Cristiano Ronaldo scored twice as Juventus bounced back from their Fiorentina fiasco with a 4-1 win over Udinese at the Allianz Stadium on Sunday. 

Andrea Pirlo's side suffered a humiliating 3-0 home defeat to La Viola before the mid-season break, but they kicked off 2021 with a win that ensured the gap to Serie A leaders Milan remained at 10 points. 

Ronaldo put Juve ahead in the 31st minute with a fine strike after Udinese's Rodrigo de Paul had seen an effort ruled out by VAR. 

Federico Chiesa and Ronaldo then made sure Juve avoided going three consecutive home games without a win for the first time since 2015-16.

Marvin Zeegelaar snatched a consolation for Udinese, but Paulo Dybala had the final say in stoppage time.

Stefano Pioli lauded Milan's "heart, intensity, passion and belief" after they beat Benevento 2-0 to return to the Serie A summit despite playing for nearly an hour with 10 men.

Franck Kessie's penalty gave the visitors a first-half lead at Stadio Ciro Vigorito but Sandro Tonali's dismissal before the break left the Rossoneri up against it.

An inventive finish from Rafael Leao gave Milan a much-needed two-goal cushion early in the second half, with Gianluca Caprari missing a spot-kick at the other end for the wasteful hosts.

The win marked a fine response to Inter's 6-2 thrashing of Crotone earlier on Sunday, which had temporarily dislodged Milan from top spot.

But with his side now leading the way by a point, Pioli was full of praise.

"We showed heart, intensity, passion and belief. It's another very big victory," he told Sky Sport Italia.

"We don't let the results of our opponents put pressure on us. We put pressure on ourselves by demanding the best.

"There were a few errors, but we showed such unity to bring the result home.

"Every result is important to boost the self-belief."

Tonali was shown a red card after a careless lunge on Artur Ionita, with referee Fabrizio Pasqua upgrading his punishment from a yellow after reviewing the incident on the pitch-side monitor.

"I hugged Sandro in the locker room, he was sad about leaving the team down to 10 men," said Pioli.

"The issue with VAR is that things look much worse when slowed down compared to the dynamics of the movement, but Sandro will learn from this."

Next up for Milan is the visit of champions Juventus, though Pioli insists the result will not be pivotal in the title race.

"I think it'll be a great game between two teams in excellent shape," he said.

"I continue to say Juventus, Inter and Napoli are the strongest sides in Serie A, we just have to keep going along our path.

"It's not decisive or the passing on of any baton. Juve won the last nine titles and aren't far behind us at the moment.

"I continue to maintain we can talk about other things when we look at the table in April and if we are still in this position. Our strength has been to take it one game at a time, so we don't want to change that attitude.

"We are missing some important players, Tonali will be suspended, so it's going to be tough against Juventus. Whatever happens, it won't be decisive."

Diego Simeone called upon his Atletico Madrid players to be "constantly prepared" going into the second half of the season and warned of the "traps" that lie in store as they aim to win their first LaLiga title since 2014.

Luis Suarez scored in the 90th minute to earn Simeone's men a 2-1 victory over Deportivo Alaves on Sunday, extending their domestic winning streak to four matches and moving them two points clear of nearest rivals Real Madrid, who have played two games more.

Asked to assess his side's performance after 15 games of the season, Simeone said he expects the challenge of staying at the top of the table to be one of increasing difficulty.

"We understand that the league is complex," Simeone told reporters. "It is difficult, it has traps, you have to be constantly prepared.

"You cannot leave room to relax, because all the teams want to win. We are going to start the second round shortly and it will not be with the same calm that one perhaps plays the first round.

"The second round will be tougher, with the teams that want to save themselves and those that want to fight to enter the Europa League and the Champions League. It alerts us to the fact that the only way to play is match-by-match."

Suarez provided the assist for Atletico's opener, scored by Marcos Llorente, and the visitors were given a further boost when Victor Laguardia was sent-off after 63 minutes.

But Alaves levelled the match six minutes from time when Felipe put into his own net, only for Suarez to come up with a late winner.

Simeone expressed his satisfaction with the way his side ended the game, picking out second-half substitutes Saul Niguez and Joao Felix for praise.

"The most beautiful thing about tonight was how the game ended," said Simeone. "Not getting nervous, looking to play together.

"And the goal was a great goal, a very good play by Saul with [Thomas] Lemar and Joao, defining the nine where it should be.

"I understood that the game lasts 90 minutes and having important players also waiting for what might happen is a useful strategy.

"Obviously, Joao came on and played very well and that is what makes me happy, same as Saul - he entered very well and that makes me very happy too.

"I'm very happy for a victory that we worked very hard for."

Lionel Messi will make his 500th LaLiga appearance for Barcelona in Sunday's meeting with Huesca after returning to Ronald Koeman's starting line-up.

Messi missed Tuesday's 1-1 draw with Eibar after he was given an extended break over Christmas to nurse an ankle problem.

However, Koeman confirmed on Saturday that the 33-year-old had trained on December 30 and 31, and Messi has subsequently returned to Barca's starting XI for a landmark outing at Estadio El Alcoraz.

Messi's 500 league appearances for Barca is five short of the club-record held by Xavi, who also holds the record for all-time appearances for the Blaugrana with 767. 

Xavi's total is 17 more than Messi's current tally of 750, including Sunday's game.

The record for the most matches ever played in LaLiga is held by former goalkeeper Andoni Zubizarreta, with 662 games under his belt for Athletic Club, Barca and Valencia.

Barca make the trip to Huesca unbeaten in five league matches, but they have drawn two of their last three and enter the game 13 points adrift of leaders Atletico Madrid.

Messi was directly involved in four goals in his only previous LaLiga game against Huesca, scoring twice and providing two assists in September 2018.

Milan returned to the Serie A summit with a 2-0 win at Benevento as Stefano Pioli's side survived playing with 10 men for almost an hour.

With rivals Inter having gone top after a 6-2 thrashing of Crotone earlier on Sunday, the Rossoneri responded with a gritty victory at Stadio Ciro Vigorito.

Franck Kessie scored a first-half penalty but Sandro Tonali was dismissed before the interval to make it a potentially uncomfortable evening for the visitors.

However, Pioli's men dug deep and Rafael Leao produced a moment of magic four minutes into the second half, with Gianluca Caprari's missed spot-kick robbing Benevento of a golden chance to get back into the match.

With champions Juventus up next, Milan have a chance to send out a signal to the rest of the division that this really could be their year.

Brahim Diaz flashed an early long-range shot over the crossbar as the visitors, unbeaten in 14 on the road, signalled their intent.

Benevento were the architects of their own downfall as Milan took the lead after 15 minutes, a defensive mix-up ending with Alessandro Tuia felling Ante Rebic in the box, with Kessie coolly converting the subsequent spot-kick.

Roberto Insigne came within inches of pulling the hosts level but saw his fine strike crack the inside of Gianluigi Donnarumma's left-hand upright.

Filippo Inzaghi, who played at San Siro for over 10 years, saw his Benevento side handed a boost when Tonali was shown a red card for a careless lunge on Artur Ionita.

The home side tried to force the issue as Gianluca Caprari and Gaetano Letizia both fired off dangerous efforts, but Milan made it to the break with their lead intact. 

Pioli's charges earned the breathing space they so desperately craved courtesy of a fine goal from Leao, who beat Lorenzo Montipo to Rebic's throughball and turned smartly before lifting a pinpoint finish over the stranded goalkeeper.

Benevento's frustrations deepened when Caprari dragged a woeful penalty wide after Rade Krunic had clumsily fouled him in the area, with Milan almost adding a late third when Kessie's low shot hit the inside of the post and rolled across the line.

Bayern Munich came from behind for an eighth successive Bundesliga match as the champions overcame struggling Mainz 5-2 at Allianz Arena.

Hansi Flick's side have not taken the lead in a league game since October and might have been staring down the barrel of a second defeat of the season had Danny Latza beaten Manuel Neuer early in the second half.

Mainz had a 2-0 lead at that stage, with Jonathan Burkardt and Alexander Hack scoring in the first half, but Joshua Kimmich and Leroy Sane restored parity in the space of five minutes.

Robin Quaison struck the woodwork as 17th-placed Mainz fought back, though Bayern ultimately had too much.

Niklas Sule's deflected strike and Robert Lewandowski's double – the first of which came from the spot – settling a thrilling contest firmly in Bayern's favour.

Atletico Madrid returned to the summit of LaLiga as Luis Suarez's dramatic 90th-minute goal sealed a 2-1 win over Deportivo Alaves on Sunday. 

Diego Simeone's side dropped to second following Real Madrid's 2-0 win over Celta Vigo on Saturday, but a fourth consecutive top-flight victory restored a two-point advantage over their city rivals with still two games in hand. 

Marcos Llorente put the visitors ahead after 41 minutes with his latest long-range effort – his five from outside the penalty area since the beginning of 2020 more than any other LaLiga player. 

Alaves brushed off Victor Laguardia's 63rd-minute red card to pull level six minutes from time through Felipe's outrageous own goal, but Suarez popped up at the death to snatch a memorable win for Los Rojiblancos. 

Antonio Conte called on Arturo Vidal to improve after conceding a penalty that gave Inter brief concern in their 6-2 win over Crotone.

The Nerazzurri were ultimately comfortable victors at San Siro on Sunday as Lautaro Martinez scored their first perfect hat-trick since Mauro Icardi's against Atalanta in March 2017.

However, Inter had been level at 2-2 at half-time following Vidal's needless error.

After Martinez's first effort and a Luca Marrone own goal turned the match around following Niccolo Zanellato's Crotone opener, Vidal charged towards Arkadiusz Reca and stepped on his foot in the area to concede a penalty, which Vladimir Golemic converted.

Inter coach Conte was worried at that stage the setback might affect his side, looking to win an eighth successive league match for the first time since 2008.

But Vidal was replaced at the interval and an assured second-half display saw Martinez score twice more either side of an excellent Romelu Lukaku effort, before Achraf Hakimi completed the scoring.

Conte told Sky Sport Italia: "We did well to turn it around, then the naivety on the penalty could have created anxiety and nervousness.

"But we did well to get back on track and bring home another win.

"We had good answers today, also because we had started in the right way. Then there was this corner where they surprised us [for Zanellato's goal]."

The penalty was the only foul Vidal committed before his premature withdrawal, but he won just two of his five duels and Conte was not impressed.

"Arturo has important margins for improvement," Conte said. "He definitely needs to work. Keep your head down and keep working.

"Nobody is guaranteed a place here and he has to prove he deserves to play. He must do much better than what he is doing.

"From what we've seen so far, there are too many ups and downs, and we can't afford them. He knows this, he knows he has to train harder.

"Maybe when you play in big teams, sometimes this aspect takes a back seat. Here instead you have to raise the level, he knows that. We'll give him time."

Far more impressive was Lukaku, who created the first Inter goal for Martinez, had a hand in the next two and then scored the fourth before he hobbled off with an injury.

Having seen his outstanding number nine net his 35th goal in his 50th Serie A game, Conte will hope he does not have to face a spell without the striker.

Inter are in action again as soon as Wednesday, facing Sampdoria, and the coach was waiting to hear more on Lukaku's problem.

"He told me he had a small quadriceps strain," Conte said. "We'll see tomorrow if he's at risk for the Sampdoria game.

"We took him off straight away. I don't think it's anything serious."

Thomas Tuchel was overperforming at Paris Saint-Germain this season and did not deserve to be sacked, according to his assistant Zsolt Low.

PSG finally confirmed Tuchel's dismissal on Tuesday after days of speculation, bringing an end to his two and a half year stay at the Parc des Princes.

The German coach won back-to-back Ligue 1 titles in his two full campaigns and also won the Coupe de France, Coupe de la Ligue and two Trophee des Champions.

Tuchel also guided PSG to a maiden Champions League final in 2019-20, where they were beaten 1-0 by Bayern Munich.

But he endured a fractious relationship with sporting director Leonardo after publicly calling out the club's transfer chief over a lack of spending heading into this season.

Not helped by a number of injury issues and a lack of pre-season, PSG lost four and drew two of their opening 17 Ligue 1 matches and entered the mid-season break down in third.

However, they beat Strasbourg 4-0 in what proved to be Tuchel's last match and are just a point behind top two sides Lyon and Lille, having also advanced from a tricky Champions League group and into the last 16.

Low has outlined the details behind Tuchel's sacking and says the timing of the decision came as a shock.

"We were surprised because on December 23, after winning a match 4-0 against Strasbourg, Leonardo brought us together to say that the club was no longer counting on Thomas for the future," he told Hungarian outlet Nemzeti Sport. 

"After facing considerable difficulties in 2020, after achieving historic success with PSG, after going through the group stage of the Champions League, and with the team in full swing in the league, it made the decision very difficult to understand. 

"And the fact that we were impacted by numerous injuries throughout the season, and had to come up against COVID-19. I think that it was a great professional success to finish the year the way we did. We overperformed, that is the truth."

Tuchel appeared to criticise PSG in an interview published on the day of the Strasbourg victory, in which he also admitted managing the club was more like being a "politician".

Although surprised at the timing of the sacking, Low concedes the tense relationship between Tuchel and Leonardo meant something eventually had to give.

"We were shocked," he said. "The summer window did not go as we wanted, the main players who left after the Champions League run were not correctly replaced. 

"That created tensions between certain board members and the staff, as well as with the sporting director who was espousing management principles that were different to that of the coach.

"I don't want to delve into the details. They had different ideas in a number of domains, and the difference in viewpoint accrued over time. This led to Leonardo deciding to create a future with a different staff. 

"To be honest this situation could not have lasted. It was better to stop now, nearly at the summit, to say goodbye with a great majority of wonderful memories. Not to have followed Thomas would have gone against my values."

Low, who has previously worked as assistant boss at Salzburg and RB Leipzig, added: "Before, I had the opportunity to take the place of managers at Salzburg and Leipzig, and I did not take those opportunities. 

"When I fight alongside someone, it is for better or worse. The professional relationship between Thomas and I is extremely tight, he keeps his word, he counts on me, that is why I feel part of the successes. 

"And the failures too. I arrived at PSG upon his call two and a half years ago, I was alongside him at all times."

PSG announced Mauricio Pochettino as Tuchel's successor on Saturday, with his first game in charge away at Saint-Etienne on Wednesday.

Lionel Messi's wages are not sustainable but the superstar forward can be persuaded to stay at Barcelona with a sporting project that appeals to him, according to presidential candidate Emili Rousaud.

The six-time Ballon d'Or winner was unsuccessful in his attempt to leave Camp Nou ahead of the 2020-21 campaign, but he is now free to discuss an end-of-season transfer with clubs after entering the final six months of his contract.

He was strongly tipped to reunite with former boss Pep Guardiola at Manchester City, while Inter and Paris Saint-Germain – now coached by fellow Argentinian Mauricio Pochettino – have also been linked.

But while reiterating Messi will have to take a pay cut if he is to stay on at Barca beyond this season, Rousaud has outlined his plan to tempt the one-club man to put pen to paper on fresh terms.

"He did not want to leave the club for economic reasons. It was down to the lack of a sports project," Rousaud told Sport.

"I will look him in the eyes and say: 'Your salary is unsustainable, the club cannot pay you. But we are going to launch a project to surround you with young talent'.

Despite Barca's financial concerns in the wake of the coronavirus pandemic, Rousaud has previously outlined his intention to bring in prolific striker Erling Haaland from Borussia Dortmund if he succeeds Josep Maria Bartomeu in this month's elections.

Paris Saint-Germain's Kylian Mbappe is another possible target and Rousaud believes the prestige of playing for Barcelona could give the LaLiga giants an advantage in the transfer market.

"The market prices in which the players move now are not those of two years ago," he said. "In addition, Barca has something very important: a shirt that has a lot of weight in the world. But off course, we will not stretch the arm more than the sleeve.

"My advisor Josep Maria Minguella has spoken with [Haaland's agent] Mino Raiola to find out the conditions in which he would come and we have started talking. 

"For a player like him, being in a club like ours would give him a great showcase worldwide."

Rousaud has also vowed to attempt to bring Neymar back to Catalonia should he be elected, despite the Brazilian forward leaving Barca for PSG under a cloud that has since seen him embroiled in a court battle over an alleged breach of contract.

However, rather than condemning Neymar for leaving the club for a record €222million fee in 2017, Rousaud feels Barca only have themselves to blame for wasting the money on two players who have been blighted by injury problems.

"The money left by Neymar was invested in two players: [Philippe] Coutinho and [Ousmane] Dembele, who have not given the expected sporting result," he said. 

"And since they didn't work, we signed others. And since we no longer have cash, we started to get into debt.

"They say that Neymar humiliated us. I respect that opinion, but it left us €222million. If with that money we had signed Mbappe, maybe we wouldn't talk about Neymar anymore."

Lautaro Martinez hit a perfect hat-trick and Romelu Lukaku sparkled as Inter defeated Crotone 6-2 at San Siro to turn up the heat on Milan at the start of 2021.

Inter moved top of Serie A at least until Milan's meeting with Benevento later on Sunday as they recovered from a testing first half to ease past their struggling visitors.

It was all square at the break after Martinez cancelled out Niccolo Zanellato's opener and was in close attendance for a Luca Marrone own goal prior to Vladimir Golemic's equalising penalty.

But Martinez completed his treble following the interval, while Lukaku, involved in the first four Nerazzurri goals, was also on target and Achraf Hakimi swept in the sixth in a fifth straight win.

Only an apparent injury to the outstanding Lukaku put a slight dampener on a day that had started in laboured fashion.

Lautaro Martinez hit a perfect hat-trick and Romelu Lukaku sparkled as Inter defeated Crotone 6-2 at San Siro to turn up the heat on Milan at the start of 2021.

Inter moved top of Serie A at least until Milan's meeting with Benevento later on Sunday as they recovered from a testing first half to ease past their struggling visitors.

It was all square at the break after Martinez cancelled out Niccolo Zanellato's opener and was in close attendance for a Luca Marrone own goal prior to Vladimir Golemic's equalising penalty.

But Martinez completed his treble following the interval, while Lukaku, involved in the first four Nerazzurri goals, was also on target and Achraf Hakimi swept in the sixth in a fifth straight home win.

Only an apparent injury to the outstanding Lukaku put a slight dampener on a day that had started in laboured fashion.

Crotone struck first as a smart set-piece routine created an angle for Junior Messias to loft in a left-footed cross and find Zanellato all alone six yards out, able to head in via the post.

But Inter were level when Lukaku's excellent reverse pass set Martinez clear to fire right-footed beyond Alex Cordaz, and more fine work from the former Manchester United forward turned the game on its head.

Lukaku seized on Arturo Vidal's tackle in the midfield and fed Nicolo Barella, who was taken wide by a heavy touch but managed to cut the ball back for Marrone to stab into his own net in front of Martinez.

Vidal's next contribution was rather more rugged, however, as he stepped on Arkadiusz Reca's foot in the area to concede a spot-kick - awarded following a VAR review - which Golemic dispatched.

Martinez restored Inter's lead 12 minutes after half-time, keeping his cool on his left foot as Marcelo Brozovic prodded the ball on following a backheel from Lukaku, who got the goal he deserved soon enough, too.

The game's standout performer span away from Sebastiano Luperto and sold Cordaz a dummy to leave a simple finish, although he then indicated an issue with 15 minutes remaining and was quickly substituted.

Martinez remained on the pitch to nod in the rebound when Cordaz saved from Ivan Perisic, Lukaku's replacement, and Hakimi had the final say.
 

What does it mean? Your move, Rossoneri

Milan are the only remaining unbeaten team in Europe's 'top five' leagues but will have to maintain their pace to keep clear of Inter on this evidence.

The Nerazzurri have won five in a row at home in Serie A for the first time since 2018 and look a match for any opponent with Martinez and Lukaku in top form.

Landmark Lukaku looks the part

This was Lukaku's 50th Serie A appearance and his tally of 35 goals in that time has only been bettered by five players in the three-point era.

It was the front man's work as Inter's battering ram that was most impressive here, however, finishing with just a single assist from his only key pass but winning both his duels and holding the ball up brilliantly to create the space for Martinez to have seven attempts.

Marrone endures torrid time

Marrone's own goal under pressure from Martinez epitomised a dreadful outing for the former Juventus defender.

He might have found his own net again early in the second half and was a liability throughout despite weighing in with four clearances, three interceptions and a tackle.

Key Opta Facts

- Inter have won eight Serie A games in a row for the first time since December 2008.
- Inter have scored at least 40 goals in the first 15 Serie A games played for the first time since 1950-51 (45 in that case).
- Crotone have conceded at least six goals in a Serie A match for the first time in their history.
- Martinez's treble is the first perfect hat-trick from an Inter player since Mauro Icardi in March 2017 (vs Atalanta).

What's next?

There is no easing back into league action in 2021 as Inter are playing again as soon as Wednesday, visiting Sampdoria. Crotone host Roma the same day.

Kieran Trippier's 10-week suspension for betting offences has been put on hold by FIFA following an appeal by Atletico Madrid.

The defender was issued a ban and a fine of £70,000 on December 23 after the Football Association found him guilty of four of seven alleged breaches of rule E8(1)(b).

The regulation states: "Where a participant provides to any other person any information relating to football which the participant has obtained by virtue of his or her position within the game and which is not publicly available at that time, the participant shall be in breach of this rule where any of that information is used by that other person for, or in relation to, betting."

Trippier, who denied the charges, was facing the prospect of missing 14 Atletico games up until February 28, a run that includes the first leg of their Champions League last-16 tie with Chelsea.

However, the 30-year-old England international will be free to play again while the appeal process continues.

A FIFA spokesperson confirmed on Sunday: "Following the appeal and, specifically, the request for provisional measures lodged by the club Atletico Madrid, the FIFA Appeal Committee has approved to stay the extension of the suspension against Kieran Trippier until the procedure is over before the FIFA Appeal Committee."

Trippier will miss Sunday's game between Atleti and Deportivo Alaves after being left out of the squad.

The former Tottenham man has played in 19 matches in all competitions this season for the LaLiga title-hopefuls, who are a point behind Real Madrid at the top of the table but with three games in hand.
