Nick Kyrgios has doubled down on the claim he will retire if he wins a grand slam next year, saying years of intensive travel have left him "exhausted".

Kyrgios enjoyed the best grand slam run of his career when he finished as runner-up to Novak Djokovic at Wimbledon this year, while he also reached the last eight at the US Open.

However, the Australian questioned his future in the sport earlier this week, telling reporters in Dubai: "Hopefully I can win a slam and just retire."

Speaking to Eurosport, the world number 22 insisted that remark was serious, saying his private life had suffered due to his time spent travelling to take part in ATP Tour events. 

Asked if he would really call time on his career in the event of winning a first major singles title, Kyrgios said: "Honestly, I probably would.

"Especially being from Australia as well, there's just so much travel, so much time away from family, so much time away from friends. 

"You're just missing milestones in the family, you're just not having a normal life, really. No other tennis player that's not from Australia gets that."

Kyrgios believes few athletes can match the sacrifices he has made in his career, citing the strain caused by spending long periods away from his home country. 

"It's easy for a European or an American player to lose or win a tournament, then you take a five-hour flight back home and you spend a week there before the next event," Kyrgios said.

"Whereas as an Australian, you're doing four- to seven-month travel blocks. Honestly, I don't think it's healthy. 

"No other real athlete does that in the world, in any sport, doing seven months on your own. 

"I'm exhausted honestly. It's just stressful. The more you win, the more success you have, the more demands you have off the court. People expect more from you. 

"People are like, 'why are you complaining about it?' It's not what they think. You're living out of a suitcase at hotels, it's not like you're on holiday. 

"You've got to go to tennis courts and train. The lifestyle is quite vigorous. If it happens, I probably would [retire], to be honest."

Kyrgios has only reached the last eight at the Australian Open on one occasion, and with the next edition of his home slam approaching, the 27-year-old is less than enthusiastic.

Asked if he will feel refreshed by the time the Melbourne major begins next month, Kyrgios said: "Probably not. There is a little bit of excitement, but it's probably 95 per cent stress, five per cent excitement, to be honest."

Andy Murray has conceded he is just one major injury from being forced to retire, though the three-time grand slam winner remains keen to play on.

Murray underwent two hip surgeries in 2018 and 2019, causing him to spend much of the last four years on the sidelines.

However, Murray returned to the top 50 of the world rankings after making two tour-level finals in 2022, while his run to the third round of the US Open represented his joint-best grand slam campaign since Wimbledon 2017.

The two-time Wimbledon champion saw rival Roger Federer retire from the sport in September after struggling with a knee injury, and while he acknowledges fitness concerns could force his hand, Murray is not yet looking to follow suit.

"If my body is in good shape and I'm still able to compete consistently, I'll keep playing," Murray said.

"But I can't look so far in advance with the age I'm at and with the issues I've had. If I was to have a big injury, I probably wouldn't try to come back from that."

Murray has been training with coach Ivan Lendl in a bid to ensure he enters next month's Australian Open in peak condition, having missed three of the last five editions of the tournament.

"I spent three weeks in Florida, getting my body right and getting some work done on my game and it went really well," he said.

"I'm certainly in better shape than I was. A lot of work was done in the gym, trying to build up my endurance and my stamina a bit and I'm hoping that's going to help me next year.

"I wasn't happy with how last season went – certainly the last six months or so from a physical perspective – but my ranking still went from 125 to 50 in a year. 

"I'm hoping that this year, with the work I've done, things will continue to improve and I'll still be motivated to get out there and compete."

Boris Becker described his time in prison as “the loneliest moment I've ever had” but "I believe I rediscovered the human in me" after he was released last Thursday.

Six-time grand slam singles champion Becker was sentenced to two and a half years in jail in April after being found guilty of hiding £2.5million worth of assets and loans to avoid paying debts when he was declared bankrupt in 2017.

The German reportedly spent the first few weeks of his sentence at Wandsworth Prison in London before being moved to the low-security Huntercombe prison in Oxfordshire in May.

The 55-year-old served just eight months of his sentence before being allowed out and has returned to his homeland, with reports he is not allowed back in the United Kingdom for a decade.

In an interview with Sat.1 that was broadcast on Tuesday, the tennis legend has opened up on the dark days he has experienced but says he has learned a "very expensive" lesson.

"In prison you are a nobody, you are only a number. Mine was A2923EV," he recalled when breaking his silence. "I wasn't called Boris, I was a number. And nobody gives a s*** who you are.

"When the cell door closes, the whole world collapses. This is the loneliest moment I've ever had. 

"There is only you with your thoughts. There's a carousel in your head, of course. You try to breathe calmly. I was afraid, I didn't cry.

"I believe I rediscovered the human in me, the person I once was. I've learned a hard lesson. A very expensive one. A very painful one. 

"But the whole thing has taught me something very important and worthwhile. And some things happen for a good reason."

Recalling the day of his release, Becker, who lived in London before he was sent to prison, said: "From six o'clock that morning I sat on the edge of my bed, and hoped that the cell door would open. 

"They came to get me at 7.30am, unlocked the door and asked: 'Are you ready?' I said: 'Let’s go!' I had already packed everything beforehand."

Nick Kyrgios could "just retire" if he wins a grand slam in the upcoming 2023 season.

The Australian had one of his best years yet in 2022, winning three doubles titles and also collecting the Washington Open singles final in August.

However, Kyrgios fell short again at the season's grand slams despite reaching the Wimbledon final, where he was defeated by Novak Djokovic in four sets.

With the Australian Open, Kyrgios' home tournament and first grand slam of the year, less than a month away, the 27-year-old could call it quits should he win a maiden grand slam.

Speaking between matches at an exhibition event, Kyrgios told reporters: "Hopefully I can win a Slam and just retire.

"Would I sign again? Honestly, I don't know about it.

"It took a lot of hard work this [2022] season, a lot of discipline and it seems the better you do, everyone wants a bit more of you and it becomes more stressful.

"But I had a lot of fun this season. And I’m finally just proud to say I made a Slam final and started to meet some expectations. I had a lot of fun, I enjoyed it, definitely felt better off and on the court."

It is not the first time Kyrgios has suggested an early retirement, having stated in October he will "probably not" play past the age of 30.

Rafael Nadal has made a swift appointment after long-time ally Francis Roig left his coaching team.

The record 22-time men's grand slam singles champion has brought in Argentinian Gustavo Marcaccio to work with lead coach Carlos Moya and Marc Lopez.

Nadal announced on Friday that Roig was departing, having worked with the Spaniard since 2005, to take on "a new project".

With the new ATP season just days away from beginning, Marcaccio has accepted the chance to step in, with the 45-year-old having held a position at Nadal's academy in Mallorca for the past 20 months.

Marcaccio had a mostly undistinguished playing career, reaching a high of 284th on the rankings, but he has strong coaching credentials, having worked with the likes of Juan Monaco, Svetlana Kuznetsova and Guido Pella.

Nadal wrote on Twitter: "Hello everyone. I want to inform you of the incorporation of Gustavo Marcaccio to the technical team.

"Gustavo has been working at the @rafanadalacademy since April 2021 and I understand that he is a good addition to the team. I am sure he will help us a lot to follow the path. Welcome!"

Nadal will return to Melbourne as the defending champion at the Australian Open in January, having won that and the French Open in 2022 to move ahead of Roger Federer and Novak Djokovic on the men's all-time grand slam list.

Cameron Norrie is hoping Russian players will be allowed to return to Wimbledon in 2023, saying he wants "the best players in the world to be playing".

Following the Russian invasion of Ukraine earlier this year, Russian players were banned from participating at SW19.

This meant the likes of Daniil Medvedev and Andrey Rublev were not able to play and compete for the third grand slam of the year, which Novak Djokovic ended up winning for the seventh time.

The tournament was stripped of ranking points as a result of the ban on Russians, a decision that was met with much frustration from players.

Medvedev and Rublev finished a respective seventh and eighth in the year-end ATP rankings, and both took part in the ATP Finals in Turin.

Norrie hopes they are able to return to Wimbledon next year, telling reporters: "For me, I want the best players in the world to be playing.

"I felt last year was tough for those guys, especially for Daniil and for Andrey, who have a chance of winning Wimbledon.

"I know how much those guys sacrificed with their careers and their goals are obviously very high to be winning Slams.

"So I really did feel bad for those guys."

Casper Ruud has been voted by his fellow ATP players as the winner of the Stefan Edberg Sportsmanship Award.

The 23-year-old enjoyed a fine season and sits third in the end-of-year rankings after winning three titles.

He also reached the final of the French Open, US Open and the ATP Finals, losing to Rafael Nadal, Carlos Alcaraz and Novak Djokovic respectively.

However, one title he does have is the Stefan Edberg Award, which according to the ATP's official website recognises "fair play, professionalism and integrity on and off the court".

Nadal and the now retired Roger Federer had won the award every year since 2004, with the Spaniard taking it five times – and the last four years running – and the Swiss on 13 occasions.

"A big thanks to everyone who voted for me for this year's ATP Stefan Edberg Sportsmanship Award," said Ruud.

"I feel very, very honoured and happy to win this prize this year. I will try to keep my mood in the right place for next year. Can't wait to be back on court."

Boris Becker is set to tell his story to German television on Tuesday after the tennis legend was released from prison.

The 55-year-old was sentenced to two and a half years in jail at the end of April for breaking insolvency laws.

It was news that 21-time grand slam winner Novak Djokovic, who was previously coached by Becker, said left him "heartbroken" for his close friend.

Becker, who won six singles grand slams, served just eight months of his jail sentence. It was confirmed on Thursday by his lawyer, Christian-Oliver Moser, he has returned to his native Germany, where he is not subject to any restrictions.

Now Becker is poised to speak about his experiences, shining a light on a shocking fall from grace.

The former world number one was found guilty of hiding £2.5million worth of assets and loans to avoid paying debts when he was declared bankrupt in 2017.

He will appear on the Sat.1 channel in a prime-time slot, with editor-in-chief Juliane Essling telling dwdl.de: "Boris Becker is perhaps the greatest hero of German sport. We all know the unbelievable highs and downfalls in his life. Boris Becker is familiar to us.

"Sat.1 will not talk about him – but with him. I am pleased that Boris Becker has given us his trust for the first and only interview worldwide after what may have been the most difficult time in his life."

Becker lived in London before being sent to prison but could be prevented from returning to live in the UK.

He does not have UK citizenship and the Home Office has confirmed any foreign national who is convicted of a crime and given a prison sentence is considered for deportation at the earliest opportunity.

He covered tennis in a broadcasting career before he was sentenced, being a regular presence on the BBC during Wimbledon, the tournament he won three times, including s spectacular triumph as the age of 17 in 1985.

Rafael Nadal on Friday revealed long-time coach Francis Roig is no longer on his team.

Former player Roig has been working with the legendary Spaniard since 2005, helping him win a record 22 grand slam titles.

Roig's long spell on the Nadal team has now come to an end, with the world number two announcing that his compatriot has taken on a "new project."

He wrote on social media: "I wanted to inform you that Francis Roig is leaving the team. Francis has been an important person in my career and I am very grateful to him for all these years of work and friendship.

"When we started working together I was a child and together with my uncle Toni, we started on the circuit.

"Francis is a great coach who knows tennis very well and has helped me a lot to get better and better. I only have words of gratitude and I wish him all the luck in the world in his new project."

Toni Nadal left his nephew's coaching team at the end of the 2017 season and is now working with Canadian Felix Auger-Aliassime.

Carlos Moya was appointed as Nadal's coach following Toni Nadal's departure.

Andy Murray has been named the winner of the ATP's Arthur Ashe Humanitarian Award for the second time after he donated his prize money for 2022 to Ukraine.

The Briton announced in March that his winnings earned throughout the rest of the year would be donated to UNICEF, for whom he is an ambassador.

Ukraine was invaded by neighbour Russia in February, escalating an ongoing conflict that saw players from the latter nation barred at Wimbledon this year amid sanctions.

After previously being presented with the honour in 2014, Murray revealed earnings of approximately £510,000 would be donated from his season.

"There are 7.5 million children in Ukraine and after more than nine months of increased conflict, 5.2 million of them are in need of assistance," he said. 

"When you see images of children on the news who were impacted by things like this, that makes it even more difficult to stomach.

"I have four young children who are really fortunate that everything is fine with them. But being a parent, it affects you differently.

"You try to put yourself in their shoes. If something like that happened with your own family, how difficult would that be? It is hard to fathom."

Carlos Alcaraz was meanwhile named the Most Improved Player of the Year, after the Spaniard claimed a maiden grand slam at the US Open and reached number one in the ATP Rankings.

"Everything has come so fast," the teenager added. "I didn't think at the beginning of the year that I'm going to have the year that I'm having right now.

"I always believe in my team and in my work, so this is something that came with the hard work that I put in every day. Everything pays off."

Boris Becker could be deported from the United Kingdom after the tennis legend was released from prison on Thursday.

The 55-year-old was sentenced to two-and-a-half-years in jail at the end of April for breaking insolvency laws.

Six-time grand slam champion Becker served just eight months of his sentence and it was confirmed by his lawyer, Christian-Oliver Moser, that he has returned to his native Germany - where he is subject to any restrictions.

The former world number one was found guilty of hiding £2.5million worth of assets and loans to avoid paying debts when he was declared bankrupt in 2017.

Becker reportedly started his sentence in London's Wandsworth Prison, before being moved to Huntercombe Prison in May.

He lived in London before being sent to prison but could be prevented from returning to live in the UK.

Becker does not have UK citizenship and the Home Office have confirmed any foreign national who is convicted of a crime and given a prison sentence is considered for deportation at the earliest opportunity.

He covered tennis in a broadcasting career before he was sentenced.

Nick Kyrgios will play the French Open for the first time since 2017 next year because his partner wants to visit Paris, though he would prefer to stay at home.

Kyrgios has never been beyond the third round at Roland Garros, last appearing at the event in 2017 – when he suffered a second-round defeat against Kevin Anderson.

Last year, the Australian labelled the French Open "the worst grand slam" and called for the competition to be "taken off the calendar altogether".

However, Kyrgios now says he will end his absence from the Paris event, though his reasons for doing so are not tennis related.

"My girlfriend wants to know Paris, so I'm going to play at Roland Garros 2023," Kyrgios told reporters in Saudi Arabia.

"It will be good for me to earn some more money, although I would have preferred to stay at home.

"I know I can do great results on clay. I beat Roger [Federer], [Stan] Wawrinka, I played a final in Estoril. My girl wants to get to know the city so I will have to go this year."

Kyrgios achieved two of his four best grand slam runs in 2022, losing the Wimbledon final to Novak Djokovic before exiting the US Open at the quarter-final stage against Karen Khachanov.  

Carlos Alcaraz pinpointed Iga Swiatek as a hot shot example to follow as the world number one looks to successfully defend top spot in the ATP rankings.

Spaniard Alcaraz enjoyed a hugely impressive 2022 season, winning five titles including a first grand slam at the US Open.

The 19-year-old subsequently became the youngest number one in ATP history, as well as the youngest player to top the year-end rankings.

It has also been a dominant year for Swiatek, who landed eight titles including the French Open and US Open, while also embarking on a 37-match winning streak – the longest this century on the WTA Tour – and registering 22 'bagel' sets.

Alcaraz, who knows there will be greater expectations on him delivering the goods, hopes to follow in the footsteps of the runaway WTA leader.

"I see her year has been incredible," Alcaraz told Arab News. "She broke a record for the longest winning streak [this century]. It's amazing,

"I wish to be like her, to not lose the number one [ranking]. But I think it's almost impossible. I'm going to lose it, but the point is to recover it and stay there at number one as much as I can."

He added: "Obviously yes, all the people want to beat the number one in the world. I could feel that after the US Open, everyone had a target on me and everyone wanted to face me on court. That's what I have to be prepared for."

Despite an incredible year, Alcaraz admitted his achievements are yet to truly hit home.

"It sounds like a dream for me," he said. "Honestly, there are so many times I think about this year, about my position right now, and I still can't believe it. I'm thinking: 'Is this real? I’m number one in the world?' I'm dreaming. It's something I have to realise someday."

Roger Federer swept to Wimbledon men's singles glory a record eight times, but the Swiss was almost turned away on an impromptu trip to the All England Club last month.

Having retired from professional tennis in September, Federer has more time on his hands than usual and during a visit to London he decided to pay the famous venue a visit.

Singles champions at Wimbledon become honorary members of the club, but it turns out the membership card they are given is rather important, particularly when security insist on seeing it.

Federer posted a picture of the Wimbledon trophy on social media on November 25, with the caption: "Nice to see you again."

It turns out it was quite an effort to get into the grounds before he took that snap, with Federer telling Daily Show host Trevor Noah this week how much of an ordeal it proved to be.

The 41-year-old said: "I have not really been at Wimbledon when the tournament is not on, so I drive up to the gate, where usually guests come in, where you would arrive and then you go up. I get out and tell my coach who was with me at the time, Severin, I tell him I'll quickly go out and speak to the security lady, I got this. I did not.

"So then I get out and I'm like, 'Yes, hello, I was just wondering how I can get in to Wimbledon? Where is the door? Where is the gate?'. She [says], 'Do you have a membership card?'. I'm like, 'Uh, we have one?'."

Doors usually open for Federer, a 20-time grand slam champion, but this one looked like being closed to him, despite his many past successes on the famous grass courts.

He won at Wimbledon each year from 2003 to 2007, before adding titles in 2009, 2012 and 2017. Still, it helps to have a membership card to enter a members' club, as the security official made clear.

Federer said: "I tell her normally when I'm here I'm playing and there's loads of people and I come in in a different way and it's the first time I'm here while the tournament's not on and I don't know where to get in so, 'I'm just asking you again, where can I get in?'.

"She's like, 'Well at the side, but you have to be a member'. So I look at her one last time and I'm in a panic now."

This was where Federer reluctantly played the 'don't you know who I am?' card.

"I'm so sorry, I still can't believe I said that, I still feel bad about it, and I look at her and I was like, 'I have won this tournament eight times. Please believe me, I am a member and where do I get in?'," he said.

He moved along to seek a different way in, and this was where his luck turned.

"I get out of the car and a random person walks in the walkway and said, 'Oh Mr Federer, I can't believe you're here at Wimbledon! Can we take a selfie?'," Federer said.

"I'm like, 'Yes! Let's take a picture!'. And the security guards that are there are like, 'Oh my God, Mr Federer, what are you doing here? Do you have your membership card?'."

Federer did not. This time, however, his luck was in.

"I'm like, 'No I don't, but is it possible to get in?'," he said. "[And they said] 'Of course we'll open the door, let me organise it'."

Although he was unable to play due to injury, Federer made a fleeting appearance at Wimbledon in 2022 at a line-up of champions to mark 100 years of Centre Court.

Nick Kyrgios admits the pressure he is facing is "a lot to handle", as he prepares for next month's Australian Open.

Having started 2022 with a doubles title with Thanasi Kokkinakis at his home grand slam, Kyrgios then advanced to the final of Wimbledon and suffered defeat at the hands of Novak Djokovic.

That form, which also saw him reach the quarter-finals at the US Open, has put the 27-year-old in the conversation as a title contender for the 2023 grand slams, the first of which begins in Melbourne on January 16.

Kyrgios is aware there are great expectations for him in the year ahead and conceded it is not easy being in the spotlight, particularly ahead of his home grand slam.

"I always believe that pressure is a privilege. In real life, there's not much pressure to being a professional tennis player," he told Eurosport.

"We earn great money, we travel around the world with our favourite people. We get to see different people, different cultures.

"In the scheme of things, that's not pressure but I completely understand going on the match court with all this expectation that 'Nick Kyrgios is legitimate chance to win a grand slam now'.

"There's a lot of pressure there, especially having the Australian Open and everyone in Australia expecting big things from me. It's a lot to handle sometimes. Being in the spotlight is not easy."

The last Australian man to win a singles grand slam title was Lleyton Hewitt in 2002 at Wimbledon, while the wait for men's success at home goes back further to 1976 – when Mark Edmondson was victorious in Melbourne.

While there is a desire for Kyrgios to end those lengthy waits, he has made it clear he wants the success for his own goals, not for anyone else.

"I've learnt that the people will never have enough. For me, I've achieved some great things in this sport and where I came from," he said.

"I know I'm content with myself. I want to achieve more for myself, but for all of my team, not for anyone else."
