Chelsea have hired the All Blacks mind coach who introduced a "no d***heads" policy as Graham Potter looks to turn the Blues into winners.

Heavy investment in players since Todd Boehly came in as owner has not yet been followed by success on the pitch, with Chelsea a disappointing ninth in the Premier League.

Thomas Tuchel was sacked in September and his replacement, Potter, is battling to prove he can be the coach to deliver strong results and trophies to Stamford Bridge.

Now Gilbert Enoka is heading to the London club after making an impressive impact in rugby union with New Zealand over the past 20 years.

Enoka, who stepped up from being mental skills coach to become leadership manager with New Zealand, will join up with Chelsea on what New Zealand said was a "short-term consultancy basis".

The incoming expertise should be a boost to Potter, with the widely acclaimed Enoka having been part of an All Blacks set-up that won Rugby World Cup titles in 2011 and 2015.

Chelsea have spent around £600million on new players in the past two transfer windows, without their sprees having had any obviously positive effect on results, and installing a positive mindset appears to be what they are looking at achieving.

Enoka revealed in early 2017 how his famous policy functioned within the New Zealand ranks, saying: "A d***head makes everything about them.

"We look for early warning signs and wean the big egos out pretty quickly. Our motto is, 'If you can't change the people, change the people'."

Nick Kyrgios has avoided a criminal conviction after pleading guilty to a charge of assaulting an ex-girlfriend.

Kyrgios, the ATP world number 20, was sentenced at a magistrates' court in Canberra on Friday.

The 27-year-old admitted to pushing his ex, Chiara Passari, to the ground during an altercation in January 2021.

However, magistrate Beth Campbell spared Kyrgios a criminal conviction, noting he had been: "A young man trying to extricate himself from a heightened emotional situation".

Ms Campbell said Kyrgios "acted in the heat of the moment" and chose to deal with him "in the same way I would deal with any young man in this court", adding he is a "young man who happens to hit a tennis ball particularly well".

In a post on his Instagram story after the ruling, Kyrgios said: "I respect today's ruling and I'm grateful to the court for dismissing the charges without conviction. I was not in a good place when this happened and I reacted to a difficult situation in a way I deeply regret.

"I know it wasn't OK and I'm sincerely sorry for the hurt I caused.

"Mental health is tough. Life can seem overwhelming. But I've found that getting help and working on myself has allowed me to feel better and to be better.

"I can never thank Costeen [Hatzi, his girlfriend], my family and friends enough for supporting me through this process. I now plan to focus on recovering from injury and moving forward in the best way possible."

The court heard Kyrgios pushed Ms Passari to the ground after she had prevented him from driving away during an argument on January 10, 2021.

Kyrgios' lawyer Michael Kukulies-Smith explained last year's Wimbledon finalist had been attempting to de-escalate the situation by calling a taxi and had sworn at Ms Passari and told her to leave, before moving her away from the car.

It was agreed that Kyrgios said "I'm serious, I'm going to..." as he then pushed Ms Passari in the shoulder. Ms Passari said she felt some pain and also grazed her knee.

Kyrgios subsequently apologised.

Mr Kukulies-Smith told the court that there was "a relationship between the mental health and the offending", though noted Kyrgios no longer suffers to the same extent.

Psychologist Sam Borenstein told the court that Kyrgios, who missed this year's Australian Open due to injury, had "recurrent" mental health issues, including depression, suicidal ideation and insomnia, that were nevertheless improving.

Manchester United "will conduct its own process" before determining next steps after all charges against Mason Greenwood were dropped.

The 21-year-old forward was arrested in January 2022 and was due to stand trial in November on accusations of attempted rape, assault and coercive control.

However, the Crown Prosecution Service (CPS) confirmed on Thursday that all charges have been discontinued.

Greenwood last featured for United on January 22 last year in a 1-0 victory against West Ham and has been suspended by the club ever since.

United now plan to conduct their own review before any further decisions are made regarding his association with the club.

A statement read: "Manchester United notes the decision of the Crown Prosecution Service that all charges against Mason Greenwood have been dropped.

"The club will now conduct its own process before determining next steps. We will not make any further comment until that process is complete."

Boston Celtics' Robert Williams says team-mates Jayson Tatum and Jaylen Brown are using last year's close call as motivation to win the NBA Championship this time around.

Tatum and Brown were scintillating as the Celtics cruised to an emphatic 139-96 victory over the Brooklyn Nets on Wednesday.

The duo became the first team-mates in franchise history to each make seven three-pointers in the same game, doing so in just three quarters, while Tatum's plus-42 heading into halftime saw him better Kevin Garnett's Celtics record for a single-half plus/minus.

Tatum finished with a game-leading 31 points as well as nine rebounds and four assists, while Brown had 26 points, three assists and three rebounds. It was the eighth time this campaign that the pair have each accumulated 25 points or more.

Williams added a useful 16 points and nine rebounds from just 19 minutes of action, and he said Tatum and Brown are "carrying the team" as they look to make amends for last year's NBA Finals defeat to the Golden State Warriors.

"They take all criticism. They take all the 'he said, she said'," Williams said.

"But I love how they've been responding. Feel like they're hungry, really. You know what I'm saying? Still p***** about last year."

Only Luka Doncic of the Dallas Mavericks (1,538) has more points on the board than Tatum's 1,493 this season, while the latter's 31.1 points per game average is a career-best.

Tatum, for his part, feels the sustained level of performance from Brown and himself has been overdue as he noted "it's not done" until the Celtics clinch their first championship since 2008.

He told reporters: "It's been a long time coming. We've had our good times and not-so-good times, but I think those are just growing pains.

"We were just 19-year-old kids that came into the league hungry and trying to help our team win. We've had to learn how to play in this league, learn how to play with each other, learn how to lead the team.

"I feel like we're still a long way ultimately from where exactly we want to be, but we've made amazing strides from the beginning.

"You can tell we were ready to go from the jump. We've still got a long way to go. It's not done until we win a championship."

It was the first time in franchise history that Boston, who top the Eastern Conference with a league-best 37-15 record, outscored their opponent by at least 30 points in the first quarter, in which they scored 46 points before going on to record their biggest victory of the season.

Nets star Kyrie Irving, whose 20 points was a team-high for Brooklyn, felt there was little his side could do as they slumped to their heaviest loss since a 44-point defeat to the Portland Trail Blazers in February 2014.

"It's clear as day that they want to win the championship, and they're not wasting any time in the regular season," Irving said. "Tonight I felt like we were just one of those teams in the way, and you know, we just can't be one of those teams in the way.

"We've got to be one of those teams that stands up to them and at least shows them that we're going to be competition for them moving forward, which I believe we are. But we just didn't show it."

Philadelphia Eagles reserve offensive linesman Josh Sills has been indicted on rape and kidnapping charges from an alleged 2019 incident in Ohio, authorities said on Wednesday.

Sills engaged in alleged sexual activity that was not consensual and held a victim against her will in December 2019, Ohio attorney general Dave Yost of Guernsey County said in a news release.

The case, which was immediately reported and investigated, was presented to the grand jury on Tuesday and is being prosecuted by the attorney general's office.

Sills, an undrafted free agent who has played just once this season, was ordered to appear in court in Ohio on February 16, four days after the Eagles' Super Bowl LVII clash against the Kansas City Chiefs.

"Sills may not participate in practices and games or travel with the team while on the Commissioner Exempt List," the NFL said in a statement.

"The matter will be reviewed under the NFL's personal conduct policy."

The Eagles added in a statement: "The organisation is aware of the legal matter involving Josh Sills. 

"We have been in communication with the league office and are in the process of gathering more information. We have no further comment at this time."

Sills, who played for West Virginia and Oklahoma State, was signed by the Eagles as an undrafted free agent in April.

The International Olympic Committee (IOC) has reiterated it will stand by sanctions imposed against Russia and Belarus after appearing to open the door for their inclusion at Paris 2024.

The two nations are currently banned from Olympic competition following Russia's invasion of Ukraine last year.

But IOC statements last month appeared to clear a pathway for the inclusion of athletes from both countries to compete under a neutral flag.

Now, however, the governing body has sought to reaffirm its stance, in particular as a response to comments made by Stanislav Pozdnyakov, head of Russia's Olympic Committee

"The sanctions against the Russian and Belarusian States and Governments are not negotiable," it said in a statement.

"They have been unanimously confirmed by the recent Olympic Summit meeting on 9 December 2022."

Sanctions reiterated by the IOC include no international sports events being organised or supported in either country by a National Olympic Committee.

In addition, no sports meeting or event is allowed to fly Russian and Belarusian flags or colours, while government and state officials are barred from attendance.

The decision to potentially let athletes from both countries compete next year has enraged Ukraine, who could boycott the event in protest.

President Volodymyr Zelensky doubled down on criticism of the IOC, stating that the inclusion of Russian or Belarusian athletes would tell "the whole world that terror is somehow acceptable".

Russian athletes competed under the flag of the Russian Olympic Committee rather than their country at Tokyo 2020 amid a suspension from the World Anti-Doping Agency.

The Los Angeles Lakers are furious after an obvious foul on LeBron James' potential game-winner was missed, with the Boston Celtics going on to secure a 125-121 victory in overtime.

Playing in Boston, James was spectacular with a game-high 41 points on 15-of-30 shooting, adding nine rebounds and eight assists, but the game was tied at 105-105 after Jaylen Brown's and-one with four seconds remaining.

The four-time MVP and four-time NBA Finals MVP would be the player entrusted with the last shot for the Lakers, and after driving left and getting all the way to the rim, James was smacked on his shooting arm by Jayson Tatum with under one second on the clock.

But the foul went un-whistled, with James, All-NBA team-mate Anthony Davis and the entire Lakers bench erupting in fury as the game was sent to overtime.

Los Angeles guard Patrick Beverley was issued a technical foul after bringing over a camera to the referee in an effort to show crew chief Eric Lewis the clearly botched call, and the Celtics went on to score 20 in the extra period, led by Brown with 11 of his 37 total points.

Speaking after the loss, Davis made it clear he felt cheated by the referees.

"It was bull**** at the end of the day," he said. "It’s unacceptable, and I guarantee nothing will happen to the ref. We got cheated tonight, honestly. 

"[Beverley] got all ball on Brown, [but they] called a foul. LeBron, they smack across his arm. Unacceptable, to be honest. The refs were bad – they were bad tonight."

James echoed those sentiments, saying this is not the first time this season he has felt disrespected by officials.

"You saw my reaction… it’s challenging," he said. "I don’t get it. 

"I'm attacking the paint just as much as any other guy in this league that’s shooting double-digit free throws a night. I don’t get it. I don’t understand it."

He added: "You guys seen some of the games we lost this year, with late-game missed calls. I don’t understand what we're doing. 

"I watch basketball every single day. I watch these games every single game, and I don’t see it happen to nobody else. It's just weird."

Head coach Darvin Ham joined the chorus of discontent.

"The best player on Earth can’t get a call – it’s amazing," he said. "You have to call a cat a cat, you can’t look at something and try to pretend it’s not what it is. 

"He’s a guy that tries hard to play the right way. Doesn’t flop, plays downhill, plays a strong, physical brand of basketball. 

"Just because he doesn’t flop or doesn’t flail and he’s not screaming when he’s shooting the ball like I see a ton of other players doing, he gets penalised for it.

"As much as you try not to put it on officiating, it’s becoming increasingly difficult. I don't want to see another Last 2 Minute report – they can save that. It doesn't do no one any good."

In an Instagram story, where he included a still photo of the foul, Lakers guard Dennis Schroder also voiced his frustration.

He wrote: "The refs gotta start getting fined for their mistakes! They also giving technical fouls to people who are reacting to their mistakes.

"The replay center should also use replay to get these calls right, especially on an important play like the OBVIOUS foul on LeBron at the end of the game.

"This needs to stop… to lose 3-5 games this season off of referees' mistakes is really hard."

In an uncommon occurrence, crew chief Lewis confirmed the botched call immediately after the game finished.

"There was contact," he said. "At the time, during the game, we did not see a foul. The crew missed the play."

The loss has the Lakers fall to 23-27, sitting 13th out of 15 teams in the Western Conference.

Joel Embiid made it clear he is only concerned about winning a championship after dominating in the Philadelphia 76ers' 126-119 victory against reigning back-to-back MVP Nikola Jokic and the Denver Nuggets.

Embiid – who has finished runner-up in each of the past two MVP votes – was spectacular on Saturday, finishing with a game-high 47 points on 18-of-31 shooting, a game-high 18 rebounds and equal game-highs with three steals and two blocks.

He outplayed Jokic, who still posted a terrific stat line of 24 points (eight-of-12 shooting), nine assists and eight rebounds, but his seven turnovers were the third-most he has had in a game this season,

It continued a remarkable campaign for Embiid, improving his league-leading scoring average to a career-high 33.8 per game, while also shooting a career-best 53.2 per cent from the field. He is shooting a career-best 86.1 per cent from the free throw line while leading the league at 10.0 made free throws per game.

When asked after the win if he feels he should be the MVP, Embiid said he is no longer concerned about the award.

"I don't know, that's up to you guys to decide," he said. "Like I told you, I'm done arguing for myself. It's all out there.

"But the focus is on winning. As long as we win, I know everything is going to take care of itself. If we keep winning, and everyone stays healthy, I've got a better chance of going out there and winning a championship."

Embiid also had his streak of five consecutive selections as an All-Star starter snapped this past week as Giannis Antetokounmpo, Kevin Durant and Jayson Tatum claimed the three frontcourt spots in the East.

He said he feels that is an indication that he is "not well-liked", but he is not bothered by it.

"I'm used to it," he said. "It's not the first time. I think it's more of a motivation to go out and win the whole thing – that's the only way I'm probably going to get that respect.

"I was not surprised, I think it's well documented that I'm not well-liked. That's cool. I don't know if it's because I troll a lot or that I guess I'm an a****** – but it's cool. 

"I keep being me, I keep being an a******, and I keep trolling, and if people don't like it, that's their problem. But like I said, it all goes back to winning."

The 28-year-old believes winning would cure everything, and that the current 76ers roster – with a healthy James Harden – has the balance required to go all the way.

"You've got James Harden, obviously he's been playing great basketball," he said. "You've got Tyrese Maxey, Tobias has been great, P.J. Tucker... we've got a group that fits with each other.

"We'll find that out in the postseason. But I think as far as the fit, you've got everything. Everybody fits with each other, we've got shooters, we've got defenders, and we've got James Harden. So I think we've got a good chance."

The 76ers are now 32-16, sitting second in the Eastern Conference while owning the third-best record in the league.

Memphis Grizzlies coach Taylor Jenkins said his team have been deeply affected following the death of fan Tyre Nichols.

Nichols, 29, died on January 10, three days after he was beaten by five police officers after a traffic stop in Memphis, Tennessee.

The five officers have been sacked and charged with second-degree murder, assault, kidnapping, official misconduct and official oppression. 

Police have released bodycam and CCTV footage of the incident, in which Nichols can be heard protesting his innocence and calling for his mother.

The footage was released just prior to the Grizzlies' meeting with the Minnesota Timberwolves on Friday.

Before the game, Jenkins told Bally Sports: "It's been tough being on the road, not being home.

"I wish I could extend my arms through this camera right now to the family. They're going through a lot.

"The senseless loss of life for Tyre Nichols has really hit us hard."

Nichols' mother, RowVaughn Wells, said in an interview that she felt "sorry" for the officers who killed her son.

"People don’t know what those five police officers did to our family. And they really don’t know what they did to their own families. They have put their own families in harm's way," she said.

"They have brought shame to their own families. They brought shame to the Black community. I just feel sorry for them. I really do. Because they didn't have to do this.

"They had beat him to a pulp. He had bruises all over. His head was swollen like a watermelon. His neck was busting because of the swelling. They broke his neck. His nose was like an S.

"They actually just beat the crap out of him, so when I saw him, I knew my son was gone. Even if he did live he would have been a vegetable."

Wells said he cried after seeing the interview, though disclosed after Friday's 111-100 defeat that he had not watched the disturbing footage of the arrest and subsequent beating.

"There's way harder things on in the city versus what's going on with our basketball right now," Jenkins told reporters.

"I'm proud of our guys going out there. We're playing with heavy hearts, but we're also playing for our city that's going through a lot right now.

"My words will only mean so much. I want to continue to encourage people to put their arms around each other.

"To put their arms around the Nichols family, the Wells family to remember a beautiful life in Tyre Nichols – who I did not know, but I'm learning about.

"Our guys are still grappling with everything going on. We have been just getting all the updates over the last couple of days on this road trip.

"No one's been able to see the video but we do know of a tragedy that's taking place and just trying to grapple with that so there's still ongoing dialogues; everything's on the table to how we want to support our city, support the Nichols family."

Nichols' death has echoes of the murder of George Floyd, who died in police custody in Minneapolis in 2020, sparking civil rights protests and riots in the United States and many other nations.

The Grizzlies were among several NBA teams to release statements, with Memphis saying they were "distraught to find ourselves dealing with a needless loss of life due to police brutality". 

An NBA statement read: "The images of Tyre Nichols' life needlessly cut short are horrifying.

"While there have been steps toward accountability in this instance, the NBA family remains committed to partnering with advocates, policymakers and law enforcement to work toward solutions to the issues we continue to face."

Memphis police chief Cerelyn Davis said there was a "disregard of basic human rights" and called the officers' actions "heinous, reckless and inhumane".

Joel Embiid found the experience of facing Ben Simmons for the first time no different to any other night as the Philadelphia 76ers beat the Brooklyn Nets in a thriller.

Embiid came up against his former team-mate Simmons for the first time at Wells Fargo Center on Thursday and the 76ers came out on top, winning 137-133.

Simmons was traded to the Nets almost a year ago in a deal that saw James Harden make the move to Philadelphia.

Three-time All-Star point guard Simmons scored 12 points, claimed five rebounds and provided five assists as the Nets slipped to 29-18.

Embiid finished with 26 points and 10 rebounds for a 76ers side that have won six games in a row and sit second in the Eastern Conference at 31-16 behind the Boston Celtics (35-14).

Asked how it felt doing battle with Simmons for the first time, he replied: "Nothing. Just like every single night, [I am trying to] just freaking kill whoever is in front of me.

"My mentality is always about scoring. If I get doubled, make the right pass, but if I get played one-on-one, or I see an opportunity to go score, I'm going to go score."

Doc Rivers, the 76ers head coach, said: "The first play, Ben is guarding Joel and it was like it was a party.

"It was hilarious. That's when I turned to our coaches and said, 'This is a boxing crowd tonight. They want to see them drop the basketball, turn and duke it out. And [Simmons and Embiid] went at each other, which is fun and good."

Despite another win, Rivers felt his players could have handled the occasion better.

He added: "I thought the team overall did. We got caught up in all the c*** going on tonight.

"There was a lot of chippiness, and that's good, but play above it, stay above it. Keep playing. I didn't think we did that."

Victoria Azarenka sympathised with Novak Djokovic as she stated tennis players are "not villains" after reaching the Australian Open semi-finals for the first time in a decade.

Azarenka beat Jessica Pegula 6-4 6-1 on Rod Laver Arena on Tuesday to set up a last-four meeting with Elena Rybakina.

Former world number one Azarenka came in for criticism when she took a medical timeout during her last semi-final at Melbourne Park back in 2013, delaying her match against Sloane Stephens by 10 minutes.

The Belarusian, who is now 33, returned to beat Stephens and went on to defend successfully her title.

Questions have been raised over the extent of a hamstring issue nine-time Australian Open champion Djokovic has been contending with as he attempts to match Rafael Nadal's tally of 22 major triumphs this weekend.

Azarenka feels it is out of order for such suspicions to be raised by people who are not aware of the facts.

She said: "Do you know what happened 10 years ago? That's the thing.

"It was one of the worst things that I've ever gone through in my professional career, the way I was treated after that moment, the way I had to explain myself until 10:30pm at night because people didn't want to believe me. I actually can resonate what Novak said the other day.

"There is sometimes incredible desire for a villain and a hero story that has to be written. But we're not villains, we're not heroes, we are regular human beings that go through so many, many things.

"Assumptions and judgements, all those comments, are just s*** because nobody's there to see the full story. It didn't matter how many times I said my story, it did not cut through.

"Actually it's funny that you're saying that because I was thinking about it. It took me 10 f****** years to get over it. I finally am over that."

Asked to expound what the judgements or assumptions she experienced were, Azarenka said: "I've been called that I'm cheating, that I'm faking, that I was trying to throw people off their game. It's everything that is so wrong about my character if somebody actually knows me.

"At some point I've heard that she has this thing that is bad or this thing is bad, whatever. At some point you're like, 'Really? Am I?'. Those doubts starts to creep in.

"Now I just don't care. I am more and more confident in what I know about myself, and I'm at peace with that. Those comments, judgements, they're there. I notice them. But I don't care."

Barcelona head coach Xavi apologised on Sunday after facing a wave of criticism for his comments after the arrest of Dani Alves on sexual assault allegations.

Xavi, a former team-mate and coach of Alves, said in a press conference on Saturday he was "in a state of shock" after hearing the news.

Brazilian right-back Alves was arrested in Barcelona on Friday after it was alleged he assaulted a woman in a nightclub bathroom.

The 39-year-old, who has been refused bail, denied committing the offence when he spoke to Spanish broadcaster Antena 3 in early January.

Xavi also said on Saturday that "justice will dictate" the situation, but he faced flak, particularly on social media, for focusing on Alves, rather than expressing concern for the alleged victim.

He looked to clear that up following Barcelona's 1-0 win against Getafe on Sunday, saying: "What I said was misinterpreted, or I was not as forceful as I should have been, but it is important that I explain myself.

"It is a difficult and delicate subject. Yesterday I ignored the victim, but I want to make it clear that any act of gender-based violence or rape must be condemned, whether Dani or anyone else does it.

"I feel bad that Dani could have done it, but on this issue you have to be very strong. Yesterday I was not very lucky with my words and I apologise. I know that my voice is very important, because I represent a club like Barca. I am truly sorry, it has not been a pleasant day for me."

Borussia Dortmund striker Sebastien Haller called his debut an "unforgettable" experience after his first appearance since recovering from testicular cancer.

The Ivory Coast international signed for the Bundesliga outfit last year, but was diagnosed with a tumour just days after making the move from Ajax.

Having gone through several rounds of treatment, Haller scored a hat-trick in a friendly with Basel earlier this month, and enjoyed his maiden competitive outing in Sunday's 4-3 win over Augsburg.

After receiving a standing ovation following his arrival as a second-half substitute, the forward was overwhelmed by the response

"The welcome I received was something unbelievable, unforgettable," he told broadcaster DAZN. "I was just happy to be here and to take my first steps on the pitch.

"It's something we can take with the team, this atmosphere, we can use [it] to win games."

Haller, who sported boots with the slogan 'F*** Cancer*, showed no signs of serious rust during his half-hour cameo for the Black and Yellow, though he acknowledged he still has work to do.

"There are still a few things to do to reach my full fitness," he added. "For the moment I'm just focused on the work. You will see in the next weeks and months how it's going."

Dortmund lie sixth in the Bundesliga, seven points off leaders Bayern Munich in what is shaping up to be a competitive race for European qualification. 

They next travel to Mainz on Wednesday before wrapping up the month on the road against Bayer Leverkusen next Sunday.

Jamahal Hill claimed the UFC light heavyweight title with a five-round pummelling of Glover Teixeira by unanimous decision at UFC 283 in Rio de Janeiro on Saturday.

The 31-year-old American won the vacant title in dominant fashion, leaving his opponent bloodied and earning a lopsided vote 50-44, 50-44, 50-44.

Hill's punching combinations and head kicks were too much for Brazil-born former titleholder Teixeira, with the American claiming victory immediately upon the conclusion of the fifth round, having had 248-108 total strikes and 232-75 significant strikes.

"Anything is possible," Hill said during his post-fight interview. "Hard work, dedication, accountability. Don't let nobody tell you nothing.

"Too many people told me I couldn't do it, that it was impossible. I needed to do it in one round. I couldn't go five. What the f*** you got to say now?"

Teixeira was badly hurt by a second-round head kick, along with a third-round punching combination, leaving him with cuts above his eyes. Teixeira announced his retirement after the fight.

In the flyweight division, which co-headlined UFC 283, Mexican Brandon Moreno defeated Deiveson Figueiredo by TKO in the third round by doctor stoppage after the Brazilian's right eye closed over.

Figueiredo sustained the injury from a Moreno left hook, but the Mexican was ahead at the time on all three judges' scorecards.

The Moreno win came in their fourth meeting over the past 25 months, with Figueiredo declaring his intention after the fight to move up a division.

Xavi was "in a state of shock" following news of former Barcelona star Dani Alves being arrested on suspicion of carrying out a sexual assault.

Brazilian right-back Alves was arrested in Barcelona on Friday after it was alleged he assaulted a woman in a nightclub bathroom.

The 39-year-old denied committing the offence when he spoke to Spanish broadcaster Antena 3 in early January.

Alves, who has also played for Paris Saint-Germain and Sevilla, gave a statement to the Mossos d'Esquadra police force on Friday before the public prosecutor's office requested that he should be detained and not granted bail.

He has been kept in prison while investigations continue, and his contract with Mexican club Pumas UNAM has been terminated.

Xavi, a former Barcelona team-mate of Alves, signed the defender for a short second Barcelona stint last season.

Speaking in a Barcelona pre-match press conference on Saturday, Xavi said: "It is difficult to comment on a situation like this. I am surprised, shocked, in a state of shock.

"It is a matter of justice. Justice will dictate whatever."

Alves became the oldest player to feature in a World Cup match for Brazil when he played against Cameroon in Qatar last month.
