Bayern Munich are still waiting on Leon Goretzka and Javi Martinez to return negative coronavirus tests so they can resume first-team duties.

The midfield duo are set to be absent once again for Friday's Bundesliga match at Hertha Berlin after testing positive for COVID-19 last week.

Speaking at a pre-match news conference, head coach Hansi Flick confirmed Martinez's spell of self-isolation is set to end on Wednesday, with Goretzka having to wait until Friday.

After the Hertha game, European champions Bayern will fly to Qatar to commence their Club World Cup campaign.

"With Javi and Leon it is the case that we do a test after the quarantine, I can't comment on that because I don't have the results," he said.

"Javi has to take the test and then it will be determined if he still has the virus in his body. We have to wait from day to day.

"We also know with Leon that it takes a few days longer. He also has to be tested, everything will depend on that."

With or without Goretzka and Martinez, Flick conceded the Club World Cup will place an additional strain upon Bayern within an already condensed schedule.

"Qatar is very stressful, we have the flight and the games on Mondays and Thursdays. It was clear to us that we would not have time for proper training," he said.

"The team, coaching team and club want to win the next title, we all know that it is not easy.

"In addition to getting some vitamin D [sunshine], it is also a change from everyday life, even if the journey is dangerous.

"We want the sixth title in a year, the team would make history."

Flick had some words of encouragement for Niklas Sule, the defender who has only started two of Bayern's past six Bundesliga matches and was recently linked with a move to Chelsea.

"Niklas is an absolute option, whether in the centre or full-back position," he said of the Germany international, who suffered a ruptured anterior cruciate ligament last season.

"He did well at Schalke [last month's 4-0 win where Sule played at right-back]. Don't forget that he had a long injury.

"Niklas is a fast player who is serene on the ball and helps shape the game from behind. Given his size, he has absolute strength and I'm glad he's on our team.

"We will see how everything develops and how he sees his future. I am satisfied with his development, you can rely on him."

Preparations for the Australian Open were dealt a fresh blow on Wednesday when a member of hotel staff tested positive for coronavirus, although Victoria's premier insists the tournament is not under threat at this stage.

A 26-year-old worker at the Grand Hyatt Hotel returned a negative test at the end of his previous shift on January 29 but subsequently developed symptoms and tested positive on Wednesday.

As a result, Melbourne and the wider Victoria region has reverted to its New Year's Eve restrictions of gatherings at home being limited to 15 people and masks having to be worn in public indoor spaces.

In terms of the specific impact upon participants in the Australian Open, players, officials and support staff who were staying at the hotel during this period must now isolate and undertake a COVID-19 test.

The number of tournament-related personnel classed as "casual contacts" related to the incident is estimated to be between 500 and 600.

Nevertheless, Victorian premier Daniel Andrews told a news conference he was confident the Australian Open would go ahead as planned, even though the requirement that some players isolate and test could have an impact upon warm-up tournaments that are ongoing at Melbourne Park.

"There's about 500-600 people that are either players and officials and others who are casual contacts," Andrews said.

"They will be isolating until they get a negative test and that work will be done tomorrow so it might have an impact on tomorrow's play in the lead-up event, but at this stage there's no impact to the tournament proper.

"That's important to us, but the issue we're most focused on is much broader. That's about public health and public safety and that's why we've really pounced on this."

The Australian Open is scheduled to run from February 8-21.

Daniil Medvedev and Andrey Rublev produced ruthless performances as Russia cruised into the ATP Cup semi-finals.

Russia followed up their day-one win over Argentina with victory against Japan to ensure they will finish top of Group D.

Rublev got things rolling with an emphatic 6-1 6-3 win over Yoshihito Nishioka and Medvedev dispatched Kei Nishikori in a 6-2 6-4 triumph.

Those results meant the subsequent doubles match – which Japan won – would not be relevant.

"I am really happy for the team," said ATP Finals champion Medvedev, who has now won 12 matches in a row on the tour.

"Reaching the semi-finals is a big step – I am really happy that we made it in both singles. Both matches were straight sets, so really happy for the team and hopefully we can go further than that."

Italy, who had beaten Austria on the opening day, are also through after Fabio Fognini and Matteo Berrettini earned wins in straight sets over France duo Benoit Paire and Gael Monfils on Wednesday.

France play Austria next but neither team can catch Italy in Group C.

Alexander Zverev won a thriller against Denis Shapovalov 6-7 (5-7) 6-3 7-6 (7-4) to ensure Germany defeated Canada.

It was a first win at the ATP Cup for US Open runner up Zverev, who had a miserable tournament in 2020.

That sets up a day three contest for Germany against Novak Djokovic and Serbia where the winning team will progress to face Russia.

KYRGIOS AND WAWRINKA THROUGH

Nick Kyrgios – playing his first tournament for a year – made it two wins from two at the Murray River Open, defeating fellow Australian Harry Bourchier 6-2 7-6 (9-7).

First seed Stan Wawrinka survived a scare before prevailing against Mikhail Kukushkin to win 4-6 6-3 6-1 in just under two hours.

Wawrinka will take on Alex Bolt in the last 16, while Kyrgios should be tested against fourth seed Borna Coric.

At the Great Ocean Road Open, top seed David Goffin crashed out as world number 146 Carlos Alcaraz celebrated a shock 6-3 6-3 victory.

Karen Khachanov and Jannik Sinner were among the seeds who progressed, both winning without dropping a set.

Serena Williams roared into the quarter-finals of the Yarra Valley Classic with a 6-1 6-4 victory over Tsvetana Pironkova on a star-studded day of action in Australia.

The 23-time grand slam champion was in fine form at Melbourne Park, where the biggest names in women's tennis were competing across multiple tournaments, as she sealed a straight-sets triumph to continue her preparations for a shot at an eighth Australian Open title.

In doing so the 39-year-old extended her head-to-head record over the Bulgarian to 6-0 and was delighted to get the job done.

"It's definitely nice to get another win," the American said during her on-court interview.

"She's clearly a great player, so it wasn't easy, but it was good to come through."

Speaking at her media conference, Williams added: "Last time it was an incredible three-set match, so today I was like, 'All right, let's really try and focus and learn to do better than last time.'"

World number one Ash Barty had a less straightforward path to the last eight, requiring three sets to see off Marie Bouzkova.

The home hope ultimately prevailed 6-0 4-6 6-3, with second seed and reigning Australian Open champion Sofia Kenin also taken the distance in a 5-7 7-5 6-2 win over Jessica Pegula, as Nadia Podoroska dug deep to down Petra Kvitova 5-7 6-1 7-6 (9-7).

With Barty now set to face Shelby Rogers, Danielle Collins awaits Williams having impressively defeated third seed Karolina Pliskova 7-6 (7-5) 7-6 (7-3), while Garbine Muguruza overcame Anastasia Pavlyuchenkova 6-1 6-2 to set up a meeting with Kenin.

In the Gippsland Trophy, the top three seeds all dodged upsets, with two-time grand slam winner Simona Halep, 2019 Australian Open victor Naomi Osaka and 2018 Tour Finals champion Elina Svitolina safely navigating through the last 16.

Fifth-seeded Briton Johanna Konta failed to convert two match points as she succumbed to a 4-6 7-6 (12-10) 7-6 (7-4) defeat to Irina-Camelia Begu.

Meanwhile, at the Grampians Trophy there were wins for Anett Kontaveit, Jennifer Brady and Angelique Kerber.

Daniel De Silva scored the winner as Central Coast Mariners came from two goals down to beat 10-man Melbourne City 3-2 and go top of the A-League on Wednesday.

City took the lead when Adrian Luna steered Craig Noone's delivery home with an exquisite first touch and in the 31st minute Jamie Maclaren dinked a brilliant finish over Mark Birighitti to put the visitors in control at Central Coast Stadium.

The Mariners pulled one back before half-time, though, Jaden Casella tapping in his first A-League goal after being teed up by captain Matt Simon.

Simon was making his 200th A-League appearance for the Mariners and, after drawing a foul from Nathaniel Atkinson in the box, he drilled the resulting penalty into the bottom-left corner to restore parity.

The hosts' chances of staging an unlikely turnaround were boosted by Kerrin Stokes receiving a second yellow card in the 60th minute, and De Silva got the job done with a thumping finish 10 minutes from time.

The Mariners moved three points clear of Brisbane Roar at the summit, though they have played two games more. City, runners-up in last season's Grand Final, sit eighth after a third defeat of the season.

Joao Felix has tested positive for COVID-19, adding to Diego Simeone's problems ahead of Atletico Madrid's meeting with Celta Vigo.

Portugal international Joao Felix is self-isolating at home, as team-mates Mario Hermoso and Yannick Carrasco have been doing since Friday.

A brief Atletico statement read: "Joao Felix has tested positive for COVID-19. The striker is isolating at home, in compliance with the health authorities' guidelines and LaLiga protocols."

Simeone's men have a 10-point advantage at the top of LaLiga and welcome Celta to the Wanda Metropolitano on Monday. They then travel to Granada the following Saturday.

Hermoso and Carrasco are unlikely to return for the meeting with Celta, while Kieran Trippier will be absent due to suspension.

Joao Felix marked his return to the starting line-up against Valencia on January 24 by scoring his first goal in almost two months and setting up another, leading Atletico from a goal down to a 3-1 victory.

The 21-year-old has been left out of the first XI eight times in LaLiga this season and Atletico have won all those matches.

However, when Joao Felix starts they average two more shots (12.1 to 10.0) and their goals-per-game ratio improves from 1.9 to 2.3.

Kyrie Irving used a lacklustre defensive display against the Washington Wizards as motivation to lead the Brooklyn Nets to success against the Los Angeles Clippers on Tuesday.

The Nets fell to a 149-146 defeat to the Wizards on Sunday, with Irving claiming he "couldn't guard a stick" after Russell Westbrook poured in a game-high 41 points.

The former Boston Celtics point guard responded with a strong display on both ends of the floor against the Clippers, scoring 39 points in a 124-120 success at Barclays Center.

"We just needed to respond, every single night is going to be different. I'm just trying to give what is needed on both ends of the floor," said Irving, who had two blocks and one steal.

"Like I said the other night, I took that personally, just not being able to guard anyone. Tonight I gave up a few drives but I feel like defensively as a team, including with my effort, we just matched it.

"We knew they were gonna bring it, so it was just an exciting game. Great competition for some of the top players in the world to go against each other on TV, so grateful to give the fans what they want."

Irving led a 13-0 run that included buckets from Kevin Durant and James Harden – who became the eighth player in NBA history to reach 50 career triple-doubles – as the Nets established a 10-point lead with four minutes remaining in the fourth quarter.

The Clippers managed to bring the difference back to one but were unable to stop Brooklyn improving to 14-9 on the season.

"Late in games any coach in America wants the ball in their best players' hands," said Durant, who reached 500 points for the Nets in just his 17th game – a franchise record and the second-best mark all-time for a player on a new NBA team, after Wilt Chamberlain for the Warriors in 1959-60 (14 games).

"We've got three guys who are unselfish and know how to play, and I think we made the right plays down the stretch, especially Kyrie and James, controlling the ball.

"I felt like when those guys [have] got it on top, they've got the defense at their mercy so we've got to continue to be on the same page late in games."

On the Nets' late-game defense, he added: "You're down 10, you're shooting the ball with no conscience, they went in. Sometimes we got hands up on stuff, we gave up an and-one, but it wasn't anything easy I'll tell you that.

"I think they earned every point late in the game and that's what we want at the end of the day."

Head coach Steven Nash was proud of Brooklyn's defensive improvement against the team that entered the game with the best record in the league.

"We have the luxury of offensive talent, but we also have to defend. That is a difficult team to defend and we did a great job," said Nash.

"You know it is kind of tricky when the teams are constantly taking way more shots than you are.

"We'll keep cleaning up and we'll keep getting better. When they put up the effort that they did tonight, we'll be tough to beat."

Israel Folau is no longer wanted by St George Illawarra Dragons after the NRL club confirmed it had ceased discussions to sign the former Australia international.

Folau, whose Rugby Australia contract was terminated in 2019 for a "high-level breach" after the 31-year-old posted hell awaits "drunks, homosexuals, adulterers, liars, fornicators, thieves, atheists and idolaters" on Instagram, plies his trade with Super League outfit Catalans Dragons.

But St George Illawarra had been looking to lure him back to his home country, with the club having approached the NRL over the matter.

However, a brief statement released by the club on Wednesday revealed the chase was now at an end.

"While the Dragons did enquire about signing Folau, the club can confirm that such discussions have now ceased," it read.

Folau's move to Catalans in January last year prompted widespread criticism, with head coach Steve McNamara confessing: "We knew it would be controversial."

Bournemouth have sacked manager Jason Tindall after a four-match losing streak put a dent in their hopes of making an instant return to the Premier League.

The Cherries suffered a 2-1 defeat at home to relegation-threatened Sheffield Wednesday on Tuesday, leaving them eight points adrift of the top two in the Championship.

Tindall had two spells apiece as a player and assistant manager at the south-coast club before taking the top job when Eddie Howe left in August.

In a statement confirming the 43-year-old's dismissal, Bournemouth said: "It is a decision which has not been taken lightly, given Jason's outstanding commitment to the club as a player, assistant manager and manager.

"However, recent performances and results have fallen well below the board's expectations."

Bournemouth dropped into the second tier after finishing one point short of safety in the 2019-20 Premier League campaign, ending a five-season run in the top flight.

Paul George felt it was "disrespectful" of the referees to only give him one free throw attempt during the Los Angeles Clippers defeat to the Brooklyn Nets on Tuesday.

Six-time All-Star George was sent to the line for the first and only time when he got an and-one play on Landry Shamet midway through the fourth quarter.

The Nets' superstar trio of Kyrie Irving, Kevin Durant and James Harden combined to go 16-of-16 from the stripe, while Kawhi Leonard was 8-of-9.

"I mean, I think it was disrespectful that I had one free throw attempt today. I am going to leave it at that," said George, who finished the game with 26 points.

The last time George scored as many points with one or zero free throw attempts was in January 2018 against the Denver Nuggets, when he had 43 without a single foul shout.

He continued: "The amount of plays I initiated or created contact, and to get sent to the line one time. Definitely plays I'm gonna have sent in."

Brooklyn responded to George's made free throw with a 13-0 run. A Durant jumper was followed by a three-pointer from Irving, who hit another after adding two points in between.

A step back three from Harden put the Nets in a comfortable position with four minutes and 10 seconds remaining, and although the Clippers got back within one they were unable to avoid a 124-120 defeat at Barclays Center.

Irving scored a game-high 39 points, Harden had a triple-double of 23 points, 11 rebounds and 14 assists, and Durant poured in 28 points to make franchise history.

Durant reached 500 points for the Nets in just his 17th game, making him the second-quickest to hit that mark with a new team in the NBA. Only Wilt Chamberlain managed it in less time with the Warriors in 1959-60 (14 games).

"I mean as good a defense we played all night, the fact of the matter is they have some of the best iso players in the world: Kyrie, James and KD," said George.

"I thought there was a stretch where we played great defense, were in their face, and it was almost like each one of them took turns in making a shot.

"They're just tough to guard, they're super confident in their shotmaking ability, [and] defense I thought couldn't be any better on some of those possessions."

Head coach Tyronn Lue felt George let not getting calls from the officials have too much of an impact on his production during the early stages.

Asked if he felt that affected George's rhythm, Lue responded: "Yeah, but it shouldn't. We talked about playing through the officiating, no excuses.

"Some calls should have gone his way but they didn't, and so we've just got to keep playing. I thought he got his composure back in the second half and he played through it, so it's a learning lesson for us."

The Brooklyn Nets' stars delivered in a win over the Los Angeles Clippers, while Fred VanVleet made history for the Toronto Raptors.

The Nets' 'Big Three' – Kevin Durant, James Harden and Kyrie Irving – led Brooklyn past the Clippers 124-120 in the NBA on Tuesday.

Harden posted a triple-double of 23 points, 14 assists and 11 rebounds, while Irving had a game-high 39 points and Durant finished with 28.

With his 50th career triple-double, Harden became the eighth player in NBA history to achieve that mark, joining Oscar Robertson (181), Russell Westbrook (151), Magic Johnson (138), Jason Kidd (107), LeBron James (95), Wilt Chamberlain (78) and Larry Bird (59).

The Nets improved to 14-9 with victory over a Clippers (16-6) side also expected to contend come season's end.

Clippers star Kawhi Leonard had 33 points and Paul George chipped in with 26.

VanVleet dominated with a record-breaking 54 points in the Raptors' 123-108 win over the Orlando Magic.

The guard broke DeMar DeRozan's franchise record of 52 points in a game.

VanVleet was 17-of-23 from the field and 11-of-14 from three-point range, while adding three rebounds, three steals and three blocks.

He became the first player in NBA history to have 50-plus points, 10-plus three-pointers made, three-plus blocks and three-plus steals in a game, as per Stats Perform. He was also the first guard with 50-plus points, three-plus blocks and three-plus steals in a game since Michael Jordan in April 1987.

Curry magic not enough, Sabonis stars

Stephen Curry made seven three-pointers and had 38 points and 11 rebounds, but the Golden State Warriors went down to the Boston Celtics 111-107.

Jayson Tatum led the Celtics with 27 points and nine rebounds.

Domantas Sabonis' double-double of 32 points and 13 rebounds saw the Indiana Pacers past the Memphis Grizzlies 134-116.

Damian Lillard finished with 32 points as the Portland Trail Blazers beat the Washington Wizards 132-121. Bradley Beal had 37 points for the Wizards.

Griffin below his best

Blake Griffin struggled from the field, shooting four-of-13 for 11 points in 29 minutes in the Detroit Pistons' 117-105 loss to the Utah Jazz.

Melo moves

Carmelo Anthony posted 21 points off the bench in the Trail Blazers' win. He moved up to 13th on the all-time scoring list.

Tuesday's results

Toronto Raptors 123-108 Orlando Magic
Brooklyn Nets 124-120 Los Angeles Clippers
Indiana Pacers 134-116 Memphis Grizzlies
Portland Trail Blazers 132-121 Washington Wizards
Boston Celtics 111-107 Golden State Warriors
Utah Jazz 117-105 Detroit Pistons

Pacers at Bucks

The Pacers (12-9) will aim for a second straight win when they take on Giannis Antetokounmpo (averaging 27.3 points, 11 rebounds and 5.7 assists per game this season) and the Milwaukee Bucks (12-8) on Wednesday.

Manchester United matched their own record for the biggest home win in Premier League history as Southampton suffered the unprecedented ignominy of 9-0 defeats in consecutive seasons.

Ralph Hasenhuttl's men saw their outing at Old Trafford unravel from the moment Alexandre Jankewitz was shown a second-minute red card for an ugly lunge on Scott McTominay.

Aaron Wan-Bissaka began the rout and efforts from Marcus Rashford and Edinson Cavani either side of a Jan Bednarek own goal made it 4-0 at half-time.

Anthony Martial and McTominay made it 6-0 inside the final 20 minutes before a Bruno Fernandes penalty, Martial's second and a closing goal from Daniel James left Southampton – who also saw Bednarek sent off – in an unsightly heap.

From nine goals to nine men, Arsenal had David Luiz and Bernd Leno dismissed as they lost 2-1 at Wolves.

That scoreline was repeated in victories for Sheffield United and Crystal Palace that could have repercussions at the bottom of the table.

Manchester United 9-0 Southampton: Record-equalling joy and despair at Old Trafford

James' goal deep into stoppage time meant United won 9-0 for the first time since thrashing Ipswich Town in March 1995. It is only the third instance of this scoreline in the Premier League, following Southampton's thrashing on home turf against Leicester City in October 2019.

This fixture is not always anything like as kind to United. In fact, they have won home and away against Saints for the first time since 2012-13 – the last time they lifted the title.

Southampton's fourth consecutive Premier League defeat is also their biggest ever away loss in any competition.

United's efforts to share the goals around, with only Martial hitting a brace, means they are the second side to have seven different scorers in a Premier League match following Chelsea against Aston Villa in December 2012.

Ole Gunnar Solskjaer has seen his side utterly transform their home performances. They won only one of six at Old Trafford at the start of this league season, scoring three times. A run of four wins out of five, with one defeat, has yielded 19 goals.

The late flurry was aided by Bednarek adding a red card to his own goal, while it could have been so different were it not for Jankewitz's rash tackle. The teenager is the first player to be sent off on his first Premier League start since Serge Aurier for Tottenham in September 2017 and the fourth man to be dismissed inside two minutes in a Premier League game.

Wolves 2-1 Arsenal: David Luiz and Leno leave Arteta's men short

Arsenal took a deserved lead at Molineux through Nicolas Pepe, who now has three goals in his past four league starts – as many as he managed on his previous 16 starts.

Mikel Arteta says he will appeal David Luiz's punishment but the Brazilian defender's foul on Willian Jose means he has been sent off three times and conceded six penalties since his Arsenal debut in August 2019, more than any other player in the division during that time.

Ruben Neves converted from the spot before fellow Portugal midfielder Joao Moutinho hammered in a fabulous 30-yard effort. Very much a collectors' item, it was the first home goal of his Wolves career at the 61st attempt.

When Leno charged from his area to handball in a wretched misjudgement, Wolves' first league double over Arsenal since 1978-79 was virtually assured and the Germany international became the second Gunners keeper to be sent off in the Premier League – and the first since David Seaman against West Ham back in 1993.

Whether largely down to indiscipline or misfortune, Arsenal have been shown nine red cards since Arteta took charge on Boxing Day 2019 – six more than any other side.

Sheffield United 2-1 West Brom: Blades sharpen survival chances

Bottom club Sheffield United are now just a point behind West Brom in 19th, even though they fell behind to Matt Phillips' close-range finish before half-time.

Phillips has now found the net in each of the past 13 seasons in English league football, a run that goes back to 2008-09.

Jayden Bogle brought the hosts level before captain Billy Sharp stepped up to net another crucial goal.

Since Chris Wilder's first game in charge of United in August 2016, Sharp has scored 76 goals in all competitions – 44 more than any other Blades player during that period.

Sam Allardyce's much-vaunted reputation for making his teams hard to beat is not doing West Brom much good at the moment. The Baggies have conceded 26 goals in nine Premier League games under the ex-England boss, as many as they let in during 13 matches under Slaven Bilic this term.

Newcastle United 1-2 Crystal Palace: Eagles soar clear of trouble

Newcastle remain eight points above the drop zone but are now seven shy of Palace, despite enjoying a dream start.

Jonjo Shelvey's long-ranger after 71 seconds was the quickest goal the Eagles have conceded in a Premier League match since Ian Taylor scored for Aston Villa inside a minute in March 1998.

Roy Hodgson's side had not won away from home after conceding first since overcoming West Ham in October 2019, drawing two and losing 12 of such games since.

But Jairo Riedewald's venomous hit saw them level in style as he ended a run of 13 games without a goal in the Premier League.

Gary Cahill then became Crystal Palace's oldest ever goalscorer in the Premier League at 35 years and 45 days. He is also the oldest Englishman to score in the Premier League at St James' Park since Alan Shearer last did so.
