Inter dealt a blow to Juventus' Serie A title defence and moved level on points with leaders Milan by securing a 2-0 victory at San Siro on Sunday.

Former Juve midfielder Arturo Vidal opened his Inter account with a 12th-minute header and Lautaro Martinez and Romelu Lukaku wasted chances to increase the Nerazzurri's lead.

The Bianconeri were unable to make the most of those reprieves as an emphatic finish at the end of a route-one move saw Nicolo Barella double Inter's advantage.

It was enough to give Antonio Conte a first Serie A win against Juve – the club he led to three straight Scudetti at the start of their ongoing run of dominance – and move the hosts level with Milan, who play their game in hand against Cagliari on Monday.

Cristiano Ronaldo had a goal correctly ruled out for offside but there was no doubt about Vidal's opener a minute later, as the Chile international rose above Danilo to nod Barella's delivery into the left corner.

Martinez should have doubled Inter's lead in the 23rd minute when he blazed over with the goal gaping after Wojciech Szczesny parried Lukaku's shot straight to him.

Striker Martinez again failed to hit the target with his next opening, while Lukaku placed an effort from Barella's cutback too close to Szczesny before half-time.

Inter finally had a second goal in the 52nd minute, Barella surging into a huge gap in the Juve defence and firing Alessandro Bastoni's ambitious pass into the roof of the net.

Andrea Pirlo responded by sending on Dejan Kulusevski, Federico Bernardeschi and Weston McKennie but Federico Chiesa had their best effort in the 87th minute.

Samir Handanovic kept out Chiesa's powerful drive with a superb reaction as Inter held on for an important victory.

What does it mean? Juve with ground to make up

Juve would have closed to within a point of Inter if they triumphed at San Siro, and they would have still had a game in hand on Conte's men and Milan.

However, they missed their chance to make up ground and are now seven points adrift of Inter.

They will find themselves 10 points off the top if Milan win on Monday, meaning winning their game in hand would still not put them firmly in the title picture.

Brilliant Barella

Italy international Barella put in a livewire performance against the reigning champions, creating a game-high three chances – including the assist for Vidal's goal – and producing an emphatic finish early in the second half. After managing one goal and four assists in Serie A last season, he has already scored twice and set up five more in the league in 2020-21.

Vidal sparks controversy

Pre-game footage showed Vidal embracing Giorgio Chiellini and kissing the Juve badge on his warm-up top. He may have followed it up by scoring his first Serie A goal since clinching the title for Juve in May 2015, but his muted celebrations led to much discussion about where his loyalties lie.

What's next?

Juve face Napoli in the Supercoppa Italiana on Wednesday, while Inter travel to Udinese in Serie A on Saturday.

It was as if he had never been away.

Luka Jovic has endured a dismal start to his Real Madrid career but was quickly back among the goals at Eintracht Frankfurt.

Having failed to impress in a season and a half in LaLiga following a €60million transfer from Eintracht to Madrid, Jovic headed back to Frankfurt on loan this week.

And a second debut swiftly followed, with Jovic called from the bench after 62 minutes at home to Schalke.

The game was all square at 1-1 at the time, with Andre Silva's first-half opener immediately cancelled out by Matthew Hoppe, the teenager whose hat-trick last week had secured Schalke's first win in 31 Bundesliga matches.

There was to be no second straight success for the strugglers, however, as Jovic required only 10 minutes to restore Eintracht's lead, hammering Filip Kostic's cutback into the roof of the net.

The loanee then made the points safe in stoppage time as he moved inside past Ozak Kabak to again finish right-footed and clinch a 3-1 win.

"You can tell that the air here is good for him," sporting director Fredi Bobic told Sky Sport afterwards. "The goals were top class, the whole process. That is a great art.

"I always get annoyed that I always have to sell the best players. Now he's back for a short time. That's what I'm most happy about."

With just two LaLiga goals to his name, the brace meant Jovic had netted as many times in 28 minutes back in the Bundesliga as in 32 matches for Madrid in all competitions.

The strikes came from Jovic's only two shots on Sunday, while he also completed 17 of his 18 passes in a lively display.

Serge Gnabry did not suffer a serious injury during Bayern Munich's 2-1 victory over Freiburg, Hansi Flick has confirmed.

Germany international Gnabry sat out last weekend's loss to Borussia Monchengladbach with a shin problem but played 90 minutes in the shock penalty shoot-out loss to Holstein Kiel in the DFB-Pokal on Wednesday.

He had to be replaced after 28 minutes at the Allianz Arena on Sunday but Flick is not expecting to be without the winger for a prolonged period.

"The injury is not serious, I have heard from the doctors. The muscle in his back cramped up," said the Bayern boss.

Bayern were leading when Gnabry departed thanks to Robert Lewandowski's 21st goal of the season, a record for the first half of a Bundesliga season, surpassing Gerd Muller's 20 in 1968-69.

Nils Petersen equalised for Freiburg in the 62nd minute, scoring just 28 seconds after coming on as a substitute. His Bundesliga record for goals after being subbed on now stands at 28.

But Leroy Sane, who replaced Gnabry in the first half, set up Thomas Muller - who registered his 125th top-flight assist on Lewandowski's opener - for the winner.

Sane was also on target against Kiel and Flick has been pleased to see him improving after a tough start to life with Bayern following his move from Manchester City.

"I don't like singling out individual players but he did very well and did things the team would like to see from him," said Flick.

"We saw good development. He proved today that he is always good for an assist or a goal."

With RB Leipzig having been held to a 2-2 draw by Wolfsburg on Saturday, reigning Bundesliga champions Bayern opened up a four-point lead at the summit.

Flick said: "I'm not interested in the table at the moment. We have to look at ourselves and be focused on Augsburg and Schalke as we are today.

"It's good to have achieved a four-point lead, that is extremely important. For us, only our results count."

Kemba Walker is available to play for the first time this season and could feature for up to 20 minutes for the Boston Celtics against the New York Knicks.

Walker has not appeared since the Celtics' Eastern Conference Finals defeat to the Miami Heat in Orlando last year.

The former Charlotte Hornets point guard has been working on strengthening his left knee in an attempt to avoid any further lay-offs in the remainder of the campaign.

Knee soreness contributed to Walker missing 16 of Boston's 72 regular season games in 2019-20, his first year after leaving Charlotte, so the team are hoping to avoid a repeat.

Walker was listed as questionable this week for the first time all season and was then upgraded to available on Sunday ahead of the game at TD Garden at 1300 ET.

Coach Brad Stevens subsequently confirmed Walker would have a restriction of around 20 minutes.

The 8-3 Celtics are still without Jayson Tatum, among others, due to NBA health and safety protocols in the aftermath of the team's coronavirus crisis.

Boston had three consecutive games postponed and their practices cancelled - contributing to Walker's delayed return - before beating the Orlando Magic 124-97 on Friday.

Walker averaged 20.4 points per game last season, trailing only Tatum (23.4) for the Celtics, while also contributing 4.8 assists, behind just Marcus Smart (4.9).

The 30-year-old's scoring dropped slightly to 19.6 in the postseason - putting Tatum (25.7) and Jaylen Brown (21.8) ahead of him - but he led the team in playoff assists with 5.1 per game.

Alpine have appointed Davide Brivio, the former boss of MotoGP team Suzuki Ecstar, as their racing director.

Renault announced the departure of team principal Cyril Abiteboul on Monday ahead of their rebrand to Alpine for the 2021 Formula One campaign, and now they have added new blood.

Brivio was linked to F1 after quitting his post with Suzuki Ecstar, who won the team and rider championships in last year's MotoGP season.

An Alpine statement read: "Davide Brivio joins Alpine F1 Team as racing director.

"We are delighted to confirm Davide Brivio will strengthen our team ahead of the 2021 Formula One season. His specific role and responsibilities will be announced in the coming weeks.

"Davide will report to the Alpine CEO Laurent Rossi.

"Davide joins Alpine F1 Team with a wealth of experience and success following more than 20 years in the MotoGP world championship.

"We look forward to welcoming Davide as we start the next stage of our Formula One journey."

Alpine's driver line-up is made up of Frenchman Esteban Ocon and former two-time champion Fernando Alonso.

Robert Lewandowski became the first player to hit 21 goals in the first half of a Bundesliga campaign with his opener for Bayern Munich against Freiburg.

Gerd Muller previously held the record of 20 goals, with the Bayern great having achieved the feat in 1968-69.

Lewandowski matched that haul on January 8, scoring in a 3-2 defeat to Borussia Monchengladbach.

On Sunday, in Bayern's 16th league game of the 34-match campaign, the 32-year-old overtook Muller by slotting home at the culmination of a superb Bayern move in the seventh minute.

It also brought up Lewandowski's fifth goal in his last four games against Freiburg.

Prolific in attack, it is at the other end where Hansi Flick's Bayern side have struggled this season.

Heading into Sunday's game at the Allianz Arena, the Bavarian side had 33 points – they last had as many points after 15 matches in 2017-18 - yet their 24 goals conceded after 15 fixtures was more than in any season since 1981-82 (25).

Lewandowksi scored 34 times in the league last season, six shy of Muller's Bundesliga record of 40 (1971-72), but the Poland star now looks well on course to challenge that tally.

Stefano Pioli confirmed Milan will consider adding further to their squad in January amid speculation Mario Mandzukic is set to join the club.

Mandzukic – who previously played in Serie A with Juventus – is a free agent after terminating his contract with Al-Duhail by mutual consent in July.

The Rossoneri are reportedly going to sign the Croatian striker on an 18-month deal, boosting their forward options as they look to maintain their push to win the league for the first time in a decade.

Pioli was not willing to discuss individual names at his pre-match news conference ahead of Monday's trip to Cagliari but did admit the club are ready to act if the right player becomes available.

"I don't want to and cannot comment on players that I don't have," he told the media. "I have a lot of confidence in the club and the management team. I leave that task to them.

"We know that if there is the possibility of strengthening the team, we will do it. We will be ready in January if there is the possibility of improving this group." 

Milan have already made one signing in the mid-season transfer window, midfielder Soualiho Meite arriving on loan from Torino.

"Meite makes a department that already had good solidity even more competitive," Pioli said of the new recruit.

"I really liked the move. We have combined quality and quantity. I also liked how he spoke, saying he was ambitious. To join our group, you have to be like that."

The Serie A leaders head to Cagliari without Hakan Calhanoglu and Theo Hernandez, both players currently isolating after testing positive for coronavirus.

Pioli admits it is a blow to be without the influential duo – they are also set to miss next Saturday's home fixture with Atalanta – but is confident he has the quality within his squad to cope with such situations during the course of the season.

"They are important absences, but this season is like that," the Milan boss said. "There are critical issues that can come at any moment, so we must always be prepared and attentive.

"The quality of the players that I will have available tomorrow will certainly make us have a good match.

"We are prepared, that's why I expect the players to always be ready. We can all be decisive and help the team."

A further 25 players have been forced into hard lockdown for two weeks prior to the Australian Open, tournament organisers have confirmed.

Tennis' season-opening grand slam was plunged into crisis on Saturday when it was announced 47 players would be consigned to their hotel rooms for 14 days and not eligible to practise.

Officials said the protocols were as a result of two passengers testing positive for coronavirus on a flight from Los Angeles that arrived on Friday morning, along with another passenger who flew in from Abu Dhabi.

That affected 24 players aboard the LA flight and 23 on the plane from Abu Dhabi, while another positive test for a passenger arriving in Melbourne from Doha on Saturday morning has taken the total number of players affected to 72.

A statement from the Australian Open read: "One positive COVID-19 test has been returned from a passenger on a charter flight into Melbourne from Doha which arrived at 5.30am on January 16.

"The passenger is not a member of the playing contingent and had tested negative before the flight.

"There were 58 passengers on the flight, including 25 players. All are already in quarantine hotels.

"The 25 players on the flight will not be able to leave their hotel room for 14 days and until they are medically cleared. They will not be eligible to practise."

About 1,200 players and staff have been arriving in Melbourne on sparsely populated aeroplanes ahead of the delayed Australian Open, which is due to get under way on February 8.

Speaking on Saturday, Tennis Australia CEO Craig Tiley insisted the tournament would be going ahead despite the chaos and the lack of preparation time for many of the playing contingent.

"It's not something we wanted to happen," he told The Today Show. "We were hoping every flight would be okay. We're in this situation, we have to deal with it.

"The Australian Open is going ahead and we'll continue to do the best we can possibly do to ensure those players, who are not in a great position, find it somewhat acceptable.

"We're planning on February 8, we do have that buffer time in there. We're looking forward to welcoming fans to the Australian Open.

"Ticket sales have been going well, we've got two weeks of great tennis and our intention is to continue with those dates."

England lost early wickets in their run chase but remain on course for victory in the first Test against Sri Lanka, finishing day four on 38-3 in pursuit of a target of 74. 

Having battled hard to make 359 all out in their second innings, Sri Lanka gave themselves a glimmer of hope when Lasith Embuldeniya quickly removed England openers Dom Sibley and Zak Crawley. 

The run out of captain Joe Root, who was called through for a single that was never on before falling over as he dived to unsuccessfully make his ground, left the tourists teetering at 20-3. 

However, Jonny Bairstow and Dan Lawrence steadied the nerves, seeing England through to stumps without any further setbacks. The duo will resume on day five needing a further 36 to seal the series opener. 

Sri Lanka will be left cursing their first-innings shortcomings with the bat, particularly after a second Test hundred from Lahiru Thirimanne underpinned a far-improved display second time around. 

England did remove nightwatchman Embuldeniya early but were made to work hard for wickets after that, Jack Leach the pick of the attack as he finished with figures of 5-122. 

Sam Curran eventually ended Thirimanne's defiance when the opener had 111 to his name, while the hosts were still in deficit when stand-in captain Dinesh Chandimal edged Dom Bess (3-100) to Root at first slip.  

The same bowler accounted for Niroshan Dickwella, who made 29, but Angelo Mathews proved to be a familiar thorn in England's side. 

Wicketkeeper Jos Buttler secured his first stumping in Test cricket as some smart glovework ended a lively cameo from Dilruwan Perera (24), while Mathews was the last man out midway through the final session.  

The former Sri Lanka skipper had battled for nearly six hours before Leach tempted him into a leaden-footed drive, ending his resistance on 71. England appeared frenetic at the start of their chase on a dry, turning surface, but will still be confident of completing the job on Monday.

TON-DERFUL MOMENT FOR THIRIMANNE

Thirimanne's previous Test century also came at the same venue; he made 155 not out against Bangladesh back in March 2013. The left-handed opener may not have featured in this match had captain Dimuth Karunaratne not been ruled out with a fractured thumb, but he seized his opportunity.

In total, he faced 251 deliveries and hit 12 boundaries, helping at least restore some pride for Sri Lanka after they had been dismissed for 135 on a dismal opening day.

LEACH STICKS TO HIS TASK

Leach had not played in a Test since November 2019, since when an illness and the COVID-19 pandemic has restricted him to just two first-class appearances. The left-arm spinner could be forgiven for a little rustiness, then.

However, he stuck manfully to his task during the innings, sending down 41.5 overs to claim his second five-wicket haul in Tests. His other also came against Sri Lanka, at Pallekele back in November 2018.
 

Khabib Nurmagomedov could be tempted to make a comeback if a lightweight rival impresses him at UFC 257, Dana White has revealed. 

The undefeated Khabib announced his retirement after beating Justin Gaethje to unify the lightweight division at UFC 254 last year, his first outing since the death of his father and coach Abdulmanap Nurmagomedov.

However, White raised the prospect that the Russian may return for one more bout - if he likes what he sees out of a potential opponent next week. 

That includes former foes Conor McGregor and Dustin Poirier, who meet in the main event on Fight Island. Dan Hooker and Michael Chandler do battle on the same bill, with the winner potentially coming under consideration. 

Charles Oliveira is also an option, having apparently grabbed Khabib's attention during his victory over Tony Ferguson at UFC 256 in December. 

"The thing with him is, when you make the decision to retire, I knew he made the decision under unbelievable emotional stress," White told the media after Max Holloway's victory over Calvin Kattar in Abu Dhabi. 

"His dad had died, he got hurt during that camp and couldn't train right, couldn't cut weight right. All the things he went through and then he went out and performed how he performed, then made that decision that night.  

"Listen, you're not tying anything up. Go home, spend some time with your family. Heal up, think about it. 

"Then he and I got together, and he said: 'I want to see if somebody really blows me away and impresses me next week'. 

"You've got the co-main event and the main event, while Oliveira looked awesome against Tony Ferguson - that's an interesting fight for him. 

"We will see what these guys do this weekend. I think it's fun - do you guys not want to see Khabib fight again? Hopefully, he sticks around and does one more." 

However, White made clear that Georges St-Pierre is not on the shortlist of potential opponents. 

"No, GSP never came up. He's not interested in that fight and, from what I hear today, neither is GSP. That's over," he said.

Milan have announced Hakan Calhanoglu and Theo Hernandez have tested positive for COVID-19.

The two cases were discovered following swab tests carried out on Saturday, with the club immediately informing the health authorities upon learning the results.

Both players are asymptomatic and the rest of the squad tested negative, Milan confirmed in a statement released on Sunday.

Calhanoglu and Hernandez are now isolating at home, leaving Milan without the duo for some key fixtures coming up in January.

The Serie A leaders - who have lost just once in league action this season so far - visit Cagliari on Monday, then host Atalanta at San Siro next Saturday.

There is also a Coppa Italia quarter-final clash with rivals Inter looming on the horizon, that tie due to be played on January 25. 

A-League new boys Macarthur went top of the table with a 2-1 win at Newcastle Jets on Sunday.

Loic Puyo was the star for the visitors, opening the scoring in the eighth minute before teeing up Matt Derbyshire for Macarthur's second 15 minutes later.

Sandwiched between those goals was a VAR decision that denied Jason Hoffman an equaliser for the Jets, ruling him to have strayed offside.

They did pull one back through Valentino Yuel in the 42nd minute but could not complete the comeback as the Jets' winless start to the season continued.

Macarthur are a point ahead of Central Coast Mariners at the top but have played two games more.

Shardul Thakur and Washington Sundar halted Australia's momentum before India were bowled out for 336 on a frustrating day for the hosts in the fourth Test at the Gabba.

Australia appeared on track to clean up India's batting line-up and maintain a healthy lead on day three of the final match after leaving the tourists in a perilous position of 186-6, but unheralded pair Shardul (67) and Sundar (62) put on a remarkable 123-run stand.

Josh Hazlewood's five-wicket haul finally helped put an end to India's stubborn resistance – Australia heading into their second innings with a 33-run advantage on Sunday.

David Warner (20 not out) and Marcus Harris (1 not out) saw out the remaining half-hour of play to lead Australia to 21-0 at stumps, a lead of 54 runs, as Tim Paine's side face a race against time to win the Test and reclaim the Border-Gavaskar trophy.

After rain wreaked havoc on Saturday, India resumed 62-2 in response to Australia's first-innings 369 in Brisbane, where Hazlewood (5-57) and Mitchell Starc (2-88) managed to claim the prized scalps of Cheteshwar Pujara (25) and captain Ajinkya Rahane (37) in the morning session.

Hazlewood removed Mayank Agarwal (38) with the second delivery after lunch, and the Australia star almost dismissed Rishabh Pant (23) to leave India 186-6.

But Shardul and Sundar combined to sensationally thwart Australia, who toiled tirelessly before eventually bowling out India.

Star Australia opener Warner then raced out the blocks with a quick-fire 20 runs, including three boundaries, to navigate a tricky end to the day.

India duo come to the rescue

A remarkable seventh-wicket stand kept Australia at bay and clawed India within touching distance of the hosts' first-innings total.

It was an unlikely pairing that rescued India – Sundar celebrating a half-century on his Test debut, while Shardul also raised his bat for a maiden Test fifty.

Hazlewood huffs and puffs

For the second time in the blockbuster series, Hazlewood recorded a five-for against India.

It was far from easy for Australia, but Hazlewood battled as Pujara, Agarwal, Pant, Navdeep Saini (5) and Mohammed Siraj (13) fell victim to the fast bowler.
