The Grand Slam Board has announced that first-to-10 tie-breaks will conclude the final sets of all four majors with immediate effect.

Starting with May's French Open, the decision is being adopted on a trial basis with the aim of providing "greater consistency" to the rules when matches go the distance.

Prior to Wednesday's announcement, the French Open, Australian Open, US Open and Wimbledon each had their own rules when games went to a deciding tie-break.

The Australian Open is the only grand slam to already employ the first-to-10 rule at 6-6.

Wimbledon previously played first-to-seven at 12-12, while the US Open played a first-to-seven at 6-6.

There has not previously been a deciding tie-break at Roland-Garros, with all matches continuing until a player secured a two-game lead in the decider.

A statement released on behalf of Grand Slam Board members Jayne Hrdlicka, Gilles Moretton, Ian Hewitt and Mike McNulty confirmed the changes.

It read: "The Grand Slam Board's decision is based on a strong desire to create greater consistency in the rules of the game at the Grand Slams, and thus enhance the experience for the players and fans alike.

"This trial, which has been approved by the rules of the tennis committee governed by the ITF, will apply to all Grand Slams across qualifying, men's singles and doubles, women's singles and doubles, wheelchair and junior events in singles, and will commence at the 2022 edition of Roland-Garros."

The rule change will be reviewed after a full Grand Slam year and will remain in place should it be deemed a success.

The tweaks to the current format will ensure no repeat of John Isner's marathon battle with Nicolas Mahut at Wimbledon in 2010, which the American edged 70-68 in the final set of their first-round match.

The ATP, WTA, International Tennis Federation (ITF) and the four grand slam organisers have announced the Tennis Plays for Peace campaign.

Along with the campaign, which will include efforts on social media and at tournaments, each of the seven organisations has pledged to donate $100,000 to humanitarian relief efforts in Ukraine.

Russia invaded the country on February 24 and the conflict is still ongoing. Well over one million refugees are estimated to have fled to neighbouring countries in Europe.

A joint statement from tennis' governing bodies on Tuesday explained that the campaign is not just about donations.

"The seven bodies will also signal support via their social and digital platforms by prominently featuring the Ukraine ribbon icon, with everyone in the tennis ecosystem encouraged to use the hashtag #TennisPlaysforPeace," it read.

"In addition, physical ribbons will be distributed for ATP and WTA players to wear at the upcoming BNP Paribas Open tournament in Indian Wells."

Last week, the ITF banned Russian and Belarusian teams from competing at the Davis Cup or the Billie Jean King Cup. Russia are the holders of each title.

The ATP and WTA, meanwhile, allowed Russian and Belarusian athletes to carry on competing, but only under neutral banners.

That includes ATP world number one Daniil Medvedev and WTA world number three Aryna Sabalenka.

Roger Federer says he hopes to return to action by the end of the summer, with his recovery from knee surgery likely to rule the 20-time grand slam winner out of Wimbledon.

The 40-year-old underwent surgery on his right knee for the third time last August, and has missed five of the last seven grand slams.

Federer made the quarter-finals at Wimbledon last year, but coach Severin Luthi recently said that he "can't imagine" the eight-time Wimbledon winner featuring in London this summer.

Federer has now provided an update on his recovery to Swiss broadcaster SRF, saying that the end of summer or start of autumn is a realistic target for his return, which could mean he is back for the US Open that starts on August 29.

However, he feels "positive" about his return to the court whenever that comes.

"It will certainly be a while," Federer said. "The end of the summer, early autumn, [that's] where I'm aiming for a comeback.

"It's [the knee] fine. Much better. Obviously, I was on crutches for two months, so you have to start from the bottom.

"It [the surgery] was certainly the right thing to do, the knee wasn't right after Wimbledon [last year], so it couldn't go on.

"Currently I'm in three parts. First, the whole rehab, getting back on your feet at the beginning. Then afterwards, learning to walk and building up the whole thing.

"It's only now where I'm at the phase where I can start thinking about my comeback. I had a very good MRI a few weeks ago, which makes me feel very positive."

Federer's tally of 20 career Grand Slam titles was surpassed by Rafael Nadal in January's Australian Open, and the duo are set, fitness permitting, to team up to represent Europe in the Laver Cup, which takes place in September.

The timeline for Federer's recovery also means that he will miss the second slam of 2022, May's French Open at Rolland Garros.

Rafael Nadal would "welcome" seeing Novak Djokovic play at future grand slam tournaments if he is granted permission to do so unvaccinated against COVID-19.

World number one Djokovic has courted controversy for his views on being jabbed and was last month deported from Australia on the eve of the Australian Open.

Djokovic has confirmed he is willing to miss future slams after stating he was prioritising his right to choose what to put into his body above his sporting ambitions.

In Djokovic's absence, Nadal became Australian Open champion and now has 21 titles – the most for a male player.

Nadal believes that any further omissions from Djokovic would only be harmful to the Serbian's chances of history not the slams themselves, but he would have no issue with his rival playing in the sport's biggest tournaments.

Speaking ahead of his return to the ATP Tour in Acapulco, Nadal said: "It will affect Novak's [grand slam] history if he can't play.

"It will affect him, not the grand slams themselves. Whoever wins the most slams – it will be what it will be. Everyone takes their own decisions and must live with them.

"In that sense, hopefully the pandemic subsides and we stop having so many deaths around the world and this horror ends, and we can return to normality – not for Novak but for the world in general.

"There are many people that have suffered, but if Novak can play the grand slams unvaccinated, then he is welcome."

Nadal defeated Daniil Medvedev in an epic Melbourne showpiece to become the first man to 21 slams, but he says the achievement has not changed his life.

"Absolutely nothing has changed having 21 slams, I won't lie to you," he added.

"From 20 to 21 there is not a very large difference. Life goes on exactly the same. The only thing that has changed is that now I play tennis, which a few months ago I couldn't.

"I am very happy for everything that happened in Australia, it was very unexpected, especially before the tournament started. In my life, nothing has changed. No title is going to change what is important in my life, which are other things.

"Already, at 35 years old, I have a lot of experiences behind me, of successes and bad moments and these sensations already help me to live in a more calm and different way."

Novak Djokovic has said missing grand slams including the French Open and Wimbledon will be "the price I am willing to pay" for resisting the COVID-19 vaccine.

Last month, the world number one and 20-time grand slam winner was deported from Australia on the eve of the Australian Open after his entry visa to the country was cancelled.

That stemmed from Djokovic refusing to join the overwhelming majority of fellow tennis stars in being vaccinated against coronavirus, and amid controversy over how he handled getting the virus himself in December.

In a new interview with the BBC, Djokovic said he was prioritising his right to choose what to put into his body above his sporting ambitions.

The 34-year-old Serbian declared his stance is likely to keep him sidelined for "most of the tournaments" at present.

Djokovic is set to make his return to the court at the Dubai Duty Free Tennis Championships later this month, with vaccination not a requirement. He has been included on the entry list for next month's Indian Wells Open, but that is a tournament he may have to sit out.

He confirmed in the BBC interview that he has still yet to be vaccinated, though did not entirely rule out the prospect in the future.

"I have not," he said. "I understand and support fully the freedom to choose whether you want to get vaccinated or not."

Prior to entering Australia, where he was obliged to confirm his status, it was only widely assumed that Djokovic had not been inoculated.

Now he is keen to "speak up ... and justify certain things", adding: "So I was never against vaccination. I understand that globally everyone is trying to put a big effort into handling this virus and seeing hopefully an end soon to this virus.

"And vaccinations are probably the biggest effort that was made on behalf of the planet. I fully respect that, but I've always represented and always supported the freedom to choose what you put into your body. For me that is essential. It's really the principle of understanding what is right and what is wrong for you.

"And me, as an elite professional athlete, I've always carefully reviewed and assessed everything that comes in, from the supplements, food, the water that I drink or sports drinks. Anything really that comes into my body as a fuel.

"Based on all the information that I got, I decided not to take the vaccine as of today. I keep my mind open because we are all trying to find collectively a best possible solution to end COVID. Nobody really wants to be in this kind of situation that we've been in collectively for two years."

Djokovic is the reigning French Open and Wimbledon champion and, after Rafael Nadal's Australian Open triumph, he has been bumped down to joint second on the all-time men's grand slam list. Missing majors at this stage of his career could be a crushing blow to Djokovic's hopes of finishing top of that pile.

"I'm part of a very global sport that is played every single week in a different location, so I understand the consequences of my decision, and one of the consequences of my decision was not going to Australia, and I was prepared not to go," Djokovic said.

"I understand that not being vaccinated today I am unable to travel to most of the tournaments at the moment. That is the price I am willing to pay."

He looked to disassociate himself from the anti-vax community by saying he had "never said I am part of that movement" and declaring that was a "wrong conclusion" to draw.

At the same time, Djokovic concurred when asked if he was willing to sacrifice the chance to be seen as the greatest player of all time, and to travel to Roland Garros and the All England Club this year.

"Because the principles of decision-making on my body are more important than any title or anything else. I'm trying to be in tune with my body as much as I possibly can," Djokovic said.

"I say that everyone has a right to choose to act or say whatever they feel is appropriate for them."

Andy Murray has decided to skip the entire clay court season, including the French Open, as he feels the surface aggravated "issues" in the past.

Former world number one Murray has endured a torrid time with injuries in the past few years, but he has featured more regularly since the second half of last season.

While he only made it as far as the second round at last month's Australian Open, his preparation for the year's opening grand slam saw him reach a first final on the ATP Tour since October 2019.

He lost to Aslan Karatsev in the decider of the Sydney Classic, going down 6-3 6-3, but the Scot's run to the final provided evidence he still has plenty to offer.

Murray will not be playing in the next grand slam, though.

The eyes of the tennis world will be on Roland Garros in late May and early June, but Murray is opting to miss that and every other event on clay for fear of worsening his condition, with Wimbledon scheduled to begin on June 27.

"Right now, I am not planning on playing through the clay," the three-time grand slam winner said.

"The past couple of years, the clay has made issues worse; last year I had some issues at the beginning of the year, the clay didn't help, so I've spoken to my team about that and this year while I feel good and healthy, I don't want to take that risk.

"It's not that I wouldn't potentially play on clay in the future. Last year I almost missed Wimbledon, was close to not playing the grass season. I'm not planning on playing the clay. I will still try to compete a bit during that period, I won't do nothing, that's my plan just now.

"I had a busy end of last year and the next couple of months I won't take any risks and hopefully get a good build up to the grass season."

Murray parted ways with long-term coach Jamie Delgado in December and then decided against making Jan de Witt a permanent member of his team following a trial period leading up to and through the Australian Open.

The 34-year-old is now once again working with Dani Vallverdu, Stan Wawrinka's coach, having teamed up with him between 2010 and 2014.

But Murray accepts the situation is far from ideal, with Vallverdu only available while Wawrinka continues his rehabilitation from a foot injury that has kept him out since March last year.

"It's not been easy to find someone," Murray added.

"Obviously, Stan Wawrinka has been rehabbing for quite a long time and is hopefully coming back to the tour, but he agreed for Dani to come and work with me for a few weeks over the next month or so, which is great for me in the short term, but still trying to find a longer-term solution.

"It's not that straightforward, I'm not as in demand as a few years ago. Ultimately, I want it to be the right person. I'm aware there's no perfect setup, but medium, longer term I want some stability and will try and get that in the next few weeks."

Novak Djokovic could miss out on defending another of his Grand Slam titles, with France passing new vaccination laws that may threaten his ability to compete at Roland Garros later this year.

The 34-year-old will not defend his Australian Open title, with a drawn-out saga concerning his vaccination status culminating in his visa being cancelled for a second time after an intervention from Australian immigration minister Alex Hawke.

But the controversy surrounding the 20-time Grand Slam winner could be set to continue, with French parliament passing stringent vaccination laws ahead of May's French Open.

After French lawmakers comfortably passed the new measures, proof of vaccination status will soon be required to enter a wide variety of public places, including sports stadiums, and the country's sports ministry says there will be no exemptions for professional athletes. 

"The rule is simple. The vaccine pass will be imposed, as soon as the law is promulgated, in establishments that were already subject to the health pass," the ministry said.

"This will apply to everyone who is a spectator or a professional sportsperson, and until further notice.

"Now, as far as Roland Garros is concerned, it is in May. The situation may change between now and then, and we hope that it will be more favourable. 

"So, we'll see, but clearly, there's no exemption."

Djokovic, who is tied with Rafael Nadal and Roger Federer for all-time Slam wins in the men's game, has come in for widespread criticism regarding his failure to be vaccinated against COVID-19, as well as for appearing in public in the days after testing positive for the virus last month.

Meanwhile, Djokovic has arrived back in his native Serbia, travelling via Dubai from Melbourne to Belgrade after losing a last-ditch court appeal to remain in the country.

Spanish tennis great Manolo Santana, a four-time grand slam winner, has died at the age of 83.

Santana won the US Open, Wimbledon and the French Open twice during the 1960s, during which time he spent a period as world number one.

He also won the men's singles tennis tournament at the 1968 Olympics, though it was not recognised as a medal event at the time, while also winning the French Open men's doubles in 1963 and the Davis Cup with Spain on three occasions.

Santana retired in 1977 and in more recent times was regularly seen watching countryman Nadal – the only Spaniard to have won more grand slam titles – from the stands.

Nadal led the tributes to Santana on Saturday with an emotional post on social media.

"I have just received the terrible news of the death of our great Manolo Santana," he wrote on his official Instagram account.

"As I have said many times in the past: thank you very much for what you did for our country and for leading the way for so many. 

"You have always been a reference, a friend and a person close to everyone.

"We will miss you Manolo; you will always be unique and special. Greetings to your family and a lot of strength at this time. We will never forget you."

Amelie Mauresmo has become the first woman to be appointed tournament director at the French Open, promising to show "fierce ambition" in the role.

Former Wimbledon and Australian Open champion Mauresmo succeeds fellow former tour professional Guy Forget in the top job at Roland Garros.

Mauresmo enjoyed 39 weeks at number one in the world at the height of her career but struggled to stamp a mark at her home grand slam. She captured the junior title in 1996 but appearances in the 2003 and 2004 quarter-finals were her best performances as a professional.

The 42-year-old aspires to make a greater impact on the Paris tournament during her time in charge, having been appointed to serve until 2024.

She steps into the role after spending several years working successfully as a coach, having helped players including Marion Bartoli, Andy Murray and Lucas Pouille. She and Pouille parted company in October of last year.

Mauresmo said she was "very proud" and explained: "This tournament created a vocation within me. I started dreaming about tennis thanks to Roland Garros! At age four, I sat in front of the television and decided I wanted to become a tennis player, thanks to 'Roland'.

"I stayed here in the National Training Centre when I was younger, I played in the grounds. It was my playground! This site is still very dear to me, even though the stadium has changed a lot. I qualified at age 15, I won the junior tournament.

"My career here featured many ups and downs, in part due to all those emotions I experienced when I was younger. And, after my career, I saw a different side to the event. I have coached various players, been a television pundit, a spectator and a television viewer, too. I don't know if anyone has seen the tournament from more angles than I have.

"This gives me a certain responsibility and a fierce ambition to push Roland Garros even further. The event is already fantastic, extraordinary. We are going to try and make it even better!"

Mauresmo, who retired from playing in 2009, has also served as France's Fed Cup captain.

Tennis great Billie Jean King sent a message of congratulations, and French sports minister Roxana Maracineanu welcomed the appointment.

Maracineanu said: "I salute the arrival of Amelie Mauresmo at the head of the most beautiful tennis tournament in the world. As well as being an exceptional athlete and an engaging women, she represents the necessity of tolerance and modernity. Bravo."

Novak Djokovic is chasing more records following his history-making triumph after the world number one's French Open crown brought him closer to rivals Rafael Nadal and Roger Federer in the race for tennis supremacy.

Djokovic became the first man in the Open Era to claim two or more titles at each of the four grand slams thanks to Sunday's stunning 6-7 (6-8) 2-6 6-3 6-2 6-4 victory over Stefanos Tsitsipas.

Serbian star Djokovic was two sets down on Court Philippe Chatrier, where he also became the first player in the Open Era to win a slam from two sets behind for his 19th major crown.

"I am thrilled and I'm very proud of this achievement," Djokovic – who upstaged clay specialist and defending champion Nadal in the semi-finals – told reporters afterwards. "I think part of the history of the sport that I love with all my heart is always something that is very inspiring and very fulfilling for me.

"I couldn't be happier and more satisfied with this kind of scenario in the last 48 hours. Probably ranks at the top three all-time achievements and experiences that I had in my professional tennis career. Going through a four-and-a-half battle with Rafa on his court, then bouncing back after not practicing yesterday, just coming in today with as much as recharged batteries and energy regained to fight another battle of four-and-a-half hours against Tsitsipas, who is playing in his first grand slam finals.

"It's always, of course, a bit tricky because you're playing for your trophy, for your first grand slam trophy, but you don't have much to lose. So I knew that he's going to probably start off very well, which was the case. It was a very close first set. Kind of gone a different way, but he was just the better player in those clutch moments. Second set I dropped physically and mentally I think a little bit. I just got fatigued a bit, just allowed him to kind of dominate the second set pretty much.

"Then went out from the court, as was the case against [Lorenzo] Musetti in the fourth round when I was two sets down, and came back as a different player. Just refreshed, managed to make a break, early break in the third. After that, I felt like I got into his head. I feel like I started swinging through the ball better. The momentum was on my side, it shifted. There was no looking back from that moment."

Djokovic is now just one trophy shy of equalling the record for most grand slam singles titles on the men's tour, currently shared by Nadal and Federer.

The 34-year-old insisted he will continue to chase records, with the ageing Nadal and Federer firmly in his sight.

"I never thought it was a mission impossible to reach the grand slams of these guys," Djokovic said. "I'm not there, but it's one less. But they are still playing. Obviously, they're playing great, especially Rafa with his level. We all have still opportunities at Wimbledon, all the other slams.

"You have four slams a year, so we're all competing for this amazing achievement and amazing trophies. I'll keep on going. I'll keep on chasing. At the same time, I'll keep on paving my own path, which is my own authentic path. We all three of us have our own journeys, and that's it."

Among those records is the golden grand slam – winning all four calendar majors as well as gold at the Olympic Games – with Wimbledon, the rescheduled Tokyo Games and US Open still to come in 2021 following his Australian Open success.

"Everything is possible. Definitely in my case I can say that what I've been through in my career, in my life, this journey has been terrific so far," added Djokovic. "I've achieved some things that a lot of people thought it would be not possible for me to achieve. Everything is possible, and I did put myself in a good position to go for the golden slam.

"But, I was in this position in 2016 as well. It ended up in a third-round loss in Wimbledon. This year we have only two weeks between the first round of Wimbledon and the finals here, which is not ideal because you go from really two completely different surfaces, trying to make that transition as smooth as possible, as quickly and efficiently as possible. So obviously I will enjoy this win and then think about Wimbledon in a few days' time.

"I don't have an issue to say that I'm going for the title in Wimbledon. Of course, I am. I was really happy to know that we are going to play Wimbledon this year, considering we haven't played it last year. I've had great success in the last couple of Wimbledon seasons that were played. I won in '18 and '19 there. Hopefully, I can keep that run going. I like the grass. Over the years I think I improved on grass, I adjusted my game. Hopefully, I can use this confidence that I have right now into Wimbledon, as well. Then let's take it from there."

Stefanos Tsitsipas "could easily have cried" after seeing his French Open dream crushed by Novak Djokovic but insists there is "no reason" he cannot be a future champion.

In his first grand slam final, the 22-year-old looked to be cantering to victory when he moved two sets up against the world number one.

However, much as he did in his fourth-round win over Lorenzo Musetti, Djokovic left the court before the start of the third set and returned a different competitor, going on to win 6-7 (6-8) 2-6 6-3 6-2 6-4 after more than four hours on Court Philippe-Chatrier.

Tsitsipas had little answer to the resurgent Djokovic, who became the first male player in the Open era to win every grand slam at least twice as he moved onto 19 in his career, one behind record-holders Roger Federer and Rafael Nadal.

Tsitsipas struggled to answer why his game began to let him down in the final three sets as he cut a disconsolate figure when speaking to the media afterwards.

"I felt like my rhythm was off [after the second set]," he said. "I really don't know why. It was very strange considering that I started finding my rhythm, finding my shots, my movement on the court was perfect, and suddenly just felt cold and out of it.

"It was difficult to readjust. I felt like I kind of lost my game a little bit. I really wish I could understand why things like this happened and evolved. But I was trying to figure it out during my game. It was difficult to come up with something.

"It's very unfortunate, very sad in the same way because it was a good opportunity. I was playing good. I was feeling good. Yeah, I lost an opportunity to do something better today.

"What I learned today is that no matter what, in order for the match to be finished, you have to win three sets and not two. Two sets doesn't really mean anything. It's still one away [from] winning the entire match."

Tsitsipas admitted Djokovic seemed rejuvenated as the third set got underway, saying: "He left the court after two sets to love down, I don't know what happened there, but he came back to me like a different player suddenly.

"I don't know. I have no idea. He played really well. He gave me no space. [I] felt physically, anticipation maybe, just movement on the court, everything felt much more fresh and much better than before. I kind of felt like he could read my game a bit better suddenly. Good for him. He did well to get there."

Tsitsipas, who will move to number four in the world after reaching the final, is one of the prime contenders to lead the way when the so-called 'big three' finally call time on their careers.

The Greek beat Roger Federer at the 2019 Australian Open and Rafael Nadal in Melbourne this year, while he has twice beaten Djokovic at Masters 1000 events.

"I believe, yes, I'm able to play for titles like this," he added. "Despite my loss today, I have faith in my game. I very much believe I can get to that point very soon.

"I was close today. Every opponent is difficult. There's a small difference between the player I played today and the ones from before.

"But I think with the same attitude and the same... if I don't downgrade myself, I see no reason for me not to be holding that trophy one day.

"I played two good sets. I wouldn't call them incredible. I just played really well. It wasn't enough. It wasn't enough. That's a grand slam for you. It's the way it is.

"I don't think I have regrets. Could have easily cried, but I see no reason for me crying because I tried everything. I couldn't come up with anything better."

Novak Djokovic backed Stefanos Tsitsipas to bounce back from the French Open final defeat that left the Greek star shell-shocked.

As Djokovic inked more achievements into the tennis record books, he did so at the expense of a player who surely thought his grand slam moment had come when he led the world number one by two sets.

Just as the crowd inside Court Philippe Chatrier prepared for a new champion to be crowned, Djokovic dug in, scrambling, scurrying and showing incredible levels of energy to snatch a 6-7 (6-8) 2-6 6-3 6-2 6-4 victory from what was almost a lost cause.

Having come through an exhausting four-hour battle with Rafael Nadal, the greatest of all Roland Garros champions, on Friday, it was mesmerising to watch Djokovic pick apart another world-class opponent in a marathon contest.

This was a match featuring the third largest age gap between French Open men's singles finalists in the Open Era, with Djokovic, at 34, showing a freshness that 22-year-old Tsitsipas could only admire in the closing stages. It marked the first time in Djokovic's great career that he has won a slam final from a two-set deficit.

Tsitsipas will not forget his first slam final in a hurry, but he would surely want to.

"I would like to say a few words to Stefanos," Djokovic said in an on-court interview. "I can relate to what he's going through. I understand how difficult that is, losing in the final of a grand slam.

"These are the kind of matches, the kind of occasions, you learn from the most, I think.

"Knowing him and his team, he's going to come out much stronger from this match and I definitely believe he's going to win many grand slams in the future. So respect to you and your team."

Djokovic became the first man in the Open Era to rack up two or more titles at each of the four grand slams, and he has 19 such victories altogether now, just one behind the all-time record that is shared by Rafael Nadal and Roger Federer.

"It's truly a dream to be here and play a great match for one of the great trophies in our sport," Djokovic said.

"This is a tournament that gives me a lot of inspiration. I've needed the inspiration. I'm not as young as Stefanos. I have to search every day for new inspiration.

"It's sure that my great motivations are my children and my wife and all my team, who give me so much support and love. Without them it wouldn't be possible for me to be here. I'm proud and happy."

The body language of Tsitsipas showed he was obviously crestfallen and suffering, a post-match speech just a reminder of the pain he had been subjected to at the hands of the world number one.

"It was a big fight out there. I tried my best, I tried as much as I could but Novak played better," Tsitsipas said.

"It was my first time being here in the finals. I had a good run and I'm happy with myself, but let's give it to Novak. He's showed us in the last couple of years what a great champion he is, how consistent he has been.

"I would say I'm inspired by the things he has achieved so far and I hope one day I can maybe do half of what he has done so well."

From chump to champ, bonehead to figurehead. What a difference a year makes.

On this weekend in 2020, Novak Djokovic was partying like it was, well, 2019, after the first leg of the Adria Tour, limbo-dancing in a Belgrade cabaret club, mask-free, carefree, some might say cluelessly.

Within days, he had tested positive for COVID-19, as had Djokovic's wife Jelena, along with Grigor Dimitrov, Borna Coric and Goran Ivanisevic. The tournament that Djokovic had organised was in disarray and plans to take it to five Balkan cities were abandoned when the second event in Zadar was called off before its final.

Nick Kyrgios, incredulous at home in Australia, called it a "boneheaded" decision to play the events, and Djokovic made a grovelling apology, saying he was "so deeply sorry" for the harm that had been caused.

The main tennis tours had ground to a necessary halt, but Djokovic could not resist moving, cavorting.

He might feel like hitting up a Parisian nightclub after Sunday's breathtaking comeback against Stefanos Tsitsipas in the French Open final, the first time he has come from two sets down to win a grand slam final, but even if they were open, Djokovic has probably learnt his lesson. He taught Tsitsipas a thing or two in this Roland Garros epic, too, primarily this: however much a grand slam title match feels in your control, these major finals are not like any you have played before.

So now Djokovic has 19 major titles, one behind all-time leaders Roger Federer and Rafael Nadal heading into Wimbledon in two weeks' time. He is the first man in the Open Era to win two or more titles at each of the four grand slams.

When Tsitsipas followed a thrilling opening set here by breezing through the second against the world number one, establishing a two-set cushion, his maiden slam final was going as well as he could possibly have hoped. His serve was potent, his biggest shots were landing in, and he had the measure of Djokovic's delivery: the Serbian won just 35 per cent of points on his second serve over those opening two sets.

Nine winners to just two unforced errors from Tsitsipas in that second set showed who was in charge. Djokovic had taken an early fall in the match: was that a factor?

Yet in the fourth game of the third set, Djokovic landed a punch so loaded that it caused Tsitsipas to wobble for the next hour, saving three game points on the Greek's serve before snatching the break at his own fourth opportunity.

The 11-minute game evoked memories of how Djokovic took down Nadal in their magnificent semi-final, Tsitsipas flinging a despairing backhand just wide to slide 3-1 behind, his resistance broken, his momentum gone.

Djokovic has suffered in the past following marathon grand slam semi-finals, including in Paris last October when he battled past Tsitsipas in five and then won just seven games against Nadal.

Friday's four hours and 11 minutes of hard battle against Nadal was as draining as such matches come, so from where had Djokovic found this renewed energy? Tsitsipas, seeing the title slip away, needed a big sip from whatever well from which the Serbian was drinking.

An astonishing angled drop shot from Djokovic in the third game of the decider showed his scrambling, sprinting energy was only heightening in its intensity, and he backed up that effort with a break moments later.

Tsitsipas had largely rediscovered his game, but the prospect of a pair of first-time singles champions at Roland Garros, for the first time since the Gaston Gaudio-Anastasia Myskina double in 2004, was ebbing away. It was soon all over.

After the Adria Tour howler and his US Open disqualification clanger, Djokovic began his 2021 season on a positive note with a ninth Australian Open title. Now he has a second French Open, and we can seriously start to think about a calendar year sweep of the grand slams. He has won seven of his majors since turning 30, the most by anyone in the Open Era, and it feels safe to say there are more to come.

Twelve months ago, it was a case of 'how low can you go?' as Djokovic dipped under that limbo pole.

Suddenly we can start to ask: are there no limits to the heights this remarkable man might scale?

Novak Djokovic made history in sensational fashion by storming back from two sets down to beat Stefanos Tsitsipas in a pulsating French Open final.

Tsitsipas looked to be on course to become the first Greek major champion, but legendary top seed Djokovic produced a stirring fightback to win a thriller 6-7 (6-8) 2-6 6-3 6-2 6-4 at Roland Garros on Sunday.

The indefatigable world number one etched his name in the record books on Court Philippe-Chatrier, becoming the first man in the Open Era - and only the third of all time - to triumph at each grand slam at least twice.

Djokovic had never won a major from two sets behind in a championship match but is just one shy of the record tally of 20 grand slam titles held by Roger Federer and Rafael Nadal, who he beat in an epic semi-final on Friday.

Tsitsipas appeared to be increasingly hampered by a hip injury as he endured heartbreak in his first grand slam final.

The 2016 champion won three service games without losing a point in a strong start on a sunny afternoon in Paris and there was relief when he picked himself up following a fall at speed while running at full tilt trying to retrieve return a deft drop shot.

A sprightly Tsitsipas was feeding off the energy of the crowd and had a set point after Djokovic skewed a forehand wide, but the 34-year-old showed the mentality of an all-time great to get himself out of a hole and broke in the next game when a stray forehand from the fifth seed put him 6-5 down.

Djokovic was clearly struggling with the sun in his eyes as he failed to serve out the set and Tsitsipas charged into a 4-0 lead in a brilliant tie-break, which he eventually won after saving a set point with a majestic forehand winner down the line.

Tsitsipas maintained the momentum, breaking in the opening game of the second set when Djokovic sent a forehand beyond the baseline and continuing to show rapid pace over the court.

The 22-year-old was relentless, returning superbly and unleashing a serious of glorious winners as he went a double break up before serving out the set in ruthless fashion.

Yet Djokovic hit back like he has done so many times over the years in the third set, taking a 3-1 lead by grasping his fifth break-point opportunity of a marathon game in which he put his opponent under huge pressure with a string of searing, precise returns. 

The Serbian's forehand was firing on all cylinders as he sealed the set, then broke in the first game of the fourth and again to lead 3-0 with a sublime drop shot.

Tsitsipas' unforced error count was rising rapidly and he was not moving as freely, with the wind in Djokovic's sails as he levelled the match.

World number five Tsitsipas held after saving a break point in the first game of the decider but Djokovic was not to be denied a 2-1 lead, forcing an error as he continued to show astonishing staying power along with finesse and power.

Tsitsipas showed great fight but Djokovic served out a match of such high drama to get his hands on La Coupe des Mousquetaires once again.

Barbora Krejcikova became the first woman for 21 years to win both singles and doubles titles at the same French Open as the Czech completed her staggering fortnight in Paris.

"We will have a little glass of champagne," said Krejcikova, the breakout star of Roland Garros this year, after she and Katerina Siniakova fended off Iga Swiatek and Bethanie Mattek-Sands in Sunday's doubles final.

A 6-4 6-2 victory for the Czech duo gave them a third women's grand slam title as a pair, and a second in Paris after their 2018 triumph.

Krejcikova was already established as a world-class doubles player, but it has been as a singles player that she has emerged in recent times, having only entered the WTA top 100 rankings for the first time last October.

A three-set victory over Anastasia Pavlyuchenkova in Saturday's singles final gave the world number 33 a first major title without a team-mate at her side.

The doubles triumph means the French Open women's title double has been achieved for the first time since Mary Pierce cleaned up in 2000, when the Frenchwoman beat Conchita Martinez in singles and paired up with Martina Hingis to beat Paola Suarez and Virginia Ruano Pascual.

The 25-year-old Krejcikova becomes just the seventh woman to clinch the double, after Billie Jean King, Margaret Court, Chris Evert, Virginia Ruzici, Martina Navratilova and Pierce.

Pierce wrote on Twitter: "Well done @BKrejcikova! Welcome to a very special club."

Krejcikova said she had not slept well after her singles triumph, and she felt not only tired but complained of "having some pains in my leg" after the doubles.

It has been a strenuous fortnight, and she was determined to finally unwind on Sunday evening.

"I think we going to have a dinner together this evening. We will have a little glass of champagne," she said.

"I already said I don't really drink but I think it's a time to actually celebrate it. I think we going to really enjoy ourselves.

"The rest, I just want to go back home. I just really have to relax. I have to spend some time with my family. After that, just start to work again."

Krejcikova will be a marked player at Wimbledon after her rapid rise in the rankings was capped by the slam success.

"I hope I'm going to have some chances on the grass, but I don't really know because I'm not that experienced on it," she said. "We will see.

"I just know from now on I can really enjoy because I have pretty much achieved everything I really wanted.

"Now I can just improve, that's the only thing I can do, just improving. All the guys and the ladies are doing. That's what I think."
