Rafael Nadal declared it was imperative to "follow the rules" on COVID-19 vaccinations after rival Novak Djokovic was told he faces being deported from Australia.

World number one Djokovic was left fighting for the right to compete at the Australian Open, a tournament he has won nine times, after authorities cancelled his visa.

A medical exemption was expected to allow Djokovic to enter the country, regardless of his vaccination status, which he has yet to formally disclose.

However, the Australian Border Force declared the Serbian had been ordered to fly out of the country on Thursday, sparking a challenge to that decision by Djokovic's legal team.

Reports in Australia said an interim injunction had been granted, meaning Djokovic will remain in immigration detention until a court hearing on Monday.

According to Nadal, who had COVID-19 recently but has been cleared to compete at Melbourne Park, Djokovic would have made his life a lot easier by going down the vaccination route.

"It's normal that the people here in Australia get very frustrated with the case because they have been going through a lot of very hard lockdowns, and a lot of people were not able to come back home," Nadal said.

"The only thing that I can say is I believe in what the people who know about medicine says, and if the people say that we need to get vaccinated, we need to get the vaccine.

"I went through COVID. I have been vaccinated twice. If you do this, you don't have any problem to play here. The world in my opinion has been suffering enough to not follow the rules.

"I think if he wanted, he would be playing here in Australia without a problem. He made his own decisions, and everybody is free to take their own decisions, but then there are some consequences."

Djokovic was initially detained at an airport after arriving in Australia, while his status remained in limbo. His coach, Goran Ivanisevic, said it had been "not the most usual trip Down Under".

Spanish superstar Nadal has 20 grand slam titles, the same number that Djokovic and Roger Federer have brought up across their careers. They are locked in a race to finish with the most majors, and Federer, at 40, is battling back from injury and unlikely to compete at a slam before the US Open.

Australia's Prime Minister Scott Morrison tweeted on Thursday: "Mr Djokovic's visa has been cancelled. Rules are rules, especially when it comes to our borders.

"No one is above these rules. Our strong border policies have been critical to Australia having one of the lowest death rates in the world from COVID, we are continuing to be vigilant."

Nadal has some sympathy for Djokovic, but it appears to be limited.

"Of course, I don't like the situation that is happening," Nadal said. "In some way I feel sorry for him. But at the same time, he knew the conditions since a lot of months ago, so he makes his own decision."

Ricardas Berankis will face Rafael Nadal in the second round of the Melbourne Summer Set after beating Marcos Giron on Wednesday.

Nadal made his return after a five-month absence due to injury when he and fellow Spaniard Jaume Munar beat Sebastian Baez and Tomas Martin Etcheverry 6-3 3-6 10-4 in a doubles match in Melbourne on Tuesday.

The 20-time grand slam champion will be back in singles action against Berankis at Rod Laver Arena on Thursday after the Lithuanian qualifier dispatched American Giron 7-5 6-4.

Fifth seed Benoit Paire was trailing 4-6 6-3 5-2 to Henri Laaksonen when the Frenchman retired from the contest.

Alexei Popyrin and Jordan Thompson advanced on home soil, beating Stefano Travaglia 7-6 (7-5) 6-3 and Christopher O'Connell 1-6 7-5 6-4 respectively.

Munar beat towering South African Kevin Anderson 6-4 6-4, while Emil Ruusuvuori, Alex Molcan and Maxime Cressy also made it through.

Marin Cilic racked up the 550th victory of his career at the Adelaide International 1, defeating Thiago Monteiro 6-4, 7-6 (7-3).

Third seed Cilic will now come up against Laslo Djere, who was level at one set apiece with Corentin Moutet when the Frenchman was disqualified after reportedly swearing at the umpire.

Thanasi Kokkinakis fought back to oust Frances Tiafoe in the final match of the day, the Australian wild card winning 3-6 7-5 6-1.

Andy Murray stumbled out of the Melbourne Summer Set tournament after a first-round defeat to Argentinian Facundo Bagnis.

In his opening ATP Tour match of the year, three-time grand slam winner Murray slipped up 6-3 5-7 6-3 against Bagnis, a player who began the year with a 30-59 win-loss career record.

Left-hander Bagnis rose to the occasion on Rod Laver Arena to earn the scalp of the former world number one.

Murray, down at 134th in the rankings after another injury-hit year, is looking to make headway on that front in 2022 under new coach Jan de Witt, so that he can avoid having to take wildcards into tournaments.

He was allowed into this tournament by that back-door route, and has also been confirmed for an Australian Open wildcard, but the Scot could not find the form that saw him beat Rafael Nadal at an exhibition event in Abu Dhabi in late December.

Bagnis said of his win: "In the beginning it was a pleasure to play against Andy and right now to beat him is amazing. I'm really happy."

He added, according to the tournament website: "Yesterday, I came to see the stadium, to see it all around because the atmosphere is different when you play on any court outside… I enjoyed it a lot. It was so good for me."

Nadal was also back in action on Tuesday, playing his first match on the main tour since August as he teamed up with fellow Spaniard Jaume Munar for a doubles win.

A foot injury meant Nadal's 2021 season ended early, but he warmed up for singles tests that lie ahead by joining Munar for a 6-3 3-6 10-4 win over Argentinians Sebastian Baez and Tomas Martin Etcheverry.

At the Adelaide International 1 tournament, there was a notable first-round win on Tuesday for Australian Thanasi Kokkinakis, who saw off compatriot John Millman 6-4 6-3.

Kokkinakis, a major talent as a youngster, is battling to reassert himself on tour after injury troubles, and beating Millman put his name up in lights for at least one day.

He reflected afterwards on the battle it has taken so far, with last year spent largely living out of a suitcase on the second-tier Challenger Tour.

"It was a gruelling year travelling," said Kokkinakis. "I've played a couple of times [in Adelaide] but just in exhibitions, so to play a real meaningful tournament and beat such a quality opponent, a proven veteran like Johnny, means a lot. I played great, and the support was great, so I'm really happy."

Australian Open chief Craig Tiley wants Novak Djokovic to participate in Melbourne but will not ask the world number one to disclose any medical reason he has for being unvaccinated against COVID-19.

The first grand slam of 2022 begins on January 17, but it is unclear if reigning champion Djokovic will be competing.

The Serbian, a nine-time Australian Open winner, is yet to disclose his vaccination status.

Following guidance from the Victoria state government, all players, staff and spectators at Melbourne Park must have been fully vaccinated against coronavirus or hold a medical exemption.

Djokovic has been named on the list for the draw and is also due to represent Serbia at the ATP Cup in Sydney, which runs from January 1 to 9.

"If Novak shows up, he'll be vaccinated or have a medical exemption," Australian Open chief executive Tiley told the Australian Associated Press.

"If any player, fan [or] workforce is on site here, you're either vaccinated or you have a medical exemption that's approved and you're on the Australian Immunisation Register.

"That provides us with safety and an extra level of comfort on site.

"We want to have the best players here; I'd love to have Novak here. If he meets those conditions then great, if not, it's disappointing."

Tiley added he does not expect Djokovic to reveal any medical reason for which he may not have received the vaccine, should he receive a medical exemption to feature in the tournament.

"Medically, he doesn't talk to anyone about it. I'm not going to ask Novak that, it's none of my business," Tiley continued.

"[It's] his choice on his medical condition, it's his choice to keep personal and private like all of us would do with any condition we may or may not have. We are not going to force him or ask him to disclose that.

"[If he is here] I will know that he fulfils one of those conditions."

Rafael Nadal is set to play in Melbourne, though that is in doubt after the Spaniard tested positive for COVID-19 this week, following his appearance at the Mubadala World Tennis Championship in Dubai.

Tiley, however, believes Nadal will have recovered in time.

"I'm confident Rafa will be here," said Tiley. "Players that are testing positive now will complete a period of time until they are no longer infectious and they will be fine.

"If you are going to test positive and you want to play the Australian Open, your timing would be now."

Tokyo Olympics gold medalist Belinda Bencic has tested positive for COVID-19 ahead of next month's Australian Open and is experiencing "severe" symptoms.

World number 23 Bencic returned a positive test, along with Ons Jabeur, after competing at the Mubadala World Tennis Championship in Abu Dhabi.

The pair are the third and fourth players to have tested positive after travelling to the Abu Dhabi event, following 2021 US Open winner Emma Raducanu and 20-time major winner Rafael Nadal.

Bencic wrote on Twitter: "Unfortunately and even though I am fully vaccinated, I recently tested positive for Covid-19.

"I am currently isolating and taking all precautionary [measures] to get through this as best as possible as I am experiencing quite severe symptoms (fever, aches, chills)."

The Mubadala World Tennis Championship typically serves as a warm-up event prior to the Australian Open which is due to begin on January 17 in Melbourne.

World number 10 Jabeur, who defeated Bencic in Abu Dhabi, is experiencing "strong symptoms" and isolating in her native Tunisia.

Rafael Nadal has tested positive for coronavirus on his return to Spain, leaving his participation at the Australian Open in doubt.

The 20-time major champion played at the Mubadala Tennis Championship in Abu Dhabi last weekend and declared his mission a success despite consecutive defeats on his return from a foot injury.

Indeed, Nadal had only competed in two matches since losing to Novak Djokovic in the French Open semi-finals in June before testing his long-term foot problem against Andy Murray and most recently Denis Shapovalov.

However, the 35-year-old's plans to feature in the Melbourne ATP 250 ahead of the Australian Open in early January have suffered a setback after he tested positive for COVID-19 upon landing in his home country on Monday.

Nadal revealed the news on Twitter as he posted: "I wanted to announce that on my return home after playing the Abu Dhabi tournament, I have tested positive for COVID in the PCR test that was performed on me when I arrived in Spain.

"Both in Kuwait and Abu Dhabi we passed controls every two days and all were negative, the last being on Friday and having the results on Saturday.

"I am having some unpleasant moments but I hope that I will improve little by little. I am now homebound and have reported the result to those who have been in contact with me.

"As a consequence of the situation, I have to have total flexibility with my calendar and I will analyse my options. I will keep you informed of any decisions about my future tournaments!"

Nadal was eyeing the Australian Open, which starts on January 17, as his first major comeback, though he earlier admitted his entry was not guaranteed as he evaluated his foot injury and physical fitness.

"I cannot guarantee Australia one hundred per cent, because I need to go home and see how the body responds after these days," Nadal told reporters on Saturday. 

"I have time to make a decision. At this point in my career, I need to go day by day, study each movement well.

"I have been able to show a competitive level against good players even without being in perfect condition. There are things to improve but looking at things with perspective it has been a positive tournament [in Abu Dhabi].

"The main objective is to be healthy enough to do the things that I need to do and aspire to the objectives that I have always had. The illusion and passion continue to exist."

The ATP Tour event in Melbourne, which would be Nadal's first such tournament since August, is due to start on January 3.

Rafael Nadal declared his Abu Dhabi mission a success despite suffering a second consecutive defeat at the Mubadala Tennis Championship on Saturday.

After a hard-fought battle with Andy Murray on Friday served up a reminder of many a classic match between the pair, it was Denis Shapovalov who beat Nadal in his second comeback clash.

Since losing to Novak Djokovic in the French Open semi-finals in June, Nadal had played only two matches due to a worrying foot injury.

That has been a long-term problem and the 35-year-old Spaniard chose this week's event to test how it would stand up to match conditions.

Canadian Shapovalov beat his fellow left-hander 6-7 (4-7) 6-3 10-6, but Nadal has done enough in his two matches, and in a practice session with Andrey Rublev, to be persuaded his prospects for 2022 are looking up, with the Australian Open just a month away.

The 20-time grand slam champion said: "Maybe it was too tough to start after a long time."

But he was laughing as he said that, and added: "The goal is achieved: to be back on court. I've played two matches and played more or less four hours on court.

"I enjoyed it. Congrats to Denis today. I wish you all the very best for the next season, and I'm going to try to keep going with my road."

Nadal said he would return to the tournament in future years, as long as he remains fit and still on tour.

"If I'm still playing tennis, I am always super happy to be here playing," he said. "Hopefully I can keep coming during the next couple of years."

Shapovalov, 22, is one of the ATP Tour's most talented youngsters, striving to make a telling impact while the likes of Nadal, Novak Djokovic and Murray reach the twilight years of their careers.

He said of Saturday's win over Nadal: "Any time I get to go on court against a guy like Rafa is an honour for me.

"It's great to just see you back on the court and see you healthy. Hopefully you can grab a great season and keep going."

Rafael Nadal said it felt "special" to be back on court as the 20-time grand slam champion began his latest comeback with defeat to old foe Andy Murray in Abu Dhabi.

The Spaniard was beaten 6-3 7-5 by Murray at the Mubadala World Tennis Championship, an exhibition event that for the 35-year-old marks an important step towards a full ATP tour return.

Nadal is coming off a year disrupted by the foot injury that caused him to miss Wimbledon, the Olympics and the US Open, playing just one event after June.

With the Australian Open a month away, there is plenty of work for these two still to do, but this was a feast for the eyes as the multiple grand slam champions jostled hard for supremacy.

Murray is down at 134th in the ATP rankings and continues to battle his own body after hip and groin problems. However, eye-catching wins late in the season against the likes of Carlos Alcaraz, Hubert Hurkacz, Jannik Sinner and Frances Tiafoe have suggested there might be good times ahead for him in the new year.

Here the Scot broke Nadal's serve to 15 in the sixth game of the first set to seize the initiative. Nadal appeared to be finding a familiar rhythm in the second set, hitting some tremendous clean winners, and at 0-30 down at 4-4 he serve-volleyed twice in succession to get out of trouble.

A contentious line call gave Murray two break points at 5-5, and although Nadal saved one, he fired long at the end of a super rally on the next point. Murray closed out the contest on his second match point, with Nadal flinging a full-throttle backhand long, 

"It's been special to be back in competition," Nadal said in an on-court interview. "At the same time, it's been a while since we played against each other. I'm super happy to see Andy playing at this great level after all the things he went through.

"For me, as a comeback it was not a bad match for me. It's been a long time since I was out on court in a professional match so I've got positive feelings."

These wily old rivals had met 24 times previously at competitive tour level, all of those encounters coming between 2007 and 2016 with Nadal leading 17-7 in the head-to-head.

Nadal won the ATP's comeback player of the year award way back in 2013, and he finds himself looking to prove himself again in 2022, locked together on 20 slams with Novak Djokovic and Roger Federer.

Murray, who has won three slams but also been a runner-up eight times in the majors, said: "It's great to be back on the court, able to play at a high level again after a very long time. Me and Rafa have played so many tough matches, but we've not played for five or six years.

"That shows both of us have gone through lots of injury troubles and issues, and it's great to just have the opportunity to be on the court with him again.

"Certainly when I was younger I wasn't appreciating it as much as I do now. It's great to be back on the court, I'm so happy that Rafa's back, and I look forward to the next few years."

Murray will play Andrey Rublev for the title on Saturday, while Nadal features again too, taking on Denis Shapovalov in a third-place match.

Spanish tennis great Manolo Santana, a four-time grand slam winner, has died at the age of 83.

Santana won the US Open, Wimbledon and the French Open twice during the 1960s, during which time he spent a period as world number one.

He also won the men's singles tennis tournament at the 1968 Olympics, though it was not recognised as a medal event at the time, while also winning the French Open men's doubles in 1963 and the Davis Cup with Spain on three occasions.

Santana retired in 1977 and in more recent times was regularly seen watching countryman Nadal – the only Spaniard to have won more grand slam titles – from the stands.

Nadal led the tributes to Santana on Saturday with an emotional post on social media.

"I have just received the terrible news of the death of our great Manolo Santana," he wrote on his official Instagram account.

"As I have said many times in the past: thank you very much for what you did for our country and for leading the way for so many. 

"You have always been a reference, a friend and a person close to everyone.

"We will miss you Manolo; you will always be unique and special. Greetings to your family and a lot of strength at this time. We will never forget you."

Rafael Nadal is set to start his 2022 season at the Melbourne ATP 250 ahead of the Australian Open.

Nadal this week appeared on the entry list for the first grand slam of the year, which begins on January 17.

The Spaniard has not featured on the ATP Tour since August, when he lost against Lloyd Harris at the Citi Open in Washington D.C.

But Nadal is going to be back into the swing of things in the next month. The Melbourne 250 starts on January 4 and will serve as a warm-up for the Australian Open.

Gael Monfils is headlining the ATP 250 event in Adelaide during the same week, while Novak Djokovic – whose participation at the Australian Open is as of yet unclear, although he is also listed for entry – is set to lead Serbia at the ATP Cup in Sydney. 

Djokovic has not yet revealed his COVID-19 vaccination status. If he is not fully vaccinated, the 34-year-old may not be able to compete in Melbourne, barring a medical exemption.

Nadal has dropped down to world number six after another injury-hit season, in which he won two titles, triumphing in Barcelona and Rome.

He has only won the Australian Open once, in 2009, but has since been beaten four times in the final, in 2012, 2014, 2017 and 2019.

Since the start of the 2020 season, Nadal has played in four finals, winning them all, including last year's delayed French Open.

Novak Djokovic has been included in the official entry list for the 2022 Australian Open, with Tennis Australia adamant that no loopholes are being explored.

The world number one, who has won nine of his 20 grand slam titles in Melbourne, has not yet disclosed his COVID-19 vaccination status, meaning there is doubt over whether he will be able to participate.

Every person competing or attending the grand slam next month will need to have been fully vaccinated against coronavirus.

However, despite the uncertainty, the 34-year-old was named in the official list of players for the tournament draw.

Djokovic had already been named in Serbia's team for the ATP Cup, which is to be held in Sydney, leading to speculation that he could enter Australia by travelling directly to New South Wales, which has different COVID-19 restrictions to the state of Victoria, and may then seek a medical exemption to get around the rules applying to unvaccinated travellers.

James Merlino, Victoria's deputy premier, responded to these reports, which also suggested Djokovic had the backing of Tennis Australia.

"My view on this is really clear and really simple," Merlino said on Wednesday. "Everyone's looking forward to the Australian Open and everyone who will attend – spectators, players, officials, staff – everyone is expected to be fully vaccinated.

"They're the rules. Medical exemptions are just that – it's not a loophole for privileged tennis players. It is a medical exemption in exceptional circumstances if you have an acute medical condition."

Tennis Australia responded to Merlino's comments with a statement of their own.

"Any suggestion that Tennis Australia is seeking 'loopholes' within this process is simply untrue. Adjudicating on medical exemptions is the domain of independent medical experts. We are not in a position to influence this process and nor would we," the statement read.

"Any application for a medical exemption must follow strict government guidelines based on ATAGI (Australian Technical Advisory Group on Immunisation) clinical advice. This is the same process that applies to any person wanting to enter Australia."

While Djokovic's participation is unclear, Serena Williams is a big-name absentee. The 40-year-old, who is one shy of matching Margaret Court's record tally of 23 grand slams, had been expected to play in Melbourne.

Roger Federer had already confirmed his absence, but Rafael Nadal is set to compete for the first time since August.

World number two and US Open champion Daniil Medvedev takes his place in the draw, as does 2020 Australian Open finalist Dominic Thiem.

Australian world number one Ash Barty headlines the women's field, with Naomi Osaka, US Open winner Emma Raducanu and WTA Finals champion Garbine Muguruza also in the draw.

Bianca Andreescu, the 2019 US Open champion, has decided to skip the event to focus on her mental wellbeing.

Rafael Nadal conceded that Novak Djokovic will likely end his career with the most grand slam singles titles in men's tennis history, ahead of the Spaniard and Roger Federer.

The so-called 'Big Three' of tennis have long dominated the ATP Tour, with all three sitting on 20 major titles after Djokovic collected three from a possible four in 2021.

Djokovic, who secured a year-end number one ranking for a record seventh time, would have completed a clean sweep if it were not for Daniil Medvedev in the US Open final.  

Nadal, by contrast, missed large parts of the season with a foot injury, while Federer was similarly ruled out for a substantial period after requiring a third knee operation in the space of 18 months.

Nadal could make a return for the Australian Open in January, an event that the world number one may miss due to a vaccine mandate, but he still expects Djokovic to hold the record for major titles when the trio has retired.

"Djokovic is best positioned to be the [men's] player with the most grand slams," Nadal said to Movistar.

"You don't have to fool yourself – Federer is where he is and I am where I am. However, Djokovic is playing well and in a good moment.

"That is the reality, and you can't ignore it. We don't know what is going to happen in nine months' time, but he is the favourite right now."

Nadal triumphed at Roland Garros in 2020 but has only appeared at two majors since, while Federer – who hopes to return to tour-level action in 2022 – last collected a grand slam title at the Australian Open in 2018.

Nadal is glad that the likes of Stefanos Tsitsipas, Alexander Zverev and Medvedev, who only dropped one set across the entire tournament as he denied Djokovic the perfect year, are taking over.

"They are no longer the Next Gen, we do not have to make it eternal," Nadal said of the new 'Big Three' in tennis.

"Players like Medvedev, Zverev or Tsitsipas have already passed that stage of the Next Gen, they are the current generation, the present."

Rafael Nadal intends to make his Tour comeback next month and plans to play at the 2022 Australian Open.

The 20-time major champion has not played since a defeat to Lloyd Harris at the Citi Open in August.

The 35-year-old, who withdrew from Wimbledon and the Tokyo Olympics after losing to Novak Djokovic in the French Open semi-finals, also pulled out of the US Open due to a recurring foot injury.

Nadal has spent time training in Mallorca this month following treatment in Barcelona and said he was not sure when he would make his return to action.

Speaking at a sponsor event in Paris, Nadal said he hopes to play at the World Tennis Championship next month before a possible tilt at the first grand slam of next year, an event he has won just once back in 2009.

"My plan is to play Abu Dhabi in December and then in a tournament before Australia and then the Australian Open. That's my goal," Nadal said. "We're working hard to make it happen.

"The injury in my foot still needs to get a little better, but I'm already training almost an hour and a half a day so that's positive. Some days are better than others, but I'm starting to have a lot more positive days than negative ones.

"So, I'm on the right track. I'm training, I'm feeling better. I'm back on the court."

World number eight Casper Ruud and world number 13 Denis Shapovalov are two of the big names from the ATP Tour to have confirmed they will play in Abu Dhabi in the event that runs from December 16-18.

Women's Olympic gold medallist Belinda Bencic and surprise US Open champion Emma Raducanu have also signed up to make their tournament debuts.

The Australian Open, won this year by Novak Djokovic, is due to start on January 17.

Daniil Medvedev says it is "logical" that the age of Rafael Nadal, Roger Federer and Novak Djokovic has made it easier to play against the 'Big Three' of men's tennis.

For so long, that triumvirate has dominated the ATP Tour, with Djokovic winning three of the four grand slams on offer in 2021 – denied only a clean sweep by Medvedev at the US Open.

Nadal has struggled with a foot injury for most of the year, though, a problem that saw him miss out on Wimbledon, the Tokyo Olympics and Flushing Meadows after losing to Djokovic in the French Open semi-finals.

Federer, similarly, has missed large parts of the 2021 term after requiring a third operation on his right knee in the space of 18 months.

Medvedev accepted Djokovic had proven "he can beat everyone" in another sensational season, but – while heaping praise on a golden generation of tennis – the Russian said it is natural that time has caught up with all three.

"It would be silly to deny it…[it's] logical," he told reporters about the prospect of younger players replacing the greats at the top of the men's game.

"It is something natural. It is not something that I decide. It is evidence. They get old and now it is easier to play against them."

Medvedev only dropped one set across the entire tournament en route to securing a maiden slam at the US Open.

However, Medvedev was reticent to say the shift in power has taken place.

"I do not dare to speak of a generational change in tennis," Medvedev said.

"It is the best generation in the history of tennis.

"Nobody can come close to the results they have achieved.

"We all want to defeat that troika. And they don't want to lose either."

Medvedev then focused on his own progress, having pulled out of the Kremlin Cup citing injury problems from an early exit in Indian Wells.

"I want to win more Grand Slams," he continued. "I also want to be number one and be at the top of tennis for many years. But you can't win every tournament, it's impossible."

Twenty-time grand slam winner Rafael Nadal has refused to put a timeline on his comeback to competitive tennis and will only return when he is in "good condition".

Nadal has not played since early August when he lost to Lloyd Harris in the third round at the Citi Open, before withdrawing from the US Open due to a recurring foot injury.

The 35-year-old Spaniard had in June pulled out of Wimbledon and the Tokyo Olympics shortly after losing to Novak Djokovic in the French Open semi-finals, saying he was "listening to my body".

Nadal, who will not return this season, has been seen training in Mallorca after last month receiving treatment in Barcelona, offering hope of a return.

"I want to recover from this injury in good condition," Nadal told a news conference.

"I don't know when I will play again, I work a lot every day, I follow a specific plan with a marked roadmap and with very clear objectives."

The next major on the calendar is the 2022 Australian Open to be played in Melbourne in January although Nadal would not commit to participating.

"I will not say what those objectives are, because there are always things that I can't control 100 per cent, but inside my head I'm clear on what my objectives are and I trust that things will follow a positive course," he said.

"Not everything depends on me, but I am confident that my daily efforts will pay off and allow me to return soon."
