation in Australia, and the time he has spent away from the court in the past two years, Federer is not considering retirement just yet.

"We have spoken and I can guarantee he wants to return playing tennis," Ljubicic added. "When he will decide to stop, he will retire, but I don't think it's going to happen all of a sudden."

Ljubicic is only two years Federer's senior and, as a player, reached a high of world number three back in 2006. He has coached Federer since 2016, helping him to three grand slam titles.

"Many times I found myself wondering what am I doing here? But in the end I hope and I think I was able to help him in those few moments he needed in the right way at the right time," Ljubicic said.

"There's always a risk when you meet your idol in person, as you may discover something you don't like, but with him, it is not the case. With him, there are no risks, he really is an extraordinary person. 

"I have been lucky enough to live beside him in the past six years and I enjoyed it very much. I really have fun with him. Is it difficult? No, it's just beautiful. When we discuss tennis, I ask myself: why he is paying me?"

Carlos Alcaraz rounded off a superb 2021 by claiming the ATP Next Gen Finals title with a straight-sets victory over Sebastian Korda.

Alcaraz produced a performance in keeping with a breakthrough year for the Spaniard, prevailing 4-3 (7-5) 4-2 4-2 in Milan.

It marked Alcaraz's 32nd tour-level win of a year that also saw him reach the quarter-finals of the US Open.

The 18-year-old is the youngest player to claim 32 wins in a year since 1992, when Andrei Medvedev achieved the feat at 18.

Alcaraz faced five break points in his first two service games but had to stave off just one more the rest of the way.

He did fall 0-30 behind when serving for the match, yet Korda could not deny Alcaraz his second Tour title of the year.

"It is amazing," Alcaraz said in his on-court interview. "To be able to win this tournament means a lot to me.

"I am so excited right now and emotional. I was very, very nervous at the start.

"I had to be calm to save the break points. I know Korda is serving very well, so I had to play my best in those moments.

"It went 0-30 on my serve. So I had to be focused in that moment and I had to stay calm. It was really, really tough."

Andy Murray believes his game will improve in the off-season after the former world number one's 2021 campaign came to an end at the Stockholm Open.

Murray stunned top seed Jannik Sinner on Wednesday, however, the three-time grand slam champion lost 6-2 3-6 6-3 to Tommy Paul in Thursday's quarter-final.

Currently ranked 143rd on the ATP Tour, Murray had warned the days of him progressing deep in tournaments again were on the horizon following his upset of Sinner midweek.

Murray's career has been ravaged by injuries – the 34-year-old underwent hip resurfacing in 2019, but the veteran feels he is on the right track.

"My game will improve, I think, over the off season - I'm pretty clear on the things that I need to work on," said Murray, with his focus now turning to the 2022 Australian Open.

"I need to make sure we get a good plan in place that come the beginning of January those improvements have been made."

Paul needed two hours, 16 minutes to see off Murray at the ATP 250 tournament in Stockholm.

"It was a lot of fun," said American Paul. "He is a legend. I played some of my best tennis today and I even looked over at my coach mid-match and thought it was fun to battle him today.

"It was the game plan to keep him running after his long match [against Jannik Sinner] yesterday. I tried to keep him running. I played tight and stuck to my game plan in the third set."

Daniil Medvedev has confirmed he will play at the Australian Open next year, as the debate over vaccine mandates continues.

Medvedev was defeated by Novak Djokovic in the final of this year's tournament, though the Russian has gone on to enjoy a brilliant season.

He has won four titles, including his first grand slam, beating Djokovic at the US Open in September to end the latter's pursuit of a clean sweep of the four majors in 2021.

Djokovic and Medvedev met again on Sunday, with the world number one coming out on top to clinch his sixth Paris Masters title and a record 37th triumph at ATP 1000 events.

Medvedev had appeared non-committal about being vaccinated against COVID-19, which is likely to be a requirement for any player wishing to compete at the Australian Open, but he dispelled doubts around his involvement when he tweeted on Tuesday: "See you in January @AustralianOpen."

While Medvedev will be involved in Melbourne, the participation of Djokovic – who is a nine-time Australian Open champion – is not yet known.

The Serbian has previously appeared hesitant over the coronavirus vaccine mandate, though he has not revealed whether he has been vaccinated or not.

Australia has enforced strict measures throughout the pandemic, with Melbourne having been under lockdown on six occasions since March 2020. Indeed, the city only lifted its most recent restrictions towards the end of October.

Athletes arriving in Australia prior to last year's event had to go through a mandatory two-week hotel quarantine.

Despite Australia's vaccination programme gaining momentum, travellers who are not citizens must be able to provide proof of vaccination and a negative PCR test result, while quarantine regulations vary depending on state rules.

Tennis Australia is reportedly still hopeful of securing a deal for unvaccinated players to compete in the tournament, subject to a two-week quarantine, with prime minister Scott Morrison suggesting players could be granted an exemption. 

On Tuesday, though, Victorian premier Daniel Andrews insisted players will have to be vaccinated.

"I'm not going to have people sitting in the grandstands having done the right thing, only to have millionaire players that ought [to] be vaccinated running around the place being essentially at such higher risk of spreading this – getting it and giving it," he said.

Speaking last month, Djokovic said: "I don't know if I'm going to Australia, I don't know what's going on. Currently, the situation is not good at all.

"Of course, I want to go, Australia is my most successful grand slam, I want to participate, I love this sport, I still have motivation."

Novak Djokovic claimed his sixth Paris Masters title on Sunday, overcoming Daniil Medvedev and gaining revenge for his defeat in the US Open final in the process.

Prior to this week's Masters 1000 event, Djokovic had not played since going down 6-4 6-4 6-4 to world number two Medvedev at Flushing Meadows in September.

That defeat ended Djokovic's hopes of sealing a calendar Grand Slam, but he was in fine form this week as he regained the title he last won in 2019, having not played in the competition last year.

Defending champion Medvedev started the final brilliantly, but Djokovic rallied to win 4-6 6-3 6-3, claiming a record-setting 37th Masters title in the process.

And the world number one explained how he learned from the mistakes he made in New York to prevail this time around, taking his head-to-head record with Medvedev to 6-4 in the process.

"I went back and reviewed the final of the US Open to see what I did wrong and what I did right," Djokovic told the Tennis Channel.

"I tried to read the patterns of his serve and the ball toss, maybe. I tried to look for the small details, because it was a match of small margins."

Reflecting on the showdown in Paris, Djokovic added: "He started better, broke my serve in the first game and I came back. He served the first set out pretty comfortably, but I felt as if I was there.

"I thought it was only a matter of time when I was going to read his serve better and start to make some plays.

"You can't go through him. You have to find a way to play with controlled aggression, play the right shots at the right time and make him come in. It's variety that wins matches against him. We both suffered on the court and there was a lot of gruelling rallies."

Djokovic, who had already secured a record seventh year-end number one, has won 49 matches in 2021, losing on just six occasions.

Novak Djokovic came from a set down to defeat Daniil Medvedev 4-6 6-3 6-3 and win the Paris Masters on Sunday.

Djokovic lost to Medvedev in the US Open final in September, with that defeat ending his hopes of a calendar Grand Slam.

But the Serbian, whose semi-final win over Hubert Hurkacz ensured he will be the year-end world number one for a record seventh time, got his revenge in France.

It marks a fifth title of the year and a sixth triumph at this event for Djokovic, who did not compete in the tournament last year – Medvedev winning it in his place.

The 34-year-old had it far from his own way, with Medvedev instantly going a break up, and although Djokovic hit back to draw level at 2-2, the world number two held off a second break point before nosing himself ahead at 4-3.

Yet having served out the first set at the first time of asking, the US Open champion slipped up in the fourth game of the second as Djokovic reeled off some superb returns, and he did not look back.

With the momentum and crowd on his side, Djokovic broke Medvedev twice in quick succession in the decider, and although he was denied claiming the win on his serve, it merely delayed the inevitable.

Medvedev's powerful serve was not enough, with Djokovic keeping his composure to seal a record-setting 37th Masters 1000 title with a sublime forehand into the corner of the court following a draining rally.

Novak Djokovic will wait until he is retired to assess his stunning feats but recognises rankings records as "the paramount achievement of our sport".

The Serbian will finish the year as the world number one for a seventh time, a new record having previously been tied with Pete Sampras on six.

Djokovic, who also leads the way with 345 weeks at the top all-time, secured his position by advancing to the Paris Masters final with a last-four win over Hubert Hurkacz on Saturday.

"Every achievement is special," said the 20-time major champion. "I try to make myself aware of the fact that I am in a very unique position.

"It's difficult for me to understand the magnitude of these achievements, not just for myself but for the sport while I'm still [an] active player.

"Probably when I retire, I'll be able to reflect on that a little bit more and appreciate it a little bit more.

"Of course I'm very appreciative and grateful for it now, but what is the next challenge is always in your mind while you're an active player. It's constantly another task, another tournament.

"So [I] don't have really much time to enjoy the success, so to say, because you always have to turn the next page."

However, he added: "Being historically [the] number one-ranked player in the world is probably the paramount achievement of our sport.

"Also, finishing the season as year-end number one requires full commitment throughout the entire year and consistency and playing the best tennis in the biggest events, which accumulate the most points that enable you to be highly ranked. So that's what I have done this year."

Djokovic will have his work cut out as he pursues a 37th Masters 1000 title, now facing Daniil Medvedev, the man who denied him the calendar Grand Slam in the US Open final.

"The job is not done," added Djokovic. "Obviously reaching the finals of one of the biggest tournaments that we have in our sport on our tour is something that stands out regardless of the year-end achievement that is completed.

"So hopefully going to have another great match and then take it from there.

"For now I am just proud and extremely happy. Obviously that was one of the biggest goals and it's always one of the biggest goals, to try to be number one and end the season as number one.

"To do it for the record seventh time and surpass my childhood idol and role model, Pete, is incredible. Very grateful, very blessed to be in this position.

“I wasn't bored without tennis, but I like competing so I was looking forward to coming to Paris and the biggest reason coming here was to clinch the year-end number one.

"Now that I managed to do it, it's a huge relief, as well."

Teenage sensation Carlos Alcaraz put in an impressive display to upstage eighth seed Jannik Sinner in straights sets in the third round of the ATP Paris Masters on Wednesday.

Alcaraz was on top for most of his 7-6 (7-1) 7-5 victory, winning 80 per cent of his first-serve points and 75 per cent of net points against Sinner.

Sinner showed determination to stay in both sets, with the Italian saving nine of the 11 break points he faced, but it was ultimately in vain.

The European Open winner will be among those sweating as the race to qualify for the ATP Finals in Turin heats up.

After the win, 18-year-old Alcaraz said: "I'm so happy for this win as Jannik was fighting for a spot at the ATP Finals. It's my third Top 10 win of the year.

"I think Jannik and I will have a great rivalry in the future... I think that I played really, really aggressive, more than him. I think that was one of the keys."

Alcaraz will now face qualifier Hugo Gaston in the next round after the Frenchman impressively knocked out 12th seed Pablo Carreno Busta 6-7 (3-7) 6-4 7-5.

Interesting day for Turin hopefuls

It was a mixed day for others looking to secure a spot at the season-ending ATP Finals later this month as Felix Auger-Aliassime – ranked 12th in the ATP Race to Turin – lost in straight sets to Dominik Koepfer, who added to his impressive list of victims after beating three-time grand slam champion Andy Murray in the first round.

Koepfer will play another Turin hopeful, the 10th-ranked Hubert Hurkacz after he beat Tommy Paul in straight sets.

Cameron Norrie also impressed in his 6-3 6-4 win over Reilly Opelka, which was his 50th tour-level win of the year.

Taylor Fritz awaits after the American stunned fifth seed Andrey Rublev 7-5 7-6 (7-2).

Medvedev and Zverev ease through but Tsitsipas out

Second seed and US Open champion Daniil Medvedev had a routine first match of the tournament as he swept past Ilya Ivashka 7-5 6-4, while Olympic Games gold medallist and fourth seed Alexander Zverev also had few problems against Dusan Lajovic 6-3 7-6 (7-5).

However, third seed Stefanos Tsitsipas exited after retiring hurt with an apparent arm injury against Alexei Popyrin in the first set with the score at 4-2 to the Australian.

Popyrin will now face fellow countryman James Duckworth, who followed up his impressive win against 14th seed Roberto Bautista Agut with a 6-3 3-6 6-3 victory against Lorenzo Musetti.

Elsewhere, 11th seed Diego Schwartzman was shocked by qualifier Marcos Giron 7-6 (7-2) 7-6 (7-4).

There were also wins for 16th seed Grigor Dimitrov against Karen Kachanov, and Sebastian Korda over Marin Cilic.

Gael Monfils will go up against world number one Novak Djokovic in the third round after the experienced French 15th seed came from behind to beat compatriot Adrian Mannarino 2-6 7-6 (7-4) 6-2.

Novak Djokovic recovered from a second-set blip to emerge victorious 6-2 4-6 6-3 in his first match since the US Open at the Paris Masters.

Victory in Paris would see Djokovic – competing for the first time since September's loss to Daniil Medvedev in the Flushing Meadows final – clinch the year-end number one ranking for a record seventh time.

Djokovic looked to be on course for a routine victory to start his campaign after comfortably taking the first set against Marton Fucsovics in their second-round contest on Tuesday.

However, the top seed's Hungarian opponent fought back to force a decider, hitting 13 winners to seven unforced errors in the second set.

But Djokovic – a record five-time Paris Masters champion – ensured a remarkable turnaround was not forthcoming, breaking Fucsovics twice in the third and, after letting one match point slip, clinching his second to secure victory.

Felix fights back

Ranked 12th in the ATP Race to Turin, Felix Auger-Aliassime needs to lift the trophy in Paris and hope Casper Ruud and Jannik Sinner do not reach the latter stages to make it to the ATP Finals.

Auger-Aliassime risked falling at the first hurdle on Tuesday as the ninth seed was forced to fight back to defeat Gianluca Mager 4-6 6-4 6-1.

"I had difficulty with my pace at the beginning of the match," said Auger-Aliassime. "I didn't hit enough first serves so I had a bit of pressure on my second serve.

"So I could have served better in the first set. I [had] a poor game at four-all and I got broken, but even before that there were moments at 30-all it was a bit hot and a bit tight. I think I relaxed. I found a better pace at the beginning of the second set, and it went even better as the match went forward."

He will next face Dominik Koepfer in the second round following the German's stunning win over Andy Murray on Monday.

Alcaraz sets up Sinner clash

Sinner will have an extremely testing second-round clash after Carlos Alcaraz came from behind to see off wild card Pierre Hugues-Herbert.

Alcaraz let slip a 4-2 lead in the first set to lose that on a tie-break but won six straight points in a second-set breaker before eventually battling to a 6-7 (4-7) 7-6 (7-2) 7-5 win in two hours, 53 minutes.

"It's not easy to play against a home player," Alcaraz said. "I think we played a good level and it was a great match, so I am happy to win. He has a great serve, so I had to return better and remain focus. I think that was the key. I am playing at a good level and I want to finish the year strong."

Diego Schwartzman – the 11th seed – needed three sets to see off John Millman, 15th seed Gael Monfils reversed a one-set deficit against Miomir Kecmanovic and 16th seed Grigor Dimitrov survived a three-setter with Richard Gasquet.

But one seed did fall on Tuesday, Roberto Bautista Agut (14) edged by James Duckworth in three sets.

Dominic Thiem has confirmed he has been given a coronavirus vaccine and will return to action in Abu Dhabi next month with the objective of playing in the 2022 Australian Open.

The 2020 US Open champion has been out of action since suffering a wrist injury at the Mallorca Championships in June.

Thiem on Tuesday revealed he has made good progress with his recovery and will play in the World Tennis Championship, an exhibition event that will be staged from December 16-18.

The 28-year-old had stated he wanted to wait for a Novavax jab, but was urged by Austrian minister for Social Affairs, Health, Care and Consumer Protection Wolfgang Muckstein to take an alternative vaccine as his preferred choice would not be available until next year.

Thiem says he has now been vaccinated and is relishing getting back on court as he eyes a grand slam return in Melbourne in January.

"I am very happy to announce that my recovery is going well. The MRI I did today showed that my wrist injury has improved significantly," Thiem tweeted on Tuesday.

"A couple of weeks ago I started playing with soft balls and was able to switch to normal tennis balls during yesterday's practice session. My team and I strongly believe that I'll be ready to make my comeback later this year.

"I'll be returning to competition in December and will be playing the MWTC 2021 in Abu Dhabi – with the objective to return to the Tour for the 2022 Australian Open.

"Needless to say that the vaccine is needed to play both events, and in my case I have already been vaccinated. I saw recently some news about this and I had to make it very clear that I would get vaccinated. Hopefully the next time things won't be taken this far [sic] as I saw last week..."

Rafael Nadal is also set to return from injury in Abu Dhabi.

Andy Murray was defeated in the first round of the Paris Masters on Monday following a three-set battle with Dominik Koepfer.

Murray, given a wildcard entry, was initially drawn against Jenson Brooksby but the American withdrew just a couple of hours before the match was due to start because of an abdominal injury.

The three-time major singles champion instead faced German Koepfer, who triumphed 6-4 5-7 7-6 (11-9) in a contest lasting just over three hours.

Lucky loser Koepfer, in his debut in the main draw, served for the match at 5-3 in the second set but was broken to love as the contest turned topsy-turvy.

Murray had seven match points in the decider, including five in the tie-breaker, but the 2016 champion could not convert and left the court looking disconsolate.

"I was about to go back to the hotel and then one of the ATP Tour Managers texted me, 'Dom, you in? You're playing against Andy Murray'," Koepfer said. "Honestly, I was a little nervous.

"I didn't expect to play today, I was hoping that someone was going to pull out tomorrow. But a night match here in Paris, a lot of fans, they had an unbelievable crowd, the first time for me for a while. It's been a great day. Unexpected, but it worked out and I'm happy."

There was more disappointment for the United Kingdom as Dan Evans saw a strong start yield nothing as he lost in three sets to Alexander Bublik, who goes on to face sixth seed Casper Ruud.

Djokovic set for Fucsovics test

World number one Novak Djokovic will begin his campaign against Marton Fucsovics, who outlasted Fabio Fognini in a match lasing nearly two hours and 45 minutes.

Fucsovics dominated the first set but was engaged in a far tougher battle for the rest of the contest before winning 6-1 6-7 (6-8) 7-6 (7-5).

The Hungarian is 0-3 against Djokovic in his career, last losing to the 20-time major winner at the quarter-final stage of Wimbledon. The winner of this latest contest could face a last-16 meeting with Adrian Mannarino, who won in straight sets against Nikoloz Basilashvili.

Ilya Ivashka overcame Albert Ramos-Vinolas to secure a meeting with second seed Daniil Medvedev, while Dusan Lajovic will face Alexander Zverev after defeating Mackenzie McDonald.

Norrie brings up Tour century to keep Finals in sight

Tenth seed Cameron Norrie kept his chances alive of qualifying for the ATP Finals after a commanding 6-2 6-1 defeat of Federico Delbonis.

The Briton's victory, his 100th on the Tour, could help him to close the gap in the race for the year-ending tournament in Turin. Norrie started the week in 11th place, 140 points adrift of Jannik Sinner in the eighth and final automatic qualifying spot.

"It's obviously a great milestone and it shows I have been on the Tour and have a little bit of experience now," said Norrie. "It's a nice bonus, but there is a lot of tennis in the year to be played. It's a great achievement."

One man who will not qualify for the Finals is Aslan Karatsev. Last month's champion in Moscow lost in three sets to American Sebastian Korda, meaning he cannot now catch the top eight.

Rafael Nadal intends to make his Tour comeback next month and plans to play at the 2022 Australian Open.

The 20-time major champion has not played since a defeat to Lloyd Harris at the Citi Open in August.

The 35-year-old, who withdrew from Wimbledon and the Tokyo Olympics after losing to Novak Djokovic in the French Open semi-finals, also pulled out of the US Open due to a recurring foot injury.

Nadal has spent time training in Mallorca this month following treatment in Barcelona and said he was not sure when he would make his return to action.

Speaking at a sponsor event in Paris, Nadal said he hopes to play at the World Tennis Championship next month before a possible tilt at the first grand slam of next year, an event he has won just once back in 2009.

"My plan is to play Abu Dhabi in December and then in a tournament before Australia and then the Australian Open. That's my goal," Nadal said. "We're working hard to make it happen.

"The injury in my foot still needs to get a little better, but I'm already training almost an hour and a half a day so that's positive. Some days are better than others, but I'm starting to have a lot more positive days than negative ones.

"So, I'm on the right track. I'm training, I'm feeling better. I'm back on the court."

World number eight Casper Ruud and world number 13 Denis Shapovalov are two of the big names from the ATP Tour to have confirmed they will play in Abu Dhabi in the event that runs from December 16-18.

Women's Olympic gold medallist Belinda Bencic and surprise US Open champion Emma Raducanu have also signed up to make their tournament debuts.

The Australian Open, won this year by Novak Djokovic, is due to start on January 17.

Novak Djokovic is unwilling to commit to January's Australian Open as the defending champion awaits confirmation on travel and entry requirements amid Victoria's vaccine mandate.

The state of Victoria, where the year's opening grand slam takes place at Melbourne Park, has introduced a vaccine mandate for professional athletes and across most industries due to the coronavirus pandemic.

The 2021 Australian Open went ahead, albeit in February instead of January, and without fans for most of the tournament following a snap lockdown of Melbourne due to COVID-19.

Last week, Australia prime minister Scott Morrison said unvaccinated players would be allowed to contest the slam if they completed two weeks in quarantine, though Victoria premier Dan Andrews dismissed those comments, insisting athletes would not be granted access unless they received the COVID-19 vaccine.

A record nine-time Australian Open champion, world number one Djokovic remains non-committal over his looming title defence.

"Well, I'm going to decide on whether I go to Australia or not after I see the official statement from Tennis Australia," Djokovic said as he prepares for the Paris Masters – his first tournament since losing to Daniil Medvedev in September's US Open final.

"Right now, we don't have any official announcement or statement. So until that's out, I won't be talking about this anymore, because I don't want to be part of the stories about the assumptions and what-ifs.

"When official condition requirements to travel to Australia and play in Australia are out, then obviously I'll see what I personally do with that, and also the bigger group of the players, you know, because the situation is obviously different in Australia than most parts of the world."

World number two Medvedev also refused to confirm his Australian Open participation.

"I always said it, that I really like Novak's answer about this. I want to keep my medical, no matter if it's about vaccine, leg injury, head injury... I want to keep my medical private for a reason," Medvedev said.

"I feel like tennis is such a brutal sport where you're always one on one against your opponent, and any information you give him can go against you.

"If you're playing Australia, it's obvious you're vaccinated. So that's why I said I'm willing to play Australia, but I won't say if you'll see me there, but we're going to see in January."

World number one Novak Djokovic said he will return to action at the Paris Masters blessed to be a more "humble" tennis player.

The Serbian makes his first appearance since his US Open final defeat to Daniil Medvedev at the ATP 1000 tournament in the French capital.

That defeat in New York cost Djokovic the chance to become only the third man to win a singles calendar slam by winning all four majors in the same year.

Djokovic also missed the opportunity to move top of the all-time Grand Slam tournament winners list and remains joint-top alongside Roger Federer and Rafael Nadal with 20 titles.

However, the 34-year-old – whose status for the 2021 Australian Open remains unknown – was phlegmatic when he reflected on his loss to Russian world number two Medvedev.

"In a most ideal scenario, I would have won all four of them," Djokovic told a media conference. "Knowing I was so close gives me great encouragement for the future, but it also makes me feel humble about my game, about my career.

"It gives me a kind of reality check where I have to go back to the practice court and really understand what needs to be done so that I could improve.

"This was not an ordinary loss considering the circumstances. I have learned over the years to deal with losses in such way that I treat them as great opportunities for growth.

"I feel that the US Open loss in the final has arrived arguably at the worst or at the best time for me, in a way.

"I'm disappointed that I lost the match, but I feel like I was blessed to experience love from the crowd and support from the stadium that I have never experienced before in my life in New York, and actually not in many places around the world.

"That kind of energy that I received from the crowd from the moment I stepped on the court until I stepped out is a win for life."

Djokovic, who has won four of the last eight Paris Masters tournaments, claimed the prospect of ending the year as the world number one ahead of Medvedev will motivate him.

Should he do so then Djokovic would leapfrog Pete Sampras for the most year-end number one finishes in history with seven.

He will face either Italian Fabio Fognini or Hungarian Marton Fucsovics having received a bye through the first round.

"The year-end number one is on the line between Medvedev and myself, and I'm in a pretty good position," added Djokovic, who has won 85 ATP tour titles.

"That's obviously the goal for the end of the season other than trying to do well in the Davis Cup with the national team. So hopefully I can have a strong finish of the season and clinch that year-end number one.

"I’m pleased to be back. I have been training really well the past couple of weeks. And I have had plenty of success in Paris over the years, so that gives me enough reason to believe that I can do well.

"The lack of match play could be dangerous, so I have to really make sure that I start off my first match very well with a good intensity and build my form."
