Sergio Conceicao fears Chelsea's shock loss to West Brom could work against Porto heading into the first leg of their Champions League quarter-final tie.

Chelsea had not lost under Thomas Tuchel before a stunning 5-2 home reverse on Saturday, a result that led to the Blues dropping out of the Premier League's top four.

Defender Thiago Silva was sent off shortly after his side had taken the lead against relegation-threatened opponents, with his dismissal leading to a dramatic collapse that Tuchel admitted in the aftermath was "tough to digest".

Porto, therefore, are wary of a possible backlash from that result in Seville, the venue for both games between the teams due to the travel restrictions in place during the coronavirus pandemic.

"You know that Thiago Silva was sent off in the first half and that the game had a different course," said Conceicao, whose side will be listed as the home team on Wednesday.

"Chelsea until this last game had been extremely competent, they have not lost a game in the Champions League. They are a competent team, and when these defeats happen, it serves as a warning.

"If you want my opinion, I would prefer that they won the last game. These situations make the siren sound and make everyone more alert, more awake to danger, and I honestly don't like these defeats very much."

Rather than read too much into the West Brom game, Conceicao highlighted how Chelsea had impressively overcome Atletico Madrid in the last 16, winning both legs without conceding a goal.

He also referenced his opposite number's penchant for tinkering with tactics to suit each match situation, something he says Tuchel also did during his time in charge at Paris Saint-Germain.

"In the analysis of Chelsea, practically that last game wasn't considered," the former Portugal international said.

"There were other games that they played before that, namely those in the Champions League against Atletico Madrid, but this one [against West Brom] did not enter [our analysis].

"Tuchel is a coach who is capable of changing even if he wins, while in France he did the same at PSG. Play with two men behind the striker or play with two men in front, as in the first round with Atletico. It is up to us to analyse that dynamic.

"I saw the last game they played, but we did not present images to the players of that game."

Porto made it through to the last eight at the expense of Juventus, but veteran centre-back Pepe made clear the players will not dwell on their Turin heroics and instead focus on the task in hand - getting past Chelsea.

"The Juventus match is already in the past. This is the important one now. We must show a lot of passion and humility and work as a team," said the defender, a three-time Champions League winner during his time at Real Madrid.

"We have prepared well. Nothing is certain in football, but I hope we will be the team that our fans expect. We respect Chelsea. It will be difficult, but we want to win this tie."

Thomas Tuchel confirmed Antonio Rudiger and Kepa Arrizabalaga were involved in an altercation in the wake of Saturday's shocking 5-2 defeat to West Brom, a game that Chelsea's head coach still cannot get his head around.

Chelsea found themselves on the end of a humiliating loss to the Premier League's second-bottom team, conceding five goals in a home league game for the first time since October 2011.

Similarly, West Brom netted five times on the road for the first time in over nine years.

Thiago Silva's sending off when Chelsea were 1-0 up was deemed to be the turning point, with Matheus Pereira netting a brace just prior the break, before Callum Robinson repeated that feat in the second period. Mbaye Diagne got the other Baggies goal, with Mason Mount's strike a mere consolation.

If the defeat was not bad enough, reports emerged the next day claiming Rudiger and Kepa had been involved in a bust-up at training.

While Chelsea did not comment on the matter publicly, Tuchel was open about the situation in Tuesday's news conference as he addressed the media ahead of the club's Champions League quarter-final first leg against Porto.

"It was not [serious]. It was an incident in training and got heated between Toni and Kepa," Tuchel said. "We calmed the situation down immediately. I don't want to play things down artificially, we do not want to accept [such incidents] but they can happen because everyone is competitive in training matches.

"The reaction to it, Toni and Kepa, was amazing. They showed how much respect they have for each other. They cleared the air and there was nothing left one day after.

"We spoke about the issue and then it was solved. This is the main part. It will stay with us, it wasn't awkward. They solved it straight after training in an honest and humble way and it showed me they have good character."

But although he initially played down the incident, Tuchel backtracked and emphasised the gravity of what occurred.

"It was serious," he continued. "Sometimes you have little situations when you look away and let them sort things out. We needed to interfere in this situation, so it was serious. How the guys handled the situation was impressive and showed character, but the situation was serious.

"That it got out [leaked]...I get used to it in modern times. There are too many channels and ways that information can get out. I heard even that some of my debrief from the match got out there too. Ok, it's not nice but I am not going to focus on who is the leak or whatever. I don't want to lose my trust in the group so I will accept it."

Regarding a punishment, Tuchel confirmed Rudiger will play on Wednesday and added: "No, no punishment so far because of the way they dealt with it. The reaction was immediate, they made it clear for everybody what happened. Toni sorted out it directly, which was necessary. It was a strong and brave thing to do and the right thing to do."

Tuchel quickly used the scrap to turn attention back to Chelsea's misfortune against West Brom, adamant that the statistics of the game suggested they ordinarily would have won.

"It's very natural there is a reaction to a result and game like this, so it is necessary to adapt," the German said. "It is a strong part of sports at this level that the guys hate to lose. So, if we suffer a big loss in a weird game, it's normal there are reactions.

"You have to swallow it and accept we lost the game. Then it's important that we are reliable in analysing the game. We can't only do meetings depending on the result. We can be critical after wins and we can point out things we like even though we lost 5-2.

"Part of this game's story is we won all the statistics against West Brom, all of them, with 10 men and 11 men, all statistics that matter to win games. Even expected goals [xG], we won the bypassed defenders, we won touches in the box, we won shots on targets – we won everything.

"If we played the same game again, I would bet a lot of money that we win 99 times out of 100."

And Tuchel has a point – in terms of xG, Chelsea edged West Brom 2.1 to 1.6, meaning the visitors were incredibly clinical with their chance-taking.

Nevertheless, West Brom's xG value was comfortably the highest registered by any team against Chelsea since Tuchel was appointed in January.

With a man advantage, West Brom certainly capitalised on the extra time and space in the final third.

Both legs of Chelsea's Champions League quarter-final with Porto will be staged at Sevilla's Ramon Sanchez Pizjuan stadium.

UEFA announced the move on Tuesday, with the coronavirus pandemic placing restrictions on travel to and from certain countries.

The governing body said in a statement: "UEFA is able to officially confirm that the UEFA Champions League quarter-final first and second leg matches involving FC Porto and Chelsea FC, will now both be played at the Estadio Ramon Sanchez Pizjuan in Seville. The dates of the matches (7 April and 13 April 2021) and the kick-off times (21:00CET) will remain the same.

"UEFA would like to thank FC Porto and Chelsea FC for their support and close cooperation, as well as the Portuguese Football Federation, the Football Association, the Royal Spanish Football Federation and Sevilla FC for their assistance and agreeing to stage the matches."

The Blues played the first leg of their last-16 tie with Atletico Madrid in Romania, with travellers from the UK banned from entering Spain.

Thomas Tuchel warned his side against complacency for the Porto tie even before losing the benefit of a game on home soil, with Chelsea having been installed as firm favourites to reach the semi-finals.

Chelsea have won five of their eight prior meetings with Porto, including all four at Stamford Bridge, their best 100 per cent home win rate against any opponent in European competition.

But given the Portuguese side eliminated Cristiano Ronaldo and Juventus in the last round, head coach Tuchel is not taking Chelsea's progress for granted.

"Clearly, many people will maybe now make us the favourites against Porto," he said. "That will not help us. You can ask in Turin about the opinion on this, if it helps you to be favourites. It does not help you.

"But we are self-confident. Being self-confident is strongly connected with our performances. We are confident that we face a strong opponent that we face with all the respect.

"Now we are in the quarter-final, we think about how to win it. The only thing we focus on is to reach the semi-finals. We are self-confident enough that we see our chances."

Thomas Tuchel pointed to Porto's defeat of Juventus as evidence Chelsea cannot get carried away following their Champions League draw.

The Blues, who knocked out Atletico Madrid this week, will face Porto in the quarter-finals of the competition in a seemingly kind draw.

Chelsea have won five of their eight prior meetings with Porto, including all four at Stamford Bridge, their best 100 per cent home win rate against any opponent in European competition.

But given the Portuguese side eliminated Cristiano Ronaldo and Juve in the last 16, head coach Tuchel is not taking Chelsea's progress for granted.

"Clearly, many people will maybe now make us the favourites against Porto," he told a news conference. "That will not help us.

"You can ask in Turin about the opinion on this, if it helps you to be favourites. It does not help you.

"But we are self-confident. Being self-confident is strongly connected with our performances. We are confident that we face a strong opponent that we face with all the respect.

"Now we are in the quarter-final, we think about how to win it. The only thing we focus on is to reach the semi-finals. We are self-confident enough that we see our chances."

Tuchel was speaking ahead of Sunday's FA Cup tie against Sheffield United at Stamford Bridge, another favourable last-eight fixture.

Chelsea have come out on top in four of the teams' five previous clashes in the competition, while they are on a four-match winning run at home in the FA Cup.

Tuchel is similarly wary for this match, though, even if he acknowledges the prospect of a potential double with the Champions League will now be recognised.

Asked about that possibility, he replied: "It's a bit like if you asked me on my first day if we can be unbeaten after 13 games and do 11 clean sheets. I don't know. Maybe yes, maybe no.

"I can only tell you: is it possible to win against Sheffield on Sunday? Yes, it is possible. Is it easy? No. If you want to win, if you want to be in Wembley, you need to win this game. There is no other approach.

"Is it possible to win the FA Cup? Yes, for sure. Is it possible to win the Champions League when you arrive in the quarter-final? Yes, for all eight teams, it's possible.

"And from there on, admit it and put it aside, because you just lose focus. The focus is performance, intensity, attitude, mentality against Sheffield, and nothing else.

"Then first leg against Porto, then second leg, and be ready every minute of the game because this is football. Everything can happen.

"I'm pretty sure, 100 per cent sure, Sheffield will arrive to beat us, and Porto will arrive to beat us. These are the challenges. We will see where the limit is."

Title-holders Bayern Munich face a repeat of last season's final against Paris Saint-Germain in the quarter-finals of the 2020-21 edition.

While the Parisians will be sure to test their title defence, Bayern have won each of their previous four knockout encounters with French opposition in the Champions League, including August's final.

Real Madrid and Liverpool will face each other in a two-legged knockout tie for only the second time – the first saw the Reds inflict Los Blancos' biggest-ever aggregate defeat (5-0) in 2008-09.

Similarly, Jurgen Klopp has faced Madrid more often than any other opponent in the Champions League (seven), with only Ottmar Hitzfeld (12) managing against them more often in the competition.

Manchester City are to go up against Borussia Dortmund, having only lost one of their 12 home games against German teams in the Champions League, that solitary defeat coming to Pep Guardiola's Bayern in 2013.

The omens are similarly good for Chelsea, who have won each of their four previous home games against Porto, their best 100 per cent winning ratio at Stamford Bridge against any side across all European competitions.

Quarter-final draw:

Manchester City v Borussia Dortmund

Porto v Chelsea

Bayern Munich v Paris Saint-Germain

Real Madrid v Liverpool

Semi-final draw:

Winner of QF 3 v Winner of QF 1

Winner of QF4 v Winner of QF 2

Revenge for last season's final defeat will be on the minds of Paris Saint-Germain after being drawn against Bayern Munich in the Champions League quarter-finals.

Bayern lifted the trophy in August last year when they defeated PSG 1-0 thanks to a goal by Kingsley Coman, a youth product of the Parisian side.

It was PSG's first ever appearance in the Champions League final and therefore closest they have come to European glory since the 2011 takeover by Qatari Sports Investments (QSI), who pledged to build a club capable of winning the competition when they secured ownership.

After a run of three successive eliminations at the last-16 stage, this is the second year in a row that PSG have reached the quarter-finals, having eliminated Barcelona in comfortable fashion this month.

But to get any further they will have to avenge their final defeat of last year, after Bayern dealt with Lazio in similarly resounding fashion.

Liverpool may also be eager for a slice of payback when they go up against Real Madrid next, with Zinedine Zidane's men beating them in the 2018 final – though the Reds did go all the way the following year.

Jurgen Klopp's men have found themselves in a spot of bother domestically in recent months, having lost eight times in the Premier League since the turn of the year, but against RB Leipzig in the last-16 they were fairly comfortable as they won both legs 2-0.

Madrid saw off Atalanta 4-2 on aggregate in the last round and are unbeaten in nine across all competitions.

If he guides them to another European title this term, Zidane will become the first coach to win the trophy four times.

Manchester City and Borussia Dortmund will contest a tie that's sure to excite the neutrals, with Pep Guardiola's runaway Premier League leaders set to contend with Erling Haaland.

The Norwegian striker's father, Alf-Inge, captained City in 2000-01 and has been linked with them himself, as well as their rivals Manchester United.

The third English club hoping to reach the semi-finals is Chelsea and they are likely to be the happiest of bunch having been paired with Porto.

Nevertheless, Sergio Conceicao's men eliminated Juventus in the last round and will be relishing another opportunity as the underdog.

Revenge for last season's final defeat will be on the minds of Paris Saint-Germain after being drawn against Bayern Munich in the Champions League quarter-finals.

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."

Juventus winger Federico Chiesa insists the Bianconeri did not deserve to be eliminated from the Champions League by Porto, adamant they did enough to progress.

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, but a brace from Chiesa early in the second half initially spared the hosts.

In doing so, Chiesa became the first Italian to score twice in a Champions League knockout game for Juve since Filippo Inzaghi in April 1999.

And it 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 a Sergio 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, and Chiesa was left exasperated.

"I don't take any positives from this," he told Sky Sport Italia. "I wanted us to go through and we have great regret because after the first half, we did enough to deserve to qualify – from the many chances to Juan Cuadrado's shot hitting the crossbar.

"When you don't qualify, you have to analyse what happened, but it feels to me that we had a different mentality in the second half and we deserved to qualify.

"We wanted to be in the quarter-finals, but we're not. Now we have to focus on Serie A and the Coppa Italia."

The elimination leaves Juve's season with a rather bleak outlook considering there are 10 points adrift of leaders Inter in the Serie A table. Even if they win their game in hand, they will still have a significant gap to claw back.

Matthijs de Ligt acknowledged getting dumped out of the competition is difficult to digest, particularly after playing over an hour of the 120 minutes on Tuesday with a numerical advantage.

"This is tough, yes, really tough," he added. "When you're playing against 10 men for almost the whole match, it's always difficult to take when you then go out in this manner.

"I don't think we started poorly. Porto went ahead and then we started playing, so that was too late. We did well in the second half with our pace, creating chances, getting two goals, but ultimately the ball didn't go in the net [enough].

"Of course, this changes our season because we wanted to be in the Champions League and now we are out in March. This is very difficult for us."

Porto head coach Sergio Conceicao was not asked any questions by the media in his post-match news conference, despite the club's stunning triumph against Juventus in the Champions League.

Juventus beat 10-man Porto 3-2 after extra time on Tuesday, but the Portuguese powerhouse still advanced to the quarter-finals 4-4 on away goals.

Federico Chiesa scored a second-half brace for Juve and Adrien Rabiot headed home after Sergio Oliveira's second goal to set up a grandstand finish, but the Italian giants fell short at home in Turin.

It marked the first time Porto progressed from a Champions League knockout tie after winning the first leg since 2003-04.

But Conceicao left his post-match news conference without making any comments – no Portuguese journalists were on the Zoom call to discuss the memorable victory.

However, Conceicao did speak to UEFA about Porto's success after Mehdi Taremi was sent off for two bookable offences nine minutes into the second half.

"These games are marked in the history of the club. The players dignified the fans with the passion they have," Conceicao told UEFA.com.

"The players managed to get the true essence and true DNA of FC Porto. Their incredible determination and spirit of sacrifice touched me.

"I have a group of brave players who interpreted what we wanted in the best way, against a great team with players of a very high level. We suffered but also created difficulties for Juventus. We were a real team.

"Congratulations to the players, they did a fantastic job. After Taremi's expulsion, we showed the FC Porto DNA. We never stopped believing – this is the true DNA of FC Porto."

Porto's starting XI against Juventus was the second oldest in their Champions League history (29 years and 16 days), behind only their match with Barcelona in March 2000 (29 years and 86 days).

Andrea Pirlo said he has not received reassurances over his Juventus future, rather confirmation from the president that the "project has just started" in Turin following the club's Champions League last-16 exit at the hands of Porto.

Juve crashed out of the Champions League in the round-of-16 stage for the second consecutive season – the Serie A titleholders bowing out 4-4 on away goals despite beating 10-man Porto 3-2 after extra time on Tuesday.

Federico Chiesa scored a second-half brace for Juve and Adrien Rabiot headed home after Sergio Oliveira's second goal to set up a grandstand finish, but the Italian giants fell short.

For the first time in the European Cup/Champions League, Juventus have been eliminated in the last 16 for two consecutive seasons as pressure mounts on first-year head coach Andrea Pirlo.

Pirlo, who replaced Maurizio Sarri at the start of the season, also finds his Juve side third in Serie A and 10 points adrift of leaders Inter.

Asked about his future and whether he had spoken to Juve president Andrea Agnelli, Pirlo told reporters: "The president didn't reassure me. He just confirmed that this project has just started.

"I'm absolutely calm about the future, I'm sure we will go forward together. We just started last summer. All players that joined Juventus last summer have showed that they have what you need to play at this level. So I'm sure we can do better in the next future."

Juventus failed to progress from the knockout stage of the Champions League after extra time for the first time since 2016.

"I spoke with the president after the game and we spoke about the game and what we need to do to improve in the future," Pirlo added. "We started well the game tonight. We had an occasion to score with [Alvaro] Morata but we missed it and then we conceded the first goal.

"After their goal we suffered, we were too long and also psychologically we were not in the game thinking that was too hard to come back. In the second half instead we played with a different approach and we were able to overturn the result. We were unlucky in some episodes and in the end we made another mistake that costed us the qualification."

Cristiano Ronaldo fired a blank as Juventus bowed out on Tuesday – a result that immediately cast doubt over the 36-year-old's future with the Bianconeri.

Juve have not advanced past the quarter-finals since five-time Ballon d'Or winner Ronaldo arrived from Real Madrid in 2018, having finished runners-up in two of the previous four seasons prior to his blockbuster signing.

Aside from his assist for Chiesa's first goal, Ronaldo was largely subdued against Porto, but Pirlo defended the five-time Champions League winner.

"When Ronaldo plays in Champions League usually is like your team begin the game one goal ahead of your opponent. But it can happen even to an extraordinary player like him not to be able to score," Pirlo said.

"Federico scored twice and played a great much. Also a champion like him [Cristiano] can have a bad game. He fought a lot tonight but unfortunately he didn't lead us to go through the next stage this time."

Juventus only had themselves to blame as they crashed out of the Champions League on away goals to 10-man Porto, according to head coach Andrea Pirlo.

A thrilling tie finished 4-4 on aggregate after extra time in Turin, but a 115th-minute free-kick from Sergio Oliveira – who opened the scoring with a first-half penalty – meant Porto progressed despite losing 3-2 on the night.

The brilliant Federico Chiesa scored a second-half brace for Juve and Adrien Rabiot headed home after Oliveira's second to set up a grandstand finish.

But it was not enough, as Cristiano Ronaldo again drew a blank when faced with long-time international team-mate Pepe at the heart of a dogged Porto defence.

Pirlo felt Juventus failing to show similar robust qualities over the course of the tie cost them dear.

"We made four mistakes in two games," he told Sky Sport.

"When you make a mistake four times in the first knockout round of the Champions League, it is normal that you go out.

"We had a good start, there was immediately an opportunity for [Alvaro] Morata. 

"We did not score and the incident in the area cost us an error and a penalty kick. Then we could have conceded another but in the second half we did well."

Juventus had greater control after the interval, although that was aided by Porto striker Mehdi Taremi being sent off for two bookings in quick succession after Chiesa's equaliser.

Further questions will now be asked over rookie coach Pirlo's suitability for one of the top jobs in European football.

Inter are 10 points clear of Juve in Serie A having played a game more, with the Bianconeri's grip on the Scudetto looking far looser than it has at any other time over the past decade.

"It will take a few days [to get over the Porto game]," Pirlo added. 

"We have to focus on the championship by facing every match in the best possible way, to try to move up the table." 

Around the time Massimiliano Allegri guided them to Champions League finals in 2015 and 2017, there would have been a sense of inevitability in any game where Juventus needed a 1-0 home win.

They would approach task with confidence and efficiency and probably win 1-0.

Andrea Pirlo's Juve needed a 1-0 win to progress to the Champions League quarter-finals on Tuesday but had not won a single game by that margin all season. They ended up going out on away goals to 10-man Porto after a thrilling and unwieldly slugfest.

Holding a 2-1 lead from the first leg at Estadio do Dragao. Sergio Conceicao's side lined up with something approaching a back six whenever they were out of possession.

Before the opening half hour was up in Turin, they had managed eight shots and were ahead through Sergio Oliveira's emphatically dispatched spot-kick.

Juve were a rabble. A shadow of the sleek winning machine under Allegri and every inch a team on their way to relinquishing a decade of domestic dominance in Serie A. 

In the years since a judiciously run sporting operation decided to go Galactico, the team beaten by Barcelona and Real Madrid in their most recent final appearances have bowed out to Ajax, Lyon and Porto – each time failing to get the job done on home turf in the second leg.

If this is how Andrea Agnelli oversees the rebuild of a great squad, perhaps UEFA should think twice before letting him revamp the entire Champions League.

No six appeal for Ronaldo

Of course, it is not all Cristiano Ronaldo's fault. He entered the match with 10 goals in as many Champions League home games for Juventus. Were it not for his stunning hat-trick against Atletico Madrid in 2019, they would have three consecutive last-16 exits to their name.

But in a career full of vintage nights, this was nothing of the sort for the five-time Champions League winner.

Ronaldo failed to touch the ball in the Porto area during the first half, missed a glorious chance to head a decisive goal from one of many sumptuous Juan Cuadrado crosses and turned meekly away as Oliveira's drilled free-kick went through the wall and beyond Wojciech Szezesny.

Adrien Rabiot headed home Federico Bernardeschi's corner to set up a grandstand finish and give Juve a joyless 3-2 win on the night, but Oliveira's unlikely brace proved decisive.

For Ronaldo and Juventus, the dream was over. As Erling Haaland continued his phenomenal goalscoring feats in Borussia Dortmund's similarly unhinged aggregate win over Sevilla and on the eve of Kylian Mbappe probably putting Barcelona and Lionel Messi out of their misery, the era might also be over.

Chiesa shows his class

Whoever the leading lights of the next generation prove to be, Federico Chiesa looks worthy of being part of the conversation.

The 23-year-old winger entered this game with two goals and as many assists in his past five outings, including Juve's vital away goal in Porto. He left it having produced a magnificent breakout performance on the biggest stage.

With Ronaldo missing in action, it was Chiesa and Alvaro Morata who took the fight to the visitors, the latter drawing a couple of superb saves from Porto goalkeeper Agustin Marchesin.

Four minutes into the second half, Ronaldo found a touch inside the area and an exquisite one at that. The lay-off was into Chiesa's stride and he opened his body expertly to stroke home.

Then a game that had cracked with low-level excitement exploded into a cacophony of incident and near chaos.

Taremi, such a nuisance to Juve during the first period, became a maddening inconvenience to his own team with two bookings in as many minute – the second for booting the ball away. Everyone can hear the referee's whistle nowadays, Mehdi.

Chiesa looked to have smuggled his and Juve's second, only for the monumental Pepe to hurl his body towards the ball with all the composure of someone trying to smother a live grenade. It hit the post and went wide.

Juventus's most dangerous attacker got a goal more in keeping with the beauty of his overall performance, arriving late at the back post to head Cuadrado's delicious right-wing cross into the top corner.

Chiesa then skipped effortlessly past Jesus Corona, although Marchesin stood firm to prevent the hat-trick. He was more than worthy of the matchball and the win.

In this muddled present dwarfed by a towering recent past, Chiesa provides measure of comfort and a promise of better days ahead for Juve.

Pirlo appears to have passed up his chance of being a part of those, while the clock is louder than ever before on the great Ronaldo – humbled by his dogged and defiant countrymen.

Sergio Oliveira scored twice as 10-man Porto dumped Juventus out of the Champions League with a scintillating away goals victory after a 3-2 second-leg defeat in Turin.

Juventus' task of overturning a 2-1 deficit from the first leg was compounded when Oliveira's penalty gave Porto a the lead after 19 minutes, but Federico Chiesa netted twice in 14 second-half minutes - either side of a red card shown to Porto striker Mehdi Taremi - to take the round-of-16 tie into extra-time.

Oliveira buried a stunning second goal of the night with five minutes left in the second period of extra-time, only for Adrien Rabiot to equalise and set up a tense finish.

Porto held on to spark wild celebrations on the visiting bench as Juve's quest for a first European title since 1996 ended in failure, heaping pressure on head coach Andrea Pirlo.

Juventus have announced midfielder Rodrigo Bentancur has tested positive for COVID-19.

The Uruguay international – who played the entire match as Juve defeated Spezia 3-0 in Serie A action on Tuesday – is asymptomatic, as confirmed by the club on Thursday.

Bentancur is now isolating and seemingly certain to miss Saturday's league game against Lazio in Turin.

"The club is in contact with the relevant health authorities for the definition of an effective implementation of the protocols required to allow the training and competition activities of the team group," Juventus said in a statement.

The 23-year-old's positive test also makes him a major doubt for the upcoming return leg of the last-16 Champions League tie against Porto.

Juve lost 2-1 in the first meeting, with the reverse fixture to take place next Tuesday.

Bentancur has made 33 appearances in all competitions this season, including 18 starts in the league for Andrea Pirlo's side.
