Novak Djokovic continued his perfect record at the ATP Cup to help Serbia beat Canada in their opening tie.

The world number one won all eight of his rubbers in the 2020 tournament and made a fine start to this event by battling to a 7-5 7-5 win over Denis Shapovalov in Melbourne.

Milos Raonic had earlier put Canada in front when he beat Dusan Lajovic 6-3 6-4, meaning Djokovic had to return for a decisive doubles clash alongside Filip Krajinovic. 

The Serbians prevailed, winning 7-5 7-6 (7-4) against Shapovalov and Raonic.

"Filip Krajinovic was the key," Djokovic said after the doubles triumph extended his undefeated run to 10. 

"The way he played is phenomenal. He came out with very solid returning. He found his serve, great rhythm. He just played some really key shots in the second set when we needed it the most."

Of his singles win, Djokovic added: "It was a very close match. Playing Shapo is always a great challenge on hard courts. 

"He's such a dynamic, explosive player; very talented. I thought we played on a very high level, so I'm really pleased with how I've started the season.

"This is the best way to kickstart the season, playing for your country.

"We don't get to see crowds in the tennis stadiums these days so much, so it's definitely a blessing. I'm really grateful to see you guys here in the stands."

SPAIN WIN WITHOUT NADAL

Defending champions Spain were without Rafael Nadal for their tie against Australia, but they still prevailed.

Pablo Carreno Busta had few problems seeing off John Millman 6-2 6-4.

And Roberto Bautista Agut ensured the tie was won before the doubles by emerging triumphant in an entertaining encounter with Alex de Minaur, which the Spaniard won 4-6 6-4 6-4.

Nadal, who is battling a back problem, hopes to return on Thursday when Spain take on Greece.

Elsewhere, Austria fell to a 2-1 loss against Italy, as US Open champion Dominic Thiem struggled.

After team-mate Dennis Novak had superbly beaten Fabio Fognini, world number three Thiem fell to a surprise 6-2 6-4 loss against Matteo Berrettini, with Austria going on to lose the decisive doubles.

Andrey Rublev and Daniil Medvedev beat Guido Pella and Diego Schwartzman respectively as Russia produced an impressive performance to beat Argentina.

Elsewhere, at the Murray River Open, Nick Kyrgios made a winning start to his comeback after a year out of action.

He did not have it easy against the unheralded Frenchman Alexandre Muller, but salvaged a 3-6 6-4 7-6 (7-4) victory to book a second-round meeting with fellow Australian Harry Bourchier.

Dustin Poirier wants a shot at the lightweight title in his next bout and is unsure if the UFC would agree to that as part of a trilogy fight with Conor McGregor.

Khabib Nurmagomedov still holds the lightweight belt with the UFC trying to lure him out of retirement, though Poirier has taken to declaring himself the champion in the meantime.

The 32-year-old won the interim title in April 2019 but was submitted by Khabib in a unification fight at UFC 242.

Poirier put himself in pole position for a shot at the undisputed crown by beating McGregor, who won their first fight in September 2014, by TKO at UFC 257 in January.

Both are open to a third fight, but Poirier has his eyes on the title and does not think another meeting with McGregor would provide that at the moment.

Asked if he would fight McGregor for the lightweight title, Poirier told ESPN: "I'm not sure if the UFC would do that.

"Why wasn't that one for the belt? Politics? We're chasing Khabib? What's going on here?

"I have no clue what direction [the UFC is going to] move in. Obviously [Justin] Gaethje's coming off a loss too, then there's [Michael] Chandler and [Charles] Oliveira. I need to go and look at the rankings to see the order we're in now.

"It's 1-1 [with McGregor]. I knocked him out; he knocked me out. The rubber match, it does make sense."

He added: "Who else has put the resume together that I have in my last six, seven fights, whatever it has been?

"Also beating Conor, a two-weight world champion, adds another former world champion to the list of guys I've taken out. I think I'm most deserving to be in a title fight out of all these guys, but I don't know who it's going to be against."

The 2021 Major League Baseball season will start as scheduled after players rejected a proposal to delay and shorten the campaign due to the coronavirus pandemic.

It was proposed that the start of the season be pushed back from April 1 to April 29 and the number of games each team must play be cut from 162 to 154.

However, the MLB Players Association (MLBPA) rejected the offer, meaning spring training and opening day will go ahead as initially planned if an agreement on health and safety protocols can be reached.

"On the advice of medical experts, we proposed a one-month delay to the start of spring training and the regular season to better protect the health and safety of players and support staff," read an MLB statement.

"A delay of the season would allow for the level of COVID-19 infection rates to decrease and additional time for the distribution of vaccinations, as well as minimising potential disruptions to the 2021 season that currently face all sports.

"The offer included starting the regular season on April 29th and playing a 154-game schedule that would pay players in full as if playing 162 games. We also proposed two changes from the 2020 season that were overwhelmingly popular with our fans – for this season only, featuring a modified expanded postseason (seven teams per league) and the universal designated hitter rule.

"This was a good deal that reflected the best interests of everyone involved in the sport by merely moving the calendar of the season back one month for health and safety reasons without impacting any rights either the players or the clubs currently have under the Basic Agreement or Uniform Player's Contract for pay and service time.

"In light of the MLBPA's rejection of our proposal, and their refusal to counter our revised offer this afternoon, we are moving forward and instructing our clubs to report for an on-time start to spring training and the championship season, subject to reaching an agreement on health and safety protocols.

"Our 2020 season taught us that when the nation faces crisis, the national game is as important as ever, and there is nothing better than playing ball. We were able to complete a 2020 season through Herculean efforts and sacrifices made by our players, club staff and MLB staff to protect one another. We will do so again, together, as we work towards playing another safe and entertaining season in 2021."

A release from the MLBPA said: "Late last week, the MLBPA for the first time this offseason received a proposal from MLB to delay spring training and opening day by approximately one month.

"Under the proposal, the end of the season would be delayed one week, the regular season would be shortened to 154 games and all 30 teams would be required to play several doubleheaders. Players would also be required to accept previously rejected proposals that link expanded playoffs with expansion of the designated hitter.

"Although player salaries would not be initially prorated to a 154-game regular season, MLB's proposal offers no salary or service time protections in the event of further delays, interruptions, or cancellation of the season.

"The MLBPA executive board and player leadership reviewed and discussed the owners' proposal throughout the weekend and today [Monday]. The clear-cut result of these deliberations is that players will not accept MLB's proposal, will instead continue preparations for an on-time start to the 2021 season, and will accept MLB's commitment to again direct its clubs to prepare for an on-time start. 

"We do not make this decision lightly. Players know first-hand the efforts that were required to complete the abbreviated 2020 season, and we appreciate that significant challenges lie ahead. We look forward to promptly finalising enhanced health and safety protocols that will help players and clubs meet these challenges."

Roger Federer is aiming to make his return to the ATP Tour at the Qatar Open, while Rafael Nadal is contending with a back injury with less than a week until the Australian Open.

Swiss maestro Federer has not played since losing in the semi-finals at Melbourne Park to Novak Djokovic in 2020 having undergone knee surgery last year.

The 20-time grand slam champion opted not to play in Australia this year but is aiming to return in Doha in March.

"I want to celebrate great victories again. And for that I am ready to go the long, hard road," Federer, a three-time champion at the tournament, said in an interview with SRF.

"I wanted to make my comeback at a smaller tournament so that I wasn't fully in focus and where the stress is also a little less."

Federer said it "hurts" to miss out in Australia but still has lofty ambitions at Wimbledon, the Olympics and the US Open in 2021, while saying he will attempt to play on clay this year.

"I'll try to play on clay again. The whole thing, of course, with regards to Halle, Wimbledon, the Olympics and the US Open," he added.

Federer's on-court rival Nadal matched the Swiss for most grand slam singles titles won by a male player after winning the French Open last year.

But his chances of going one better may be hindered by a back issue that forced the Spanish great to sit out his country's ATP Cup opener against Stefanos Tsitsipas on Tuesday.

"Hi all, we have decided with #TeamSpain and my team, to not play today the first match of the @ATPCup here in #Melbourne since I have a stiff low back. Hopefully I'll be better for Thursday," Nadal posted on Twitter.

LeBron James is delighted to see fans back in the building despite getting into an altercation with spectators sitting courtside during the Los Angeles Lakers' road win at the Atlanta Hawks.

ESPN reported four people were ejected by the Hawks following the incident late in the fourth quarter of the Lakers' 107-99 victory at State Farm Arena.

A woman later posted on social media claiming she got involved after her husband and James exchanged words. Cameras showed a woman involved in the argument with her mask pulled below her chin, something not allowed with rules in place amid the ongoing coronavirus pandemic.

Referees halted the game and security personnel were called over, but James looked to cool the incident when talking after the contest, which was attended by 1,341 fans.

"At the end of the day, I'm happy fans are back in the building," said James.

"I miss that interaction. I need that interaction, we as players need that interaction. I don't feel like it was warranted to be kicked out."

James, who had 21 points, nine assists and seven rebounds, suggested alcohol may have been an influence in the incident.

He added: "They might have had a couple drinks, maybe and they could have probably kept it going during the game, and the game wouldn't have been about the game no more, so I think the referees did what they had to do.

"I love our fans. Laker Nation and everybody else that's against Laker Nation. It just feels better.

"Fans in the stands is just, it's just better. It's better for everybody. Especially on the last game of a 14-day road trip."

Lakers head coach Frank Vogel suggested the incident perhaps exposed a problem with having fans in attendance, especially when the woman lowered her mask.

"It certainly exposed something with regard to having fans in the pandemic," Vogel said.

"You obviously can't have fans taking their masks down and shouting at our players with the virus out there during these times."

Anthony Davis concurred but like James is happy to see fans back.

"With COVID going on, we obviously can't have that [masks being pulled down]. We want to make sure we all can be safe," Davis said.

"We love having fans at the game. Whether we're home or away, it just brings back the game that we love, that joy from the fans and the support.

"Whether it's 500 people or 1,000, 1,500, whatever it is, it's always enjoyable to play in front of a crowd."

Andrea Pirlo exudes composure and shows little emotion on the sidelines but that is only half the story according to Christian Vieri, who believes the "fun" first-year head coach can lead Juventus to a clean sweep of silverware in Turin.

Eyebrows were raised when nine-time reigning Serie A champions Juve turned to club great but unproven coach Pirlo following the dismissal of Maurizio Sarri at the end of the 2019-20 season.

Pirlo had only re-joined Juve as Under-23s head coach a week earlier before the Bianconeri gave the 41-year-old his first senior coaching role at the Italian powerhouse, where he won four Scudetto titles among other honours during an illustrious playing career.

While there have been teething issues and a stuttering start, World Cup winner Pirlo has already tasted success for the first time as a coach in the Supercoppa Italiana, while Juve are seven points off the pace in Serie A, through to the Champions League last 16 and preparing for Tuesday's mouth-watering Coppa Italia semi-final against Inter.

Vieri spent time with Pirlo at Inter and within the Italy national team and he talked up the playful side of his former team-mate – who remains in the hunt for a Serie A, Champions League and Coppa Italia treble in his maiden season at the helm.

"Listen, Juventus can win anything every year. They have a fantastic side," Vieri, who won the 1997 Scudetto with Juve before later joining Inter for a then-world record fee in 1999, told Stats Perform News. "When you have Cristiano Ronaldo with you, you always start 1-0.

"Pirlo is a fun guy. He is the opposite of what everyone sees. He is a fun dude, he takes the p*** out of you the whole day.

"Of course, everyone is different on TV, right? He is calmer. You never see him go crazy. He is the opposite of [Antonio] Conte. You see Conte, it's like he is playing.

"It's his first experience. He is having a good time. He won a trophy already. You win games and lose games, it's part of coaching. Maybe lose more games than win, some coaches do that. But he is happy coaching, that's what he wanted to do.

"He has an amazing team. He can everything this season. Let's see what happens. Nine years in a row winning the Scudetto, of course, sooner or later you will lose it because motivation-wise, you can't have that motivation every year."

Inter will host Juventus in the first leg of their Coppa Italia semi-final at San Siro on Tuesday.

It will be a chance for Juve to avenge their previous Derby d'Italia loss to Inter, who outclassed Pirlo's men 2-0 in Serie A action on January 17.

Inter – boasting the likes of Romelu Lukaku, Lautaro Martinez, Achraf Hakimi and Nicolo Barella – are widely viewed as the favourites to put an end to Juve's domestic dominance, which dates back to 2011.

The Nerazzurri, where Vieri spent six successful years, are second and only two points behind leaders Milan through 20 Serie A matchdays.

But Italian great Vieri believes Juve remain the "strongest team in Italy" due to their depth.

"They have 23 fantastic players," the 47-year-old added. "They have a big, long bench. [Paulo] Dybala stays on the bench, [Juan] Cuadrado stays on the bench, Arthur stays on the bench… they're fantastic players.

"I don't think the other benches are as strong as Juve's. I think Juve are still the strongest. But motivation wise, you can't win forever.

"Inter have a fantastic team this season. Hakimi, [Arturo] Vidal, [Ashley] Young, [Alessandro] Bastoni, they're all good players. They're solid, more solid defensively than three-four months ago. Up front they're fantastic. Anyone can win.

"Against Juve, Inter played fantastically [in Serie A]. Technical wise, physically. Let's see what happens in the semi-final."

NBA champions the Los Angeles Lakers beat the Atlanta Hawks 107-99 behind a dominant final quarter from LeBron James.

James posted 21 points, nine assists and seven rebounds against the Hawks on the road, having only managed nine points through the first three quarters on Monday.

Lakers team-mate Anthony Davis scored 25 points of his own in Atlanta, where a small crowd were granted access to attend.

James was involved in a brief verbal confrontation with a female fan during the fourth quarter.

Trae Young (25 points and 16 assists) and Clint Capela (16 points and 13 rebounds) both had double-doubles for the beaten Hawks.

Meanwhile, the Houston Rockets tied an NBA record after defeating the Oklahoma City Thunder 136-106.

The Rockets knocked down 11 three-pointers in a 48-point opening quarter to match a league record away to the Thunder.

Eric Gordon (25 points) and DeMarcus Cousins (17 points) each finished with five three-pointers, John Wall (18 points) and Danuel House Jr. (13 points) nailed four from beyond the arc, while Victor Oladipo (15 points) made three of his own.

Monk cools Heat

Malik Monk starred off the bench, posting a career-high 36 points as the Charlotte Hornets outlasted the Miami Heat 129-121 in overtime.

De'Aaron Fox had 38 points, including 17 straight Sacramento points during the final seven minutes, to lead the Kings past the New Orleans Pelicans 118-109. It capped a night which saw seven Kentucky players score 20-plus points in the NBA – Fox, Monk, Davis, Keldon Johnson (25), Devin Booker (24), Bam Adebayo (23) and Julius Randle (23). According to Stats Perform, it is the most 20-point games by players from any single college on any single day in NBA history.

Nassir Little put up 30 points, however, the Portland Trail Blazers still suffered a 134-106 defeat at the hands of the Milwaukee Bucks.

A double-double of 23 points and 18 rebounds from Jarrett Allen inspired the Cleveland Cavaliers' 100-98 success against the Minnesota Timberwolves.

Trent struggles in Milwaukee

Gary Trent Jr. had a tough night for the Trail Blazers. In 29 minutes, he was three of 13 from the field and made just two of eight three-point attempts for eight points.

Danilo Gallinari did not fare much better for the Hawks. Gallinari finished two-of-10 from the field, while draining only two of his five shots from beyond the arc for six points.

Booker calls game

The Phoenix Suns trailed by two points at the death, but Booker nailed a clutch three-pointer with 1.5 seconds remaining to stun the Dallas Mavericks 109-108. It was Booker's fifth career game-winning shot in the final three seconds of a contest.

Clippers at Nets

In-form Western Conference leaders the Los Angeles Clippers (16-5) will put their three-game winning streak on the line against the star-studded Brooklyn Nets (13-9) on Tuesday.

Tampa Bay Buccaneers quarterback Tom Brady is aiming to surpass "idol" Michael Jordan by winning his seventh Super Bowl ring.

No player has won more Super Bowl titles or appeared in more NFL showpieces than six-time champion Brady, who will lead the Buccaneers against reigning champions the Kansas City Chiefs in Super Bowl LV on Sunday.

Chicago Bulls and NBA great Jordan also won six championship rings during his Hall of Fame basketball career.

As Brady stands on the cusp of a seventh Lombardi trophy, the 43-year-old superstar told reporters on Monday: "Michael [Jordan] is one of my sports idols.

"I think he's pretty incredible and for me it's just about being a part of great teams.

"To have the opportunity to play in this game means a lot to me. It's a lot of commitment and sacrifice by a lot of guys.

"Obviously we're one game away from the ultimate goal in this sport. I've been a part of that ultimate goal six other times so they are all different and have all meant something a little different to me. They've all been unique in their own way. 

"It would be cool to accomplish it this time, I don't compare them to the other times, those were all magical moment of my life and no one can ever take those away from me.

"Hopefully we can finish this season strong and win a Super Bowl. That's why we're here, that's why we're playing, to make for a really magical season for us."

Brady – who will go head-to-head with reigning Super Bowl MVP Patrick Mahomes in Super Bowl LV on home soil – has more playoff wins since turning 35 (17) than any other quarterback has in his entire career, per Stats Perform.

Tampa Bay's Brady became the third player all-time with three-plus touchdown passes and three-plus interceptions in a conference championship game, joining Joe Montana (1981 NFC Championship) and Mark Malone (1984 AFC Championship), after the Buccaneers topped the Green Bay Packers in the NFC decider.

The 31-26 win in Green Bay was also the fourth time Brady has thrown three-plus interceptions in a playoff game, and his teams are 3-1 in those matchups (most such wins all-time) – his sides are 0-9 when he has three-plus interceptions in a regular-season game.

It was the 20th occasion Brady has led his team to 30-plus points in a postseason game – no other player has even half that total (second is Troy Aikman with nine). Brady's teams are 18-2 in those games.

Brady will feature in his 10th Super Bowl – the next most by a player is six by Mike Lodish and Stephen Gostkowski, after the Buccaneers became the fifth team all-time to win three road games in a single postseason.

The St Louis Cardinals have acquired five-time MLB All-Star Nolan Arenado in a blockbuster trade with the Colorado Rockies.

St Louis and Colorado announced the deal on Monday, with the Cardinals sending Austin Gomber, Elehuris Montero, Tony Locey, Mateo Gil and Jake Sommers to the Rockies in exchange for Arenado and cash considerations.

The Cardinals will reportedly receive $50million in cash, new deferrals in Arenado's contract that has six years and $199m remaining, and the waiving of his no-trade clause.

Arenado signed an eight-year, $260m contract with the Rockies prior to the 2019 season but Colorado opted to deal the eight-time Gold Glove Award winner.

The 29-year-old was hampered by soreness in the AC joint of his left shoulder during the coronavirus-shortened 2020 season, tallying 46 hits, 23 runs, eight homers and 26 RBIs in 182 at-bats for the Rockies – who missed the playoffs.

Arenado was coming off a career-best .315 with 41 home runs and 118 RBIs in 2019.

A Gold Glove winner in each of his eight seasons in Colorado, where he made his debut in 2013, Arenado has amassed 1,206 hits, 649 runs, 235 homers and 760 RBIs at an average of .293 in his career.

In the postseason, the four-time Silver Slugger and four-time Platinum Glove winner has two runs, one homer and three RBIs while averaging .190 in 21 at-bats.

The Cardinals, who lost in the Wild Card Round last season, quickly become favourites to win the National League (NL) Central, which consists of the Chicago Cubs, Cincinnati Reds, Milwaukee Brewers and Pittsburgh Pirates.

Not since 2011 have the Cardinals won the World Series.

Paris Saint-Germain's Kylian Mbappe said Neymar is the centre of the club's project as he hailed the Brazilian star.

Neymar joined PSG from Barcelona in a world-record € 222million deal in 2017, but he has been repeatedly linked with a return to his former club or LaLiga champions Real Madrid.

The PSG forward pledged to remain in Paris alongside Mbappe prior to Sunday's shock 3-2 Ligue 1 defeat to Lorient.

Mbappe – who is also out of contract in 2022 – has similarly been tipped to leave PSG for Madrid amid doubts over his future but talked up his relationship with superstar team-mate Neymar.

"I've always thought that great players were made to play together - and that's clear between us two," Mbappe told France Football.

"Our roles were established when I arrived in Paris: Neymar is the centre of the project and I'm here to help him.

"[This is] because when I arrived at PSG, I was only an emerging star and I had to prove myself on the pitch."

Mbappe has scored 106 goals and set up a further 54 in 148 appearances for PSG.

Since his debut for the club on September 8, 2017, the only players in the top five European leagues to have registered more goal involvements are Bayern Munich's Robert Lewandowski (186) and Barcelona superstar Lionel Messi (206).

Neymar, meanwhile, became the first PSG player since Zlatan Ibrahimovic in 2015 to convert two penalties in the same game as the French giants fell to Lorient on Sunday.

It was only the second time in Neymar's career he has converted more than one penalty in the same game in the top five European leagues, having achieved the feat with Barca in October 2015.

"Neymar knows how to do everything," Mbappe added. "He's the best in the world.

"When he arrived in Paris, we realised everything he could do. He's not a player simply for putting on a show and dancing when you're winning 5-0. He also knows how to do spectacular things at 0-0.

"I don't know if everyone is aware, but Neymar understands everything. He has an instinct that makes him know how to do everything straight away."

Andrea Pirlo cited the 2-0 loss to Inter in January as a turning point for in-form Juventus as they prepare to face Antonio Conte's side once again, this time in the Coppa Italia. 

Arturo Vidal and Nicolo Barella scored the goals as Inter deservedly triumphed at San Siro last month, the defeat inflicting further damage on the reigning champions in their bid for a 10th straight Serie A title. 

However, since that setback in Milan, Juve have won four games in a row without conceding. That run includes lifting the Supercoppa Italiana at the expense of Napoli, as well as a Coppa Italia quarter-final success over second-tier SPAL. 

Next up in the competition is a two-legged tie with Inter and, having been second best in the previous meeting, Pirlo is confident his side learned a valuable lesson from that game.

"I want to see a team aware of their strength," Pirlo - who confirmed Gianluigi Buffon will start in goal - told the club's television channel.

"It will be the first round, because it's a 180-minute game, so tomorrow it will be important to manage it well, because it won't be decisive.  

"The match against Inter in the league taught a lot, first of all, when we are not on the right track, we are not ourselves, but from there we started with great performances.” 

As for Conte, he is wary of a repeat of what happened to Inter in the competition in the 2019-20 season, when they lost 1-0 at home to Napoli in the first leg of the semi-final. A 1-1 draw was not enough in the return fixture, meaning they were knocked out by the eventual winners. 

"You always need to be very respectful of very strong teams, and we'll certainly need to put in an excellent performance,” the former Chelsea boss told the media.

"The upcoming 180 minutes will determine who progresses, and the first match will be important. Last year, we lost 1-0 to Napoli at home and didn't manage to turn things around at the San Paolo despite playing very well. We will need to perform and try to do our best."

The Nerazzurri will be without Romelu Lukaku on Tuesday due to suspension after he received a yellow card for his part in a confrontation with Zlatan Ibrahimovic in the previous round. 

Conte, though, is confident he has enough strength in depth at the position to cover for the absence of the influential Belgian. Lukaku scored twice at the weekend against Benevento in Serie A action, taking his tally for the campaign in the league to 14 goals in 16 appearances. 

"It's not the first time that Romelu has been missing," Conte said. "We will have Alexis and Lautaro, who I'm sure will do well.  

"Romelu is feeling good, he responded on the pitch and scored two goals against Benevento. Now, he's being forced to rest due to his suspension and will work hard to be in good shape when he returns in the league."

The Italian Football Federation (FIGC) has opened an inquiry into the clash between Zlatan Ibrahimovic and Romelu Lukaku in Inter's Coppa Italia win over Milan.  

The former Manchester United team-mates were involved in a heated exchange in which Ibrahimovic appeared to tell the Belgian forward: "Go do your voodoo s***, you little donkey".  

It was suggested Ibrahimovic was referring to comments made in 2018 by Everton majority shareholder Farhad Moshiri, who said Lukaku had declined a contract extension because a "voodoo message" told him to move to Chelsea - a transfer that never transpired.  

Some accused Ibrahimovic of racially abusing Lukaku, with the Swede responding by stating on Twitter: "In ZLATAN's world there is no place for RACISM." United midfielder Paul Pogba also tweeted to say his old team-mate was "the last person I'd think of as racist".  

Both players were booked following the incident before Ibrahimovic picked up a second caution for a foul in the second half of the game.

As part of the inquest, match referee Paolo Valeri has been summoned to explain his decision to book both players in the aftermath. 

A statement read: "This morning, FIGC attorney Giuseppe Chine opened an inquiry into the verbal dispute between Zlatan Ibrahimovic and Romelu Lukaku in the Coppa Italia quarter-final between Inter and Milan on January 26. 

"As part of this inquest, Chine has decided to summon referee Paolo Valeri, who will, in the next few hours, be called upon to give his statement regarding the sanctions that were handed out to both players during the game." 

Lukaku had cancelled out Ibrahimovic's opener in the tie at San Siro before Christian Eriksen sealed Inter's progression to the semi-finals with a stoppage-time free-kick.
