Matteo Berrettini continued his impressive charge at the Queen's Club Championships as he booked a place in the final against Cameron Norrie.

Top seed Berrettini, ranked nine in the world, has not dropped a set all week.

His impressive run has seen him defeat home hopes Andy Murray and Dan Evans, with one more Briton in the shape of Norrie left to see off in his bid for glory.

Berrettini ensured he will be in the final by claiming a 6-4 6-4 triumph over fourth seed Alex de Minaur in the semi-final on Saturday.

The Italian dropped just four of his 36 points on first-serve and sent down eight aces, with De Minaur only able to force one break point in the entire contest, which he did not take.

"[Making the final] was the goal of the week and now I have one more step," said Berrettini.

"It is a great achievement, especially for the history of this tournament. I am really happy because to beat Alex, I had to play my best tennis."

Berrettini has four tour titles to his name, though this would be his first at ATP 500 level or above.

Victory would also represent the biggest win of Norrie's career – he has lost each of his three previous finals, all at ATP 250 level.

Norrie impressively eliminated Denis Shapovalov to reach the showpiece, beating the Canadian 7-5 6-3.

Shapovalov had earlier finished off a 6-3 6-4 quarter-final win over Frances Tiafoe, a match that could not be completed on Friday due to fading light.

But the second seed could not muster up another victory against a fresher Norrie.

At the Halle Open, Andrey Rublev reached his eighth final since the start of 2020, though his first on a grass court.

Rublev dropped his first set of the week but ultimately prevailed with a 6-1 3-6 6-3 semi-final victory over Nikoloz Basilashvili.

The Russian has won his last four finals at ATP 500 level and will seek a fifth on Sunday.

"It's my first final on grass and in Halle," he said. "I think I can play on every surface and I will try my best again.

"I had good opportunities to break Basilashvili in the second set, some quite easy forehands and I stressed a little showing my emotions. 

"I then came back and stayed calm, until the last game. But I won."

Rublev will take on unseeded Ugo Humbert, who held his nerve to edge a thriller against Felix Auger-Aliassime, winning 6-4 3-6 7-6 (7-5).

Humbert beat Alexander Zverev earlier in the week and has had to win a deciding set in all four rounds, while the beaten Auger-Aliassime had previously seen off Roger Federer as part of a dramatic event.

Frenchman Humbert won each of his first two career finals, which both took place last year in ATP 250 events.

Top seed Matteo Berrettini has his sights set on the Queen's Club Championships title after beating Dan Evans in the quarter-finals.

After a delay of more than four hours because of rain in London, Berrettini overcame Evans 7-6 (7-5) 6-3 to reach his third ATP grass-court semi-final.

The Italian hit 13 aces and won 81 per cent of his first-serve points against Evans to set up a last-four clash with Alex de Minaur. 

Berrettini improved his win-loss record to 24-6 for the season and laid out his ambition to walk away from the tournament with the trophy.

"I didn't serve that well, but I was returning well and I just played better in the last few points of the tie-break," he said.

"After that, I felt more confident. The conditions were really tough, windy and cold, so I took time to adapt a little bit. I am pretty happy with my performance.

"The court condition was really good. I expected slippery conditions, but it was like yesterday.

"I came here to win the tournament, that is my goal. Now I am two steps away. I am happy with the way I am playing, and my mental attitude is really good."

Up next for Berrettini is Australian De Minaur, who came from behind to defeat Marin Cilic 3-6 6-3 6-4.

The 22-year-old won 73 per cent (22/30) of his second-serve points and saved six of the seven break points he faced as he moved to 16-12 for the season.

In the battle of the British players, Cameron Norrie beat Jack Draper 6-3 6-3, while Denis Shapovalov was leading Frances Tiafoe 6-3 when their match was suspended due to fading light. They will resume on Saturday.

At the Halle Open, Andrey Rublev reached his sixth ATP Tour semi-final of the year thanks to a 7-6 (7-4) 6-2 win over 2011 champion Philipp Kohlschreiber.

"I am happy with my performance to reach the semi-finals for the first time," Rublev said. "The first set was really tough. He was 3-0 up in the tie-break and I came back, which was the key.

"After the first set, I think he mentally went down and I was pumped up. I hit a couple of good returns in the first game of the second set."

Russian Rublev will face Nikoloz Basilashvili in the last four after the Georgian defeated Lloyd Harris 6-4 7-6 (7-5). 

In the day's other quarter-finals, Felix Auger-Aliassime beat Marcos Giron 6-3 6-2 and Ugo Humbert overcame Sebastian Korda 6-2 6-7 (5-7) 6-4.

Dominic Thiem has joined Rafael Nadal in announcing he will not compete at the Olympic Games in Tokyo.

The 27-year-old US Open champion pinned his decision on the belief he would struggle to find his best form, having endured a tough 2021 season so far.

Thiem has lost his last three matches, including a first-round defeat to Pablo Andujar at the French Open, and has an overall 9-8 win-loss record for the year.

World number five Thiem confirmed, however, that he intends to play Wimbledon, which begins on June 28, and will then focus on getting in the best possible shape for his grand slam title defence at Flushing Meadows.

Nadal said earlier on Thursday that he would play neither Wimbledon nor the Olympics, where the tennis tournament starts on July 24, because he wished to recover from his clay-court season efforts.

Women's tour superstar Naomi Osaka has elected to miss Wimbledon but said on Thursday she would represent Japan at her home Olympics.

Thiem revealed his Olympics decision in a statement posted on his Twitter page, saying: "After talking with my team and analysing the situation I have taken the very difficult decision to withdraw from competing in the Tokyo Olympics.

"For me, like all athletes, taking part in the Olympics and representing my country is a huge honour and that makes this decision even tougher. However, 2021 did not start as expected and I don't feel ready to play my best in Tokyo.

"These last two weeks I have been training hard – and I’m starting to improve my conditioning and concentration little by little. My goal is to work hard the coming weeks, give my best at Wimbledon and keep training and hopefully defend my US Open title.

"I wish the entire Austrian team traveling to Tokyo all the best. I am young and I hope to be able to play for Austria at the Olympics in Paris 2024."

Top seed Matteo Berrettini beat Andy Murray to reach the quarter-finals at Queen's Club and Ugo Humbert upset Alexander Zverev at the Halle Open on Thursday.

Murray, a five-time champion at Queen's, was beaten 6-3 6-3 by Italian Berrettini as the three-time grand slam champion struggled a day on from being given a Wimbledon wildcard.

The former world number one beat Benoit Paire in his first ATP Tour singles match since March on Tuesday, but the 34-year-old revealed he is still being troubled by a groin injury after his loss to Berrettini and knows he must raise his game.

Murray said: "I actually felt my movement was actually quite good for both of the matches. My tennis today was not very good. That's the thing that I'll need to improve the most.

"Then there is still a slight niggle in the groin, so [I have] to try to get rid of that discomfort between now and Wimbledon. I need to be playing points, basically. I played two sets in preparation for this event.

"I do feel like I genuinely have been hitting the ball well in practice, but then like today when you're under a bit more pressure and stuff and you're having to make very split-second decisions when you're on the court, if the guy is serving 140 miles an hour, like, it's difficult to prepare for that."

Dan Evans made history earlier in the day, getting the better of Adrian Mannarino 6-4 7-6 (9-7).

With Jack Draper and Cameron Norrie having already progressed, Evans' win ensured there will be three Britons in the singles quarter-finals for the first time in the Open Era.

Feliciano Lopez will not retain his title in London after the Spaniard went down 6-2 6-3 to second seed Denis Shapovalov. Spanish veteran Lopez won in 2019, with last year's tournament cancelled due to the pandemic.

There will be no glory on home soil in Halle for German Zverev, who was taken out 7-6 (7-4) 3-6 6-3 by unseeded Frenchman Humbert.

Humbert has now beaten a top-10 player on every surface, with Zverev serving 20 aces but bowing out after his 22-year-old opponent claimed the only break of the final set.

Sebastian Korda battled past Kei Nishikori 2-6 6-3 7-5 in Halle, while Lloyd Harris also moved into the last eight at Lukas Lacko's expense.

The US Open is set to be the first tennis grand slam to operate at full spectator capacity for its duration since COVID-19 became a global crisis.

Tournament organisers said on Thursday that the major, which was played behind closed doors in 2020, would not impose reduce attendance measures this year.

"New York is back, and so are the fans," a statement on the tournament's website said. "The 2021 US Open will welcome fans back to the USTA Billie Jean King National Tennis Center at 100 per cent capacity for the two-week tournament."

Mike Dowse, chief executive of the United States Tennis Association (USTA), said: "We are extremely excited to be able to welcome our incredible fans back to the US Open this year.

"While we were proud that we were able to hold the event in 2020, we missed having our fans on-site, because we know that they are a large part of what makes the US Open experience unlike any other.

"Indeed, the challenges presented by the pandemic were tough on us all, but our sport came together like never before and tackled each challenge head on."

Dowse added: "Our sport surged in the toughest of times, and this year's US Open promises to be an unforgettable celebration of the game, those who play it, and those who revel in it."

The tournament added that it would follow all COVID-related guidelines, although its intention clearly is to run the major in as normal a manner as is possible.

The US Open's announcement came on the day tickets went on sale for the upcoming Wimbledon championship, which begins on June 28. The grass-court slam was cancelled last year.

Wimbledon will operate at a 50 per cent attendance restriction for much of its duration, although the weekend of the finals is due to see Centre Court at 100 per cent capacity.

The French Open functioned with a vastly reduced number of tickets available in both its 2020 and 2021 editions, compared to previous years.

The Australian Open in February capped spectator numbers at 30,000, although a snap lockdown in Melbourne meant there were no crowds for five days midway through the event, with Rod Laver Arena then limited to approximately 50 per cent capacity for the closing stretch of the event.

Naomi Osaka and Dominic Thiem won the women's and men's singles titles at the 2020 US Open, and this year's tournament runs from August 30 to September 12.

Rafael Nadal will not compete at Wimbledon or the Olympic Games as he bids to prolong his prolific career.

The 20-time grand slam champion was knocked out of the French Open at the semi-final stage by eventual winner Novak Djokovic.

And, with just a two-week gap to the grass-court slam in London, the 35-year-old has opted against taking part at the All England Club or the Games in Tokyo.

"Hi all, I have decided not to participate at this year's Championships at Wimbledon and the Olympic Games in Tokyo," the Spaniard tweeted.

"It's never an easy decision to take but after listening to my body and discuss it with my team I understand that it is the right decision.

"The goal is to prolong my career and continue to do what makes me happy, that is to compete at the highest level and keep fighting for those professional and personal goals at he maximum level of competition."

Nadal explained that the quick turnaround from a gruelling campaign in Paris to another tough schedule at Wimbledon presented too much of a risk to his fitness.

"The fact that there has only been two weeks between RG [Roland Garros] and Wimbledon didn't make it easier on my body to recuperate after the always demanding clay court season," he said.

"They have been two months of great effort and the decision I take is focused looking at the mid and long term.

"Sport prevention of any kind of excess in my body is a very important factor at this stage of my career in order to try to keep fighting for the highest level of competition and titles.

"I want to send a special message to my fans around the world, to those in the United Kingdom and Japan in particular.

"The Olympic Games always meant a lot and they were always a priority as a Sports person, I found the spirit that every sports person in the world wants to live. I personally had the chance to live 3 of them and had the honor to be the flag bearer for my country."

Nadal is a two-time Wimbledon champion and took gold at the 2008 Olympics in Beijing.

Roger Federer lost in the opening two rounds at the Halle Open for the first time in his career as his hopes of winning the title for the 11th time were ended by Felix Auger-Aliassime.

Federer beat Ilya Ivashka in his opening match of the grass-court season at a tournament defined by his dominance in Halle.

He came into Wednesday's clash with Auger-Aliassime boasting a 32-0 record in the first two rounds, and that looked set to be preserved after the 20-time grand slam champion won the first set.

But Auger-Aliassime, exactly 19 years Federer's junior, staged a stunning fightback in a contest with the largest age difference of the Swiss' 1,521 career matches.

His remarkable turnaround saw the Canadian claim a 4-6 6-3 6-2 triumph that marked the fourth top-10 win of his career.

It also meant he denied Federer a 70th match win in Halle and his 18th quarter-final in as many appearances at the tournament.

"It's a great victory, it's good for my confidence. It was already a great challenge for me to play a player like Roger, but to beat him, it's a great thing," Auger-Aliassime said. "It makes me really happy. But at the end, it's the quarter-finals in two days. 

"If it was the final, then I'd be really happy… it's another step in the tournament, it's a great match, so hopefully I can keep on going like that.

"In the first set, I didn’t think I could have played much better outside of just missing one forehand in my service game and then he hit two amazing passing shots and I was just like 'Whoa'.

"I understand how good he is and how good he was when he was No. 1 in the world, so it was tough.

"Everything worked well today, to be honest. I think that's what you need to do against Roger. On my part, I served really well. I was able to put in a lot of returns, mix up coming to the net, closing well. I think overall I did a good match."

Marcos Giron is next for Auger-Aliassime after he overcame Jan-Lennard Struff in three sets. There were straight-sets wins for Andrey Rublev over Jordan Thompson and Philipp Kohlschreiber over Corentin Moutet. Rublev will face Kohlschreiber in the last eight.

Wednesday's play at the Queen's Club Championships saw Alex de Minaur win an all-Australian clash with John Millman, while Britons Cameron Norrie and Jack Draper defeated Aslan Karatsev and Alexander Bublik respectively.

Former world number ones Andy Murray and Venus Williams have been given Wimbledon wildcards.

Three-time grand slam champion Murray missed the French Open to focus on the grass-court season, having been troubled by a groin injury.

The 34-year-old Brit, ranked 124th in the world, was emotional after beating Benoit Paire 6-2 6-2 in his first ATP Tour singles match since March on Tuesday.

Murray's career was in doubt after he underwent hip resurfacing in 2019, but the 34-year-old double Wimbledon champion will play in his home major at the All England Club.

Williams, a winner of five Wimbledon singles titles and a six-time doubles champion at the grass-court major, also received a wild card after dropping out of the top 100 in the rankings.

The 40-year-old American will be in the singles draw 21 years after winning her first Wimbledon title.

Wimbledon did not take place last year due to the coronavirus pandemic, but will be the first major outdoor sports in England to be staged with full capacity crowds for the finals weekend of July 10-11.

The Championships will start at SW19 on June 28 with 50 per cent capacity across the venue grounds, Centre Court and No.1 Court. Smaller show courts will be allowed to open at 75 per cent capacity from day one.

From the fourth round, the aim is to increase allocations for Centre Court and No.1 Court, rising to 100 per cent for the finals.

Andy Murray had to hold back the emotion as he celebrated a winning return to the ATP Tour at Queen's.

Murray had hip surgery in 2019 and had not won a grass-court game since 2018, with last year's season having been cancelled due to the coronavirus pandemic.

Having struggled with a groin injury, the 34-year-old Scot last played in March, yet showed flashes of his old self in his 6-3 6-2 victory over Benoit Paire, having taking up a wildcard into the pre-Wimbledon tournament.

It was an emotional moment for Murray, who said: "Look, I love playing tennis."

The five-time champion was fighting back the tears as he continued: "Obviously, competing is why you put in all the hard work.

"The last few years, I've not got to do that as much as I would have liked so, yeah it's just great that I'm out here and able to compete again.

"The body is old, but I did quite well today in terms of my movement.

"It's my first match on grass in three years and I've only played three or four practice sets in the build-up to this, so I didn't know exactly how I was going to play or feel – but I think for a first match it was good."

Murray will face top seed and world number nine Matteo Berrettini, who defeated Stefano Travaglia 7-6 (7-5) 7-6 (7-4).

British number one Dan Evans beat Alexei Popyrin, while fourth seed Alex de Minaur also progressed to round two, having come from behind against Laslo Djere. Second seed Denis Shapovalov overcame Aleksandar Vukic.

Tuesday's results mean, for the first time since 2005, four British players have won at Queen's, with Cameron Norrie and Jack Draper having gone through on Monday.

Meanwhile, after losing to Stefanos Tsitsipas in the French Open quarter-finals, world number two Daniil Medvedev crashed out of the Halle Open in the first round.

Jan-Lennard Struff was his conqueror, claiming a 7-6 (8-6) 6-3 triumph, which the German labelled as "the biggest win of my career."

There was better luck for third seed Alexander Zverev, though he did need three sets to see off Dominik Koepfer 6-4 3-6 6-3, just four days after facing Tsitsipas in the Roland Garros semi-finals.

Ugo Humbert awaits Zverev, while Felix Auger-Aliassime beat Hubert Hurkacz to tee up a tie with Roger Federer. World number seven Andrey Rublev got the better of Karen Khachanov.

There will be capacity crowds for the Wimbledon finals next month and around 45,000 people are set to be allowed into Wembley for the Euro 2020 semi-finals and final.

Prime Minister Boris Johnson on Monday announced a four-week delay in lifting coronavirus lockdown restrictions in England to July 19 due to rising cases of the Delta variant.

However, Wimbledon and the European Championship are being treated as test events, so there is set to be a full house of 15,000 on Centre Court for the championship matches on the weekend of July 10-11.

The grass-court grand slam will be the first outdoor sporting event to have a capacity crowd since the start of the pandemic.

When the tournament, which was not staged last year due to the COVID-19 crisis, starts on June 28 it will be at 50 per cent capacity.

A statement from the All England Club said: "We are pleased to have worked closely with the government, public health bodies, and our local authority in Merton, to confirm that, as part of this next phase of pilot events, The Championships 2021 will begin on Monday 28 June with 50 per cent capacity across the Grounds, building to full capacity crowds of 15,000 on Centre Court for the finals weekend.

"This will enable us to fulfil our aspiration of staging the best Wimbledon possible within the current circumstances, with the health and safety of all those who make Wimbledon happen - our guests, competitors, members, staff, media, officials, local residents, and partners - remaining our highest priority."

Crowds for England's first two Euro 2020 group games at Wembley have been capped at 22,500, but that figure is expected to be doubled so the stadium is half full for the semi-finals and final.

The semi-finals will be staged on July 6 and 7, with the final held on July 11.

Culture Secretary Oliver Dowden said: "We want to gather further evidence on how we can open up all big events safely, and for good.

"The expansion of trials of the NHS app and lateral flow testing will mean that bigger crowds will be able to attend a limited number of major sporting and cultural events early this summer as part of our events research programme.

"In the next few weeks, this means more fans enjoying the Euros and Wimbledon, and some of our biggest cultural and sports events."

Roger Federer returned to action at the Halle Open on Monday and won his first match on grass since the 2019 Wimbledon final.

Federer has endured two torrid years on the ATP Tour, missing most of 2020 due to double knee surgery.

The 20-time grand slam champion had then been limited to six matches this season heading into this week.

Having finally found some momentum at the French Open, Federer withdrew from his fourth-round match and explained: "It's important that I listen to my body and make sure I don't push myself too quickly on my road to recovery."

But the Swiss great was fit to finally step back out on a grass court for the first time since coming up short against Novak Djokovic at the All England Club.

And it was a winning return as Federer battled past Ilya Ivashka 7-6 (7-4) 7-5 in Germany.

Ivashka squandered two break point opportunities early in the opener and was quickly on the back foot after the set went to a tie-break, saving three set points but not a fourth.

Federer stayed patient in a second that stayed on serve initially, belatedly piling on the pressure to break in the final game having earlier passed up a match point at 5-4.

Fifth seed Federer was the only seed to win on Monday, however, as Sebastian Korda upset Roberto Bautista Agut in straight sets and David Goffin gave Corentin Moutet a walkover.

There was a standout shock at the Queen's Club Championships, too, as talented teenager Jannik Sinner was pipped by home hopeful Jack Draper 7-6 (8-6) 7-6 (7-2).

Draper's compatriot Cameron Norrie joined him in the last 16, battling back to beat Albert Ramos-Vinolas in three.

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?
