Andy Murray sympathises with Emma Raducanu's struggles since winning the US Open last year, noting her sudden rise to stardom has been "extremely difficult to navigate."

Murray also revealed he remains torn on whether he would remain in tennis after retiring, admitting an interest in coaching but saying he was not yet certain he would follow that path.

The two British hopes will both feature on Centre Court when Wimbledon begins on Monday, with Raducanu facing Alison Van Uytvanck before Murray takes on Australia's James Duckworth.

Raducanu has endured an injury-hit 2022 season, only lasting 36 minutes when making her first grass-court appearance of the year at Nottingham earlier this month, but has since declared herself "ready to go" ahead of the year's third grand slam.

Recalling Raducanu's stunning triumph in New York last September, Murray said the way she was thrust into the public eye has complicated her 2022 campaign.

"I never experienced what she experienced, your life changing overnight," he told the Telegraph.

"It's impossible to know if everyone who is then involved with you is looking out for your best interests. You know that your family wants the best for you. The families are of course going to make mistakes, because it's new to everybody.

"I would have worked with coaches when I was younger who were not necessarily the right people for me – and management companies, too.

"You question; 'Do they want what’s best for you or do they want to make lots of money off you?'

"It's extremely difficult to navigate."

Murray and Raducanu are the only British players to win a grand slam singles title since Virginia Wade's Wimbledon triumph in 1977, with the Scot's last major win coming at the All England Club Wimbledon in 2016.

Ahead of his tilt at a third triumph at SW19, the 35-year-old said his post-retirement plans remained uncertain.

"I have interests and things outside of tennis and I know that when I finally finish, everything will be fine. The world won't end," he added.  

"Whereas maybe when I was 25, and maybe at times even at the beginning of the [Amazon Prime] documentary in 2017 [about his injuries], I was still a bit like that.

"I've always been interested in coaching. There's also a chance that I might not be involved in tennis anymore.

"I feel right now that I would always have some involvement in tennis, but there are also times when I've been away from the sport and I've not watched any of the tournaments.

"That's when I'm just at home with the kids. It's pretty full-on, that side of things."

When Wimbledon ended last year, there were two great takeaways from the tournament: Novak Djokovic would soon be pulling away in the grand slam title race and Ash Barty was beginning a new era of dominance.

Both seemed to be knock-ins, and yet neither has come to pass. Djokovic missed out on a calendar Grand Slam in New York before being banished from Australia, and despite drawing level with Rafael Nadal and Roger Federer on 20 grand slams with his Centre Court triumph, he now finds himself two adrift of the Spaniard again.

Barty, meanwhile, has left her own party. The then world number one stunned the tennis world by retiring in March, having added the Australian Open she so craved to her trophy cabinet.

Djokovic and Iga Swiatek head into Wimbledon, which begins on Monday, as the top seeds.

Stats Perform has used Opta facts to consider what the men's and women's singles might deliver.

KING ROGER'S REIGN IS OVER, BUT DJOKOVIC AND NADAL KEEP GOING STRONG

There will come a time when the Wimbledon favourite is not one of the 'Big Three'. That time is not now.

Djokovic is the man most likely, as he targets his fourth straight Wimbledon title and seventh overall; since 2011, when he beat Nadal in the final, the Serbian has only been absent from the trophy match three times (in 2012, 2016 and 2017).

His winning run of 21 matches at Wimbledon is the fifth-longest in the men's singles. Bjorn Borg holds the record (41 between 1976 and 1981).

The last player other than Djokovic, Nadal, Federer and Andy Murray to win the Wimbledon men's title was Lleyton Hewitt in 2002. Federer is absent this year and may have played his last Wimbledon.

Nadal has won Wimbledon twice, in 2008 and 2010. He won the French Open, Wimbledon and the US Open in 2010, the only season of his career when he has won three slams. This year, at the age of 36, he has the Australian and French Open trophies already locked away, potentially halfway to a calendar Grand Slam, last achieved in men's singles in 1969 by Rod Laver.

Should Nadal pull off another major coup, it would make him only the second man in the Open Era (from 1968) to win the season's first three singles slams, after Laver in 1969 and Djokovic last year.

Can the rest hope to compete?

What of Murray? Well, only Federer (19), Sampras (10), Laver and Jimmy Connors (both nine) have won more ATP titles on grass than the Scot in the Open Era. If he recovers from an abdominal strain, he has a shot at reaching the second week. He will of course have the full backing of the Wimbledon crowd.

Last year's runner-up Matteo Berrettini is fancied more than Nadal by many, having won Stuttgart and Queen's Club titles in the build-up.

There has not been an American men's singles champion since 2000, and although the United States has six players seeded, more than any other nation, it seems a safe enough assumption we will be saying a similar thing again in 12 months' time.

Third seed Casper Ruud has never won a singles match at Wimbledon, while fourth seed Stefanos Tsitsipas has not had a win since reaching the fourth round in 2018. Daniil Medvedev, the world number one, cannot compete at The All England Club after their contentious decision to ban Russian and Belarusian players due to Russia's invasion of Ukraine.

IF SERENA CAN'T CHALLENGE SWIATEK, WHO CAN?

From the jaws of retirement, Serena Williams is back. Silence from the 40-year-old about her intentions had become almost deafening, and yet here she is, back at Wimbledon on a wildcard, hoping to rekindle the old magic.

Because she has pushed back against the doubters for over two decades now, you have to take this seriously. Her haul of 23 grand slams is one short of Margaret Court's all-time record and Williams would dearly love to at least match it.

Three years ago, Williams became the oldest player to reach Wimbledon's women's singles final when she lost to Simona Halep. Six years ago, she was the oldest champion when she beat Angelique Kerber.

Only four women in the draw this year besides Williams have been champion before: Petra Kvitova (in 2011 and 2014), Garbine Muguruza (in 2017), Kerber (in 2018) and Halep (in 2019).

World number one Iga Swiatek starts as favourite. Junior Wimbledon champion four years ago, she has scooped two women's French Open titles since then and is on a 35-match winning streak.

After triumphing at Roland Garros in early June, Swiatek will hope to become the first woman since Kerber in 2016 (Australian Open and US Open) to win two singles slams in the same season.

The only competitive warm-up for Williams came in two doubles matches at Eastbourne, having not played since sustaining a hamstring injury at Wimbledon last year. The seven-time champion might consider it a challenge that there has never been an unseeded Wimbledon women's singles finalist during the Open Era.

The women's top two seeds have not met in the final since Serena faced her sister Venus in the 2002 title match, so don't hold your breath for a Swiatek versus Anett Kontaveit showpiece on July 9.

Could Gauff be best of the rest?

Coco Gauff made a breakthrough with her run to the French Open final. Although she was blown away by Swiatek, for the 18-year-old American it was another mark of progress. Gauff reached the fourth round in Wimbledon in 2019 (lost to Halep) and 2021 (lost to Kerber).

Fitness is likely to be the key factor in how US Open champion Emma Raducanu fares at her home grand slam, given her injury problems. Raducanu reached the fourth round on a wildcard last year and the 19-year-old will attempt to become the first British woman to reach that stage in back-to-back seasons since Jo Durie (1984, 1985).

Ons Jabeur, meanwhile, should not be discounted. The world number three reached the quarter-finals at SW19 last year and heads to Wimbledon having won on grass at the Berlin Open, albeit Belinda Bencic had retired hurt in the final.

The likes of Gauff, Raducanu and 21-year-old Swiatek will attempt to become the youngest woman to lift the trophy since 17-year-old Maria Sharapova triumphed in 2004.

A first-round exit for Swiatek would leave the event wide open, but don't count on it. In the Open Era, only three times has the top-seeded woman lost in round one: Steffi Graf in 1994 and Martina Hingis in 1999 and 2001.

Novak Djokovic says he has "nothing but respect" for Rafael Nadal as the Spaniard strives to create "even more of a successful legacy".

Nadal now has 22 majors to his name after winning the Australian Open and French Open this year – two more than Djokovic and Swiss great Roger Federer.

Victory at the French Open earlier in June was Nadal's 14th at Roland Garros, which is a whopping eight more than anyone else in the open era.

Djokovic, who kicks off his bid for a fourth consecutive Wimbledon title against Kwon Soon-woo on Monday, is in awe of Nadal's achievements, describing the 36-year-old as an "amazing champion".

"He had a surgery in the second part of the last year and coming back after that and winning a grand slam right away is something that is really impressive," the Serbian told a media conference on Saturday.

"[He is] making history with grand slam wins and at Roland Garros, the tournament where he has won most titles.

"Just for what he has achieved, keeps on doing on the court; he has a great fighting spirit, and he is an amazing champion.

"Just in general, the things he is trying to do to create even more of a successful legacy is something you have to respect and admire even though I am one of his biggest rivals. I have nothing but respect for what he has achieved."

Djokovic's refusal to get a COVID-19 vaccination has hampered his playing time this year, yet the 35-year-old is confident that will not hold him back as he bids for a seventh title at The All England Club.

"I didn't have any lead up tournaments but I've had success at Wimbledon before without having any official matches," he added.

"I had success with adapting quickly to the surface so there is no reason to believe why I cannot do it again. I'm very pleased and happy to be back at the tournament that was always my childhood dream, the one I wanted to win. Hopefully I continue that run.

"I would love to be in the position to fight for another trophy, I would like to be in the last match and eventually make history at this tournament.

"As a seven, eight-year-old boy I dreamed of winning Wimbledon and becoming number one. That was the biggest motivation I had as a kid.

"Pete Sampras, when he won his first Wimbledon, was the first tennis I watched on the TV. Pete has won it seven times. Hopefully I can do the same this year."

Novak Djokovic has accepted it is unlikely he will play at the US Open, as the Wimbledon top seed insisted he has not changed his mind on the COVID-19 vaccination.

Djokovic was unable to compete at the Australian Open earlier in 2022 after he was deported – following a drawn-out legal case with Australia's federal government – for not being vaccinated against coronavirus.

The Serbian has spoken out against mandatory vaccinations and when asked on Saturday by reporters at Wimbledon if he had closed his mind to the idea of being vaccinated before the US Open begins, he said "yes".

That means, as it stands, Djokovic will be unable to enter the United States due to being unvaccinated.

However, while frustrated that he will likely miss out on another grand slam this year, the 35-year-old suggested he is now even more motivated to go on and win Wimbledon for a seventh time, which would take him level with Pete Sampras and behind only Roger Federer, who has eight All England Club titles to his name.

Djokovic told reporters: "As of today I'm not allowed to enter the States under these circumstances. That is an extra motivation to do well here.

"Hopefully I can have a very good tournament as I have done in the last three editions. Then I'll have to wait and see.

"I'd love to go to the States but as of today that's not possible. There's not much I can do any more. It's up to the U.S. government on whether they allow unvaccinated people to go into the country."

Djokovic was at the centre of the controversy ahead of the season's first major, but the third grand slam of 2022 has been contentious for other reasons.

The All England Club made the decision to ban all Russian and Belarusian players, including men's world number one Daniil Medvedev, from competing, due to Russia's invasion of Ukraine. The call received criticism and, as a result, Wimbledon has been stripped of any ranking points by the WTA and ATP.

However, Djokovic is no longer as concerned about those points as he once was, as he instead looks to move back to within one major title of Rafael Nadal, whose tally stands at 22.

"I don't want to say ranking points are not important for me, of course they are, but they are not as important as they were for me," he said.

"Now I'm not really chasing the ranking as much as I have. I was breaking the record for longest weeks at number one and after that it wasn't as important for me in terms of priority.

"Of course, I understand that 90 per cent of players will be more affected by the points. Of course this year I did not have the chance to defend 4,000 points in Australia but my priorities now are different so I’m not as affected."

Djokovic, though, does feel it is harsh that Russian and Belarusian athletes are unable to play at SW19.

He said: "I just don't see how they have contributed to anything that has happened. I don't feel it’s fair. 

"I feel like they deserve to win, compete, they are professional athletes. None of them have supported any war or anything like that. 

"I understand both sides. It's hard to say what is right and wrong. Putting myself in a position where someone would ban me from playing because of circumstances that I have not contributed – I do not think that is fair."

Six-time champion Novak Djokovic will take centre stage on day one at Wimbledon along with home hopes Emma Raducanu and Andy Murray.

The All England Club has announced the schedule of play for Monday, when the 2022 tournament will get under way.

As is tradition for the defending champion, Djokovic, who defeated Matteo Berrettini in last year's men's singles final, will take part in the first match on Centre Court when he plays against Kwon Soon-woo.

Djokovic will be bidding for a fourth Wimbledon title in succession following triumphs in 2018, 2019 and 2021, after the cancellation of the 2020 championships.

US Open champion Raducanu has also been selected to appear at Centre Court on the opening day.

Raducanu will take on Alison Van Uytvanck hoping to kick off a successful campaign in front of her home crowd, having burst onto the scene at Wimbledon last year with a shock run to the fourth round.

And another Briton, two-time winner Andy Murray, will be involved in the third and final match on the prestigious court when he faces James Duckworth of Australia.

Murray will be hoping to better last year's third-round berth at SW19 after impressively reaching the Stuttgart Open final this month, losing to Berrettini after notable wins over Stefanos Tsitsipas and Nick Kyrgios.

Ons Jabeur, Angelique Kerber and Carlos Alcaraz are the big names selected for action on Court One on Monday.

And it has been confirmed that, in the absence of retired champion Ash Barty, women's number one seed Iga Swiatek will open the action on Centre Court on Tuesday when she plays Jana Fett. Swiatek said she felt "very privileged" to be opening the proceedings on day two.

Rafael Nadal, who has won the opening two men's grand slams this year, is also expected to begin his campaign on day two, as is seven-time women’s champion Serena Williams on her return from injury.

Rafael Nadal does not know how long his troublesome foot will hold up and cannot be "super happy" while the threat of injury lingers, but he is ready to attack Wimbledon.

Nadal, the 22-time major champion, is halfway to a calendar Grand Slam, having won the Australian Open and French Open.

Yet those successes have come despite a long-term foot problem he has battled, requiring pain-killing injections before every match at Roland Garros.

Nadal's Wimbledon participation was in question for some time, but he underwent two courses of radiofrequency injections in a bid to ease the pain and be fit enough to challenge at the All England Club.

That is now the case, he says, even if he has to accept his status is unpredictable day to day.

"It's obvious that if I am here, it's because things are going better," the Spaniard told a news conference. "If not, I would not be here.

"So I'm quite happy about [how] the things have evolved. I can't be super happy because I don't know what can happen.

"First of all, I can walk normal most of the days, almost every single day. That's for me the main issue. When I wake up, I don't have this pain that I was having for the last year and a half, so I'm quite happy about that.

"And second thing: practising. I have been overall better.

"Since the last two weeks, I didn't have one day of these terrible days that I can't move at all. Of course, [some] days are better; [some] days are little bit worse."

He added: "I can't tell you if I'm going to be in that positive moment for one week, for two days, or for three months.

"Of course, the treatment that I did didn't fix my injury. It is not improving my injury at all but can take out a little bit the pain. That's the main goal.

"Sometimes the things in the medical world, mathematics is not predictable 100 per cent.

"But in theory, that can help the foot because it's about the nerve. You touch the nerve, so then the nerve is like asleep in some way for a while, but then recovers.

"So how long the nerve is going to be that way, I can't tell you. It's something that we need to discover."

Taylor Fritz earned his third ATP Tour title and second at the Eastbourne International as he defeated fellow American Maxime Cressy 6-2 6-7 (4-7) 7-6 (7-4) in Saturday's final.

Three years on from Fritz's breakthrough tour triumph against Sam Querrey – another compatriot – at the same event, the world number 24 was celebrating again in the last tournament before Wimbledon.

Paris-born opponent Cressy had defeated a trio of home hopefuls in succession in Britons Dan Evans, Cameron Norrie and Jack Draper to reach this stage, but Fritz had just too much.

While the Indian Wells Masters champion had not lost a break all week and maintained that record through the decider, he was taken all the way.

"I played about as well as I could possibly play today, and it still came down to the final couple of points," Fritz said afterwards. "It couldn't have been much closer."

That had not appeared likely after an opener in which Fritz's return game dominated 6ft 6in serve-and-volley specialist Cressy, who was broken immediately following a double-fault.

That was one of four in the first set – as many as in three against Draper – as Cressy won just half of his service points, broken again to love.

Yet neither player faced another break point, with a pair of tie-breaks required to settle the title.

The first went the way of Cressy, forcing a decider as a pair of powerful forehands finally broke down Fritz, but he required treatment between sets and had clearly tired by the closing stages.

The latest in a series of Fritz lobs proved beyond Cressy, not that the result should have come as any surprise – improving the champion's career record in deciding tie-breaks to an astonishing 20-3.

Stefanos Tsitsipas claimed the first grass-court title of his career as he edged Roberto Bautista Agut in the Mallorca Open final.

Playing in his fourth final of 2022, Tsitsipas looked to have victory in his grasp when he broke for a 3-1 lead in the decisive set.

He surrendered his initiative when he was broken while serving for the match at 5-3.

However, Tsitsipas made no mistake in the eventual tie-break, surging to a 6-4 3-6 7-6 (7-2) victory.

The win secured Tsitsipas' second title of the year following his May success in Monte Carlo.

Tsitsipas will hope his performance on the grass in Mallorca translates to a strong performance at Wimbledon, where he has gone past the first round only once.

He will face Alexander Ritschard in the first round at the All England Club on Tuesday.

Rafael Nadal is halfway to a calendar Grand Slam, a feat that would mark the crowning point of any player's career.

Yet the Spanish great does not have to look far back into history to see how quickly that dream can be scuppered, with Novak Djokovic having fallen agonisingly short of a sweep of all four majors only last year.

As perhaps the most grounded player in tennis, Nadal heads into Wimbledon well aware that winning the first two majors of the year is no guarantee of any future success.

At the age of 36, and with a foot problem that requires careful maintenance, it would be arguably the most remarkable feat in the Open Era if Nadal were to add the Wimbledon and US Open titles to his Australian Open and French Open triumphs.

Such dominance is scarce in tennis, and Rod Laver was the last player to scoop all four men's singles titles at the majors, all the way back in 1969.

Steffi Graf won all four on the women's side in 1988, and it seemed a knock-in that Serena Williams would do likewise in 2015 when she headed to the US Open with three majors already bagged.

But Williams famously came unstuck when she faced Roberta Vinci in the semi-finals, while Djokovic went even closer in 2021, losing to Daniil Medvedev in the final at Flushing Meadows.

Here, Stats Perform examines the daunting challenge of scooping all four slams consecutively.

WHAT THE GREAT CHAMPIONS SAY

Before tennis reached its Open Era, which marked the dawning of professionalism on the tour, Laver won his first calendar Grand Slam in 1962.

He said later, quoted by the Tennis Hall of Fame: "It was a thrill to come off the court knowing I had won all four majors in one year. But I never felt like I was the best, never felt that way. I just happened to have a good year."

His 1969 dominance came a year after Laver returned to the majors, following a five-year exile while he played professional tennis elsewhere. When the majors allowed professionals to compete alongside the amateurs, 'Rocket Rod' was again unstoppable.

Laver turned 31 in 1969 and did not win any further grand slam singles titles in his career after that astonishing season, but that second perfect season sealed his legacy as an all-time great.

Stefan Edberg won a boys' singles clean sweep in 1983, but Laver remains the only player to win the men's singles full set in a calendar year since American Don Budge captured all four in the 1938 season, the first time it was achieved by a man. Maureen Connolly and Margaret Court achieved calendar Grand Slams in women's singles in 1953 and 1970 respectively.

A non-calendar Grand Slam was accomplished by Djokovic, when he won Wimbledon, the US Open, Australian Open and French Open consecutively across the 2015 and 2016 seasons. Yet no man other than Laver, Budge and Djokovic has won all four singles crowns in succession.

It has been 11 years since Nadal himself went close. He went to the Australian Open in 2011 with the Roland Garros, Wimbledon and US Open trophies in the bag, looking to complete the set.

"I am sure it's going to be the only one opportunity that I'm going to have in my life," said Nadal that year. "I'm not going to have more of these opportunities to win all four in a row.

"I think it is almost impossible. It is very, very difficult, no? Tennis is a very competitive sport and there is not a lot of difference between players. So a lot of matches are decided in a few balls. So for that reason it is very difficult to have one player winning everything. That's the truth."

Nadal, hampered by injury, lost in the Melbourne quarter-finals to David Ferrer in 2011 and had not won back-to-back slams since, until this year's surprise double. 

REACHING PRESSURE POINT

It is too soon to think that Nadal has a glorious chance to land all four big ones this year. After all, although he has won Wimbledon twice before, those triumphs came in 2008 and 2010, and he has a chronic foot problem. He has required radiofrequency ablation treatment in the past fortnight, preventing nerves in his foot sending messages to his brain.

He fell to Djokovic in the 2011 Wimbledon final and has not been back to the title match since, suffering a run of disappointing early exits in London before reaching semi-finals in 2018 and 2019, his last visits to the tournament.

Djokovic is a heavy favourite for this year's title, but it would be bold to entirely rule out Nadal, particularly given that as the second seed he cannot run into Djokovic until the final. Particularly given that he is Rafael Nadal, and prone to doing stupendous things.

Serbian Djokovic, a year Nadal's junior, would be able to tell his great rival just how intense the strain can become when a calendar Grand Slam becomes a serious prospect.

Speaking in November last year, two months after Medvedev denied him in New York, Djokovic said: "I'm very relieved that the grand slam season was done, because I felt a tremendous pressure unlike anything I felt in my life.

"It was an interesting experience, and I'm very satisfied with the way I played in grand slams, three wins and a final. There are much more positive things to be grateful for and to look at than negative."

Like Djokovic, Serena Williams has managed the non-calendar Grand Slam before, with the American first achieving that from the French Open in 2002 to the Australian Open in 2003, and in 2015 she was aiming for five slams in a row when she arrived at the US Open, having begun her dominant streak at her home grand slam the previous year.

That would have meant Williams sealed each of the 2015 slams, and losing to Vinci led to stark frustration, underlined by a terse response to the question of how disappointed she felt by the result.

"I don't want to talk about how disappointing it is for me," Williams said. "If you have any other questions, I'm open for that."

Sometimes, players get ahead of themselves when looking at the season ahead, and Naomi Osaka had a calendar Grand Slam in her thoughts after winning the season-opening Australian Open in 2019.

She had also triumphed at the US Open at the end of 2018, and the Japanese star was beginning to think she might enjoy an invincible year at the majors, only to stumble to a third-round French Open defeat to Katerina Siniakova.

Osaka said: "I think I was overthinking this calendar slam. For me this is something that I have wanted to do forever, but I have to think about it like if it was that easy, everyone would have done it."

Roberto Bautista Agut stands in the way of Stefanos Tsitsipas and his first grass-court title.

Making his debut at the Mallorca Championships, Tsitsipas sealed his maiden appearance in a grass-court final by cruising past Benjamin Bonzi 6-4 6-4 on Friday.

The world number six has now reached four finals this season, having lost two of the previous three – winning on clay at the Monte Carlo Masters.

It was the second meeting between the pair in as many weeks, with the Greek having also downed Bonzi at the Halle Open.

And Tsitsipas now has a chance to warm up for Wimbledon in winning fashion.

"It was a good match. I am very happy today," Tsitsipas said in his on-court interview. "I have played a final a week before a grand slam before. It was the year I made the final at Roland Garros, in Lyon.

"It worked out pretty well to have that final and consistency of matches. It is different this time. We are talking about a different surface, so we will see."

Tsitsipas has now claimed a tour-leading 39 wins this season, but standing between the 23-year-old and silverware is Spaniard Bautista Agut, who reached a 20th career final by beating Antoine Bellier 7-6 (7-5) 6-2.

Like Tsitsipas, Bautista Agut is aiming for a second title of the season.

At the Eastbourne International, two Americans will vie for the title after Indian Wells Masters champion Taylor Fritz saw off a tough challenge from Alex de Minaur while Maxime Cressy defeated home favourite Jack Draper 7-6 (7-5) 6-7 (2-7) 6-3.

Fritz, who triumphed at Eastbourne in 2019 – similarly against an American, in Sam Querrey – but has found his best form hard to come by of late, also needed three sets to get the better of De Minaur, eventually succeeding 6-1 6-7 (5-7) 6-3.

"It's amazing," Fritz said. "I was having a bit of a rough start coming back from injury to the grass season, and then I came here and the first day I was here I just immediately felt like I was playing good tennis again.

"I just have a lot of confidence being here, obviously great memories, so I'm really excited to come back out and play for the title again."

Former Wimbledon doubles champion Pam Shriver has said she does not disagree with the decision to ban Russian and Belarusian players from this year's tournament.

Shriver landed 21 women's doubles grand slam titles, of which 20 came in partnership with Martina Navratilova, and 112 career doubles titles in all, and she also claimed 21 singles tournament wins.

Russian and Belarusian players have been banned from this year's Wimbledon due to the ongoing Russian invasion of Ukraine.

Speaking to Stats Perform, Shriver – who won five women's doubles championships with Navratilova at Wimbledon – said while she did not like that it was a decision that needed to be made, she did not object to it.

"War is messy, right? War is tragic. It's been a horror show for Ukrainian people," said American Shriver. "And there's a lot of Ukrainian professional tennis players that are just living through hell.

"Obviously, the decision has been made to try and have the tightest of sanctions. So when you think about the industry of pro tennis, if we're going to have sanctions as well, then Wimbledon [should too], and I understand the UK government has put some pressure throughout the country to not do business with Russians during this time.

"I wish they had never had to make the decision, but I think under the circumstances, I can't say I disagree [with it]."

Shriver also said the decision from the ATP, WTA and ITF to remove ranking points from this year's tournament was "really unfortunate".

However, she does not believe it will make Wimbledon seem like an exhibition, saying: "It's not an exhibition because of the prize money and because of the prestige of winning a Wimbledon title.

"Those are actually the two main things. I think the points are third, and so you're missing the third most important aspect, but the prize money is huge, and [the tournament] will be just as prestigious as ever."

As a result of the ban on Russian players, men's world number one Daniil Medvedev will not be in attendance at SW19, but Shriver does not think it will diminish the competition.

"You know, maybe some years it would [be a problem that Medvedev is not there] but... you're going to have the number one seed being [Novak] Djokovic and number two seed being [Rafael] Nadal," she said.

"When you have the player who has more majors than anybody else ever in the men's game at 22, Rafa, and you have Novak trying to win his fourth straight Wimbledon and his seventh overall and trying to chase Rafa's 22, I think that's going to hide the fact we don't have a number one.

"It's going to be an unusual year to not have rankings one and two [Medvedev and the injured Alexander Zverev], but I feel like the names on the men's side, [Carlos] Alcaraz, [Matteo] Berrettini, [Hubert] Hurkacz got to the semis last year, the two Canadian guys [Felix Auger-Aliassime and Denis Shapovalov].

"I feel like there's still such great depth and with Rafa and Novak leading the way, it's fine."

Novak Djokovic and Rafael Nadal avoided the looming threat of Andy Murray and Nick Kyrgios in Friday's Wimbledon draw.

With both Murray and Kyrgios unseeded, they could have been drawn to face any of the top seeds, but it did not work out that way, most likely to everyone's satisfaction.

Instead, top seed and tournament favourite Djokovic drew South Korean Kwon Soon-woo, while Nadal was pitted with 23-year-old Argentinian Francisco Cerundolo.

Djokovic will be bidding for a seventh Wimbledon title and a fourth in succession following triumphs in 2018, 2019 and 2021, after the cancellation of the 2020 championships.

For second seed Nadal, who has won the Australian Open and French Open already this year to reach a record 22 men's grand slam singles titles, there is the possibility of a rare calendar Grand Slam.

He must carry off the title at Wimbledon for the first time since 2010 to stay in the hunt for that elusive clean sweep, last achieved in men's singles in 1969 by Rod Laver.

Murray, who like Nadal is a two-time former Wimbledon champion, was paired with James Duckworth of Australia and could face big-serving American John Isner in round two. Murray has been troubled by an abdominal strain in the past fortnight, and it remains to be seen whether the 35-year-old is in shape to be a contender.

Duckworth's countryman Kyrgios has been in fine form of late, reaching consecutive semi-finals in Houston, Stuttgart and Halle before he too suffered an abdominal twinge this week and withdrew from the Mallorca Championships. Kyrgios will start against Britain's Paul Jubb at Wimbledon.

A notable first-round clash saw three-time major winner Stan Wawrinka, in the draw on a wildcard, paired with Italian 10th seed Sinner, while Matteo Berrettini, runner-up to Djokovic last year, will play Chile's Cristian Garin.

Powerful Italian Berrettini, who has won the Stuttgart and Queen's Club titles on grass this year, features on Nadal's side of the draw, while in the top half Djokovic has the likes of Carlos Alcaraz and Hubert Hurkacz for company.

Alcaraz, the 19-year-old Spanish revelation who has won four titles already this year, was drawn to face the experienced German Jan-Lennard Struff in round one.

Men's third seed Casper Ruud has never won a singles match at Wimbledon, losing in the first round on his previous two appearances. The recent French Open runner-up will look to get off the mark on the SW19 grass against 34-year-old Spaniard Albert Ramos-Vinolas.

Top seed Daniil Medvedev crashed out of the Mallorca Championships following a straight-sets defeat by Roberto Bautista Agut in the quarter-finals.

Reigning champion Medvedev was a commanding winner when he locked horns with Bautista Agut in Halle last week.

But the Spaniard gained revenge this time around, prevailing 6-3 6-2 for his fourth victory in five meetings with the world number one.

"I had to play very good to beat Daniil," said the former Wimbledon semi-finalist. "He’s the number one; the last champion here in Mallorca. He just beat me a few days ago.

"I played a really compete match. I was more convinced with my game, hitting strong, very solid. I think I did a really good match."

Next up for the Doha champion is Antoine Bellier after the Swiss qualifier came from behind to defeat Dutchman Tallon Griekspoor 5-7 7-6 (7-5) 6-2.

Elsewhere, Stefanos Tsitsipas is through to his first tour-level semi-final on grass after eventually seeing off Marcos Giron 7-6 (7-5) 4-6 6-3.

The former Roland Garros runner-up, who hit 13 aces, claimed the crucial break in game eight of the deciding set to extend his record tally of wins for the campaign to 38.

The world number six will play Benjamin Bonzi in the last four after the Frenchman overcame Daniel Altmaier 6-3 6-4.

Meanwhile, Cameron Norrie was beaten in the quarter-finals of the Eastbourne International, the top seed going down 7-5 7-5 against Maxime Cressy.

The debutant hit 10 aces and won 80 per cent of points on his first serve to advance to a second tour-level semi-final of the season.

There, he will play Jack Draper, who built on his victory over Diego Schwartzman by downing compatriot Ryan Peniston 6-3 6-3 to seal his maiden ATP semi-final appearance.

Reigning champion Alex De Minaur overcame Tommy Paul 6-2 4-6 6-4 to set up a clash with 2019 winner Taylor Fritz, who claimed his seventh successive victory at Eastbourne after seeing off Alexander Bublik 6-3 6-2 in just 67 minutes.

Carlos Alcaraz does not believe he should be considered among the favourites to win Wimbledon given his lack of experience playing on grass. 

The teenage Spaniard is enjoying a breakout season, having won a pair of ATP Masters 1000 titles in Miami and Madrid and picked up further silverware in Rio de Janeiro and Barcelona. 

Alcaraz has been seeded fifth for just his second main-draw appearance at Wimbledon. Last year, he beat Yasutaka Uchiyama in five sets before falling to a straight-sets defeat against Daniil Medvedev. 

They are Alcaraz's only ATP Tour-level matches on grass, so his main focus heading to the All England Club is to simply improve his feel for the surface. 

"I don't mind being in the spotlight, I don't see it as pressure, but I've seen that I'm considered one of the favourites for Wimbledon. I don't see it that way at all," Alcaraz told the Spanish media. 

"There are many players who play better than me on grass. [Novak] Djokovic, Rafa [Rafael Nadal], [Matteo] Berrettini... We are going to try to gain experience on this surface. 

"Knowing how to move well on grass is very important. I think it's the key to being able to get good results. We're trying to improve in mobility and the small details that are more important on this surface. 

"Being more aggressive, trying to take advantage of the fact that I volley well – those things." 

Alcaraz is playing an exhibition tournament at Hurlingham this week and lost his opening match against Frances Tiafoe 6-4 6-2 on Thursday. 

The world number seven has been struggling with an elbow issue, but experienced no discomfort during his defeat. 

"A week ago, I couldn't train at all," he added. "I came here unsure if I was going to be able to play normally.

"The days I've been able to train I've felt quite well – zero pain in the elbow – and today there was no pain in the match with Tiafoe."

Nick Kyrgios has lamented the ATP Tour trialling off-court coaching, warning tennis will lose one of the "unique traits that no other sport had".

The ATP announced on Tuesday that off-court coaching will be tested in the second half of the season, with coaching permitted by a designated person in qualifying and main draw matches.

Verbal coaching will be permitted when players are at the same side of the court as their coach, with non-verbal instructions – for example hand signals – allowed at any time.

Patrick Mouratoglou coached former world number one Serena Williams and now works with Simona Halep, and was quick to welcome the introduction.

Mouratoglou suggested the coaching methods have been used at "almost every match for decades".

While Mouratoglou was a vocal supporter of the ATP decision, Kyrgios – who pulled out of the Mallorca Championships with injury – hit back and slammed the proposed changes.

"Completely disagree. Loses one of the only unique traits that no other sport had," Kyrgios responded to Mouratoglou's post on Twitter.

"The player had to figure out things on his own. That was the beauty of it. What happens if a high-profile player versus a low-ranked player who doesn't have or [cannot] afford a coach?"

The trial commences on July 11 and will be evaluated at the end of the 2022 season, to assess the potential inclusion of off-court coaching in subsequent seasons.
