Cristiano Ronaldo scored a first-half hat-trick as Juventus took out their Champions League frustration on Serie A strugglers Cagliari in a 3-1 away win.

The subject of transfer speculation after disappointing in the Bianconeri's European exit to Porto in midweek, Ronaldo came to the fore on Sunday with the second-fastest treble of his outstanding career.

The 32-minute blitz was enough to cast aside 17th-placed Cagliari, who had conceded all of their previous six Serie A goals after the break.

Giovanni Simeone struck back to cap an improved second-half display from Cagliari, but Juve comfortably eased to a third straight league win.

Federico Chiesa had already equalled his career-best tally of assists in a single Serie A campaign, and the winger nearly had a seventh of the season when he crossed for Ronaldo, whose header was deflected wide.

Juve's opener came from the resulting corner, Ronaldo powering in Juan Cuadrado's cross.

Alvaro Morata squandered a great chance 12 minutes later but made amends with a terrific ball for Ronaldo, who drew a rash lunge from Alessio Cragno and duly thumped home the subsequent spot-kick.

Having crafted Morata's wasted opportunity, Chiesa got the assist his performance deserved in the 32nd minute, his drilled crossfield pass teeing up Ronaldo to complete a perfect hat-trick with an arrowed left-footed finish beyond Cragno.

Cagliari started the second half brightly and, after some smart stops from Wojciech Szczesny, were rewarded when Simeone slammed home from a precise Gabriele Zappa cutback.

VAR deemed Joao Pedro not to have been fouled by Adrian Rabiot inside Juve's box soon after.

Chiesa just failed to turn in Cuadrado's centre to restore a three-goal advantage, but the visitors ultimately avoided any further scares to move within 10 points of leaders Inter.

Cristiano Ronaldo was destined to be at the centre of transfer speculation after Juventus were bundled out of the Champions League, according to head coach Andrea Pirlo.

The 36-year-old forward has been linked with a return to Real Madrid at the end of the season, three years after he moved to Italy.

Juventus were eliminated from the Champions League by Porto on Tuesday, with Ronaldo facing criticism from figures including Fabio Capello after the second leg.

He notably turned his back on Sergio Oliveira's free-kick that found the back of the net in extra time, which triggered much of the negative judgement.

Ronaldo also failed to score in either game against the Portuguese giants, in a tie that Juventus lost on away goals.

"He's fine, it's normal that he's disappointed with what happened the other night," Pirlo said in a news conference on Saturday.

"It's normal there are rumours after an elimination. He is the most important football personality in the world, together with [Lionel] Messi.

"But let's remember that he has always done well for us, scoring about 90 goals in 100 games. It can happen that in one match he does not score, and with him that makes for more and more fuss."

Juventus are back in action on Sunday when they have a Serie A trip to Cagliari.

Trailing leaders Inter by 10 points heading into the weekend's fixtures, Juventus can ill afford to drop points at this stage of the season.

"I have lived through many of these situations. I have won a lot and lost a lot," Pirlo said.

"I have always tried to start up again with enthusiasm after great disappointments. We start again with the desire to show that we are Juve.

"We can take the championship to the last game. It depends on us, on the goals we have all set ourselves.

"From moments of great sadness we have to bring out our best and I am convinced that we will do it tomorrow.

"It will be an important match after the elimination. It will take team spirit to play a great game."

A second coming for Cristiano Ronaldo in the Spanish capital?

After a trophy-laden spell with Real Madrid, Ronaldo made the switch to Juventus.

But Madrid's all-time leading goalscorer is reportedly keen on a second stint at the Santiago Bernabeu.

TOP STORY – RONALDO EYEING MADRID REUNION

Cristiano Ronaldo wants to return to Real Madrid, according to the frontpage of Saturday's Diario AS.

Ronaldo's future with Juventus has been placed in doubt following the club's Champions League last-16 exit.

The five-time Ballon d'Or winner, who left Madrid for Juve in 2018, has reportedly been in contact with Los Blancos for months.

ROUND-UP

- New Barcelona president Joan Laporta will offer superstar captain Lionel Messi a fresh contract in the coming weeks, reports Mundo Deportivo. The deal would include Messi – heavily tipped to join either Paris Saint-Germain or Manchester City as a free agent at the end of the season – becoming a club ambassador after retirement. Laporta is also set to push ahead with moves for Bayern Munich's David Alaba, Borussia Dortmund sensation Erling Haaland and City forward Sergio Aguero.

- City lead the race to sign Haaland, according to the Daily Mail. Haaland is a player in demand, linked with Manchester United, Chelsea, Liverpool, Juve, PSG, Barca and Madrid.

- Joao Felix is also an option at the Etihad Stadium. Cuatro claims the Atletico Madrid star is a target if Aguero leaves City.

- Le10Sport claims PSG remain in talks with Neymar over a four-year contract extension. A deal is believed to be some way off.

- Harry Maguire wants United to sign an English-speaking defender, reports The Transfer Window Podcast. The Red Devils have been linked with Madrid captain Sergio Ramos and team-mate Raphael Varane, Sevilla's Jules Kounde, RB Leipzig centre-back Ibrahima Konate and Napoli star Kalidou Koulibaly. But Brighton and Hove Albion's Ben White has emerged as a target.

- TMW Radio says Atletico could be set to make a move for Napoli midfielder Fabian Ruiz. The Spain international has been previously linked with Barca and Madrid.

Cristiano Ronaldo has been linked with a sensational return to Real Madrid and Zinedine Zidane faced questions over the Juventus star's future on Friday.

It was reported this week that Ronaldo's agent, Jorge Mendes, had contacted Madrid over a potential switch back to the LaLiga champions.

Portugal captain Ronaldo is Madrid's all-time leading goalscorer after finding the back of the net a staggering 451 times in 438 matches before joining Juve on a four-year deal in July 2018.

Madrid boss Zidane could not escape the speculation at his latest media conference as talk over the possibility of the 36-year-old rejoining Los Blancos continues to rumble on.

"We all know what he means for the club, what he did for the club," he said.

"I coached Ronaldo, he's part of the club's history, his contribution was magnificent but right now he's a Juventus footballer and he's doing very well for the club and there's not much more I can add to all the things that have been said.

"He's a Juve footballer and I have to respect the club and the player."

Madrid host struggling Elche on Saturday knowing they have no margin for error in the title race, as they trail Atletico Madrid by eight points.

Zidane says relegation-threatened Elche must not be taken lightly.

"We know in the Spanish league there are no easy games really," said the former France playmaker. "You look at the league table and it doesn't tell the whole story.

"It's a club that are down near the bottom, but they are a very good side and have put in some very good performances this season in the league.

"Now with the new manager [Fran Escriba] things have changed. We expect a tough game and we know we've got to put in a great performance if we want to take all three points and that's our aim."

Ronald Koeman only took charge of Barcelona at the start of the season, but his tenure could be brief.

With Joan Laporta back at Camp Nou as president, he is determined to make his mark.

And highly rated RB Leipzig head coach Julian Nagelsmann is reportedly fancied in Barcelona.

ROUND-UP

- Paris Saint-Germain could make a move for Juventus superstar Cristiano Ronaldo if Kylian Mbappe leaves, claims Le Parisien. Reports in Italy and Spain say Juve will sell Ronaldo at the end of the season following their Champions League last-16 exit.

- Ajax's Brian Brobbey will join Leipzig on a free transfer at the end of the season, reports Fabrizio Romano.

Juventus defender Merih Demiral has been ruled out for around three weeks with a thigh injury.

The Turkey international sustained the damage late on in Tuesday's 3-2 win over Porto, which saw Juve exit the Champions League on away goals at the last-16 stage.

Juve confirmed on Thursday that Demiral, who has been plagued by a number of injury setbacks over the past year, suffered low-grade tissue damage.

He is expected to miss 20 days, potentially ruling the 23-year-old out of Juventus' Serie A games with Cagliari, Napoli and Benevento.

Demiral is subsequently a major doubt for Turkey's World Cup qualifying triple-header against the Netherlands, Norway and Latvia later this month. 

Juve have an identical win rate with and without Demiral in Serie A this season, winning 60 per cent of their 10 games with the centre-back in their starting lineup and the same amount in the 15 games without.

He leads the way in terms of blocks per 90 minutes among Juve defenders in Serie A this term with 0.88, while only Giorgio Chiellini (3.72) has managed more clearances and headed clearances (2.29) than Demiral's 3.63 and 2.16 respectively.

However, the former Sassuolo man lacks in other areas, his 60.26 attempted passes per game some putting him some way behind Matthijs de Ligt's 76.26. 

In fact, only Gianluca Frabotta (51.16) attempts fewer passes on average than Demiral among Juve defenders to have featured more than once in the league in 2020-21.

Cristiano Ronaldo has been criticised by Fabio Capello for an "unforgivable mistake" as Juventus were eliminated from the Champions League by Porto.

The Old Lady were dumped out of Europe's elite competition on Tuesday as their 3-2 victory after extra-time in Turin saw Porto qualify for the quarter-finals on away goals with the tie level at 4-4 on aggregate.

On a rollercoaster night at Allianz Stadium, Juve were left with an uphill battle after Sergio Oliveira's 19th-minute penalty had Porto 3-1 up in the tie, before a brace from Federico Chiesa early in the second half initially spared the hosts.

That was enough to take the game to extra-time – Mehdi Taremi's sending off in the 54th minute seemingly giving Andrea Pirlo's men the edge – but an Oliveira free-kick made it 2-2 on the day and gave Juve too much to do despite Adrien Rabiot's header two minutes later.

Oliveira's decisive strike went straight through the Juve wall, with the ball going between Ronaldo's legs as he sheepishly turned his back on the effort, and former Bianconeri boss Capello was infuriated.

"Cristiano Ronaldo then cannot go in the wall like this," he told Sky Sport Italia.

"Whoever is in the wall should not be afraid of the ball, but they must be aware that they can be hit by it.

"He turned around and this is an unforgivable mistake that has no excuses. It was a very serious mistake."

Capello then castigated the so-called leaders in the Juve dressing room, pointing the finger at them for not coming out to face the media and explain themselves, with Chiesa and Matthijs de Ligt the individuals who took part in post-match duties.

"At certain moments the captain and the elders have to show their faces," he said. "Instead they sent Chiesa. They [the "elders"] showed up when they won the games."

Elimination left Andrea Pirlo's tenure with a poor outlook only worsened by their fortunes in Serie A, with the defending champions 10 points adrift of leaders Inter – even if they win their game in hand, the Old Lady will have a significant gap to claw back.

Capello now suspects the Juve hierarchy regret ushering Massimiliano Allegri out the door in 2019.

"The much-maligned Allegri won championships and made two Champions League finals and what he did was never highlighted," Capello continued.

"It was said that there was a need for a different brand of football, but when you try to do different things you often go towards things that are not always pleasant and positive."

Matthijs de Ligt was linked with Manchester United before his move to Juventus in 2019.

United have reportedly renewed their interest in the 21-year-old Dutch defender.

Could he end up in Manchester?

TOP STORY – UNITED WANT DE LIGT

Manchester United are set to target Juventus centre-back Matthijs de Ligt, according to TodoFichajes.

United were heavily linked with De Ligt before the Netherlands international swapped Ajax for Serie A champions Juve in 2019.

With United reportedly not advancing in their pursuit of Real Madrid pair Sergio Ramos and Raphael Varane, the Red Devils are eyeing De Ligt.

United have also been linked with RB Leipzig's Ibrahima Konate, Sevilla defender Jules Kounde and Napoli star Kalidou Koulibaly.

ROUND-UP

- Calciomercato reports Paris Saint-Germain are poised to offer David Alaba a €25million-per year deal in an attempt to prise the Bayern Munich star to the French capital. Out of contract at season's end, Alaba has been tipped to join Madrid. Chelsea, Barcelona and Manchester City have also been linked.

- United have been left alone in the fight to sign Aston Villa captain Jack Grealish, claims TodoFichajes. Unwilling to match Villa's valuation, City have reportedly exited the race for Grealish. The report also says United could sell Marcus Rashford to fund the move.

- Madrid stars Lucas Vazquez and Isco are wanted by Everton, according to Calciomercato. After prising James Rodriguez from the LaLiga champions, Everton are targeting another two players from the Spanish capital, though Milan and Juve are also keen.

- Diario AS reports Madrid are prioritising a move for in-demand Borussia Dortmund star Erling Haaland. Chelsea, United, City, Juve, PSG, Barca and Bayern have all been linked but Madrid are reportedly shifting their attention from Kylian Mbappe to Haaland.

Andrea Pirlo saluted the spirit of his Juventus side after they came from behind to seal a 3-1 win over Lazio in Serie A on Saturday.

The Bianconeri fell behind to Joaquin Correa's 14th-minute strike, but powered back to claim all three points thanks to Adrien Rabiot's fine strike and Alvaro Morata's second-half brace – the second of which came from the penalty spot. 

Morata's double took his goal involvement tally this season to 15 (seven goals, eight assists) – his best return in a Serie A campaign. 

The result means third-placed Juve are now seven points behind leaders Inter, having played the same number of games. 

With an eye on Tuesday's Champions League last-16 second leg against Porto, which the Portuguese side hold a 2-1 advantage in, Pirlo opted to shuffle his pack against Lazio. 

Serie A's leading goalscorer Cristiano Ronaldo started on the substitutes' bench, while Federico Bernardeschi was deployed at left-back and Danilo was used in a defensive midfield role. 

While Pirlo was disappointed with his side's sluggish start, he was pleased they were able to secure all three points after going behind for the first time since the 2-1 win over Torino in December. 

"We started badly and conceded with our poor back pass, but then there was a strong reaction from the whole team despite missing so many players," he told DAZN. 

"We didn't let our heads drop, we started to step up the tempo and that was the most important thing.

"We thought about Tuesday's game. We knew tonight was like a final, some had to play in new positions and showed great professionalism and spirit of sacrifice.

"The most important thing was the three points. Danilo was ready to work in central midfield, while Bernardeschi deserves all the compliments for playing as a left-back.

"What I liked the most was the reaction of the team, as we didn't accept being behind in such a delicate and important game, so it was that spirit I appreciated."

While he did not get on the scoresheet, Federico Chiesa was particularly impressive for the reigning champions, and the winger, who laid on Morata's first, believes something has sparked amongst his team-mates. 

"We put in a great performance, but only after conceding the opening goal, which was a mistake," he said. "We proved that we have heart, grit and I think we'll battle to the end if we play like this.

"Lazio have shown themselves to be a great team, always in the fight for the top four, so it was a big game. Having said that, they are all big if we want to win the Scudetto.

"I do what the coach asks of me. Winning the ball back comes above all from the team pressing and not just individuals. The assist was mine, but I was able to get the ball because we all worked so hard to win it back.

"After tonight, I think we're all in great shape. Something sparked within us and from now on every game is a final, whether it's in Serie A, the Champions League or the Coppa Italia."

Alvaro Morata scored twice to help Juventus to a 3-1 home win over Lazio on Saturday and keep alive their faint hopes of a 10th consecutive Serie A title.

The Bianconeri, who started with Cristiano Ronaldo on the substitutes' bench, had started sluggishly and fell behind inside 15 minutes courtesy of Joaquin Correa's third league goal of the campaign. 

Adrien Rabiot pulled them level with their first shot on target in the 39th minute, though, before Morata's quickfire double after the break – the second from the penalty spot – sealed a third win in four top-flight games. 

Andrea Pirlo's side remain in third, but have moved to within a point of Milan and seven of leaders Inter, having played the same number of games.

Cristiano Ronaldo was named on the substitutes' bench for Juventus' Serie A clash with Lazio on Saturday. 

With an eye on Tuesday's Champions League last-16 second leg against Porto, who hold a 2-1 lead from the first match, Andrea Pirlo opted to rest his talisman. 

Ronaldo is the leading scorer in Serie A this season with 20 goals and has netted four in his last three games. 

Speaking at his pre-match media conference on Friday, Pirlo hinted that 36-year-old Ronaldo might be suffering from fatigue. 

"When you play a lot of games, a day or two of rest is good," Pirlo said. "It also applies to Cristiano. 

"Now that we are short up front, he has gritted his teeth and will do it for as long as we need it. He has shown and continues to demonstrate his great professionalism."

Juve, who were 10 points behind leaders Inter ahead of kick-off, opted for Alvaro Morata and Dejan Kulusevski in attack.

His five goals in Serie A have already made him the leading American scorer in the history of Italy's top flight.

On Wednesday, Juve announced McKennie had signed a four-year contract. The €18.5m will be paid to Schalke over three years and could rise by a further €6.5m in variables.

"Weston McKennie's adventure with the Juventus shirt started very well and, as they say, the numbers don't lie," Juve said in announcing the deal.

"Wes has proven to be a very important resource for coach [Andrea] Pirlo, having already put his signature on important performances and goals. It's impossible not to think about his goal against Barcelona at Camp Nou, or the one in the Derby della Mole – his first in the black and white jersey.

"It's also important to note that he is also the youngest midfielder in this league with at least four goals, as well as the best American scorer in Serie A history. In six of the goals he has actively participated in (four goals and two assists), Juventus have always won.

"It's because of this, that as of today, he has become an outright Juventus player, with the club having made the move permanent from Schalke."
