Olympics chief Thomas Bach revealed he masked his concerns about Tokyo 2020 going ahead because of fears the Games might "fall to pieces".

Bach is president of the International Olympic Committee, which he said "had to show a way out of this crisis" in order for the global event to go ahead amid the COVID-19 pandemic.

Speaking on Tuesday in Tokyo, Bach said the IOC had experienced daily concerns about the Olympics being able to proceed but had to present a positive message to stakeholders including sporting federations, sponsors, the Japanese government and broadcasters.

Had the IOC been open about worries for the Games, which were delayed by a year due to the global health crisis, Bach said it could have triggered a chain of events that would have seen the Olympics collapse.

Instead, the Games get under way this week, with the opening ceremony due to take place on Friday.

Bach said: "Over the past 15 months, we had to take daily decisions on very uncertain grounds. We had doubts every day. We deliberated and we discussed. There were sleepless nights. Like everyone else in the world, we did not know, I did not know, what the future would hold."

Bach appeared to scoff at any suggestion of the IOC deciding to "blindly force ahead at any price" and spoke of the "extreme stress test of the coronavirus crisis".

"Imagine for a moment what it would have meant if the leader of the Olympic movement, the IOC, would have added to the already many doubts surrounding the Olympic Games, if we would have poured fuel onto this fire," Bach said.

"How could we have convinced the athletes to continue to prepare for the Olympic Games by adding to their uncertainty?

"How could we have convinced all the other stakeholders to remain committed to the Olympic Games if we would have even deepened their already serious doubts.

"Our doubts could have become a self-fulfilling prophecy. The Olympic Games could have fallen to pieces. This is why, we had to keep these doubts to ourselves. This today I can admit and say it, it also weighed on us, it weighed on me.

"But in order to arrive at this day today, we had to give confidence. We had to show a way out of this crisis. We had to provide stability. We had to build trust. We had to give hope."

The IOC announced updated COVID-19 case figures for the Games on Tuesday, with 40 confirmed cases involving residents of Japan and 31 affecting those from overseas.

Having seen crowds return to a range of tour events, former Wimbledon winner Pat Cash understands the disappointment of tennis moving back to behind closed doors at the Olympic Games in Tokyo.

Each of the three grand slam events to have taken place this year has been held with fans in attendance, with Centre Court seeing capacity crowds for each of the singles finals at Wimbledon. The US Open, which begins on August 30, will allow 100 per cent fan capacity at Flushing Meadows for the final major of 2021.

However, Cash does not believe the lack of spectators at the Games will have too much of an impact on the players who have elected to travel to Japan.

"Well it's unfortunate that the Olympics won't have any fans. I think that's a real disappointment," Cash told Stats Perform.

"But 95 per cent of our life is played on an empty practice court and stadiums.

"Certainly, when you're coming through, nobody's watching you. It's only when you get to Wimbledon or something that you play with crowds, and they can make a difference. We've also been playing most of the year without them.

"To go back [to no fans] it's unfortunate, but it's not something unusual for the players. The crowd certainly does make a difference. It makes a difference with attention and with the crowd roaring and whistling or whatever they want to do."

World number two Naomi Osaka, who will return to action having withdrawn from the French Open to protect her well-being and subsequently skipped Wimbledon, is one athlete who could have benefited from the home support in Japan.

Though he is unsure of how boisterous the home crowd would have been in Tokyo, Cash still feels for the 23-year-old four-time Grand Slam winner.

"With no crowds there that's disappointing for her," he added. 

"But you know, it's sort of something we've become used to on the tour - playing with empty crowds and the nerves still kick in, it is all about winning, and players tend to learn to block the crowds out quite well.

"They stay in their own world when they're on the tennis court. The urgency and the intensity of a match is not really going to change that much because the players really want this for themselves."

A female United States gymnast has tested positive for coronavirus while training in Tokyo ahead of the Olympics, the US Olympic Committee (USOC) has confirmed.

The unnamed athlete was an alternate – a team member included as a reserve – and will now isolate along with another team member who has been identified as a close contact.

"The health and safety of our athletes, coaches and staff is our top priority," a USOC statement read.

"We can confirm that an alternate on the women's artistic gymnastics team tested positive for COVID-19.

"Out of respect for the individual's privacy, we cannot provide more information at this time."

The positive test comes just four days before the delayed Games begins, with fellow US female gymnast Simone Biles set to be one of the stars of the competition.

The 24-year-old won four gold medals and a bronze at Rio 2016 and will be looking to add to that haul when the women's gymnastics competition starts on July 25.

It was also confirmed on Monday that Czech Republic beach volleyball player Ondrej Perusic tested positive for COVID-19.

Perusic and playing partner David Schweiner are due to begin their Tokyo 2020 campaign against Latvia on July 26, but the Czech Olympic Committee will seek to postpone the game until Perusic is cleared to play.

The number of Games-linked individuals to have tested positive for coronavirus since testing began on July 1 stood at 60 on Monday.

South Africa's men's football pair Thabiso Monyane and Kamohelo Mahlatsi were the first two athletes inside the Olympic Village to test positive over the weekend.

Around 11,000 athletes from 205 national Olympic committees are expected to stay at the village over the next three weeks.

The 2020 Games, delayed by a year due to the global health pandemic, will be held mostly without spectators due to a state of emergency being declared in Tokyo.

Infection rates in the Japanese capital have topped 1,000 for five days running, with a seven-day average of 1,068 as of Sunday.

Wimbledon champion Ash Barty has "a great chance" of securing Olympic glory for Australia in Tokyo.

That is the view of former Wimbledon winner Pat Cash, though he warned there is plenty of scope for upsets in both the men's and women's singles.

Monica Puig claimed a surprise victory at Rio 2016 - then ranked 34th, she stunned Angelique Kerber in the final after beating Petra Kvitova and Garbine Muguruza en route to give Puerto Rico their first-ever gold medal.

Roger Federer and Novak Djokovic are two greats on the men's side who have not tasted Olympic glory, something the Serbian will look to put right this year as he pursues a Golden Slam.

Cash, though, would not be surprised to see the Olympics throw up another surprise result, even though he hopes to see compatriot Barty come out on top in the women's tournament.

He told Stats Perform: "The women's draw is very, very even. If you don't play well in one of those matches, you're out. 

"There's no such thing as an easy first round really in a tournament such as the Olympics, particularly the men’s side where it's best of three sets. So if you slip up, you're gone. 

"There's no chance of coming back from two sets to one down, because it's over. So that's trickier for somebody like Djokovic who can typically run people into the ground.

"Ash has got a great chance of winning the Olympics, but I think probably there's 30 girls who think they can do that as well and they're probably right. 

"We've seen some unusual results in the Olympics and shorter form tournaments like that, also on the men's side.

"It's very hard to say, but obviously, [Barty] is in great form and full of confidence - that goes a long way to winning a gold medal."

There have been a host of high-profile withdrawals from the tennis in Tokyo.

Rafael Nadal, Federer, Dominic Thiem, Matteo Berrettini, Serena Williams, Sofia Kenin, Simona Halep and Coco Gauff among a large list of top players who will be missing.

Some absences were unavoidable due to injuries or positive coronavirus cases but some players have opted to rest amid a hectic calendar, avoiding Japan's strict COVID-19 rules in the process.

Cash has mixed views on the subject but does feel playing at the Olympics should be seen as a rare and valuable opportunity.

"I think I think they would [look back fondly at winning a medal]," said Cash.

"It’s certainly one of the regrets in my career that I didn't play the Olympics [in 1988]. I had a niggling injury and decided to rest. 

"Looking back, I thought I could have won a medal, maybe even a gold medal. I would have probably given it a really good shot. 

"In my era it wasn't the pinnacle. I think Novak Djokovic has talked about that now, he said, ‘The main thing for me is winning slams, they're the pinnacle of our game’. 

"But to win a gold medal, it's pretty cool. You'll find that the players who do win a gold medal, if you tell the grandkids, 'I won a Wimbledon trophy' or 'I won a gold medal', they’ll go, 'Oh, where’s the gold medal?'

"Having said that, there's a lot of players who aren't playing the Olympics this year. Certainly for a few years, it was a novelty - I'm not sure if it's wearing off or not. 

"But to perform for your country, I think is an honour and we haven't had the opportunity to do that much in the last couple of years. 

"With the Davis Cup, the men's competition is really just a fading, unfortunately, dying competition, which not many people really care about any more.

"That's very, very sad, so the Olympics is often the best opportunity to represent your country."

Cash delved deeper into the dilemma players are likely to have faced.

"I wouldn't put any criticism on anybody for the personal choice after these last 18 months," he said. "It's their choice, everybody's got a different journey in this and it's part of their careers. 

"With COVID and all that sort of stuff that's going on - the bubbles - some of the stresses are unknown like being away from family and friends for months on end and not actually have any break. 

"Everybody's got their own different stories, some of them are injured, some were coming back from injury, some think 'I'm not going to make a trip to Japan' - with all the restrictions it's not going be fun. 

"It's not going to be a fun Games where you can go there and watch the other athletes. In Los Angeles [the 1984 Games] the highlight was actually to go and watch the track events, which I did.

"That's not going to happen, you're in a hotel, you're in the village or, you're gonna go straight to the tennis and back only to a certain area of the village, I think it's going to be locked down for tennis players only. 

"You may not be able to mingle with the other athletes. So I think a lot of the fun has been taken out of this. 

"But again, it's representing your country and trying to get trying to get a gold medal. So some players will go to great lengths to do that."

Naomi Osaka is less likely to claim Olympics glory on home soil in Tokyo because her lack of match practice will be a disadvantage, according to Pat Cash.

Japan's Osaka has not played since withdrawing from the French Open after one match at the end of May, having revealed she would skip press conferences as "people have no regard for athletes' mental health".

Prior to taking a break from the sport, four-time grand slam champion Osaka revealed she had suffered "long bouts of depression" since winning the US Open in 2018.

The 23-year-old said this month she wants "some level of privacy and empathy" from the media when she returns to action and but also discussed her excitement at playing in a "dream" Olympics.

Former Wimbledon champion Cash insists Osaka has the game to triumph but feels it is a tougher task now given her main opponents are coming off two grand slams in quick succession.

"Yeah, she said [she was taking] time out – it's hard to know if she's going to be match hardened," Cash said to Stats Perform.

"I think that's the thing about playing Wimbledon, the grass court season. Are you match toughened? 

"That goes a huge, huge way [to achieving success, and not having that] is putting yourself under pressure and especially under those circumstances if it's for a gold medal."

Cash feels the quality and depth of opposition in the women's draw is another obstacle in Osaka's bid for gold.

Wimbledon winner Ash Barty, beaten finalist Karolina Pliskova, former French Open champion Iga Swiatek and Aryna Sabalenka are scheduled to be among the highest-ranked competitors for Osaka at the Olympics.

Cash added: "There are a lot of good players too. Going back onto the hard court, I think that favours certain players who hit the ball hard like Sabalenka for instance.

"But there's 30 girls who really do think they can win a gold medal there and I think that's true. 

"So it's very hard to predict who will win, obviously Japan want Osaka to win, but with her being out, I think it's less likely than in a normal circumstance where she's playing matches. 

"But she's such a talent that she really could come out there and blast players away, so I wouldn't put it past her."

Eight members of Great Britain's Tokyo Olympics athletics team are self-isolating after coming into close contact with an individual who tested positive for COVID-19.

The six athletes and two staff members, who each tested negative for coronavirus before flying to Japan last week, are now under the supervision of Team GB's medical team.

The individual who tested positive for coronavirus is not from the British delegation.

Team GB chef de mission, Mark England, said: "This is disappointing news for the athletes and staff, but we absolutely respect the protocols in place.

"We will offer them every support during this period and we are hopeful that they will be able resume training again soon."

The number of Games-linked individuals to have tested positive for coronavirus since testing began on July 1 now stands at 58 as of Monday, a rise of three from Sunday's update.

The latest three individuals to have tested positive – a Games-concerned personnel, a Tokyo 2020 contractor and a member of the media – will isolate for 14 days in hotel rooms.

No further athletes contracting the illness will be considered good news for officials after three individuals tested positive in the athletes' village over the weekend.

Two of those were confirmed on Sunday to be Thabiso Monyane and Kamohelo Mahlatsi of the South Africa men's football team, with the other being the team's video analyst.

Twenty-one South African players and officials have been identified as close contacts of the pair and must also isolate to stop the virus spreading in the Olympic Village.

Around 11,000 athletes from 205 national Olympic committees are expected to stay at the village over the next three weeks.

The 2020 Games, delayed by a year due to the global health pandemic, officially begins on Friday and will be held mostly without spectators due to a state of emergency being declared in Tokyo.

Infection rates in the Japanese capital have topped 1,000 for five days running, with a seven-day average of 1,068 as of Sunday.

Coco Gauff has tested positive for COVID-19 and must miss the Olympic Games in Tokyo, the American tennis prodigy announced on Sunday.

Gauff, who reached the last-16 stage at Wimbledon before losing to Angelique Kerber, has passed the $1million mark for prize-money in a season for the first time this year, rising to 25th in the WTA rankings.

The 17-year-old has a win-loss record of 31-12 for the campaign so far, and won the Emilia-Romagna Open title on clay in May.

She announced her news on social media, writing: "I am so disappointed to share the news that I have tested positive for COVID and won't be able to play in the Olympic Games in Tokyo.

"It has always been a dream of mine to represent the USA at the Olympics, and I hope there will be many more chances for me to make this come true in the future. I want to wish TEAM USA best of luck and a safe Games for every Olympian and the entire Olympic family."

The United States Tennis Association said it was "saddened" by the news, adding: "The entire USA Tennis Olympic contingent is heartbroken for Coco.

"We wish her the best as she deals with this unfortunate situation and hope to see her back on the courts very soon. We know Coco will join all of us in rooting on the other Team USA members who will be travelling to Japan and competing in the coming days."

Gauff joins a host of star names from tennis who have been ruled out, or have ruled themselves out, of the trip to Tokyo.

Serena Williams decided she would not play even before suffering a leg injury at Wimbledon, while Simona Halep, Sofia Kenin, Victoria Azarenka, Bianca Andreescu and Kerber are among other major absentees from the women's draw.

Italy's Matteo Berrettini has become the latest high-profile tennis player to pull out of the Tokyo Olympics after injuring his thigh.

The world number eight, who had a bandaged leg in last week's Wimbledon final loss to Novak Djokovic, joins Rafael Nadal, Roger Federer and Stan Wawrinka in withdrawing from the men's event.

Serena Williams, Simona Halep, Victoria Azarenka, Johanna Konta, Bianca Andreescu and Angelique Kerber are among those to have already announced their decision to skip the women's tournament in Tokyo.

Berrettini, the first Italian to reach a Wimbledon singles final, announced his decision in an Instagram post on Sunday.

The 25-year-old's announcement comes a day after compatriot Francesco Molinari revealed he will not be taking part in the golf event at the Olympics.

"I am extremely disappointed to announce my withdrawal from the Tokyo Olympic Games," Berrettini said.

"I had an MRI scan yesterday on the thigh injury I sustained during Wimbledon and was informed I will not be able to compete for a couple of weeks."

The Olympic tennis events begin on July 24 and run through to August 1.

However, the deadline to name new athletes passed on Friday, so the Italian National Olympic Committee will not be able to name a replacement to join Fabio Fognini, Lorenzo Sonego and Lorenzo Musetti.

"Representing Italy is the biggest honour for me so it is devastating to miss the Olympics," Berrettini added.

"I wish the entire Italian team the best of luck in Tokyo. I will be supporting you all the way."

Despite the flurry of withdrawals, world number one Djokovic confirmed this week that he will enter the Olympic Games.

Djokovic travels to Japan in pursuit of a ground-breaking achievement, the Serbian just two titles – the Olympics and US Open – away from a first men's Golden Slam after triumphing at the Australian Open, French Open and Wimbledon in 2021

The first two athletes to test positive for coronavirus in Tokyo's Olympic Village have been confirmed as members of South Africa's men's football team.

Games organisers announced in their daily update on Sunday that there had been 10 positive cases in the latest round of testing, taking the overall total this month to 55.

That includes three individuals based in the athletes' village, with an event official previously testing positive on Saturday.

The South African Football Association released a statement later on Sunday confirming Thabiso Monyane and Kamohelo Mahlatsi were the pair to return positive tests.

Orlando Pirates right-back Monyane and Moroka Swallows attacking midfielder Mahlatsi, plus video analyst Mario Masha, will now isolate in a hotel room for 14 days.

A fourth South African participant, rugby sevens coach Neil Powell, also produced a positive result. All four individuals tested negative before flying to Japan this week.

Team South Africa chief medical officer Dr Phatho Zondi said in a statement: "Every member of Team South Africa required full medical clearance as an eligibility criteria. 

"In addition, they were encouraged to isolate for two weeks pre-departure, monitor health daily, report any symptoms, and produce two negative nasopharyngeal PCR tests taken within 96 hours of departure, as per Tokyo 2020 requirements.

"The timing of the positive results suggests that the PCR test in these individuals was done during the incubation period of the infection, which is how they could be negative in South Africa and then positive in Japan. 

"They are now in isolation where they will continue to be monitored and will not be allowed to train or have any physical contact with the rest of the squad."

South Africa are scheduled to face tournament hosts Japan in their opening Group A game next Thursday, before taking on France and Mexico on July 25 and July 28 respectively.

Sunday's news of two athletes testing positive for COVID-19 inside the athletes' village will raise further concerns over the Olympics going ahead as planned.

The 2020 Games, already delayed by a year due to the global health pandemic, officially begins on Friday and will be held mostly without spectators due to a state of emergency being declared in Tokyo.

Infection rates in the Japanese capital have topped 1,000 for four days running.

Around 11,000 athletes from 205 national Olympic committees are expected to stay at the village over the next three weeks.

International Olympic Committee president Thomas Bach reiterated on Saturday that the first positive case posed no risk to the Japanese population.

"We are well aware of the scepticism a number of people have here in Japan," he added at a news conference. "My appeal to the Japanese people is to welcome the athletes for their competitions."

Ronald Koeman believes Spain should have given Barcelona teenager Pedri a rest rather than call him up for the Olympic Games.

The midfielder was a key part of the Spain squad that reached the semi-finals of Euro 2020, becoming the first ever player to start six games in a single European Championship or World Cup aged 18 or below.

Instead of being given time off before the start of Barcelona's LaLiga campaign, Pedri is in Japan for the Olympic football tournament.

Spain play their first game in Group C against Egypt on July 22 before fixtures with Argentina and Australia.

Koeman told a media conference: "Pedri has played a lot. We will have to give him a break, everyone needs it during the [European] summer. 

"As Pep Guardiola said, playing two important tournaments in the summer is too much, but we can't do anything. 

"Pedri's European Championship was phenomenal. At the age of 18 he has played almost all the complete matches, with an impressive maturity. 

"His football continues to improve and he is a very honest and calm boy. He lives for football. He is an example of how to be a young man at Barca.

"It is important for our grassroots football, that young people see that they are in a club that gives them opportunities."

Also in Spain's squad for the tournament is defender Eric Garcia, who re-joined Barca from Manchester City on a free transfer.

Koeman tipped the 20-year-old former Barca academy player to have a big impact on the first team when he is able to link up with the club following the Olympics.

"He has had a great European Championship," Koeman said. 

"He comes from here and, despite his youth, he already has a lot of experience. He plays in the same position I did. 

"With the ball he is very good and we can improve from behind with him. He also has projection and a great future ahead."

Meanwhile, Koeman hopes Ousmane Dembele can make a swift return from injury.

The France forward, whose contract at Camp Nou expires at the end of the 2021-22 season, is recovering from surgery on a knee injury sustained at Euro 2020 that is expected to keep him out for four months.

Dembele's career since his move to Barca from Borussia Dortmund for €105million four years ago has been blighted by injury setbacks.

The 24-year-old has managed just 54 LaLiga starts in four seasons at Camp Nou, while last season he completed 90 minutes in the league on just five occasions.

"I am very disappointed with his injury," Koeman added.

"Also, the situation with his contract is complicated. It is a pity for himself and for us. 

"He brought us a lot last year, different from what we have. I hope he can come back soon."

Two athletes in Tokyo's Olympic Village have tested positive for coronavirus ahead of the Games, organisers confirmed on Sunday.

The pair - listed as non-residents of Japan - will now isolate in a hotel room for 14 days. It takes the total number of known cases in the athletes' village to three, after an official had also tested positive.

There has already been a total of 55 cases linked to the Olympics this month, 10 of which were added to the list on Sunday, with another athlete from outside the village also contracting the virus.

Infection rates in Tokyo have topped 1,000 for four days running, raising further concerns about the global event going ahead.

The 2020 Games, delayed by a year due to the global health pandemic, officially begins on Friday and will be held mostly without spectators due to a state of emergency being declared in Tokyo.

Around 11,000 athletes from 205 national Olympic committees are expected to stay at the village over the next three weeks.

International Olympic Committee president Thomas Bach reiterated on Saturday that the first positive case posed no risk to the Japanese population.

"We are well aware of the scepticism a number of people have here in Japan," he added at a news conference. 

"My appeal to the Japanese people is to welcome the athletes for their competitions."

Japan men's football captain Maya Yoshida has called on Olympics organisers to reconsider their decision to stage the Tokyo Games behind closed doors.

The call to ban spectators from attending events was taken earlier this month after Japan's capital city was placed into a state of emergency amid rising COVID-19 cases.

However, fans are still able to attend certain other sporting contests within the country away from the Olympics, such as Japan's friendly with Spain in Kobe on Saturday.

A socially distanced crowd was present for the 1-1 draw and Yoshida has questioned why locals will not be permitted to attend matches when the Games begin next week.

"I think a lot of people's tax money is going to hold these Olympics," Yoshida is quoted as saying by the Asahi newspaper.

"Despite that, people can't go and watch. So you wonder about who the Olympics is for, and what it is for. Of course athletes want to play in front of fans."

Tokyo 2020 officials confirmed the first coronavirus case at the Olympic Village on Saturday, since when two athletes have reportedly tested positive.

"Our families have sacrificed and put up with things, they supported us when we were competing in Europe," Sampdoria defender Yoshida added.

"It's not just the players who were competing, but the family members, every one of them.

"So if they can't watch the match, well who and what is that match for, there is that question. I really hope we can reconsider that seriously."

Japan will take on South Africa in their opening Group A game on Thursday, before facing Mexico and France. The top two sides will advance to the quarter-finals.

Germany's men's Olympic football head coach Stefan Kuntz says his players had no option but to walk off the field with five minutes remaining of their match against Honduras after defender Jordan Torunarigha was allegedly racially abused.

Saturday's pre-Tokyo 2020 friendly, which was played behind closed doors in Wakayama, was brought to an early close shortly after Felix Uduokhai had cancelled out Douglas Martinez's first-half opener.

A tweet from the official Germany team account read: "The game has ended five minutes early with the score at 1-1. The Germany players left the pitch after Jordan Torunarigha was racially abused."

The Honduras national team later tweeted that the incident "was a misunderstanding", but Kuntz stands by his side's decision to take a collective stand by making their way off the pitch.

"When one of our players is racially abused, playing on is not an option," Kuntz said at his post-match news conference.

"It was a strong statement. After the situation calmed down, the whole Honduras squad came to us and apologised. That was the end of the topic for us.

"We talked to each other about whether we should do anything else, but Jordan said 'No, that was a strong enough statement'.

"We want to end the subject there because now we fly to Yokohama to prepare for our next game."

Torunarigha plays for Hertha Berlin at club level and has represented Germany from Under-16s to Under-23s level.

The 23-year-old was also the alleged victim of racist abuse in February 2020 in a DFB-Pokal match between Hertha and Schalke.

Following the latest incident on Saturday, Hertha offered their support to the centre-back, tweeting of the decision to leave the pitch in unison: "That is the only right decision!"

"His team-mates picked him up straight away and hugged him for a few minutes," added Kuntz, who earned 25 caps for the Germany men's senior side in his playing days.

"He was very relaxed and you could tell he was happy to be with us. Afterwards we even started to joke a bit again.

"This team is great. It helps of course when you can see that your colleagues support you so much. It's also a strong statement from Jordan to say what we did was enough."

Germany face Brazil on July 22 in their opening Group D fixture at the Olympics, before taking on Saudi Arabia and Ivory Coast.

Germany's men's football team walked off the pitch in a pre-Tokyo Olympics friendly against Honduras after defender Jordan Torunarigha was allegedly racially abused.

Saturday's match in Wakayama was tied at 1-1 when abandoned with five minutes to go, moments after Felix Uduokhai had cancelled out Douglas Martinez's first-half opener.

The Germany national team's official Twitter account later confirmed the reason for the game, which was split into three 30-minute sessions, being cut short.

"The game has ended five minutes early with the score at 1-1," the tweet read. "The Germany players left the pitch after Jordan Torunarigha was racially abused."

Torunarigha plays for Hertha Berlin at club level and has played for Germany from Under-16s to Under-23s level.

The 23-year-old was also the alleged victim of racist abuse in February 2020 in a DFB-Pokal match between Hertha and Schalke.

Following the latest incident on Saturday, Hertha offered their support to the centre-back, tweeting of the decision to leave the pitch in unison: "That is the only right decision!"

Germany face Brazil on July 22 in their opening Group D fixture at the Olympics, before taking on Saudi Arabia and Ivory Coast.

Jade Jones is in the hunt for an historic third successive gold medal in taekwondo at the Tokyo Olympics, and she is doing all she can to ensure coronavirus does not derail her hopes.

The Tokyo Games are set to start next week, though no fans will be allowed to attend as Japan deals with another spike in COVID-19 cases.

Jones tested positive for the illness earlier this year, and the 28-year-old has since had both doses of a vaccine, though that does not mean she cannot still contract the virus.

She won gold at London 2012 and Rio 2016, with no taekwondo athlete having ever won three straight gold medals in the discipline. Jones is also hoping to become the first British female Olympian to claim the top prize at three consecutive Games.

However, her participation would be ended if she tests positive for coronavirus, and Jones explained the lengths which she and her team are going to in order to avoid such a situation.

"The hardest bit is being petrified you're going to test positive," Jones, who is based at the Keio University in Minato City, told the Evening Standard. "I've had the vaccines and I've had COVID so it's highly unlikely.

"But I still don't want to get a positive test because that means game over, you're out. To have your Olympic dreams pending on that is scary. I constantly wear the mask.

"My hands are raw from the amount of hand gel I've been putting on, we walk in single file to training, literally a little traffic system so no-one comes near us and we stay in that same bubble.

"To be fair, I'm quite anti-social anyway, so it works well for me. I've got an excuse now. Got to keep my distance. Where we have our meal there's a sticker on the table saying 'keep conversation to a minimum'."

Indeed, on Saturday, Jones' fears might only have been heightened by a positive COVID-19 case being discovered in the athletes' village.

Jones, though, is still enjoying the atmosphere in Tokyo, despite the strict restrictions.

"I thought because of COVID it's not going to be the same, it's going to be rubbish, it's not going to compare to London and Rio," Jones said.

"I got here and it seems the same. Obviously, you have to wear the mask but I still feel like that little kid walking around saying 'this is amazing'. Just wearing the kit, I just feel proud to be here again."
