Andy Murray feels claiming an Olympic medal at Tokyo 2020 would be the greatest achievement of his illustrious tennis career.

Set to take part in his fourth Games as he looks to defend the singles title he won at London 2012 and successfully retained at Rio 2016, Murray knows this tournament is likely to be his last at the Olympics.

A creditable and entertaining run to the third round of Wimbledon came amid questions over his long-term future in the game after several years of injury woe.

After losing to Denis Shapovalov at the All England Club, Murray has been drawn to play against another Canadian, Felix Auger-Aliassime, in Tokyo.

He will also play in the men’s doubles alongside Joe Salisbury, with a tough draw in that competition too against Pierre-Hugues Herbert and Nicolas Mahut.

Despite having three grand slam wins, two Olympic titles and a doubles silver medal to his name, Murray believes a podium place in Japan – which he feels is possible – would be a crowning achievement after all he has been through. 

"That is the goal, to try and win another medal," Murray told reporters. "I'm aware that it is not going to be easy. 

"I'm also in a slightly different position to what I was four, five years ago when I would’ve been expected to get one. 

"Maybe that is not the case this time around, but for me, it would probably be my best achievement if I could do that after everything that’s gone on the last few years. 

"I'm motivated for that reason alone and I still believe that I can do that. I still believe that it is possible."

Now 34, it is by no means certain Murray will still be playing and competitive on the ATP Tour by the time the 2024 Olympics take place in Paris.

"I know that this could be the last [Olympics] for me," added the Briton.

"So I want to go out there and leave everything out on the court, fight for every single point because ultimately that’s all you can do."

Having beaten Roger Federer and Juan Martin del Potro in his two Olympic finals, Murray – who revealed he has practiced well and regularly since Wimbledon - hopes his experience of going all the way at the Games will work in his favour.

He added to BBC Sport: "I've prepared as best as I can. I have tough draws in singles and doubles but I think I have a chance.

"If I can get through a round or two I'll start to feel more comfortable. I also have the experience of playing in the Olympics, which I can use to my advantage."

Ash Barty and home favourite Naomi Osaka start their respective quests for Olympic gold against Sara Sorribes Tormo and Zheng Saisai, while Novak Djokovic opens against Hugo Dellien.

In a stacked women's draw, world number one and Wimbledon champion Barty has a tough opening assignment and could face French Open finalist Anastasia Pavlyuchenkova, the 13th seed, as early as round three.

Spectators may not be in attendance at Tokyo venues for the Olympics but Japanese fans will be rooting for Osaka, who returns to action after a two-month hiatus with the four-time grand slam winner having spoken openly about mental health and anxiety issues.

Viktorija Golubic or Maria Camila Osorio Serrano would await Osaka if she can get through round one, but a dream final with Barty is no shoo-in given 15 of the world's top 20 on the WTA Tour are in action including each of the nine leading the race for the 2021 WTA Finals.

Aryna Sabalenka (3), Elina Svitolina (4), Wimbledon runner-up Karolina Pliskova (5), Iga Swiatek (6) and Garbine Muguruza are all featuring in Tokyo.

The men's side has been hit by a spate of withdrawals, with Rafael Nadal, Roger Federer and Dominic Thiem among those not playing in the Japanese capital.

The main talking point surrounds whether the all-conquering Djokovic can continue his march towards a calendar Golden Slam – a sweep of all four majors and an Olympic gold in the same year.

Any notion of a free ride for the Serbian is wide of the mark, though. His side of the draw could see him come up against Andrey Rublev (5), Alexander Zverev (4) and Hubert Hurkacz (7), while Stefano Tsitsipas (3) – beaten by Djokovic in the French Open final – and Daniil Medvedev (2) are among the potential final opponents.

Andy Murray, gold medal winner in 2012 and 2016, faces Canada's Felix Auger-Aliassime in a tricky first-round match.

Novak Djokovic has leapt from one bubble into another as he attempts to become the first man in tennis history to win all four grand slams and Olympic gold in the same year.

The only men to have won each of the singles majors across their careers, plus Olympic gold, are Andre Agassi and Rafael Nadal, and now Djokovic aims to move to the brink of winning all five in his remarkable 2021 season.

Fresh from dominating at Wimbledon, and with the Australian and French Open titles already in the bag, Djokovic heads into the Tokyo Games as a red-hot favourite, seeking to set himself up to complete a historic campaign at the US Open.

Naomi Osaka will enter the Games with almost as much expectation behind her too, the reigning US Open and Australian Open champion eyeing glory for hosts Japan.

But tennis has thrown up a host of shock results in its short Olympic history. Here, Stats Perform looks at the sport's place in the Games.

WHO'S IN, WHO'S OUT, AND WHAT DOES ALL THIS MEAN?

Serena Williams, Roger Federer and Rafael Nadal have all opted out of the Olympics.

Williams made her mind up prior to suffering a leg injury at Wimbledon, although she is already a member of the career Golden Slam club.

Federer reached his decision after revealing he also suffered a physical setback at the All England Club, and Nadal elected to take a two-month break after relinquishing his French Open title.

Don't expect to see them again at the Olympics, given Williams and Federer will be pushing 43 by Paris 2024, and Nadal will be 38. Federer won a doubles gold with Stan Wawrinka in 2008, but his singles peak was the silver medal he earned in 2012, Andy Murray crushing Swiss hopes in the final at Wimbledon.

Dominic Thiem, Bianca Andreescu, Nick Kyrgios, Simona Halep, Angelique Kerber, Victoria Azarenka and Denis Shapovalov are among other confirmed absentees, with fitness issues a factor for some, less so for others.

The COVID-19 crisis is a mitigating factor in why so many stars are staying away, and directly responsible in the case of some players, such as Britain's Johanna Konta and Dan Evans, who both tested positive recently.

But tennis was only fully restored to the Olympic programme in 1988, after being dropped post 1924, and if players are seen to be favouring the grand slams over the Games, that is not such a great look for the sport.

At a time when the International Olympic Committee has shown it is willing to shake up the sports on its programme, tennis could perhaps do with a headline-making Tokyo 2020.

Murray, the two-time defending men's champion, will target an improbable hat-trick. A hat-trick for the injury-hit former world number one would be a sensation, and Osaka landing gold in the women's tournament would surely be one of the great moments of the Games.

DJOKOVIC FOLLOWING IN THE FOOTSTEPS OF GRAF

When Steffi Graf beat Gabriela Sabatini in the women's singles final at Seoul, it completed what we know now as the calendar 'Golden Slam'. She had already won the Australian Open, French Open, Wimbledon and the US Open, and the feat of the then 19-year-old West German has yet to be repeated.

Now Djokovic is three-fifths of the way to a similar clean sweep of the majors and the Olympics, with the US Open getting under way on August 30 in New York.

He teetered on not going to Tokyo, and perhaps he is to some extent endangering his chances at Flushing Meadows by spending more time travelling and enduring bubble life, while others rest up.

But Djokovic is a fiercely proud Serbian and could not resist a great chance of winning gold for his country. He landed bronze at the 2008 Games in Beijing but in 2012 he lost to Juan Martin del Potro in the bronze-medal match, and a cruel draw at Rio four years later saw him assigned Del Potro in the first round.

Top seed Djokovic bowed out in two tie-breaks to the powerful Argentinian, describing the outcome as "one of the toughest losses in my career".

There is no danger of a hat-trick of defeats to Del Potro, which may help Djokovic. Del Potro has been battling for two years to get back to fitness, undergoing four rounds of right knee surgery in a bid to get back on tour.

RAISING THE BAR AT THE OLYMPICS

How the Olympic village functions in Tokyo will be distinctly different to at previous Games, given the pandemic restrictions in place that could be a real buzzkill.

But in the past there have been countless cases of athletes becoming inspired by their surroundings and going on to perform above their usual level.

It can be a party village, and it can also be an eyebrow-raising experience as global superstars rub shoulders with competitors who might struggle for recognition in their home towns. More than anything, the shared team experience, fighting for a collective cause, can make a middling athlete believe they can be great.

Monica Puig was a massive tennis outsider in 2016 but the then world number 34 won the women's singles, stunning Angelique Kerber in the final after beating Petra Kvitova and Garbine Muguruza en route. That gave Puerto Rico their first ever Olympic gold medal.

In 1992, a tournament that featured the likes of Pete Sampras, Jim Courier, Stefan Edberg and Boris Becker finished with a staggering final match-up of Marc Rosset versus Jordi Arrese, who in his home city of Barcelona was edged out 8-6 in the fifth set by the Swiss world number 43. Nobody would have predicted that head to head for gold.

Similarly, at Athens 2004, Nicolas Massu beat Mardy Fish in the gold medal match of a tournament that featured Federer, Andy Roddick, Carlos Moya and Tim Henman.

In the 1996 Atlanta Games, Lindsay Davenport, who had just turned 20, took inspiration from being the daughter of an Olympian, with dad Wink having played volleyball for the United States at Mexico City in 1968.

Davenport was beginning to make an impact on the WTA Tour but was only the ninth seed at the Olympics, yet she swept through the rounds before sinking Arantxa Sanchez Vicario 7-6 (10-8) 6-2 in the final.

"It's like one of those things I look back on and I'm like, 'Was that me?'," Davenport told The Tennis Podcast last year.

"It doesn't seem like it was real. I'd made the transition to the pro tour pretty well, but I liked hanging out between eight and 16 in the rankings. I was very insecure, unsure of what could I do. I liked doing well but I wasn't sure I wanted to do too well because it seemed really overwhelming to be one of those top players.

"Here I go at 20 years old to Atlanta for two or three weeks, in a setting that seemed so comfortable. Look at all these athletes, you have all different shapes and sizes, you have players that are really working hard but have so much in common and you get to hang out with them, breakfast, lunch, dinner in the village."

Davenport was a future world number one and three-time grand slam singles champion, but at this point in her career being an American at an Olympics in the United States was just a thrill.

"You're sharing this with your team-mates who are some of my best friends in Mary Joe Fernandez, Monica Seles. It was the best time ever," she said.

"By the time the tournament actually started we were like, 'Yeah, I'll go play my match and then we'll go back to the village and we'll hang out', and everything went so fast in those few weeks.

"And there I was left standing, winning at the end because I was so incredibly happy and excited with everything that was going on. I kind of forgot what was my job.

"When it became a reality of even just making the team in '96, it was so huge also for my family with having a second generation Olympian."

The sporting calendar provides many memorable days throughout the year but rarely do elite events overlap as often as at the Olympics.

At this year's delayed Tokyo Games, there is the prospect of seeing several of the world's top athletes all competing for gold at the same time.

August 1 looks a good bet for the standout day in 2021.

The final round of the men's golf event could see Rory McIlroy and Jon Rahm in the mix, with Andy Murray hopeful he will meanwhile be defending consecutive singles gold medals in the tennis.

This comes on the same day that Simone Biles could potentially become the most decorated Olympic gymnast of all time.

As if that were not enough, the men's 100m final is another must-watch event.

Expectations will be high heading into that second Sunday of the Games, with examples from the past three competitions living up to their billing...

AUGUST 16, BEIJING 2008

Michael Phelps and Usain Bolt would be firmly in contention to appear on the Games' own Mount Rushmore and each enjoyed one of the finest moments of their respective careers on the same day.

Phelps had spent the opening week of the Beijing Olympics pursuing Mark Spitz's 1972 record of seven golds and had six as he entered the pool again for the 100m butterfly final, almost 12 hours before Bolt's big moment.

Seventh at the turn, the United States superstar needed a remarkable recovery to triumph over a devastated Milorad Cavic by 0.01 seconds.

Phelps would pass Spitz with his eighth gold of the Games the following day, by which point he was sharing the headlines with Jamaica's own ultimate athlete.

Bolt's blistering 9.69-second final triumph in the 100m stood as a world record until the same man beat it exactly a year later. The new benchmark remains unmatched.

And that Saturday in China also saw the small matter of Roger Federer's only gold medal, claimed alongside Stan Wawrinka in the doubles final after falling to James Blake as the top seed in the singles.

AUGUST 4-5, LONDON 2012

It is actually tough to choose just one day from the 2012 Olympics, where this weekend delivered from start to finish.

On the Saturday evening, at the Aquatics Centre, swimming prepared to say goodbye to its greatest name. Phelps and the United States won the 4x100m medley, clinching his 18th gold medal in what appeared set to be his final race.

Indeed, Phelps confirmed his retirement following the Games, only to return in predictably dominant fashion in 2016.

Across the city that same night, Team GB athletes were capping a stunning run of medals that would see the day dubbed "Super Saturday". There were six home golds in all, including big wins for Jessica Ennis, Greg Rutherford and Mo Farah in quick succession.

The drama only continued the next day, too, as Murray finally sealed a Wimbledon win over Roger Federer in the tennis event, while Bolt lit up London Stadium in the 100m.

AUGUST 14, RIO 2016

Although there will be no Bolt brilliance in Tokyo, Brazil was treated to another show as he became the first three-time winner of the 100m – later doing likewise in the 200m.

The first triumph was almost overshadowed on the track, however, coming shortly after Wayde van Niekerk had broken Michael Johnson's 17-year 400m world record by 0.15 seconds.

Again, the excitement was not reserved for athletics, with Murray in action that evening to claim another gold after coming through a four-hour epic against Juan Martin del Potro.

Murray is the only player – men's or women's – to win consecutive singles golds, while Rafael Nadal's presence added a little more stardust even though he lost the bronze final to Kei Nishikori.

A stunning Sunday also saw Biles add to the reputation she takes with her to Tokyo, a third gold on the vault making her the most decorated American gymnast.

And there was history, too, for Justin Rose, as he edged past Henrik Stenson at the 18th hole of the fourth round to become the first Olympic golf champion in 112 years.

Andy Murray raised doubts over his future after losing in the third round at Wimbledon, leaving the grand slam with one question: "Is it worth it?".

Murray's Wimbledon journey came to an end on Friday following the former world number one's 6-4 6-2 6-2 loss to 10th seed Denis Shapovalov on Centre Court.

Making his first appearance in the main draw since he was the defending champion at Wimbledon in 2017, Murray's career has been devastated by injuries.

Murray underwent hip resurfacing in 2019 but the three-time grand slam champion has continued to be plagued by fitness problems.

After suffering his earliest Wimbledon exit since 2005, Murray was in a downbeat mood as he was left to ponder his next move.

"It was great playing in front of the crowds again," the 34-year-old said. "I got amazing support here. I'm very thankful for that. Something I have missed. It kind of reminds you why you do all of the work and everything.

"But then, on the flip side of that, the positive part is getting through the matches and feeling OK physically and not getting injured.

"That's good but then there is a part of me that feels a bit like I have put in so much work the last three months and ultimately didn't play how I would want and expect, and it’s like, is it worth it?

"Is all of that training and everything that you're doing in the gym, unless you're able to practise and improve your game and get matches and get a run of tournaments, is it worth all of the work that you're doing?

"There is part of me that feels like, yes, it is, because I had great memories and stuff from this event and playing in some brilliant atmospheres. But I finished the match tonight and I'm saying to my team, 'I'm just not happy with how I played'.

"So, unless me and my team can find a way of keeping me on the court for a consistent period of time and allow me to practise the way that I need to to compete with these guys, that's when the discussions about what I do next will come in.

"Because I have genuinely put a lot into this to get to this point, but I'm not being able to practise and prepare how I need to to perform how I would like at these events.

"I’m not expecting and saying I would beat Denis Shapovalov. He's a brilliant player. But I feel like I can do a lot better than what I did this evening."

Andy Murray's Wimbledon adventure is over – for this year at least – after Denis Shapovalov put an end to his challenge in a one-sided Centre Court clash.

The doughty two-time former champion insists retirement is not at the forefront of his mind, but a 6-4 6-2 6-2 loss to 10th seed Shapovalov was a fresh reminder of his current place in the tennis pecking order.

After hip resurfacing surgery gave Murray another shot at the career that at one stage looked all but over, it was a Wimbledon return which was high on his list of priorities.

This was Murray's first appearance in the singles since 2017, the year he was last defending champion.

Earlier this year the former world number one spoke of a belief that he could win the tournament for a third time, but he will be 35 by the time next year's championships come around and many have doubts about whether he will still be playing. He came into this fortnight at 118th in the rankings.

Not even the closure of the Centre Court roof could save Murray this time. That had been the spur, coincidentally or not, for his two previous late-night matches to swing around in the Scot's favour, as he saw off Nikoloz Basilashvili and then the unheralded German Oscar Otte to reach this last-32 stage.

Murray and Shapovalov went off after the second set of this contest, as evening turned to night in south-west London and the lights came on, but Murray did not return with super-human strengths this time, and his opponent raced to victory.

Shapovalov told Murray at the net that the Scot was his hero, and spoke eloquently about his appreciation of his comeback, and perhaps Murray would have quietly admired the Canadian's skill in moving in for the kill.

This match had been all one way for much of the first set too, but then Murray found a spark and pulled back from 5-1 adrift to 5-4, the crowd beginning to believe it could be his day again.

Murray believed too, of course, but this match proved a step too far for the champion of 2013 and 2016. There were flickers of Murray at his best, and he will represent Great Britain at the upcoming Olympics, where he is a two-time defending champion, but Murray's days of being a grand slam contender are, on the balance of probabilities, pretty much over.

His career has been a spectacular affair, and there was a familiar ovation as he departed Centre Court.

Shapovalov had rammed down an ace on match point, clinical in his despatching of the crowd's favourite.

Speaking at the end of the match, Shapovalov said in an on-court interview: "This is a dream come true for me.

"I've put countless years of hard work into every practice so that one day maybe I could play on Centre Court – to play against a legend like Andy today, to play a match like this. First of all, huge shout-outs to him. What he is doing nobody has ever done. He's truly an inspiration to many people, including me.

"I just told him at the net that he's my hero. Achievements aside, what he's been able to do in the sport with an injury like this and to play the tennis he's playing and moving the way he's moving.

"In his second match it was like vintage Andy and it was just so much fun to see as a fan. I was really excited and the first set today was super, super intense.

"It's incredible what he's done to make it to the third round like this and he's just starting back up so it's going to be amazing to see what he can do."

Andy Murray reveled in a raucous Centre Court atmosphere after he fought back to keep himself in Wimbledon contention.

Murray had to defy the odds once more to overcome qualifier Oscar Otte 6-3 4-6 4-6 6-4 6-2 in a thrilling contest which lasted almost four hours.

Having led by a set and a break, Murray squandered his advantage to Wimbledon debutant Otte, who capitalised on the Scot's slip ups to take a 2-1 lead by the time bad light forced the players off.

But the break did Murray the world of good, with the former world number one winning seven of the next nine games with the full backing of a thoroughly one-sided crowd under the closed roof.

The 34-year-old was leaping in joy and punching the air when he held off Otte to hold serve and take a 5-2 lead in the deciding set, before he sealed the win with a deft lob shot to prove he still has the quality to go with his spirit.

"I enjoyed the end! The middle part, not so much! What an atmosphere to play in at the end. The whole crowd was amazing but there was a few guys in there getting me fired up," a thrilled, yet drained, Murray told BBC Sport. 

"I needed everyone's help tonight, they did a great job. I hit some great shots at the end to finish it but it was a tough match."

Murray's battle with Otte came just two days after a similarly tough contest against Nikoloz Basilashvili, and despite starting Wednesday's second-round tie well, the two-time Wimbledon champion knows he almost let the match slip away.

"I had to do something differently and started going for my shots more, dictating more of my points, I was being a little bit negative," Murray said when asked if the break in play helped him recover.

"Because of the lack of matches, in the important moments I didn't make the right decision a lot of the time but I think I played the right way in the last couple of sets. The first set and a half was really good but there was just bits in the middle I'd like to change.

"Obviously tired, I fell over a couple of times, they're pretty slick courts but considering everything I feel all right, hips feel pretty good, I get a rest day tomorrow and hopefully will come out on Friday and play in another atmosphere like this and perform well."

Murray has already accumulated over seven hours of time on court over his first two matches, and he now faces 10th seed Denis Shapovalov, who was handed a walkover on Wednesday due to Pablo Andujar's rib injury.

Andy Murray made clear he is far from finished after overcoming a fourth-set wobble to upset 24th seed Nikoloz Basilashvili in the first round at Wimbledon.

The two-time champion at SW19 has seen his career beset by injury issues in recent years, with this his first appearance in the main draw since reaching the quarter-finals in 2017.

However, he won two matches at Queen’s Club ahead of the third grand slam of the season and treated the Centre Court crowd to a trip down memory lane on Monday, including a dramatic twist when seemingly on the brink of victory.

Having taken the first two sets, Murray somehow contrived to lose the third despite at one stage holding a 5-0 lead. The sudden collapse sent nerves jangling among the spectators as the roof was closed at the venue, but he responded impressively to the setback to triumph 6-4 6-3 5-7 6-3.

Speaking during his on-court interview after the triumph, the Scotsman once again reiterated he has no plans to make this year his Wimbledon swansong.

"It's been extremely tough. Even these last few months. It has been extremely frustrating not being able to get on the court," Murray said.

"I've had such little momentum over these last few years. I've kept trying, doing all the right things to be back in this position. I feel very lucky I get to do it again.

"I keep getting asked is this going to be my last Wimbledon. I don't know why I keep getting asked, though. No, I'm going to keep on playing.

"I want to play, I'm enjoying it. I can still play at the highest level. He is ranked 28th in the world and I beat him, so I will keep going."

Basilashvili saved two match points as he somehow survived in the third set by winning seven games in a row, though Murray responded to the setback impressively.

"I did well to win the fourth set in the end because that was mentally not easy going to the locker room after losing that third," Murray added.

Next up will be either Oscar Otte or Arthur Rinderknech, their contest having been locked at 9-9 in the deciding set when play on the opening day was suspended on the outside courts.

Andy Murray plays his first Wimbledon singles match in four years on Monday – with the journey back to Centre Court hailed as an equivalent achievement to his grand slam titles.

The former world number one has battled through injuries that threatened to end his career, so it will be a remarkable feat when he walks out to face Nikoloz Basilashvili.

Murray, who has won Wimbledon twice and the US Open once, as well as landing two Olympic gold medals in singles, underwent hip resurfacing in 2019 but has continued to be plagued by fitness problems.

The tribute to the resilience of the 34-year-old came from women's British number one Johanna Konta, who was cruelly ruled out of Wimbledon on Sunday when a close contact tested positive for COVID-19.

Konta, who spoke to Stats Perform before receiving that painful news, reached the Wimbledon semi-finals in 2017, the last year Murray played singles at the All England Club.

He was fit enough to play doubles in 2019, partnering Serena Williams in the mixed event, but a billing on the main show court promises to be an emotional occasion for a player who is struggling to repeat past glories.

"I think Andy really represents tenacity and perseverance," said Konta, a Jaguar ambassador.

"He loves this game, he loves winning in this game, he loves being good and great in this game. I think he will keep doing everything he can to keep putting himself back into position to be great."

"I think maybe bringing the attention more on the fact he is trying to do that, with the challenges he's had, is what we should be celebrating and we should be really acknowledging.

"I think this is probably equally as difficult as when he won his slams and his gold medals.

"I think it's on a par with that achievement. I think and hope people can see that and really acknowledge it because he really deserves that."

After an enforced hiatus in 2020 due to the coronavirus pandemic, tennis returns to SW19.

Novak Djokovic makes his way back to Wimbledon as the defending champion and with the men's grand slam record firmly in his sight.

Djokovic conquered Rafael Nadal en route to French Open glory and his 19th slam crown – one shy of the record shared by rivals Nadal and Roger Federer.

With Nadal and Dominic Thiem absent, Djokovic's path to a 20th major trophy has opened up in London.

The women's title is up for grabs after holder Simona Halep withdrew, and Serena Williams can still dream of making history.

As all eyes shift to the All England Club, Stats Perform looks at the numbers behind this year's slam, using Opta data.

Dominant Djokovic

World number one and top seed Djokovic begins his title defence against promising Briton Jack Draper in the first round.

French Open champion Djokovic has won four of the last six Wimbledon tournaments, including each of the past two – the last player to win more at Wimbledon in a row was Federer between 2003 and 2007 (five).

A five-time Wimbledon winner, Djokovic is the only man to have won the first two grand slam tournaments of a calendar year over the last 25 years, doing it in 2016 and 2021. The last man to win the first three grand slams of a calendar year was Rod Laver during his Grand Slam in 1969.

The 2019 Wimbledon final was the first slam decider to be decided by a final set tie-break, with Djokovic beating Federer 7-3 in that tiebreak, while it was also the longest final in Wimbledon history (four hours, 57 minutes).

No man has won Roland Garros and Wimbledon in the same year since Nadal in 2010.

Federer farewell?

The curtain appears to be closing on all-time great Federer, who withdrew from the French Open after a draining four-set win over Dominik Koepfer to preserve his body for the grass season.

This year's Wimbledon could be the 39-year-old's final realistic shot at a grand slam as Djokovic bids to become the greatest of all.

Seeded sixth, Federer – who meets Adrian Mannarino first up – has won the most Wimbledon titles among all male players in the slam's history.

Federer will aim to win his 21st grand slam, which would break a tie with Nadal for the outright men's record.

The 'Big Four' and their stranglehold

Injuries have forced two-time Wimbledon champion Andy Murray to fall out of the equation but there has been no getting past the original 'Big Four'.

Among the men, the last 17 years of Wimbledon has been dominated by the same four players – Federer (eight titles), Djokovic (five), Nadal (two), Murray (two). The last winner at Wimbledon before them was Lleyton Hewitt in 2002.

Since Wimbledon in 2004, only one of the 68 slams has not seen at least one of Federer, Djokovic and Nadal in the semi-finals – it was at the US Open last year.

The new generation is headlined by grand slam runners-up Daniil Medvedev and Stefanos Tsitsipas.

Medvedev has never passed the third round at Wimbledon, though his two defeats at that stage have both been in five sets. The Russian second seed has reached at least the quarter-finals in three of his last four major tournaments, after reaching that stage in only one of his previous 13.

Beaten by Djokovic in the Roland Garros final, Tsitsipas has reached the semi-finals in his last three slams, having done so only once in his previous 12. The third seed has never reached the quarter-finals at Wimbledon, however.

Wimbledon is the only slam where fourth seed Alexander Zverev is yet to reach the quarter-final, his best result being a fourth-round performance in 2017. Since the beginning of 2020, he has advanced to the semi-finals in three slam tournaments, after never doing it in his previous 18 such major main-draw appearances.

Serena's ongoing quest

The queen of WTA tennis for so long, Serena Williams is one slam success away from matching Margaret Court's record of 24 major singles championships. But the 39-year-old has been stuck on 23 since reigning supreme at the Australian Open in 2017.

Williams, who lost in the French Open fourth round, has won seven Wimbledon titles (level with Steffi Graf) – only Martina Navratilova has more in the Open Era (nine).

American superstar Williams has been a Wimbledon runner-up in 2018 and 2019. Chris Evert is the only player in the Open Era to have lost three consecutive Wimbledon finals (between 1978 and 1980).

Williams, the sixth seed who will clash with Aliaksandra Sasnovich in the opening round, is looking to become only the second woman to win 100 Wimbledon singles matches (currently 98), alongside Navratilova (120). She could also become the first woman to reach 100-plus wins in two different majors (106 wins at the US Open).

From the first Wimbledon final reached by one Williams sister in 2000 (won by Venus against Lindsay Davenport), only in four of 20 editions has neither of the two sisters reached the decider – in 2006 (Amelie Mauresmo-Justine Henin), 2011 (Petra Kvitova-Maria Sharapova), 2013 (Marion Bartoli-Sabine Lisicki) and 2014 (Kvitova-Eugenie Bouchard).

Barty party?

Former French Open champion Ash Barty heads to Wimbledon as the top seed and will kick off her title bid against veteran Carla Suarez Navarro.

However, world number one Barty has never reached the Wimbledon quarter-finals. Reaching the 2019 fourth round was her best result. The last Australian woman to reach the quarters at Wimbledon was Jelena Dokic in 2000.

The top seed in the Wimbledon women's singles main draw has been eliminated in the first round just three times in the Open Era – Graf in 1994, Martina Hingis in 1999 and Hingis again in 2001.

Wimbledon is the only major won by Kvitova in her career (2011 and 2014). She is one among the three current players with multiple titles at the All England Club, alongside Serena and Venus Williams.

Karolina Pliskova was the woman with the most aces per match made on average at Wimbledon 2019 (9.0, 36 in total) among players who reached the third round.

Novak Djokovic will start the defence of his Wimbledon title against British wildcard Jack Draper, and Serena Williams takes on Aliaksandra Sasnovich in the first round.

Djokovic is just one grand slam title away from matching Roger Federer and Rafael Nadal's record tally of 20 after winning the Australian Open and French Open this year.

The world number one will take on 19-year-old Draper, a quarter-finalist at Queen's Club last week, in his first match at SW19 for two years after the 2020 championships were called off due to the coronavirus pandemic.

Djokovic faces a potential quarter-final against Andrey Rublev, while Federer could come up against second seed Daniil Medvedev in last eight.

First up for eight-time Wimbledon champion Federer is an encounter with Adrian Mannarino, while injury-plagued two-time winner Andy Murray will start his home major against the 24th seed Nikoloz Basilashvili.

Stefanos Tsitsipas, beaten by Djokovic in a thrilling French Open final this month, has been drawn to face American Frances Tiafoe in round one of a tournament that gets under way on Monday.

Simona Halep announced just before the draw was made on Friday that she would not defend her title due to a calf injury.

Williams, runner-up to Halep in the 2019 final, must get past Sasnovich of Belarus in the first round and could face third seed Elina Svitolina at the quarter-final stage.

World number one and top seed Ash Barty takes on Carla Suarez Navarro, who made a grand slam return at Roland Garros after recovering from cancer. Barty could come up against Bianca Andreescu in the last eight.

Petra Kvitova against Sloane Stephens is a standout first-round match, while Coco Gauff's first assignment will be a meeting with 20-year-old Briton Fran Jones.

Andy Murray has been selected as part of six-strong Great Britain tennis squad for the upcoming Olympic Games.

The Scot, a two-time winner in men's singles and the current champion, will have another opportunity to strike gold when he competes in Tokyo.

Murray is set to appear at his fourth Olympics having also been part of the squad for Beijing 2008 prior to victories at London 2012 and Rio 2016.

On his inclusion, he said: "The Olympics means a huge amount to me, it’s a massive honour to be able to compete at a fourth Games. 

"Leading Team GB out at the Opening Ceremony five years ago in Rio was one of the highlights of my career. 

"Going to a second Olympics as defending champion is exciting and I’m looking forward to the challenge."

Murray will also compete in the men's doubles alongside Joe Salisbury, an Olympic debutant and two-time Grand Slam doubles winner - most recently in the French Open mixed event.

Current GB number one Dan Evans is also part of the men's line-up, and is set to compete in both the singles and doubles events this summer.

His partner in the latter will be two-time Grand Slam doubles semi-finalist Neal Skupski who, like Evans, is set to appear at his first Games.

GB's women's representatives are Heather Watson and Johanna Konta, who are appearing at their third and second Olympic Games respectively.

Both players will compete in the women's singles event and team up for the doubles.

Team GB chef de mission Mark England said: “It’s a huge privilege to announce our tennis players for Team GB. 

"The calibre of the team gets stronger with every Games and it is great to see a mix of returning and first time Olympians. 

"Two-time Olympic Champion Andy Murray was our flag bearer in Rio and he continues to lead by example through his commitment to the Olympic Games and Team GB in what will be his fourth Olympics. 

"We are also delighted to welcome back Heather and Johanna as returning Olympians, and I am sure they will all pass on the best of their insight to Dan, Joe and Neal."

Andy Murray is hopeful 2021 will prove not to be his last appearance at Wimbledon.

The two-time tournament winner has been handed a wildcard for the grass-court grand slam in London, which was cancelled last year due to the coronavirus pandemic.

Murray also missed the 2018 and 2019 tournaments due to injury, so this year will be his first Wimbledon outing since reaching the quarter-finals in 2017, when the ailing Briton suffered a five-set defeat to Sam Querrey.

Ahead of his first Wimbledon appearance in four years, the 34-year-old hopes to play in many more, though he will savour the experience and take nothing for granted given his recent injury woe.

"To me it's not so much about me worrying about it being my last one, it's just something that I think about," Murray told Sky News.

"I don't want it to be my last Wimbledon, certainly I want to keep playing, I don't want to stop just now, so yeah I want to keep going.

"I've had so many injuries and so many setbacks you just don't really know what's round the corner.

"I want to approach each tournament and each match that I play like it's my last one so that I can get the most out of it.

"So that's why I want to prepare here well. I'm going into the bubble on Wednesday evening so I'm going to get there early to practise at Wimbledon. 

"Hopefully I've got some high quality practices – I'm practising with Marin Cilic and I practise with Roger Federer later in the week.

"I'm just trying to play with high quality grass court players to prepare me as best as possible." 

Murray, who has undergone two hip surgeries since he last played at Wimbledon, earned an impressive win on the grass over Benoit Paire at Queen's last week.

He then lost in straight sets to eventual champion Matteo Berrettini in round two.

As long as he can prepare properly and remain competitive, three-time grand slam champion Murray, who has also previously won the US Open, wants to battle on.

He added: "It's more about the body if I'm restricted in how I can prepare. 

"If I can't prepare properly to compete then that's when it's not fair on yourself to keep putting yourself out there, because you're not properly prepared and can't do yourself justice.

"So if that was the case and I was having to compromise on my training just to get out there on a match court and my results weren't good – that is something I'd look at. 

"But providing I can train and prepare well and I'm enjoying it I'll do it for as long as I can."

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.

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.
