Gilles Simon believes Andy Murray's inferior trophy haul means he cannot be grouped with tennis' 'Big Three' of Novak Djokovic, Rafael Nadal and Roger Federer.

Murray has enjoyed a long and stellar career, reaching 11 major finals and claiming three grand slam titles, as well as spending 41 weeks ranked as the world number one.

But with Djokovic, Nadal and Federer boasting 23, 22 and 20 grand slam successes respectively, Simon feels Murray is not quite on their level.

"He's not part of the Big Three," Simon told Stats Perform at the Roland-Garros eSeries by BNP Paribas. 

"You don't have to compare him with the Big Three, because he played at the very same time and we have the result.

"Andy was a fantastic player, just under these three guys in terms of level. In the end, the gap is huge in terms of titles: 23, 22 and 20, compared to three, so he's not part of the Big Four.

"He played at the same time as everyone and he has three and they have 20 or more. That's how I see it."

Simon – who won three of his 19 meetings with Murray before retiring in 2022 – feels the Scot was unfortunate to have competed with the 'Big Three' and would have been remembered as one of the game's greats in another era.

"He could have won 17 slams without the Big Three," Simon explained. "What is hard for Andy is to compare him to other players from other generations, when other players maybe have more slams than he has.

"If he had played at that time, he could maybe have had 15 and been one of the greatest. You cannot compare him with the Big Three, we saw it already, we saw the results.

"Where I feel sad for Andy is that if you play in a different era, you have 10 [grand slam titles] and then if we take the all-time rankings, we go to [Pete] Sampras with 14 and you say maybe he's here.

"This is where I feel it's a bit of an injustice for him compared to his level, because he would be closer to something like this than to someone who has three slams. He would be much higher in the all-time rankings."

Iga Swiatek could end her French Open career with a record to rival Rafael Nadal’s, tournament director Amelie Mauresmo believes.

The Pole cemented her status as one of the best women’s players on clay in recent decades by winning her third title in four years just after her 22nd birthday.

That matches the career progression of Nadal almost to the day, although Swiatek has one US Open title while the Spaniard won on his first four visits to Roland Garros.

“Her record is very impressive, just like Rafa’s record was when he started,” said former world number one Mauresmo.

“Three titles in four editions is huge, it’s very impressive. I think we’re still a little bit far away from the 14 titles but, when Rafa started, no-one also thought he would get to 14 so anything can happen.”

Swiatek found herself really tested for the first time in a grand slam final, twice coming from a break down in the deciding set to beat Karolina Muchova 6-2 5-7 6-4.

She is not looking too far ahead, saying: “I’m just happy with what happened during these past few weeks. I don’t know what I’m capable of.

“So I will work day by day to play the best game possible and to develop as a player. I’m not setting any crazy records or goals for myself. I know that keeping it cool is the best way to do it for me. I’m trying more to do that.”

Swiatek has not had things all her own way this season, with a couple of injuries disrupting her schedule, while Aryna Sabalenka and Elena Rybakina have raised their game to create what has been described as a big three of women’s tennis.

Sabalenka could have overtaken Swiatek in the rankings in Paris, and the Belarusian will have high hopes of doing so on the grass, where she has been much stronger than her rival in the past.

Swiatek did not shy away from talking herself up in comparison to Sabalenka and Rybakina, saying: “I look at my clay-court season and I see on every tournament I really played consistently.

“I reached quarter-finals, semi-finals, finals, I won Stuttgart, I won this tournament. I’m just focused on myself and I don’t care about the other two players.”

For Muchova, it was a bitter-sweet experience, with the Czech handling herself extremely well in her first grand slam final but falling short when the match looked like it was almost in her grasp.

What will give a lot of confidence to the 26-year-old, who will be ranked at a career-high 16 on Monday, is that clay is her least favourite surface.

“I wouldn’t expect it that much on the clay, honestly,” she said. “I look forward to playing on the grass, on the fast surfaces. It’s just nice to know that I can play on the clay great as well.

“This was my last clay tournament. It could have ended up a little bit better, but it was still pretty great.”

It was one of the best endings to a women’s grand slam in recent years, with both semi-finals bringing high quality and drama before a very good final.

There has been a lot of focus again in Paris on the scheduling, with the one-match night session featuring women only once for the second year in a row.

Mauresmo defended the decision-making, insisting other slots considered prime time featured more women’s matches this year.

Organisers do not want matches finishing in the early hours of the morning like they routinely do at the Australian Open and US Open, and Mauresmo admitted the possibility of a quick two-set women’s contest is a key factor in favouring men.

Swiatek, meanwhile, revealed she prefers playing in the day and had requested not to play at night.

“This doesn’t make also our life easier,” said Mauresmo. “I’m comfortable with the scheduling in the day but, yes, we can do better on the night matches.”

Rafael Nadal underwent surgery on Friday evening in a bid to discover the extent of his hip problem.

The 22-time grand slam champion only expected to be out for six to eight weeks with the injury he suffered at the Australian Open in January but nearly five months on he has not recovered.

Nadal was forced to miss the French Open for the first time in nearly two decades having admitted his team had not been able to find a solution to the issue.

The Spaniard, who turns 37 on Saturday, announced last month that he would be taking a break, potentially for the rest of the season, before what he expects to be farewell tour next year.

Nadal’s representatives revealed the surgical intervention on Friday, with the 14-time French Open champion undergoing an arthroscopic investigation on his left psoas muscle in Barcelona.

The results are expected to be announced on Saturday morning.

International Tennis Federation (ITF) president David Haggerty is disappointed that Rafael Nadal will not be able to feature at Roland Garros, which he called "Rafa's house".

Nadal has not played since suffering a second-round exit at the Australian Open in January, having struggled with a hip injury during his straight-sets defeat to Mackenzie McDonald, and will not play at the French Open.

The Spaniard last week confirmed he will be unable to compete at Roland Garros, where he is a record 14-time champion.

When announcing his withdrawal, Nadal said 2024 would "probably" be his final year on the ATP Tour and outlined his intention of making farewell appearances at "important tournaments".

Haggerty said: "I think it's disappointing for Rafa not to be there because we know Roland Garros as Rafa's house so to speak.

"He's won it so many times and people love to watch him play. [It is] disappointing.

"I was happy to hear that he is talking about the possibility of his return to the Davis Cup finals, which would be fantastic. I wish him a successful recovery and hope to see him on the court again."

While Nadal will not be present in Paris, WTA world number one Iga Swiatek is set to be in action.

Swiatek is the defending champion, and Haggerty says the Pole will be well aware her rivals are gunning for her title.

"She's the number one player in the world and I think that she has been ranked number one for more than a year consecutively," he said.

"So [she is] a very, very good player. She won Roland Garros last year, so I expect to see her performances continued to be good knowing that everybody's after her to try to beat number one."

At 21, Swiatek already has three grand slam titles under her belt. And with 20-year-old Carlos Alcaraz conquering all on the ATP Tour, Haggerty thinks tennis' future is in safe hands, even as Nadal and Novak Djokovic reach the twilight of their careers.

"I think we have many good young men and young women that are showing how great tennis is and and putting on good rivalries already," he said. 

"So I think the future is bright."

Rafael Nadal will be contemplating the best way to call time on his stellar career after injury denied him the chance to defend his French Open title, believes Tommy Haas.

Nadal has not played since suffering a second-round exit at the Australian Open in January, having struggled with a hip injury during his straight-sets defeat to Mackenzie McDonald.

The 22-time grand slam champion last week admitted defeat in his bid to appear at Roland Garros, where he has triumphed 14 times – a record for any player at a single grand slam.

When announcing his withdrawal, Nadal said 2024 would "probably" be his final year on the ATP tour and outlined his intention of making farewell appearances at "important tournaments".

Nadal's long-time rival Roger Federer retired surrounded by several of his fellow greats at last year's Laver Cup, and Haas believes the Spaniard will be eyeing a similar send-off. 

"At some point, time catches up with all of us and that's the reality," Haas, a four-time grand slam semi-finalist, told Stats Perform.

"I think at this stage, I'm sure he's been contemplating the idea: 'When would I do it? How would I do it? How would it come together organically?' 

"We saw Roger Federer doing it last year and the way he was able to retire in London at the Laver Cup with all of his rivals and friends on the court. I happened to be there live, it was an amazing way to finish such an incredible career. 

"Look at Pete Sampras. He won his first slam at the US Open and he won his last match at the US Open, winning the slam there on home turf – there couldn't have been a better fairy tale. 

"I think you look at that and at the same time, you have to stay focused on what's happening today and you can't look too far ahead."

Though Nadal's total of 22 grand slam singles titles is a joint record in the men's game (alongside Novak Djokovic), the Spaniard's injury record has denied him several chances to add to that tally.

Nadal played all four grand slams for the first time since 2019 last year but was forced to withdraw from the Wimbledon semi-finals, and Haas says the Spaniard's fitness will dictate his future.   

"It always depends, obviously, on the injuries. 'How bad is it and can I recover from it?' I'm sure Rafa is constantly thinking about those situations," Haas added.

"He's been saying he still wants to play for another year or two, which would obviously be amazing for the sport. 

"On clay, I think he has a better chance of keeping the body in a better shape than on gruelling hardcourts. He obviously plays long matches, which is tough on the body."

The main draw of the French Open begins on Sunday, with Nadal's compatriot Carlos Alcaraz the top male seed as he bids for a second major title.

Rafael Nadal admitted he is staring at the end of his tennis career after announcing he will miss the French Open and the majority of the season ahead of what he expects to be a farewell tour in 2024.

The 22-time grand-slam champion has not played since his second-round exit at the Australian Open in January.

Nadal struggled with a hip injury during the straight-sets defeat to Mackenzie McDonald and the ongoing issue has failed to recover sufficiently in order for the 36-year-old to chase a 15th title at Roland Garros.

It means the Spaniard, who has only lost three matches on the Parisian clay, will miss the tournament for the first time since 2004 but he admitted during a press conference at his academy in Manacor that it feels the only option.

The 14-time French Open champion now plans to rest for the coming months with the aim to recover so he can play at “important tournaments” in 2024 during what will be his final year on the ATP Tour.

“My goal and my ambition is to try and stop and give myself an opportunity to enjoy the next year that will probably be my last year in the professional tour,” Nadal told reporters.

“That is my idea but I can’t say 100 per cent it will be like this, but my idea and my motivation is to try to enjoy and say goodbye to all the tournaments that have been important for me.

“To enjoy being competitive and something that today is not possible. I believe, if I keep going now, I will not be able to make it happen.”

On next week’s French Open, Nadal explained: “First thing, I’m not going to be able to play in Roland Garros.

“I was even working as much as possible every single day for the last four months, they have been very difficult months because we were not able to find a solution to the problems I had in Australia.

“Today I’m still in a position where I am not able to feel myself ready to compete at the standards I need to be to play Roland Garros.

“I am not the guy who will be at Roland Garros just to play.”

Nadal claimed brilliant victories at the Australian Open and French Open last year but was fighting his body, with a chronic foot problem, fractured rib and an abdominal strain that forced him out of Wimbledon keeping him off the court for spells prior to this latest injury.

His withdrawal from the French Open had appeared increasingly inevitable but the news he will also sit out Wimbledon, and almost certainly the US Open as well, is a major blow to the sport, which must now prepare to say goodbye to the Spaniard having seen his great rival Roger Federer bow out last autumn.

Nadal suggested he might try to turn out for Spain at the Davis Cup later this year, while a major target in 2024 will be the Olympic Games in Paris, with the tennis events being played at Roland Garros next summer.

“After a couple of years that in terms of results have been positive because I was able to win a couple of grand slams and important tournaments, the real situation is I was not able to enjoy my diary work,” Nadal said.

“Since after the pandemic, my body was not able to do the practice or diary work in a good way so I was not able to enjoy the practice and competition because too many problems, too many times having to stop for physical conditions and too many days off not practising because of too much pain.

“I need to stop for a while. My position is to stop and I don’t know when I can come back to the practice court.

“I will stop for a while, maybe one month, maybe two months, maybe three months. I am a guy who doesn’t like to predict too much the future. I am following what I believe is the right thing to do for my body and my personal happiness.

“I don’t want to say one thing and do the other. It is better to hold the options open and see what is the best calendar possible.

“I would like to play the things that are important for me and of course the Olympic Games is an important competition and one I hope to play. Will it be my last or not? I cannot say.”

Nadal’s compatriot Carlos Alcaraz, who will be the top seed for the French Open, sent his best wishes on Twitter, saying: “Good luck Rafael! Very painful and sad for everyone that you can’t be at Roland Garros or play more this year, but I hope that 2024 will be a great season for you and that you can say goodbye like the great champion you are.”

Alcaraz will now lead the favourites at Roland Garros along with Novak Djokovic, who can claim the outright men’s record for slam singles titles if he wins a 23rd.

Speaking on Amazon Prime Video, former British number one Tim Henman said: “I think the real positive is that he is prepared to give it one last effort, and that’s what Rafa’s always been about, giving 100 per cent to everything he’s doing.

“And fingers crossed he can find that physical wellbeing to be back out on tour. If 2024 is his last year then I really hope that he can enjoy it and I hope we can enjoy it and the fans can enjoy it because he deserves that send-off.”

Rafael Nadal will be absent from next week’s French Open and has signalled his intention to retire in 2024.

The 22-time grand-slam champion has not played since his second-round exit at the Australian Open in January.

Nadal struggled with a hip injury during the straight sets defeat to Mackenzie McDonald and the ongoing issue has failed to recover sufficiently in order for the 36-year-old to feature at Roland Garros.

It means the Spaniard will miss the tournament for the first time since 2004 but he admitted during a press conference at his academy in Manacor that it feels the only option to prolong his career.

The 14-time French Open champion now plans to rest for the coming months with the aim to recover so he can play at “important tournaments” in 2024 during what will be his final year on the ATP Tour.

“My goal and my ambition is to try and stop and give myself an opportunity to enjoy the next year that will probably be my last year in the professional tour,” Nadal told a press conference.

“That is my idea but I can’t say 100 per cent it will be like this but my idea and my motivation is to try to enjoy and say goodbye to all the tournaments that have been important for me.

“To enjoy being competitive and something that today is not possible. I believe if I keep going now, I will not be able to make it happen.”

On next week’s French Open, Nadal explained: “First thing I’m not going to be able to play in Roland Garros.

“I was even working as much as possible every single day for the last four months, they have been very difficult months because we were not able to find a solution to the problems I had in Australia.

“Today I’m still in a position where I am not able to feel myself ready to compete at the standards I need to be to play Roland Garros.

“I am not the guy who will be at Roland Garros just to play.”

Rafael Nadal missing the French Open this year would be a huge disappointment, though Emmanuel Cruze would prefer to look on the bright side.

Cruze is the head of the Villa Primrose Club, the host of the Bordeaux Challenger event, which Nadal declined an invitation to as he continues his recovery from injury.

The 36-year-old has not played since going out in the second round of the Australian Open in January.

Nadal has since dropped to 14th in the ATP rankings, and it is not yet clear if he will be fit to feature at Roland Garros, where he won a record-extending 14th French Open title last year.

However, Cruze told Stats Perform that while it would be sad to see Nadal miss the season's second major, it might signal a changing of the guard in Paris.

"We would all be very disappointed for the tournament, but maybe it will be a new era that will open for all the players, and especially you are talking about Spanish players," said Cruze.

"We need to keep in mind that [Carlos] Alcaraz is really performing extremely well, and is still very young also.

"Is he the future Nadal? We don't know, but definitely if Nadal is not playing at the French Open, it will be much more open for all other players.

"[It will be exciting] for the tournament itself, because if he's there and in good shape, people will say 'Okay, Nadal will win another title, and it's going to be boring'.

"We are not sure that he will be able to play the French Open and then for the next generation it's really something that will be very important for them, to be able to play the French without the pressure of Nadal."

Cruze is unsure if Nadal would be among the favourites even if he mustered a comeback in time for the tournament, which begins on May 29.

"He is over 30 and it's always more and more difficult to come back after a major injury, we have seen with [Roger] Federer, he wants to try to come back and win Wimbledon for the last time and finally was unable to do so because when you are out for six months and you are over 30, I think it's really difficult," he said.

"But [Nadal] is such a character and such a fantastic player [that] you never know. You never know. I'm not a doctor, I'm in the wine business so nothing to do with that, even if wine sometimes helps!"

As for Nadal's legacy in France, Cruze believes there should be a permanent tribute to the 22-time grand slam champion at Roland Garros.

"I think as soon as Nadal retires, he almost deserves a statue, because he is a legend," Cruze added.

"How could you imagine winning 14 times at the French Open, which probably is one of the most difficult [surfaces] because you're playing on clay courts, you spend sometimes three or four hours on the court, which is not the same on grass or on hard courts, so I think for French tennis lovers, he will be a legend for years.

"He's a legend, but normally with a legend, it is because you stopped your career, but he is already a legend, even if he is still playing."

Looking to the future, Cruze sees Nadal's compatriot Alcaraz as a possible heir apparent.

"I've never seen him physically, only on TV and that's it, but he's a very young guy and is performing extremely well," Cruze said of the world number two.

"I don't know about on grass, but for hard courts, he seems to be fine, so if he's fine with a hard court, he would normally be a good player on grass, so yeah he could be the next legend, why not? But so far the real [legend] is still Rafael Nadal, up until he retires."

Boris Becker believes Novak Djokovic can secure a record-breaking triumph at the French Open, where the tennis great hopes Rafael Nadal will return to action.

Djokovic moved level with Nadal for the most grand slam singles titles among male players after clinching his 22nd major with January's success at the Australian Open.

The Serbian will have his sights on a landmark 23rd major triumph at Roland Garros, where the tournament starts on May 28, and Becker sees no reason for Djokovic not to break the record in Paris.

Former world number one Becker, a six-time major winner, told Stats Perform: "Do I believe Novak can win 23? Absolutely, I can.

"But it's not easy. Competition doesn't sleep."

Djokovic has made light work of said competition in recent years, though a return for 14-time French Open winner Nadal would throw the upcoming major wide open.

However, the Spaniard has not featured since sustaining a hip injury at the Australian Open in January, most recently pulling out of the Italian Open as he had not fully recovered.

"The question is Nadal, can he come back? Can he play in the French Open? I personally hope so," Becker added.

"I think tennis needs Nadal. We need him. And so hopefully he comes back and plays as a 14-time winner of Roland Garros.

"But Novak is healthy, he's fit. He wants to play so he's one of the favourites."

Carlos Alcaraz wishes to build his "own history" rather than "take over" from fellow Spaniard Rafael Nadal, having won the ninth title of his career at last week's Barcelona Open.

Alcaraz defended his crown in Catalonia by racing to a 6-3 6-4 win against Stefanos Tsitsipas in Sunday's final, claiming his third title of the 2023 season. 

Like his legendary compatriot Nadal, Alcaraz won his first grand slam title at the age of 19, triumphing at the US Open last year.

His hopes of adding to that success at the upcoming French Open could be boosted by the misfortune of his rivals, with both Nadal and Novak Djokovic forced to withdraw from this week's Madrid Open as they battle injuries.

While comparisons between Alcaraz and Nadal are perhaps inevitable, the teenager is determined to do things his own way.

"As I've said on more than one occasion, I don't want to take over from anyone," he said after claiming his latest title. 

"I feel lucky to have so many people supporting me, transmitting that positive energy from the first game.

"Speaking of this week, it's been two years that Rafa hasn't been there [in Barcelona]. I've been lucky! But as I've always said, I've always wanted to play against the best.

"It is a pity that we have not been able to enjoy Rafa these last two years. Let's hope he continues playing for a long time and we can enjoy his tennis, but obviously we're not here to take over from anyone, but to build our own history."

With Nadal and Djokovic absent, Alcaraz will be the top seed as he looks to add a 10th career title in Madrid, but he does not see winning in the Spanish capital as the only measure of a successful campaign. 

"Not winning Madrid would not be a failure for me, it depends on the level I have shown and the matches," he said.

"All the players are very good, they can all win the title and they can beat me. For me, failure would depend on the level I show and the way I play."

French Open tournament director Amelie Mauresmo feels it is "hard to imagine" the tournament without Rafael Nadal, with the 14-time champion's participation at Roland Garros in doubt.

The most successful player in the history of the season's second grand slam, Nadal has not played since his second-round exit at the Australian Open in January due to a hip injury.

The 22-time major winner recently withdrew from the upcoming Madrid Open, and is now facing a race to be fit in time for the French Open, which begins in a little over five weeks' time.

Nadal is an ever-present at Roland Garros since winning his first title in 2005, and Mauresmo hopes that continues to be the case.

"It's obviously a possibility for him not to be able to be fit to come here to Roland Garros," the two-time grand slam winner told BBC Sport on Court Philippe Chatrier.

"But the only thing I know for sure is that if there is one tournament he doesn't want to miss, it is this one. We are still five weeks away from the main draw. I am still hopeful, and I'll keep my fingers crossed.

"It will be hard [to imagine Roland Garros without him]. It would be hard if he doesn't come, to be honest.

"He's so much part of the history of the tournament for the last almost 20 years – it would be sad. But I am someone that is positive, so I'm going to hope that things are going to get better for him."

Nadal's exploits at the French Open were recognised when a statue was erected outside the general public entrance and the Jardin des Mousquetaires at Roland Garros.

Mauresmo also revealed discussions are ongoing regarding an alternative way to commemorate his achievements in the French capital.

"The opinions are very different with everyone," she added. "I think it would be hard to change the name of this [Philippe Chatrier] court, but, yes, we are having these conversations sometimes.

"We will need to do something to [celebrate] 14 – maybe more one day. It is just something that is incredibly crazy, and in the history of sport quite unique."

Rafael Nadal remains unsure when he will return to action with the French Open looming after being forced to withdraw from the Madrid Open.

The 22-time grand slam champion has been struggling with a left hip issue that contributed to his second-round exit at the Australian Open in January.

Nadal pulled out of the Indian Wells Open and Miami Open, while the troublesome injury has also hampered the start of his favoured clay-court season.

Having withdrawn from the Monte Carlo Masters and Barcelona Open, the Spaniard is still not fit enough to participate in next week's Madrid Open on home soil.

And a concerned Nadal is now facing a race to be fit in time for the French Open, which begins in a little over five weeks' time.

"As you know, I suffered an important injury in Australia of the psoas [muscle]," he said in a video published on social media on Thursday.

"Initially it had to be a six-to-eight-week recovery period and we are now on fourteen. The reality is that the situation is not what we would have expected.

"All medical indications have been followed, but somehow the evolution has not been what they initially told us and we find ourselves in a difficult situation.

"The weeks are passing and I had the illusion of playing in tournaments that are the most important in my career, like Monte Carlo, Barcelona, ​​Madrid, Rome, Roland Garros. 

"For the moment, I have missed Monte Carlo and Barcelona. I will not be able to be in Madrid, unfortunately."

Nadal, who has played just four matches this season, added: "The injury still hasn't healed and I can't work out what I need to to compete. 

"I was training, but now a few days ago we decided to change course a bit, do another treatment and see if things improve to try to get to what comes next.

"I can't give deadlines because if I knew I would tell you but I don't know. This is how things are now."

Nadal won a record-extending 14th French Open title with a straight-sets victory over Casper Ruud in last year's final.

Rafael Nadal will not play at next week's Barcelona Open as he waits to return from a hip injury.

The 22-time grand slam winner has not played since going out to Mackenzie McDonald in the second round of the Australian Open in January.

Nadal did not feature at tournaments in Indian Wells or Monte Carlo, and his latest withdrawal casts further doubt on his participation at the French Open, which begins at the end of May.

He wrote on Instagram on Friday: "Barcelona is a special tournament for me, because it's my adopted club and because playing at home is always a unique feeling.

"I'm still not prepared and therefore I'm still in my preparation process for the return to competition.

"Good luck to my friend [tournament director] David Ferrer and his whole team for this edition of the Godo that will surely be a success as always on all levels."

Nadal is a 12-time winner of the Barcelona Open, which he last won in 2021.

The 36-year-old recently dropped out of the world's top 10 men's rankings for the first time since 2005 due to his injury absence, and he currently sits in 15th place.

Rafael Nadal has confirmed he will not be competing at the Monte Carlo Masters.

Nadal, who has won 11 times in Monte Carlo, had been hoping to make his return from a hip injury at the ATP Masters 1000 event, which starts next week.

The 36-year-old has not played since going out to Mackenzie McDonald in the second round of the Australian Open in January.

Nadal previously cast doubt on his status for Monte Carlo last month, and on Tuesday he announced he will be unable to participate.

"Hi everyone, I'm still not ready to compete at the highest level," Nadal tweeted.

"I will not be able to play in one of the most important tournaments of my career, Monte Carlo.

"I am not yet in a position to play with the maximum guarantees and I continue my preparation process, hoping to return soon."

Nadal's latest setback is another blow in his preparations for the French Open, which starts at the end of May.

The Spaniard, who dominated in Monte Carlo between 2005 and 2012, has slipped down to number 14 in the ATP world rankings.

Rafael Nadal has cast doubt on a possible return at next month's Monte Carlo Masters after revealing he is still unsure when he will be ready to make his comeback.

The 22-time grand slam champion has been struggling with a left hip issue that contributed to his second-round exit at the Australian Open in January.

Nadal pulled out of hard-court contests at the Indian Wells Open and Miami Open as he continued to recover from the problem.

Speaking two weeks ago, Monte Carlo Masters director David Massey said Nadal was the first player to register for this year's Masters 1000 event, which begins on April 8.

The tournament's official Twitter account more recently suggested Nadal will "definitely" take part.

However, Nadal – who has slipped out of the world's top 10 men's tennis rankings for the first time in almost 18 years – denied that is the case.

"I don't know who gets this information," he is quoted as saying by Spanish publication Marca.

"Obviously if it were true, I would confirm it, but unfortunately I can't. I'm following my course and I don't know when I'll play again, that's the truth.

"I'm in a phase of increasing work. If I knew when I was going to return, I would say so, but I don't know.

"I can't confirm that I will play in Monte Carlo. Things are seen day by day. I prefer to say things when I really know them."

The Monte Carlo Masters kicks off the clay-court season ahead of events in Madrid and Rome, with the French Open – Nadal's favourite event – now just two months away.

Nadal has won the Monte Carlo Masters a record 11 times, though his most recent triumph came in 2018 with victory over Kei Nishikori in the final.
