Porto and Sporting CP face a one-year ban from playing in Europe if they fail to pay outstanding debts by the end of next month.

UEFA on Friday revealed sanctions that have been issued to eight clubs for breaches of Financial Fair Play (FFP) regulations.

Primeira Liga leaders Porto and second-placed Sporting have been fined €300,000 and €250,000 respectively and will not play in the next UEFA club competition they qualify for in one of the next three seasons unless they can prove by January 31, 2022 they have settled "outstanding overdue amounts."

LaLiga side Real Betis have been hit with a €250,000 fine, while CSKA Sofia and CD Santa Clara were both ordered to pay €75,000 and Mons Calpe SC must fork out €15,000.

All of those clubs also face missing out on playing in Europe in either the 2022-23, 2023-24 or 2024-25 season if they qualify, but have not paid what they owe.

FC Astana and CFR 1907 Cluj were fined €150,000 and €200,000 respectively, but were not threatened with a ban.

The newly established First Chamber of the UEFA Club Financial Control Body (CFCB First Chamber) also found that AEK Athens did not comply with several club licensing and FFP rules.

The Greek club agreed to pay an unconditional financial contribution of €1.5million, while they will also withhold 10 per cent of UEFA prize money they make in the next UEFA club competition they qualify for.

Jurgen Klopp marvelled over a Thiago Alcantara "thunderbolt" but felt Liverpool were somewhat fortunate to beat Porto 2-0 in the Champions League.

Klopp rung the changes for Wednesday's clash at Anfield, with the Reds already through to the round of 16 as Group B winners.

Porto had their chances and were made to pay for their profligacy when Thiago fired home a sublime long-range first-time finish in the second half before Mohamed Salah clinically took his goal tally for the season to 17.

Thiago has endured a frustrating start to his Reds career, but he showed outstanding technique to get off the mark for the season and pulled the strings in the middle of the park alongside Champions League debutant Tyler Morton.

Klopp said of the Spain international's world-class finish: "We had bigger chances in the game than that. Incredible. 

"I see that in training, I know he has the technique to do it, but you don't always hit a thunderbolt like that. We needed some moments, some luck, they had big chances on the counter-attack."

Klopp gave key men a rest with qualification already assured and the Liverpool manager expects a stronger showing against Southampton in the Premier League this weekend.

He said: "We could have lost this tonight. We were lucky in moments, yes. We have moments when we're not cool to play against, true, but I didn't expect that tonight.

"I didn't expect a ruthless pressing machine, we grew into the game and that's what I am happy about. We have to play better against Southampton as they are a machine."

The German added: "We had lots to think about, who is injured. who hasn't played, who needs a rest.

"No one felt like they needed a rest as [playing] Saturday-Wednesday the boys are used to that, but it's about the games coming up, so we needed the boys in a rhythm. It all worked out. No injuries, all good."

Liverpool have won all five Champions League matches this season, while Porto remain second ahead of a decisive final group game at home to Atletico Madrid in a fortnight.

Milan, who face Liverpool at San Siro in their last group match, and Atleti are just a point behind Porto after the Serie A side beat the LaLiga champions 1-0.

Thiago Alcantara's sublime long-range strike set Liverpool on their way to a 2-0 Champions League win over Porto at Anfield.

The Reds had already qualified as Group B winners with two matches to spare, so teenager Tyler Morton made his Champions League debut as Jurgen Klopp rung the changes.

Liverpool maintained their perfect record in Europe this season despite being without key men, Thiago scoring his first goal of the season in style with a magnificent second-half finish.

Mohamed Salah added a second as Porto were made to pay for missed opportunities, leaving them facing a decisive final group match against Atletico Madrid in the battle for a place in the round of 16 along with Liverpool.

Porto should have had an early lead when Otavio somehow failed to hit the target with the goal gaping after Luis Diaz showed great pace to burst away and unselfishly set him up.

The Primeira Liga leaders had a let-off when goalkeeper Diogo Costa's poor attempted clearance struck Sadio Mane on the head and fell nicely for Salah, but the prolific forward could not apply the finish.

Porto lost captain Pepe to an injury before Mane had a goal disallowed for offside in a first half that saw Sergio Conceicao's side pose a threat without having a cutting edge.

Mateus Uribe almost capitalised on slack Reds defending when he spun sharply in the penalty area and drilled a right-foot shot narrowly wide as Porto continued to probe after the break.

Thiago made them pay for their profligacy seven minutes into second half, firing into the bottom-right corner from 25 yards out with a stunning first-time drive after Porto failed to clear an Alex Oxlade-Chamberlain free-kick.

Takumi Minamino had a goal ruled out for offside, but Salah doubled Liverpool's lead when he took a pass from Jordan Henderson and surged inside before finding the bottom-right corner with his left foot to take his tally for the season to 17.

Manchester City boss Pep Guardiola will be looking to seal top spot in Group A of the Champions League on Wednesday with a win against Paris Saint-Germain at the Etihad Stadium, having lost the reverse fixture 2-0 in the French capital in September.

Carlo Ancelotti and Real Madrid will also be seeking revenge as they visit Sheriff after the Moldovan outfit famously won 2-1 at the Santiago Bernabeu on matchday two.

After losing their first league game of the season at the weekend, Milan must find the first win of their European campaign if they are to keep their hopes of qualification alive when they travel to Atletico Madrid.

Stats Perform picks out the key Opta facts ahead of Wednesday's Champions League action.

Manchester City v Paris Saint-Germain: Messi aims to smite Guardiola again

Despite failing to find the net in Paris, only Bayern Munich (17) have scored more goals than Manchester City (15) in the Champions League this season. The Citizens are averaging 3.4 expected goals per game in the competition this term; since the start of 2013-14, this is the highest per-game average by a team in the group stage in a single Champions League campaign. 

PSG are winless in their past three away games in the Champions League (D2 L1), and could go without an away victory in the group stage of the competition in a single season for the first time since 2004-05. 

Lionel Messi, who fired home a brilliant second in the reverse game, has scored seven goals in seven Champions League appearances against City, the second-most by a player against an English club in the competition after his own haul of nine goals in six appearances against Arsenal.

7 - Lionel Messi has scored more UEFA Champions League goals against Man City (7) than any other player, while his seven goals against sides managed by Pep Guardiola (two vs Bayern Munich, five against Man City with him as manager) are also the most of any player. Haunting. pic.twitter.com/wPAYIZTx2R

Sheriff v Real Madrid: Can Benzema keep up his form?

Real Madrid have won both of their away games in the Champions League this season without conceding a goal (1-0 v Inter and 5-0 v Shakhtar Donetsk), while they last managed this in three consecutive away games in the competition between October 2014 and February 2015, during Carlo Ancelotti’s first spell in charge of the club.

After their famous win in Spain this season, Sheriff could become just the fourth team to win their first two meetings with Madrid in European competition, after Liverpool (1981, 2009), Galatasaray (2000, 2001) and Benfica (1962, 1965).

One rather big obstacle to stop that from happening is Karim Benzema, who has scored in each of his previous three Champions League appearances (four goals), and will be looking to do so in four in succession for the first time since 2016-17. His brace against Shakhtar last time out took him to 100 direct goal involvements in the Champions League (75 goals and 25 assists). 

Atletico Madrid v Milan: Must-win for the Rossoneri

Stefano Pioli's side need a win to keep their slim hopes of qualification for the knockout stages alive, having amassed just one point from their four games, but the numbers do not bode well for the Rossoneri. Atletico Madrid have a 100 per cent record against Milan in European competition, winning all three of their meetings, which have all been in the Champions League – 1-0 away and 4-1 at home in 2013-14, and 2-1 away from home this season. 

Joao Felix has been directly involved in four of Atletico's previous five goals at the Wanda Metropolitano in the Champions League, scoring three times himself and providing an assist for Antoine Griezmann against Liverpool in October.

Milan have only won one of their past 16 games against Spanish opponents in the Champions League (D6 L9), beating Barcelona 2-0 at home in the round of 16 in 2012-13. Indeed, they are winless in their previous six such games (D1 L5), suffering defeats in each of the most recent four. 

Liverpool v Porto: Salah still a threat despite no jeopardy for Reds

Liverpool may have already sewn up top spot in Group B, but they will want to keep up their impressive record against Porto. The Reds are unbeaten in their nine meetings in European competition (W6 D3), with five of those games coming during Jurgen Klopp's reign (W4 D1). 

Since the start of 2017-18 – Mohamed Salah's first season as a Liverpool player – the Egypt star has scored 30 goals in 47 Champions League appearances. Only four of these have been penalties, with Robert Lewandowski (33) being the only player to have netted more non-penalty goals in the competition than Salah (26) during this period.

Porto defender Pepe could make his 100th career start in the Champions League in this game. In doing so, he would become just the second Portuguese player in the history of the competition to start a century of games, after Cristiano Ronaldo.

Other fixtures:

Besiktas v Ajax

5 – Besiktas have lost all five of their meetings with Ajax across all European competitions – only against Dynamo Kyiv (six) have they suffered more defeats.

4 – Ajax are one of only four teams with a 100 per cent record through the opening four matchdays of the 2021-22 Champions League. The Amsterdam side will be looking to become only the second Dutch team to win their opening five games of a European Cup/Champions League campaign, after Feyenoord in 1971-72.

Inter v Shakhtar Donetsk

0 – The previous three meetings between Inter and Shakhtar Donetsk in the Champions League have finished goalless, with all three coming since the start of last season. There have been 66 shots recorded in these previous three games (43 by Inter and 23 by Shakhtar), without a goal being scored.

2 – Shakhtar Donetsk have only lost two of their past six away games against Italian sides in the Champions League (W2 D2), going unbeaten in the most recent two – 2-1 versus Atalanta in October 2019 and 0-0 v Inter in December 2020.

Club Brugge v Leipzig

1 – Club Brugge have only won one of their past 15 home games in the Champions League (D6 L8), with that lone victory coming against Zenit in December 2020 (3-0). This was the only game in this run in which the Belgian side managed to score more than one goal, netting just 10 across the 15 games in total.

0 – RB Leipzig are winless in their past six Champions League games, suffering five defeats in this run (D1). The Bundesliga outfit have also conceded more goals in the competition in 2021 than any other team, shipping 17 in six games this calendar year.

Sporting CP v Borussia Dortmund

3  – Only Salah (3.01), Lewandowski (4.77) and Sebastien Haller (5.51) have accumulated a higher xG tally (excluding penalties) in this season's Champions League than Sporting's Paulinho (2.96), who has scored with three of his six shots on target to date.

5  – Without Erling Haaland, who is already ruled out of this contest through injury, Dortmund have managed just five goals in four Champions League matches (1.25 on average), compared to 20 in 12 with him in the side (1.7) since his debut for the club in February 2020.

Jurgen Klopp was adamant that his Liverpool team will not step off the gas when they face Porto in the Champions League on Wednesday.

Liverpool host Porto in their fifth game of the Champions League campaign with top spot in Group B already secured.

The Reds have taken 12 points from 12 on offer so far, with a 2-0 win over Atletico Madrid last time out guaranteeing their position as group winners.

Porto were hammered 5-1 in the reverse fixture, though a win at Anfield could see them through should Atleti lose to Milan.

Klopp suggested he will look to rotate his side as the fixture list begins to become even more hectic, though insisted that does not mean Liverpool - who trashed Arsenal 4-0 on Saturday - will change their full-throttle approach.

"When you sign a contract for Liverpool as a manager or player you pretty much have to win all the games," he told a news conference.

"It means there's a lot of pressure on their shoulders. We don't have to win the game tomorrow but we want to win the game. I hope it gives us the freedom to play but have the desire to defend and all those kinds of things.

"In our Champions League history since I was here we always had to fight until the last second of the last game to get through the group, that's the only difference but actually it's not in my mind. I know it's a difference, but we try to win the game.

"We know that our opponent will be motivated in the highest level, for two reasons, because we won there in the other game in a way they didn't like and another is if they win they have a final against Atletico in the last match of the group, so that's what they want.

"It will be a difficult game for us, I really hope everybody at Anfield is at their best, we always show up to win the game. We never take this thing for granted, I hope nobody is doing that, we need to put a proper fight together, I'm pretty confident we can do that."

Liverpool also played in a Champions League dead rubber last season, with Klopp's decision to field a strong team backfiring when Diogo Jota sustained a serious injury.

"It's really easy to sit there and say leave him out, leave this player out," Klopp hit back when asked if he regretted that decision.

"It's very easy to sit in your chair, we have to line up a team to win the game and the Diogo situation was very unlucky and I hated it. Would I have done the same decision again? Yes.

"We need stability, we cannot play football games with one line up and then the next game change the team and then bring them back again, the players need rhythm, all these kinds of things.

"It's not fair that you bring it up this old story that a player got injured. These things happen in football and hopefully nothing happens tomorrow."

Jordan Henderson and Andrew Robertson are, according to Klopp, fit after returning from injuries, though he is unsure if either will play a part against Porto, who have never beaten Liverpool in nine competitive meetings.

One player set to feature is Takumi Minamino, who scored less than a minute after coming on from the bench against Arsenal.

Klopp said: "He played for Japan in the last few games because he's in good shape, he's in exceptional shape, we knew that.

"That's why it's important for us. He's pretty much our first option for changing five positions, that says a lot, because he can play all the different positions and when he came on it was a wonderful moment, 40 seconds on the pitch and scoring a goal.

"You can see the confidence now and how good a player he is. He will get his minutes, definitely."

Luis Diaz's agent says it is "normal" the Porto winger is attracting interest from Europe's heavyweights, amid links to Liverpool and Chelsea.

Since making the switch from Colombian side Junior to Porto in July 2019, Diaz has scored 21 goals, provided nine assists and created 59 chances in Portugal's Primeira Liga.

This season alone, he has nine goals in 11 top-flight appearances to stand top of the scoring charts in Portugal's highest tier.

The 24-year-old has a reported €80million release clause in his contract, with Premier League sides Liverpool and Chelsea reported to be weighing up a move for the Colombia international.

He has also caught the eye in the Champions League this term, scoring against Atletico Madrid and Milan, and will come up against Liverpool in Europe's premier competition next week.

For his representative, Carlos Van Strahalen, such attention is to be expected given his impressive form.

Speaking to Bola Branca, Van Strahalen said: "It's normal. If a player plays well, if he starts to stand out, if the majority considers him the best player in the Portuguese league, if he's the top scorer and is making a high-level Champions League, that interest is normal.

"Can he leave Porto? I don't know."

Jurgen Klopp insisted Liverpool will take their two remaining Champions League group games seriously after they secured a place in the knockout stages in record time.

The Reds made it four wins from four in the group stages of Europe's elite competition for the first time in their history as they beat Atletico Madrid 2-0 at Anfield on Wednesday.

That result means they are guaranteed to progress to the next round as group winners regardless of the outcome of upcoming fixtures against Porto and Milan, but Klopp has suggested he will still take both very seriously.

"You earn a lot of money if you win Champions League games - not me personally, it's just for the club it's important. That's what we will do," Klopp said during the post-game news conference.

"Of course, the first target was to get through this group and getting through the group with 12 points after four matches is absolutely insane, to be honest. 

"But we did it and now there are two more games to go. One is against Porto and we are Liverpool in a home game, what can we do? Let them play or whatever? 

"And then, going to Milan, I've never been there. It's a historical one, so we will show up there as well. That's the situation. 

"But, of course, when I saw the group I didn't expect that we would be through after four games, but the boys did it and really well deserved."

Liverpool's task was made all the easier when Atletico's Felipe was sent off for a cynical swipe at Sadio Mane during the first half at Anfield.

But Klopp felt he had to substitute the Senegalese himself at the break in order to avoid him receiving a second yellow card.

Explaining the decision, he said: "I really hated the moment when I had to take off Sadio because Sadio played an incredible game. You could see now everybody wants it [the red card]. 

"My worry was any kind of challenge in the air, where you never know exactly what happens there with the arm, one of them goes down and makes three times a roll over then Sadio's off and that would have been the wrong thing. I didn't like it but, in the end, we had to do it." 

Stefano Pioli is eager to take positives from Milan's second-half performance against Porto ahead of this weekend's huge Derby della Madonnina clash with Inter.

Milan ended a club-record run of five successive defeats in the Champions League with a 1-1 draw against Primeira Liga leaders Porto at San Siro on Wednesday.

That solitary Group B point after four matches all but ends the Rossoneri's hopes of qualifying for the last 16, though, as they must win both remaining games and hope other results go their way.

Pioli's side fell behind to a Luis Diaz strike with just five minutes and two seconds on the clock – the second-fastest goal they have conceded at home in the Champions League.

Porto looked a lot sharper and should have doubled their lead when Evanilson headed against the crossbar, but Milan earned a point through Chancel Mbemba's comical own goal.

Despite remaining bottom of the group, Pioli is remaining upbeat with his side flying high in Serie A ahead of the showdown with rivals and reigning champions Inter.

"The signs are positive for us, even if the team is disappointed," he told Amazon Prime. "We wanted to find our first victory in the Champions League. 

"It is true that their pressure was strong in the first half. In the second half we did better. We moved better and their intensity in the pressure dropped.

"It is clear that conceding a goal like we did influenced our way of playing. I can't say much about the second half, especially in terms of our aggression. 

"Porto are a strong team, who last year eliminated Juventus. The level in this competition is very high. To win in the Champions League you have to deserve it. 

"The next game will be just as difficult. Inter deservedly won the championship and remain favourites to retain the title. 

"We will have to play a high level match, but we have the opportunity to do well."

Milan have won just one of their past 11 Champions League games, whereas Porto have now lost just one in nine in the group stage.

The Portuguese side had a three-day gap between their 4-1 win against Boavista and the game at San Siro, compared to a couple of days off for Milan following their win at Roma.

That was also the case prior to last month's reverse fixture, which Porto won 1-0.

"They played a day before us twice in a row," Pioli said. "If you have seven or eight days to recover it doesn't make a difference.

"But if you have three instead of four in a period where you play seven times in 21 days, it can make a difference."

Olivier Giroud was selected ahead of Zlatan Ibrahimovic up top for Milan but could not find a way through as his scoreless run in the competition stretched to 326 minutes.

At 35 years, Giroud was the oldest member of Milan's line-up and feels a lack of experience has perhaps cost his side in Europe this term.

"We're a young team but I don't want to make excuses," he told Canal+. "We also needed a little more luck. We have played some good matches in the group.

"It's tough against teams who are used to Champions League football like Porto or Atletico. Experience is important.

"Now we've got the derby with Inter and we will look to come back with the same energy and desire for that game."

Milan are on the brink of an early Champions League exit after being held to a 1-1 draw at home to Porto.

Luis Diaz scored the winning goal when these sides met two weeks ago and fired Porto into an early lead in this latest Group B encounter at San Siro.

Evanilson missed a glorious chance to double the Primeira Liga leaders' advantage and that proved costly when Chancel Mbemba comically found the back of his own net.

But Milan could not find a winner and now require Liverpool to avoid defeat against Atletico Madrid later on Wednesday if they are to avoid elimination with two games to play.

Marko Grujic was a late replacement for the injured Mateus Uribe's in Porto's line-up and the midfielder played a big part in the visitors' opener, dispossessing Ismael Bennacer and playing in Diaz, who calmly slid the ball past Ciprian Tatarusanu.

At five minutes and two seconds, that was the second-fastest goal Milan had conceded at home in the competition – after Jari Litmanen for Ajax in 1994 – and the hosts could only muster a saved Olivier Giroud attempt in response before half-time.

Porto went close to moving further in front when Pepe flicked on a free-kick and Evanilson clipped the top of the crossbar with a header from close range.

Six minutes after that squandered opportunity, Giroud's parried shot was turned back across the face of goal by substitute Pierre Kalulu and poked over the line by Porto defender Mbemba under no real pressure.

Zlatan Ibrahimovic was introduced from the bench and thought he had snatched a late winner, only for the offside flag to quickly go up as Stefano Pioli's men failed to find the winning goal they desperately required.

Atletico Madrid are hoping to recover from losing to Liverpool on matchday three with a repeat of their Anfield heroics last March.

Paris Saint-Germain and Manchester City will look to take bigger steps towards the last 16, while Real Madrid will go in search of another big win against Shakhtar Donetsk.

Inter can put themselves in a good position to progress, too, although city rivals Milan have got much more of a fight on their hands.

Here are some of the key Opta facts for Wednesday's Champions League matches...

Liverpool v Atletico Madrid: Can Suarez improve rotten recent record?

Atletico were winners at Anfield on their last visit as they claimed a 3-2 victory in the last-16 second leg in March 2020. Indeed, Liverpool have only twice beaten Spanish teams at home in 13 attempts in the European Cup and Champions League.

That said, the Marcos Llorente-inspired game last year was one of only two out of 22 at home that Jurgen Klopp has lost in this competition as Reds manager, while Diego Simeone is chasing what would only be the second instance of a third successive away win in the tournament with Atleti.

Luis Suarez will hope to haunt his old side, although recent history is against him: he's only scored one for Atleti in nine Champions League games, and none from open play. Mohamed Salah, meanwhile, needs one more goal to equal Steven Gerrard as Liverpool's top scorer in the competition at Anfield (14).

Manchester City v Club Brugge: Bad omens for Belgian champions

City's 5-1 triumph in Bruges on matchday three took their tally to six wins in seven European games against Belgian opposition, while Brugge are now without a victory over English teams in 13 attempts dating back to February 1995.

Since Pep Guardiola took charge, City have won 80 per cent (20 out of 25) of home Champions League matches, which is the best record for a coach at a single club in the competition among those to take charge of 20 or more. A first win on English soil for Brugge looks unlikely.

Might this be a chance for Raheem Sterling to impress? The England forward has been directly involved in 24 goals in 27 home Champions League games for City, a tally surpassed only by Sergio Aguero (27).

RB Leipzig v Paris Saint-Germain: Nkunku could outshine Messi

PSG have only lost one of their past nine away games in the group stage, but that defeat was against RB Leipzig last season. It was the only time in the previous seven meetings with French sides that Leipzig emerged victorious.

He might be enduring a difficult time in Ligue 1, but Lionel Messi has managed three goals in three games in Europe for PSG. His double in the reverse fixture was his 34th in the competition, something only Cristiano Ronaldo (37) can better.

However, perhaps the most in-form player in 2021-22 is Leipzig's Christopher Nkunku, who has been involved in the most open-play sequences ending in a goal (six) among Champions League midfielders this season. And he has four goals of his own from the first three matches.

Real Madrid v Shakhtar Donetsk: Another big win on the cards with Benzema

Madrid's 5-0 win over Shakhtar on matchday three means the past five meetings between these teams have seen an average of 4.6 goals scored per game. In fact, Los Blancos have scored 15 times in five Champions League matches against Shakhtar: that average of three per game is their best figure against a side they have faced on at least five occasions, apart from Galatasaray (3.4 per game).

Shakhtar are one of just three sides yet to score in this season's group stage, but with Madrid having lost three of their previous eight home games in the competition, this could be a good opportunity.

They will need to stop Karim Benzema and Vinicius Junior, though: they are the two players with the most involvements in shot-ending sequences in 2021-22 (31 and 34, respectively). Plus, Benzema is on a run of 10 goals in 10 home games in the competition.

Sheriff v Inter: Nothing shot-shy about Inzaghi's men

Inter ended Sheriff's 11-game unbeaten run in Europe last time out and will now look to secure consecutive Champions League victories for the first time since October 2018.

The Nerazzurri have lost just once in their previous five Champions League away matches, but Sheriff are unbeaten in their most recent five European games on home soil, excluding qualifiers. They've also won the past two.

Inter certainly have the variety to break down Sheriff's stubborn defence. Each of their previous 17 away goals in the competition have come from open play, while their 29 shots in the meeting on matchday three were the most by an Italian side in a Champions League game since at least 2003-04.

Other fixtures:

Borussia Dortmund v Ajax

45 – Ajax's 4-0 win over Dortmund last time out was the biggest victory by a Dutch side over a German team in Europe since November 1976, when Feyenoord defeated Kaiserslautern 5-0 in the UEFA Cup.

8 – Sebastien Haller has been directly involved in more Champions League goals this season than any other player (eight – six goals, two assists). Among debutants in the competition since 2003-04, this is the highest such figure over a player's first four appearances and one more than Erling Haaland managed.

Milan v Porto

3 – Milan are one of just four sides this season to have lost all three group games. They are on a five-game losing run in the competition, the worst such streak in their history.

1 – Since scoring four for Chelsea against Sevilla in December 2020, Olivier Giroud has scored only once in 250 minutes of play in the Champions League.

Sporting CP v Besiktas

5 – Paulinho has been directly involved in three of Sporting's five goals (two scored, one assisted) in this season's Champions League. Their last player to manage more goals and assists combined in a single season was Nani in 2014-15 (six).

10 – Michy Batshuayi has attempted 10 shots for Besiktas in the Champions League in 2021-22 without scoring. Over the first three matchdays, only Inter's Lautaro Martinez (12) had more shots without finding the net.

Davide Calabria fired a warning to Milan as he declared Wednesday's clash with Porto to be their last chance of staying in the Champions League.

The Rossoneri are bottom of Group B, having lost all three of their matches against Liverpool, Atletico Madrid and Porto, and are on a five-game losing streak overall in the competition – the worst such run in their history.

Should they lose to Sergio Conceicao's side at San Siro and Atletico beat Liverpool at Anfield, Milan will be unable to finish higher than fourth in the group, meaning their European campaign would be over for 2021-22.

While their domestic form has been strong – they have won 10 of 11 Serie A matches this season, something only three teams have achieved before – Milan were deeply unconvincing in the reverse match against Porto, registering only four shots, their lowest such figure in a Champions League game in almost eight years.

Calabria feels Milan deserve to have at least some points from the first three matchdays but accepts a win is now essential to their chances of going through.

"We have an outlook prepared; it's our last chance to stay in the Champions League," the defender said on Tuesday. "We believe in ourselves and we have the quality to put in a great performance right from kick-off and stay in the competition.

"Certain moments have led to the current standings. We don't deserve it but I am convinced that we have the potential to do better and take points, starting from tomorrow.

"The Champions League is a competition that comes down to the finer details and some of the details have gone against us. It's a shame because we deserve more but there's not much to say. We've been decent in the group until now, except for the game in Portugal."

Milan come into the match buoyed by Sunday's 2-1 league win at Roma, a result that ended Jose Mourinho's 43-game unbeaten home run in Serie A.

The match was not without controversy, though. Referee Fabio Maresca was criticised for his performance, as was VAR, with Mourinho walking away from a post-match interview with DAZN after claiming he feared a touchline ban if he spoke about the officials.

Milan boss Stefano Pioli insisted he and his team cannot become distracted by a growing debate over the standard of officiating in Italy.

"I believe one thing: we beat Roma because we were the better team and lost against Porto because they were better than us," Pioli said. "I can't control anything else.

"We're just going to keep our focus on what we are doing. We analysed the performance with the players and we know what we did well. We can't waste our energy on external factors.

"Now, we are thinking about the Champions League because we feel like we deserve more than zero points in the table and we have this game to confirm that – against a really tough side."

Nuno Espirito Santo's future as Tottenham manager is in doubt after a slow start.

The Portuguese only took over in June but his side are eighth in the Premier League with five losses already.

Spurs were humbled 3-0 at home by under-pressure Manchester United on Saturday.

Supporters made their feelings known at full-time as boos rung out around Tottenham Hotspur Stadium.

TOP STORY – SPURS READY TO REPLACE NUNO

Tuttomercato claims that Tottenham are working on a deal to have ex-Inter boss Antonio Conte replace Nuno Espirito Santo as manager.

Football Insider also reports that Spurs will sack Nuno this week, with Ryan Mason to be installed as their interim boss again.

Luis Diaz's second-half finish propelled Porto to their first win in the Champions League this season as they beat Milan 1-0 to leave the Italians staring at an early exit.

Sergio Conceicao's side were demolished 5-1 by Liverpool in their previous European outing, while Stefano Pioli's men suffered last-minute heartbreak against Atletico Madrid to leave both sides winless from their first two Group B games.

Diaz looked to seize the early initiative but was denied by the woodwork after just four minutes, with Medhi Taremi then spurning a series of chances.

However, Diaz managed to break the deadlock at Estadio do Dragao after the interval to condemn Milan to consecutive European away defeats for the first time since April 2012.

Diaz almost offered the hosts the perfect start, the Colombia international drilling a low drive against the left post before Taremi curled narrowly wide.

Olivier Giroud then misdirected a header after Rafael Leao's cross created Milan's first presentable opportunity, with Taremi missing a headed chance of his own before poking wide as Porto failed to make their first-half dominance pay.

Taremi remained persistent in his pursuit of the opener after the interval, dragging a left-footed strike narrowly off target after capitalising on Fikayo Tomori's mistake.

Tomori made amends with a last-ditch block to deny Otavio before Mateus Uribe arrowed just the wrong side of the left-hand post, but Porto did not have to wait much longer for their deserved opener.

The visitors felt Ismael Bennacer was fouled by Taremi in the build-up but referee Felix Brych disagreed as Diaz fired into the bottom-right corner after 65 minutes, with Pepe angling a rare left-footed effort wide three minutes later.

Pioli's team never looked like finding a late equaliser as Porto recorded their seventh clean sheet in their last eight group-stage matches in the competition.
