Swimmer Caeleb Dressel led the way with five golds as the United States finished top of the medal table at the Olympic Games for a third successive time.

Team USA's haul of 113 medals at the Tokyo Games – comprising 39 gold, 41 silver and 33 bronze – was 25 more than second-placed China, while Japan finished third.

The 58 medals won by the hosts set a record for the most they have ever won at a single Olympics, including 27 golds – 11 more than their previous record from 1964 and 2004.

Italy (40 medals), the Netherlands (36), Brazil (21), New Zealand (20), Turkey (13) and Chinese Taipei (12) also enjoyed their best ever Games showings.

In all, 93 different competing nations claimed a medal in Tokyo, which is more than any other edition of the global showpiece, surpassing the previous record of 87 set in 2008.

That includes first ever Olympic medals for Turkmenistan, San Marino and Burkina Faso in weightlifting, shooting and athletics events respectively.

Indeed, with a population of around 34,000 people, San Marino are now the smallest nation to win an Olympic medal.

MCKEON IN SEVENTH HEAVEN

Twenty of Australia's 46 medals came in the pool, with swimmer Emma McKeon responsible for seven of those – at least two more medals than any other athlete in Tokyo.

In doing so, the 27-year-old became the second female athlete to claim seven or more medals at a single Olympics after Maria Gorokhovskaya in 1952.

Dressel swept up five golds in the men's swimming events, meanwhile, to become the 10th athlete to reach that tally at a single Games.

Away from the Aquatics Centre, it was an Olympics to remember for Elaine Thompson-Herah as the Jamaican became the first woman to win both the 100 metre and 200m sprint at two Games.

Further success came for Thompson-Herah in the 4x100m relay, making her only the second woman to win five athletics golds after Allyson Felix (seven).

The Netherlands' Sifan Hassan also wrote his name in the record books by becoming the first athlete to win a medal in the 1500m (bronze), 5000m (gold) and 10,000m (gold) at the same Games.

Indeed, Hassan is the first track and field athlete to claim a medal in three individual disciplines since Carl Lewis and Heike Drechsler in 1988.

AGE IS JUST A NUMBER

Japanese skateboarder Momiji Nishiya became the youngest Olympic gold medal winner since 1960 – and third-youngest of all time – with victory in the women's street event at the age of 13 years and 330 days.

At the opposite end of the spectrum, 62-year-old Andrew Hoy of Australia became the oldest medallist at the Olympics since 1968 with a silver and bronze in the equestrian competitions.

Judokas Hifumi Abe and Uta Abe kept it in the family by becoming the first brother and sister combo to claim gold medals at the same Olympics when winning the men's -66 kilograms and women's -52kg events respectively.

July 28 proved to be a day to remember in more ways than one for Olga Frolkina and Evgeniia Frolkina, meanwhile, as the twin sisters took silver in the 3x3 basketball on their 24th birthday.

Andrea Petkovic claimed her first singles title on the WTA Tour in over six years thanks to an emphatic victory over Mayar Sherif at the Winners Open.

Petkovic was far too strong for her Egyptian opponent in Sunday's final, easing to a 6-1 6-1 triumph after just over an hour on court in Cluj-Napoca.

The impressive result sealed the German a seventh tournament win in her career, though she had not reigned at an event since her success in Antwerp back in February 2015.

Sherif had become the first Egyptian to reach a singles final on the WTA Tour and received praise from her opponent during the presentation ceremony.

"This has been a great week, but not only that, what's really important is you're paving the ground for all the girls in a part of the world which doesn't appreciate tennis as much as we do here in Europe," Petkovic said to the 25-year-old.

"It's so much more important than winning every title every week, though I'm sure you will get there as well. 

"Just being out there competing, being the first Egyptian woman to make a WTA final, to break into the top 100, I think that's incredible. I want to congratulate you on that – keep going."

Petkovic raced into a 5-0 lead in the opening set before Sherif held serve; she also survived two break points to move ahead at the start of the second.

However, the second seed reeled off the next six games in a row, clinching the result with a forehand winner.

MotoGP championship leader Fabio Quartararo enjoyed a "good day" at the Styrian Grand Prix, as his podium finish and Jorge Martin's win extended his lead at the top of the standings.

Quartararo finished third in a race that was suspended for half an hour due to an early crash, which saw two bikes engulfed in flames.

Both riders – Dani Pedrosa and Lorenzo Savadori – escaped relatively unscathed, though the latter was unable to restart the race.

The restart benefited Martin, who had set a record time at the Red Bull Ring to take pole position in Saturday's qualifying session.

Francesco Bagnaia had overtaken the Pramac Racing rider but, despite an early attack from Jack Miller after the restart, Martin recovered to cruise to his maiden MotoGP triumph.

Behind Martin, Joan Mir (Suzuki Ecstar) claimed second, with Quartararo nipping into third – Miller's hopes fading when he skidded off the track at Turn 7 with 10 laps remaining.

Quartararo (172) now has a 40-point lead over Johann Zarco, who finished sixth, in the championship standings, with Mir further behind on 121.

"It feels so good because when there is a red flag it is always tough," said Quartararo.

"I was extremely good on the braking on Turn 3. I knew that there was a possibility to overtake and did it.

"I don't really know the position of the other guys apart from Joan and Jorge finishing in front. I am so happy. The best goal was to finish on the podium and we did it. So happy for Jorge, he took some points off Joan, so a good day."

Martin, meanwhile, was ecstatic after achieving what he labelled the first step on his path to pushing for world championship glory.

"I can't believe it, I don't believe it, that's why I'm not so excited! I think the ride was amazing. I kept a really constant pace. I was super focused," said the 23-year-old.

"Even if I did some mistakes, my target was to win the race. Joan was impressive today, he was behind me almost all the race but then in the last laps I tried a bit more and I took a gap for the lead.

"The last laps I was thinking about things – everyone who has helped me to be here – that's why I did worse in the last laps but I had this gap to manage. Thanks to all my family, this is one big step towards my big area to be world champion."

Reigning world champion Mir said: "Today was close. I'm happy because all weekend we have been there, overall.

"I needed a couple of faster laps to fight with Jorge, he did a great job. We must push a bit more, find something more for next weekend if we want to be on the top of the podium.

"I am proud of the team, they have done a great job and finally, the performance is higher, so happy and proud of them."

Kenya's Eliud Kipchoge successfully defended his men's marathon title and the United States added three more golds to their tally on the final day of Tokyo Olympics action.

Kipchoge crossed the line one minute and 20 seconds ahead of runner-up Abdi Nageeye to become the third athlete to win the event at back-to-back Games.

In doing so, the 36-year-old – who previously took 5,000 metre silver in 2008 and bronze in London four years later – believes he has inspired a generation of runners.

"It means a lot to me, especially at this hard time," he said. "Last year was postponed, and now it has happened.

"I think I fulfilled the legacy by winning the marathon for the second time. That's my total happiness, my inspiration for the next generation."

The final day of action at the 2020 Games ultimately belonged to the United States, though, as they collected three golds to finish above China at the top of the medal table.

USA TRUMP CHINA

Team USA trailed China by two gold medals heading into Sunday's events, but triumphs in basketball, volleyball and track cycling saw them top the standings.

USA's victory in the women's basketball would have come as little surprise given it is their seventh straight success in the competition.

Brittney Griner racked up 30 points and Breanna Stewart also impressed in the 90-75 win over Japan with 14 points, 14 rebounds, five assists, four steals and three blocks.

Sue Bird and Diana Taurasi each picked up their fifth gold medals, while for Japan the silver was their first medal of any sort in the sport.

"The only thing about getting older, you know all the bad stuff that can happen," Bird said. "We lost in the 2006 World Cup. We tasted that and that's always been the driver. 

"So, when we actually have the medal around our necks, it just feels so good. It's a sense of relief in a lot of ways."

While success in the women's basketball is par for the course, overcoming Brazil in the volleyball final provided USA with their first gold medal in the event.

After finishing runners-up to Brazil in the 2008 and 2012 Games, USA exacted some revenge with a 25-21 25-20 25-14 victory in Sunday's final.

Jennifer Valente completed the hat-trick for the Americans in the women's cycling omnium, the 26-year-old delivering her country's first track cycling gold since 2000.

She led from start to finish, despite crashing in the final points race, with home favourite Yumi Kajihara taking silver.

"There were some bumps. It was actually quite a short day as far as omnium goes," Valente said. "That was something that was very much on my mind, that we played into.

"Crashing in the point races is never ideal. I was just trying to get back on my bike, make sure I was okay, and get back in the race as soon as possible."

BRITAIN RULE THE TRACK

Kelsey Mitchell won the women's sprint for Canada by beating Ukraine's Olena Starikova 2-0 in the best-of-three final.

But it was a familiar outcome in the men's keirin as Jason Kenny finished 0.763 seconds ahead of Azizulhasni Awang of Malaysia to win his seventh Olympic gold medal.

That makes Kenny Great Britain's most decorated Olympian and ensured Team GB finished top of the cycling medals table with six golds, four silver and two bronze.

"It's a bit of shock, I think," Kenny said of his latest medal success. "I really wanted to cross the finish line. I am absolutely buzzing. 

"Going into the final I didn't expect anything other than a five, really. I was hoping to kind of get stuck in, and hopefully come away with some silverware. 

"To win at the corner on my own like that is absolutely buzzing."

AMERICA'S BOXING WAIT GOES ON

The final four boxing gold medals were up for grabs on Sunday and plenty of focus was on the super-heavyweight bout between Bakhodir Jalolov and the USA's Richard Torrez. 

Twenty-two-year-old Torrez started strongly with a ferocious assault in the first round, but Uzbekistani boxer Jalolov recovered and won unanimously.

Torrez's compatriot Keyshawn Davis earlier lost his men's lightweight clash with Cuba's Andy Cruz, meaning USA's wait for an Olympic men's boxing gold will reach 20 years come Paris 2024.

"I've never felt this much pressure in fights a day in my life," Davis said. "I'm glad I got to experience this because it did make me a better fighter.

"I'm not cool with winning silver, but it's something I've got to live with and I'm okay with that. I'm gonna live with it and we're just gonna take it to the next level."

In the female categories, Kellie Anne Harrington beat Brazil's Beatriz Ferreira in the lightweight final to earn Ireland their second gold of the Games, while GB's Lauren Price outclassed Li Qian to win the middleweight final on points.

No play was possible on the final day of the first Test between England and India, with persistent rain in Nottingham wiping out the possibility of an intriguing finish to the series opener.

India had been due to resume their second innings on 52-1 requiring a further 157 for victory, Rohit Sharma and Cheteshwar Pujara the unbeaten batsmen with both on 12 not out.

However, the players never made it out onto the field as bad weather at Trent Bridge meant an absorbing contest, one that had ebbed and flowed through the four previous days, finished in a rather disappointing draw.

England had set their opponents 209 thanks mainly to an outstanding century from captain Joe Root, his 21st in Test cricket but first on home soil since September 2018.

Jasprit Bumrah's five-wicket haul made sure India were not chasing too many, with the tourists only losing opener KL Rahul – caught behind off the bowling of Stuart Broad for 26 – in a tricky 14-over spell prior to the close on Saturday.

Yet the English weather had the last word on proceedings, meaning the teams remain at 0-0 in the five-match series as the focus quickly switches to the second Test, which begins at Lord's on Thursday.

Son Heung-min scored the only goal as Tottenham rounded off an unbeaten pre-season by edging out rivals Arsenal 1-0 in the final game of the Mind Series on Sunday.

A tight affair was settled in the 79th minute at the Tottenham Hotspur Stadium, with Son receiving Japhet Tanganga's square pass in the box before firing past Bernd Leno.

Three wins and two draws from their five pre-season games means Nuno Espirito Santo's side head into the Premier League campaign, which begins against reigning champions Manchester City on August 15, unbeaten.

Despite Spurs' victory here moving them level on points with Chelsea, the Blues win the mini-tournament having scored the greater number of goals in their two matches.

Chances were few and far between for the most part. Leno denied Son from point-blank range, while Alexandre Lacazette hit the post from the edge of the box.

Though it was technically a friendly, the competitive nature of the fixture was evident with a crunching Dele Alli tackle on Nicolas Pepe earning a yellow card.

Alli twice went close to breaking the deadlock; the England international hitting the post either side of half-time.

The game appeared to be heading for a stalemate but Son – a scorer in two of the three most recent competitive encounters between the sides – snatched the victory for Spurs 11 minutes from time with his third goal of pre-season.

Mikel Arteta's Arsenal, who launch their Premier League season away at Brentford on August 13, had a chance to equalise late on, but Pierluigi Gollini denied Bukayo Saka from close range.

IOC president Thomas Bach hailed the athletes of Tokyo 2020 for offering the world "the most precious of gifts" in the form of "hope" before bringing the Games to a close on Sunday.

There was plenty of scepticism throughout Japan, and indeed across the globe, about the practicality of hosting an Olympics in the midst of a pandemic.

Bach and the Olympics organisers remained steadfast in their belief the Games – delayed by a year due to the proliferation of COVID-19 – should go ahead, though, and Tokyo 2020 has played out without major incident over the past two weeks.

Speaking at Sunday's closing ceremony, Bach reiterated the message of solidarity he heeded when opening the 32nd Olympiad a little over two weeks ago.

"Dear athletes, over the last 16 days you have amazed us with your sporting achievements, with your excellence, with your joy and with your tears. You created the magic of these Olympic games Tokyo 2020," he said.

"You were faster, you went higher, you were stronger, because we all stood together in solidarity. 

"You were competing fiercely with each other for Olympic glory and at the same time you were living peacefully together under one roof at the Olympic village. This is a powerful message of solidarity and peace. 

"You inspired us with this unifying power of sport, this is even more remarkable given the many challenges you had to face because of the pandemic. In these difficult times you gave to the world the most precious of gifts. Hope. 

"For the first time since the pandemic began the entire world came together, sport returned to centre stage, billions of people around the globe were united by emotion, sharing moments of joy and inspiration. This gives us hope, this gives us faith in the future, the Olympic games Tokyo 2020 are the Olympic games of hope, solidarity and peace. 

"You the best athletes of the world could only make your Olympic dream come true because Japan prepared the stage for you to shine. You the Japanese people can be extremely proud of what you have achieved. On behalf of all the athletes we say thank you Tokyo, thank you Japan.

"And now I have to mark the end of this most challenging Olympic journey. I declare the Games of the 32nd Olympiad closed."

Seiko Hashimoto, president of the Tokyo Organising Committee of the Olympic and Paralympic Games, added: "The athletic events of the past 17 days have inspired us, given us courage, and shown us hopes for the future.

"I would like to express my feelings of gratitude and respect to all the athletes, and to everyone else who overcame so many difficulties to so thoroughly prepare for these Games and deliver their absolute best performances."

USA football star Megan Rapinoe got to see her fiancee Sue Bird complete a stellar Olympic career with a fifth basketball gold medal - despite all crowds being banned in Tokyo.

Bird, 40, signed off her Games career in the United States' 90-75 win over Japan on Sunday.

At courtside was Rapinoe, who won a bronze on Thursday when she scored twice as the USA beat Australia 4-3 in the football third-place match.

Rapinoe, who won the Golden Boot and Golden Ball at the 2019 World Cup, first met Bird in the run-up to the 2016 Rio Olympics.

They became a couple later that year and announced their engagement in October 2020.

When the USA clinched the basketball gold medal, Bird went to the side of the court and kissed Rapinoe, later revealing how her 36-year-old partner managed to gain access to the Saitama Super Arena.

"I'm very lucky," Bird said. "Obviously when your partner or your fiancee is also in the Olympics you would love to be able to go and support them, be around them, to give any kind of support possible.

"Megan somehow finagled a media credential and got herself in this arena today. We didn't really know it was going to happen until two days ago, it got confirmed. So I do I feel very lucky she was here to witness it, to share it with me."

Spectators have been blocked from attending venues at the Olympics due to the COVID-19 pandemic, with families of overseas athletes unable to travel to Japan for the Games, meaning Rapinoe was among the fortunate few to be in the arena.

"I just went over and obviously told her I loved her and told her I was tired," said Bird. "That was pretty much the extent of the conversation, and she told me she was happy and proud of me.

"Of course I'm so proud of her and her team for winning that bronze medal. The Olympics is hard. It's really hard. There's so much pressure involved and so to have both of us medal is something that I know we'll take that memory with us forever."

Rapinoe wrote on Instagram: "I am so proud of you @sbird10. As if I could love you any more. Congrats baby!"

Bird has ruled out playing on to Paris 2024, happy to settle for five gold medals, the first of which came in Athens at the 2004 Games.

"It really is hard to wrap your head around it, to grasp what it is," said the Seattle Storm star.

"Twenty years of staying true to the game, making sure you're at the top of your game, so much sacrifice.

"The only thing about getting older, you know all the bad stuff that can happen. We lost in 2006 [to Russia at the World Championship]. We tasted that and that's always been the driver.

"So when we actually have the medal around our necks, it just feels so good. It's a sense of relief in a lot of ways."

Philippe Coutinho is set to make his long-awaited return from injury in Barcelona's Joan Gamper Trophy showdown with Juventus on Sunday.

The Brazilian has been passed fit and could play his first football for Barca of 2021, having undergone two knee surgeries since the turn of the year.

The attacking midfielder last played for the Catalan giants in their 1-1 draw with Eibar at the Camp Nou in December.

Ronald Koeman has also named the likes of Memphis Depay, Antoine Griezmann and Martin Braithwaite in his 21-man party for the club's annual season curtain raiser at Estadi Johan Cruyff.

However, Sergio Aguero and Clement Lenglet are missing for Barca, who begin their LaLiga campaign at home to Real Sociedad on August 15.

Aguero, who arrived from Manchester City on a free transfer, is set to undergo further tests on a right calf injury, while defender Lenglet has a tendon problem in his right knee.

Barca are seeking their ninth successive victory in the Joan Gamper Trophy, which they have won 43 times since the inaugural event in 1966.

Juventus, who launch their Serie A season away at Udinese on August 22, are one of the 11 teams to have denied the Blaugrana.

The Bianconeri prevailed on penalties in the 2005 showpiece.

Keyshawn Davis and Richard Torrez Jr could not end the USA's long wait for a men's Olympic boxing gold medallist, meaning the drought will reach 20 years by the time Paris 2024 rolls around.

On the final day of Tokyo 2020, there were high hopes that lightweight Davis and super heavyweight Torrez Jr could top the podium at the Kokugikan Arena.

Yet Davis lost on a split decision to Cuba's Andy Cruz in his final, and Torrez Jr was thwarted by Uzbekistan's Bakhodir Jalolov.

The two silver medals mean Andre Ward's light heavyweight gold at Athens in 2004 remains the last time an American man landed boxing glory in the Games. 

A devastated Torrez Jr said: "I feel like I had the world in my hands, and it slipped. And I watched it fall and break, and I'm trying to pick up the pieces.

"I've been on the medal podium before, and it's one of the best and worst feelings to ever feel. To not have that flag raised, to not have that anthem played, to sit there and one guy is crying tears of the joy, the other sadness. When you are in that position it's really tough. So maybe one day I'll look back and say I did a good job, because I do believe I did a good job, but it's tough.

"This is one of the most bittersweet moments I've ever felt."

The 22-year-old said the US men "fought their heart out" in Tokyo, with each man mindful and perhaps burdened by the unusually long wait for a place on the top step of the podium.

"I think overall as a team, we are putting boxing back into the USA. I do believe that we are giving it a surge again," Torrez Jr added. "I believe it's coming, I really do. I'm sorry I couldn't be the one to do it, but I have pride and I have belief in my country."

Davis was somewhat less lyrical in reflecting on his loss, saying of his experience in Japan: "It was something I never experienced before. Putting my professional career on hold to complete something, this is the hardest in the world to complete. I came up a little short, but leaving this tournament I'm a completely different fighter.

"I'm glad I got to experience what I experienced at this Olympics, and it's something I will remember for the rest of my life."

HOLMES WHERE THE HEART IS FOR PRICE

Great Britain's Lauren Price is a former international footballer and kickboxer who can now call herself an Olympic boxing champion.

The Welsh middleweight beat China's Li Qian on a unanimous verdict, even winning all three rounds with four of the five judges, and the 27-year-old revealed her inspiration came from the Athens Olympics.

British track star Kelly Holmes won 800 metres and 1,500m gold medals in the Greek capital, delivering on years of promise and effort at the highest level in athletics, and a watching Price was inspired.

"I've got to say today tops anything I've ever done in my career. It's been a dream of mine since I was eight years old watching Kelly Holmes win that gold," Price said.

"I've always said I didn't know how I was going to get here and what sport I was going to do, but the dream has always been to get to the Olympic Games.

"To win gold is just the icing on the cake and I can't really put into words what it means to me right now."

HARRINGTON CLEANS UP

Irish lightweight Kellie Anne Harrington fended off Brazilian Beatriz Ferreira to land gold in the first fight of the day, then promised she would soon be back to her cleaning job at St Vincent’s Hospital in Dublin.

The 31-year-old said: "I’m an Olympic champion but it doesn't define me as a person. At home, I'd say it will be a bit mental, but I will be going back to work in two or three weeks. I'll be back at work, back doing my normal thing, that's what keeps me grounded.

"My circle [of friends] is very small and it will be staying very small. I'm going to just keep doing what I do. Nothing will change. I won't start thinking I'm something that I'm not. This is me. I will continue to be this way - except I'll have my gold medal.

"I'll get home, have a break, eat loads of pizza. I'm sure there will be a little party in work for me and I'll be bringing my medal there."

Roger Federer turned 40 on Sunday amid uncertainty over whether he will grace the stage of a grand slam again.

Both he and Serena Williams, who reaches the same birthday landmark in September, have kept their future plans under wraps.

However, it would come as no surprise now if one, or both, were to retire by the end of the year.

Injuries are taking their toll, and even the greatest champions cannot go on forever.

Stats Perform looked at both Federer and Williams, considering what they may still want to achieve, and their prospects of attaining those remaining goals.

Federer's final fling?

Ahead of his 30th birthday, Federer was asked what it felt like to hit such a milestone.

"Birthdays happen. They're part of life," Federer said. "I'm happy I'm getting older. I'd rather be 30 than 20, to be honest. To me it's a nice time."

A decade on, Federer has good reason to be satisfied with life as he chalks up another decade. Family life is good, he'll never need to borrow a dollar, and he has advanced from 16 grand slams to 20.

But the knees would sooner be 30 than 40, and Federer, remarkable sportsman though he is, looks to have entered the lap of honour stage of his career – if he can even complete such a lap.

Two knee operations in 2020 were followed by a setback that ruled him out of the Olympics and will also keep him sidelined for the Toronto and Cincinnati tournaments before the US Open.

Will Federer make it to Flushing Meadows, where he won five successive titles at the height of his career? There has to be doubt over that, and should he indeed be an absentee in New York, what is there left to target? The Laver Cup, perhaps, a tournament in which he is financially invested and which is due to be played in Boston in late September.

Would he play on in 2022? Could he tolerate more long road trips without his family, living in a tennis bubble?

Target: Federer has never settled for second best, and it may have dawned on him at Wimbledon that in all probability he no longer can win a grand slam. Losing a 6-0 set to Hubert Hurkacz on the way to a quarter-final exit would have hurt. The hunger does not go away after 20 grand slams, but Federer's battle-weary body is sending him messages. He will want to go out on his own terms, which means getting fully fit.

Prospects: Assuming the knee issue is not a major problem, and more of a niggle, then Federer could still play the US Open, Laver Cup, Indian Wells and Paris Masters this year. If the mind is willing but the body does not comply, however, then it would not be a shock to see him call time before the Australian Open comes around in January.

Serena still one short of Court

From precocious teenager to queen of the tour, Williams' tennis journey has been a 25-year odyssey and there is nobody more driven to succeed than the great American.

It is an intense frustration that she remains rooted on 23 grand slams, one short of Margaret Court's record haul, and the four grand slam final losses she has suffered while on that mark have been cruel blows.

As her 40th birthday approaches on September 26, prospects of matching Court are fading. The leg injury that cruelly forced her out of Wimbledon in the first round was a harrowing turn of events, given she looked primed to be a big title challenger in London.

She is becoming less of a factor when looking at title favourites, but Williams is still capable of beating top players, still a threat wherever she shows up. It comes down to whether the body lets her chase her goals, and whether the pain of so many near-misses in recent years persuades this great champion the exertion is no longer worth prolonging.

Target: The 24th slam has been the must-have for Williams. Tour titles feel like an irrelevance, and Williams has won just one of those since January 2017, her calendar built around peaking for the majors since returning from giving birth to daughter Olympia.

Prospects: Beating Aryna Sabalenka and Simona Halep at the Australian Open demonstrated Williams still has the game for the big stage, and a semi-final defeat to Naomi Osaka, to whom she has now lost in three of four encounters, should not particularly detract from that. Wimbledon felt like a golden opportunity, with a host of major rivals absent and others struggling for form. There is no doubt she felt that way. Getting to 24 – and beyond – has shifted from feeling like an inevitability to being an odds-against chance now.

Novak Djokovic led the ATP Tour's birthday message to Roger Federer, as the Swiss star celebrated his 40th on Sunday.

Federer, ranked ninth in the world, made his professional debut in 1998. He has gone on to win 20 grand slam titles, a feat matched by only Rafael Nadal and Djokovic, who tied his rivals with his triumph at Wimbledon in July.

His first grand slam title arrived at Wimbledon in 2003, when Federer was aged just 21. In 2004, 2006 and 2007, he won three out of the four majors on offer.

Federer has six Australian Open titles, eight Wimbledon triumphs, five US Open wins and one French Open success to his name, while he has also won six ATP Tour Finals.

Djokovic and Federer have met 50 times on the ATP circuit, with the Serbian shading their head-to-head record with 27 wins – their most recent encounter coming in the semi-finals of the 2020 Australian Open.

Yet it was he who led the tributes to a true great.

"Hey Roger, happy 40th birthday – 40th, wow, what a milestone! You still keep on inspiring and thriving on the court, off the court, inspiring all of us," Djokovic said in a video posted to the ATP Tour's official Twitter account.

"It's been a huge honour to share the tennis court and the tennis circuit with you in the last 15 years.

"Hopefully you can still keep on playing. The sport needs you, of course, and thanks for everything you have done and thanks for showing us that even at that age we can play at a very high level.

"All the best, I wish you health and love and happiness with your close ones and thanks again for everything."

Kei Nishikori, who has beaten Federer three times and suffered eight defeats to the Swiss, was next up.

"Roger, happy 40th birthday!" Nishikori said.

"You are still my idol, I always looked up to you and I hope we can play a couple more times and I hope you can still keep going and win grand slams."

World number 15 Felix Auger Aliassime shares his birthday with Federer, though the Canadian is some 19 years junior.

"Hey Roger, the big 40, while I'm just turning 21," he said. "It's amazing for the sport that I'm playing and you're still playing at the same time.

"I hope I'll still be playing when I'm 40 as well. Thank you for everything you've been doing for tennis, it's so good to still have you around, I hope you have a great birthday."

The United States finished top of the Tokyo Olympics medal table after a stunning run of success from their elite women on the final day of competition.

Triumphs in basketball, volleyball and track cycling saw Team USA move to 39 gold medals for the Games, pipping China at the post.

China finished with 38 golds, meaning that for the third successive Olympics it is the United States who hold sway on the medals front.

The all-conquering women's basketball team were 90-75 winners over Japan in their final, landing gold for a seventh successive Olympics.

They last lost at the Games in 1992 at Barcelona and were never in danger of surrendering their undefeated streak since, as Sue Bird and Diana Taurasi each picked up the fifth gold medals of their remarkable careers.

Jennifer Valente emerged victorious from the multi-race omnium cycling event at the Izu Velodrome, with the 26-year-old from San Diego scooping the first Olympic gold of her career.

Volleyball gold medals had previously been the preserve of the men among the US ranks, but now the women have triumphed at Olympic level too.

Their first visit to the top step of the Games podium was secured by a 3-0 win over Brazil in Sunday's final.

Haleigh Washington, a 25-year-old star of the team, said: “It's a great day to have a gold-medal day. The hard work we put in, the sweat, the tears, the blood, it’s been worth it. I am so proud to have done it with this group of women. I am so honoured."

Coach Karch Kiraly added: "I am so happy for this team and these amazing women in this programme. I told them not only are they bad-asses, but they are now gold medallists."
