Is the Gianluigi Donnarumma-Milan relationship coming to an end?

Donnarumma made his debut as a 16-year-old for Milan in 2015, however, the Italy international is reportedly close to making the move to Serie A rivals Juventus.

Step forward Mike Maignan…

TOP STORY – DONNARUMMA OUT, MAIGNAN IN?

Lille goalkeeper Mike Maignan is poised to undergo a medical with Milan as Gianluigi Donnarumma edges closer to a blockbuster Juventus switch, according to widespread reports.

Donnarumma is set to become a free agent and the Milan star is yet to re-sign with the Rossoneri, who qualified for the Champions League.

Gianluca Di Marzio reports Milan are no longer waiting on Donnarumma as they step up their pursuit of Maignan, who will arrive in Italy on Tuesday after helping Lille to Ligue 1 glory.

ROUND-UP

- Fabrizio Romano says Massimiliano Allegri's priority is to take charge of Real Madrid, despite interest from former club Juve and Napoli in Serie A. Allegri is the favourite to replace Zinedine Zidane should he leave the Spanish capital. Despite securing a top-four finish, Andrea Pirlo is being tipped to leave Juve.

- There is set to be a coaching merry-go-round in Serie A this off-season. The front page of Tuesday's Corriere dello Sport says Porto boss Sergio Conceicao is favourite to succeed Gennaro Gattuso at Napoli, with the latter tipped to replace Simone Inzaghi at Lazio. Ex-Roma head coach Paulo Fonseca is the new first choice to join Fiorentina.

- Inter must sell one star – Lautaro Martinez or Alessandro Bastoni – due to their financial situation, according to Corriere dello Sport. Martinez has been linked with Barcelona and Real Madrid, while Bastoni has attracted interest from Liverpool and Manchester City. There is also speculation regarding the future of coach Antonio Conte and star Romelu Lukaku, who is reportedly wanted by Chelsea, Barca and Madrid.

- The Telegraph claims Manchester United are prioritising the signing of Borussia Dortmund star Jadon Sancho, who has long been tipped to join the Red Devils. Dortmund team-mate Erling Haaland is also wanted at Old Trafford, while Juventus superstar Cristiano Ronaldo has been linked with a sensational return.

- Tottenham are interested in re-hiring Mauricio Pochettino, reports the Independent. Pochettino is in charge of Paris Saint-Germain after replacing Thomas Tuchel in January but he was unable to oversee a successful title defence this season.

- Bayern Munich and Barcelona are targeting Liverpool's Georginio Wijnaldum on a free transfer, says Sky Sports.

Chelsea head coach Thomas Tuchel said the Champions League is "anyone's competition" to win after his side reached the semi-finals with a 2-1 aggregate victory over Porto.

Porto won the second leg 1-0 on Tuesday but it was not enough to overturn Chelsea's 2-0 first-leg victory.

Chelsea will play either Liverpool or Real Madrid in the final final, while Paris Saint-Germain will meet either Manchester City or Borussia Dortmund.

As Chelsea prepare for their eighth Champions League semi-final – the most of any English club – Tuchel told reporters: "We're in the competition and in the semi-final it is anyone's competition.

"In the semi-final, you need players fit, momentum, luck in the games.

The German added: "It is a very big achievement. You see when Chelsea was last in the semi-final.

"We are not used to being there. Once you are there, you play for the final. This is clear."

Chelsea will be appearing in their first Champions League semi-final since 2013-14 with a younger brigade of players compared to their upcoming opponents.

"When you look on the scoresheet last week, you saw two players [Mason Mount and Ben Chilwell] who scored their first goals in the competition," Tuchel said.

"When you look at Kylian Mbappe, Neymar, [Karim] Benzema or [Mohamed] Salah score, it is their 50th or 100th goal or something. We arrived with a very young team.

"We want a young team to turn it around. What a young team can do it run, fight and hang in there. It is an adventure for them. It is a big step to be here."

Sergio Oliveira described Porto's Champions League exit at the hands of Chelsea as "frustrating and sad", but said they must be "proud of our journey".

Mehdi Taremi's stunning acrobatic stoppage-time volley proved to be too little, too late as Porto could only beat the Blues 1-0 at Estadio Ramon Sanchez-Pizjuan on Tuesday.

A 2-0 victory in the first leg at the same ground in Seville ensured it was Thomas Tuchel's side who progressed to the semi-finals.

Porto showed no shortage of endeavour, but lacked ideas in the final third until substitute Taremi's sublime strike in the closing stages of the second leg.

The Primeira Liga champions could only muster two shots on target against a well-organised Chelsea side and midfielder Oliveira was left to rue their first-leg lapses.

He told TVI: "It's frustrating and sad, but it's football. We must be proud of our journey. Even in this tie, we had many moments when we were superior to Chelsea.

"We were penalised for two moments of a lack of attention, but it is part of football. These were team mistakes, not individual ones. The Champions League is over, now we have the [Primeira Liga] championship, which is our main goal."

Oliveira had no complaints over the way Chelsea set about finishing off the job.

He added: "With the advantage of two goals, I think Chelsea came to manage us. They wanted to calm down the tempo and our intensity. If we were two goals ahead, I think we would have done the same.

"Unfortunately we scored close to the end. Our aim was to score the first goal as quickly as possible, unfortunately we were unable to do that."

Mason Mount declared Chelsea are "ready for anyone" and confident they will beat Real Madrid or Liverpool in their first Champions League semi-final for seven years.

Mehdi Taremi's spectacular stoppage-time volley snatched a 1-0 victory for Porto in the quarter-final second leg on Tuesday, but Chelsea progressed 2-1 on aggregate at Estadio Ramon Sanchez-Pizjuan.

Thomas Tuchel's well-drilled Chelsea were untroubled until Taremi found the back of the net with a sublime acrobatic strike, which was only Porto's second shot on target in a drab encounter in Seville.

Chelsea have now reached the last four of the Champions League eight times, more than any other English team.

Mount, who scored in the first leg at the same venue last week, said the London club are not finished yet as they eye two trophies – with an FA Cup semi-final against Manchester City to come on Saturday.

Asked who he would like to play Madrid or Liverpool at the semi-final stage, Mount told BT Sport:  "We are ready for fight and battle. we get to sit down, watch and analyse it [the second leg at Anfield on Wednesday]  

"The best team will go through and we will be ready for anyone."

The England midfielder added: "We're buzzing. We're in a good position, we know we're playing well. The focus in every game is 100 per cent.

"We're going into each game with confidence that we're going to win. We've got a big end to the season."

Chelsea's second-leg defeat was their first in the Champions League this season and just a second in 18 games in all competitions under Tuchel, who replaced Frank Lampard in January.

Chelsea head coach Thomas Tuchel revelled in the club's Champions League semi-final berth after surviving a tense last-eight tie with Porto.

Porto claimed a last-gasp 1-0 win on Tuesday thanks to Mehdi Taremi's stunning acrobatic stoppage-time strike, but the Premier League side still advanced to the final four 2-1 on aggregate.

It was a tough battle at Estadio Ramon Sanchez Pizjuan – the same venue as last week's opening leg due to coronavirus protocols – with only three shots on target (one for Chelsea) throughout the return fixture.

But Chelsea saw off the Portuguese visitors over two legs to reach the semi-finals for the eighth time, more than any other English side in Champions League history.

"We accepted what was needed was a tough, tough fight," Tuchel told BT Sport as Chelsea prepare for their first semi-final appearance since 2013-14.

"Maybe on the television it was not so nice to watch but on the sidelines it was a very intense game, a very fast game.

"It was a tough fight and very hard to play against them to escape the pressure. They attack in a fluid and aggressive way. They change positions all the time. They come from behind, they overlap and you have to adapt to many movements. With every minute we did it better and better after a tough start.

"We defended well and deserved a clean sheet. We had the better chances - not a lot – but the better half chances. We could not finish it off with a goal so we had to hang in there and the guys did that.

"Overall we deserved to beat Porto. It was a tough 180 minutes."

It could be an all-English semi-final, with Chelsea set to face either Liverpool or Real Madrid in the final four.

LaLiga champions Madrid carry a 3-1 lead over Premier League holders Liverpool heading into Wednesday's second leg at Anfield.

Asked whether he would like to avoid Liverpool in the semi-finals, Tuchel added: "I like it in Champions League not to play in teams from your own league, it gives the feeling more of a European competition.

"The game is far from over and I will watch it for sure. It's a pleasure to watch it as a semi-finalist.

"It's a great achievement and tomorrow we will watch the game. Everything is possible. We will take what we get."

Mehdi Taremi's stunning stoppage-time volley was in vain as Chelsea reached the semi-finals of the Champions League despite a 1-0 defeat to Porto.

Chelsea took a giant stride towards the last four with a 2-0 win at Estadio Ramon Sanchez-Pizjuan last week and finished off the job at the same venue on Tuesday.

Porto were devoid of ideas in a drab second leg until substitute Taremi's sublime acrobatic strike gave them a glimmer of hope.

That proved to be too little, too late, though as Chelsea set up a showdown with Real Madrid or Liverpool in what will be their first appearance of the last four in Europe's premier club competition for seven years.

Porto, with leading scorer Sergio Oliveira back in the side, swarmed all over Chelsea in a positive start and Edouard Mendy was fortune to get away with a poor pass trying to play out from the back.

Mason Mount's speculative shot looped just wide and Reece James flashed wide in rare counter-attacks from the Blues, with Porto not allowing them to settle.

Corona wasted a golden opportunity to halve the deficit when he blazed high and wide after Ben Chilwell failed to deal with a high ball in a frantic first half which the Primeira Liga champions had the better of, but failed to test Mendy.

An unmarked Christian Pulisic wasted a chance to put the London club out of site when he failed to make a proper connection with Chilwell's cross early in the second half.

Wilson Manafa blocked a Mount shot after the in-form midfielder surged into the penalty area, with Chelsea posing much more of an attacking threat.

Sergio Conceicao introduced Taremi after 63 minutes and the striker had half a chance soon after coming on, but failed to generate enough power on a header that was comfortably saved by Mendy.

Taremi gave Porto victory on the night with a brilliant bicycle kick, but the damage had already been done.

Paris Saint-Germain are 90 minutes away from avenging their Champions League final defeat to Bayern Munich.

The Ligue 1 champions go into the return leg of the quarter-final with Bayern at the Parc des Princes with a one-goal advantage and with their talisman eyeing a slice of history in Europe's elite club competition.

If PSG complete their task and ensure there is to be a different name on the trophy this year, then in-form Chelsea will fancy their chances of lifting club football's most sought-after prize.

Led by the man who guided PSG to the showpiece last season, the Blues hold a comfortable lead in their last-eight encounter with Porto.

All the evidence points to Chelsea going through to the semis as they look to replicate their team of 2011-12, who overcame Bayern in a penalty shoot-out in the final.

Here we look at Tuesday's quarter-final clashes with the help of Opta numbers.

Paris Saint-Germain v Bayern Munich - Omens against holders as Mbappe eyes record

The holders must score at least twice if they are to keep their hopes of retaining the trophy alive, having lost the home leg of this rematch of last season's final 3-2 at the Allianz Arena.

And history is against Hansi Flick's side turning it around. 

PSG have won all four previous games when they have hosted Bayern in European competition between 1994 and 2017.

Bayern have been eliminated on each of the most recent four occasions they have lost the first leg of a Champions League knockout tie, while only three of the past 50 teams to lose the first leg at home in the competition have progressed.

However, one of those teams did so against PSG, Manchester United coming from behind to knock out the Ligue 1 side at the Parc des Princes in the last 16 in 2018-19.

If PSG are to unseat the champions, they will likely look to Kylian Mbappe.

Mbappe was on target twice in the first leg and has eight goals in as many appearances for PSG in the Champions League this season. If he nets again on Tuesday, he will set a new record for the most goals by a French player in a single Champions League campaign, surpassing David Trezeguet in 2001-02 and Wissam Ben Yedder in 2017-18.

Should he score against Bayern once more, he will have netted in four consecutive knockout appearances for the second time in his career, having done so with Monaco in 2017, and would become the first PSG player to achieve that feat. 

Chelsea v Porto - Seville shock unlikely to be on the cards

Thomas Tuchel's Blues will not have the benefit of any home comforts when Chelsea attempt to finish the job and reach the last four having won 2-0 in the first match.

As with the opening leg, Chelsea and Porto will do battle in Seville due to coronavirus restrictions, with the odds firmly in the London club's favour.

Indeed, there have been only four previous instances of a team progressing after losing the home leg of a Champions League knockout tie without scoring – Ajax in 1995-96 v Panathinaikos, Inter in 2010-11 v Bayern, United in 2018-19 v PSG and Tottenham in 2018-19 v Ajax.

Porto pulled off one of the shocks of the Champions League when they knocked out Juventus in the last 16, however, they will need to reverse a worrying trend if they are to do the same to Chelsea.

Since beating Leicester City 5-0 in the group stages of this competition in December 2016, Porto are winless in seven matches against English sides in the Champions League (D2 L5), scoring only twice while conceding 16 goals themselves.

The smart money is on that streak continuing, with Chelsea unbeaten in the Champions League this season (P9 W7 D2 L0).

They could become the first Premier League team to go unbeaten across their first 10 games in a season in the competition since Liverpool in 2017-18 (11 games).

A solid defence has been key to their success in Europe this term, as Chelsea have kept seven clean sheets in nine Champions League matches this season, the joint-most along with Manchester City; the last side to keep more clean sheets in a single campaign in the competition was Juventus in 2016-17 (nine).

The Blues are looking to keep a clean sheet in four consecutive matches in the tournament for the first time since a run of six ending in March 2008. 

Great credit for that run must go to goalkeeper Edouard Mendy, who can tie the record of Fabian Barthez (eight with Manchester United in 2002-03) for the most consecutive Champions League games won by a goalkeeper for an English club with another triumph over Porto.

Thomas Tuchel insists he will not hide from the challenge of winning trophies at Chelsea as they prepare for a significant Champions League and FA Cup double bill.

The Blues face Porto on Tuesday in the home leg of their quarter-final tie in a commanding position, having won 2-0 in the first fixture.

On Saturday, they will meet quadruple-chasing Manchester City in an FA Cup semi-final, with the prospect of meeting either Leicester City or Southampton in the final.

Chelsea remain in a battle for a top-four finish in the Premier League but head coach Tuchel has his sights set on delivering silverware, despite only taking over from Frank Lampard in January.

Asked if the Champions League is Chelsea's best chance of a trophy in 2020-21, Tuchel replied: "Maybe when you are in the final.

"We are in the second leg of the quarter-final of the Champions League. You will not find any team who do not have the goal to reach the semi-final.

"We are in the semi-final of the FA Cup and have the chance to arrive in the final. If we arrive in the final then we have the chance to win.

"There is nothing to hide. This is a club that has a culture, a structure to win titles and win games consecutively. Chelsea is the club that has the culture and the history and mentality to do so.

"I am here to win titles, I am here to win games and as a result, win titles. This is what I demand of myself so why should we now say anything different?

"But, honestly, we can talk for hours and hours but tomorrow is the game to play and there is no tougher match than the next game, there is no tougher obstacle than the one in front of you and we should not get lost in dreams, hopes and speeches or whatever.

"We are here to perform in the second leg of the quarter-final, this is what we do and then hopefully after tomorrow we can talk about a semi-final."

Goals from Mason Mount and Ben Chilwell secured Chelsea's first-leg win and they are yet to lose a game in this season's competition.

Porto, meanwhile, have only won once in their past 20 knockout games as the away side, while only four teams have previously progressed in this competition after losing a home first leg of a tie without scoring.

Still, Tuchel believes Porto have an easier challenge as they can only go all out for victory in Seville, where the first leg was also held due to coronavirus restrictions.

"We don't approach games like this [passively] or change the approach," Tuchel said. "For us, it is important that we focus on us, play the best game possible as this increases the chances to have a result.

"In terms of a result, it is easier for Porto because they need to score three goals to get through, for them if it is clear. For us, if we start in this way then we could completely lose our heads. I hope we embrace the challenge and feel it."

Sergio Conceicao says Porto are confident they can mount a storming fightback and knock Chelsea out of the Champions League.

The Primeira Liga champions have a mountain to climb in the quarter-final at Stamford Bridge on Tuesday after suffering a 2-0 home defeat in the first leg last week.

Porto have won only one of their 20 knockout stage matches on their travels and that was back in 2004 against Deportivo de La Coruna at the semi-final stage.

Conceicao warned Chelsea that his side are ready to roll up their sleeves and seal a place in the last four.

"There are many moments overs the years that can be examples of overcoming and believing," said the Porto head coach.

"We are confident. We know that we are going to face a difficult obstacle, but we are here to give the answer that we have to give. The feeling of representing this historic club and its DNA is always on the pitch."

Conceicao says Porto will not go out all guns blazing in London.

He added: "We have to be a compact, cohesive team. It is necessary to score goals, but also not to suffer.

"In the first leg we played a good game, but it was not good enough. If it were, we would have won the game. We will try to improve even more what was a good performance by the team.

"Over 90 minutes for FC Porto it requires the ability to believe and be resilient. We always try to enter with that spirit. We are ready to go to the fight and to fight."

Thomas Tuchel says Chelsea retain "faith and trust" in struggling forwards Timo Werner and Kai Havertz.

Both players were substituted with 25 minutes left in the 2-0 Champions League win over Porto in Seville on Wednesday.

Tuchel said after the quarter-final first leg that the two players had not given him what he was looking for.

But ahead of the short trip to play Crystal Palace in the Premier League on Saturday, he insisted both players remain a key part of his plans and that his substitutions were specific only to that match.

Tuchel accepts Werner is lacking in confidence but does not have any concerns over Havertz.

Werner has been directly involved in more Premier League goals this season than any other Chelsea player (11, with five goals and six assists). 

However, the Germany striker has scored with just one of his last 42 shots in the competition, a strike against Newcastle United in February.

"Look at the games Porto played in the Champions League," said Tuchel in defence of Werner and Havertz.

"If you can show me any nice, fluid and pretty games of any opponent we can talk again. I did not find it. 

"They make your life very tough, especially for offensive players. They went through the group with 13 points. You can ask in the group how easy it was to play against them. 

"They did not have the easiest task up front. They had a big impact defensively and they worked hard for us, both Kai and Timo. 

"It was difficult for them to find spaces and create something, so we changed after 65 minutes but we will not lose faith and trust. 

"We accept sometimes it's hard sometimes to have a big impact. Maybe Timo misses a bit of confidence in his finishing but Kai, I feel, is very self-confident. 

"There are no bigger concerns. It was just in this game we tried to change the momentum."

Chelsea are yet to lose on the road under Tuchel in the Premier League (W3 D2).

The Palace clash comes after a dramatic week for the Blues, with the Porto win following up a shock 5-2 home reverse against West Brom.

Tuchel is keen to ensure his players do not get too up or down based on one result.

He added: "It's my job to learn every day and from every game, from every situation we have to face. 

"I don't have a big conclusion after the two games with the down and up we had in terms of results. 

"It's important to share experiences and make my experiences with the team. It's the first time we lost, a big loss, an unexpected loss in a weird game. 

"We have a lot of positives together so we needed to adapt and react to it. 

"I'm very happy we bounced back immediately. We were unlucky in some situations in the game. It's important for us now that we went through this. 

"Hopefully we can start a winning streak again."

Palace have kept five clean sheets in the Premier League at Selhurst Park since the turn of the year, two more than in the entirety of 2020.

But manager Roy Hodgson has lost six consecutive Premier League matches against Chelsea. 

The only opponent he has lost seven consecutive games against as a manager in the competition is Tottenham in a run that lasted between 2011 and 2019.

Porto are not yet giving up hope of reaching the Champions League semi-finals despite a frustrating 2-0 first-leg defeat to Chelsea in the last eight.

In their designated home leg, although both matches are being played in Seville, Porto enjoyed much the better of the first half, having eight shots to Chelsea's one and a superior expected goals (xG) total of 0.86.

However, the Premier League side – who had a half-time xG of just 0.05 - scored with that sole attempt through Mason Mount.

That lead was extended in the closing stages by Ben Chilwell, meaning Porto must now win by two goals in the second leg to maintain their European hopes.

While Wednesday's defeat was tough to take, Porto have already delivered an unlikely second-leg result in their run to the quarters, advancing against Juventus on away goals after extra time despite playing more than an hour with 10 men.

And midfielder Marko Grujic told Eleven Sports: "It is difficult to accept this result because we had eight shots in the first half to their one.

"We showed that we have quality and in the second leg will try to turn the tie.

"Porto have shown in the Champions League that anything is possible. With great spirit and preparation, nothing is impossible."

Grujic made three tackles and won all five of his aerial duels in a battling display typical of this Porto side.

Indeed, as well as outshooting Chelsea 12-6 across the 90 minutes, Porto won 62.4 per cent of the sides' duels while conceding six fewer fouls.

Sergio Conceicao felt Chelsea's experience told and bemoaned the nature of the goals Porto conceded, Chilwell's coming following a Jesus Corona mistake - the first error leading to a goal his side have made in the competition this season.

But the coach could not question Porto's spirit.

"I believe we played a good game," he told a news conference. "The projections for the second leg don't change, they are the same ones we had before the first leg.

"We believe in what we do, we have confidence in our squad. When it comes to the game strategy, I think we were tactically strong tonight.

"But there were two individual mistakes that caused two goals of the opponent. We deserved more than the result we've got. We didn't deserve to be losing 2-0 at half-time of this tie.

"We are at half-time. And we will fight until the last minute of the next 90 minutes to try to turn this tie around.

"We know it's going to be difficult, we know this is the Champions League and we are a club that doesn't belong to the big five [leagues].

"I could feel it today in relation to the referee's decisions. It's not an excuse.

"Also, we don't have the same capacity of Chelsea when it comes to their experience and individual talents. We can't forget that Chelsea brought off the bench [Christian] Pulisic, [Olivier] Giroud, [N'Golo] Kante, Thiago Silva...

"And we brought in the boys and left some other youngsters on the bench.

"It doesn't mean they don't have quality, they do have quality. And playing games like tonight's, they get more experience which is crucial at this level where a small mistake is punished by your opponents."

Chelsea head coach Thomas Tuchel admitted Kai Havertz and Timo Werner were replaced following underwhelming performances in Wednesday's Champions League success against Porto.

Mason Mount and Ben Chilwell scored as Chelsea drew first blood against Portuguese outfit Porto in the quarter-final tie with a 2-0 victory in Seville midweek.

It was a necessary response for Tuchel, whose 10-man Chelsea were sensationally humbled 5-2 by lowly West Brom in the Premier League last time out.

But Chelsea did not have it all their own way against Porto, who were the better side for periods of the game and only just second best in terms of expected goals (xG) – 1.8 to 1.7 in the former's favour.

Havertz and Werner particularly struggled, the German duo replaced by Olivier Giroud and Christian Pulisic with 25 minutes remaining, and Tuchel explained his changes.

In his last 29 games in all competitions, Werner has missed 20 big chances, with an xG of 10.5 and 3.5 shot conversion rate.

"I accepted that it was a tough match for Timo and for Kai today," Tuchel told reporters after Chelsea won consecutive away knockout fixtures in the Champions League for the first time since 2004. "They did not have their best day but we did not deliver so well [for them].

"The connection between the deep seven players that we needed for the build-up and the front three, we lost a bit the connection to them.

"The balls we delivered were not the best balls and I could feel our two German players up front, Kai and Timo, did not play on their highest level today so I wanted to have an impact from the bench."

No side has conceded fewer goals (two) or kept more clean sheets (seven) in this season's Champions League than Chelsea (level with Manchester City on both counts).

Since Tuchel's first game in charge of Chelsea (January 27), no goalkeeper playing for a top-five European side has kept more clean sheets in all competitions than Edouard Mendy (10).

Tuchel added: "Christian has a good momentum, Oli has waited long and has good experience and memories of this stadium. We wanted to give the sign that we keep on going [in the game].

"This is the mentality in general that I like about this club and this team and that we want to implement. Once you lead, it is very hard to not play with the mentality of having something to lose. You want to keep what you have.

"But you need to go to try to win the next half and go and try to win the next duels and try to score the next goal. The best way to defend is to attack. The best way to impress the opponents is to have ball possession to be couraged and to always be a threat.

"I am happy about the impact of our substitutions. It is absolutely necessary that we have this bond between the players and we have this impact from the bench physically, but also with quality. That's why we are super happy with a big win today. The job is half done and we are aware of that and we need another top performance on Tuesday."

Thomas Tuchel feels Chelsea's response to their humiliating West Brom defeat by beating Porto 2-0 in the Champions League will increase the team's togetherness and trust.

Tuchel had overseen 14 games without defeat since replacing Frank Lampard in January until Saturday, but his unbeaten run as Blues head coach came to a stunning end at Stamford Bridge.

The fit-again Thiago Silva was sent off only 29 minutes into his first game for two months and second-bottom West Brom capitalised in ruthless fashion after Christian Pulisic opened the scoring in a match that ultimately finished 5-2 to Sam Allardyce's men.

It was only the second time in Premier League history that Chelsea had conceded five times at home, and to make matters worse, Kepa Arrizabalaga and Antonio Rudiger were involved in a training ground bust-up in the wake of that defeat.

But on Wednesday in Seville, where both legs of their quarter-final will be played due to coronavirus travel restrictions, Chelsea were clinical.

Mason Mount's first-half opener was added to late on by Ben Chilwell, who pounced on a defensive error, giving the Blues two away goals and putting them in complete control of the tie, much to the satisfaction of Tuchel after a difficult few days.

When asked if he had been confident of a good response to the Baggies defeat, Tuchel told BT Sport: "I was pretty sure about that because I saw a response immediately after the game in the dressing room and the next day, on Monday. I was pretty sure, it wasn't a big concern.

"We had a big loss of course, but it was our responsibility, we accepted it, me included, for all of us we were ready to respond.

"There will always be setbacks in sports. The biggest challenge is to bounce back.

"We had a lot of wins together, a lot of excellent results together, then we had a loss together and now we have a reaction after a loss together.

"That brings us closer together and increases the trust, and it was important for the guys to have straight after this defeat a clean sheet. It was excellent."

Chelsea have become accustomed to clean sheets this term, with Wednesday's shutout their seventh in the Champions League this term, taking them level with Manchester City as leaders in this regard.

It was also Edouard Mendy's 10th clean sheet across all competitions since Tuchel was appointed in January, more than any other goalkeeper in Europe's top five leagues.

But the scoreline did not give a true reflection of the game, with Porto the better side for periods of the game and only just second best in terms of expected goals (xG) – 1.8 to 1.7 in Chelsea's favour.

The second leg will take place on April 13, also at Sevilla's Ramon Sanchez Pizjuan, with Chelsea set to be the home side on that occasion.

Chelsea have one foot in the Champions League semi-finals thanks to a 2-0 away win over Porto, with Mason Mount's first-half effort added to late on by Ben Chilwell.

Thomas Tuchel's men came into the contest on the back of an embarrassing defeat to struggling West Brom but managed to put that behind them on Wednesday, even if they were not entirely impressive.

Back on the scene of their 4-0 group-stage win over Sevilla due to coronavirus travel restrictions, Chelsea were second best for significant parts of the game but opened the scoring through Mount just past the half-hour mark.

Porto, without key men Sergio Oliveira and Mehdi Taremi due to suspension, were unable to apply the required finishing touch to some of their eye-catching build-up play and a defensive error gifted Chilwell the opportunity to seal what looks like a commanding first-leg advantage.

For all the talk of Porto representing a dream draw for Chelsea, it was Sergio Conceicao's men who looked brighter in the early exchanges, with Luis Diaz having an effort crucially blocked a few moments before Matheus Uribe saw a fine volley land on the roof of the net rather than in it.

Chelsea had another escape in the 24th minute as Edouard Mendy just about managed to stop Otavio scoring direct from a corner and Zaidu Sanusi put the rebound over.

But a period of Chelsea pressure followed and they capitalised, Mount producing a gorgeous turn to beat Chancel Mbemba on the edge of the box before firing into the bottom-left corner.

Porto began the second period encouragingly as well, Diaz seeing a curling effort go agonisingly wide from 20 yards after excellent work from Wilson Manafa.

An effort from distance at the other end – courtesy of Antonio Rudiger – led to Agustin Marchesin spilling at the feet of Timo Werner, who squared to Kai Havertz and he missed an open goal, though his blushes were spared, to a certain extent, by the offside flag going up against his compatriot.

Not that Chelsea were made to rue that situation as, soon after Christian Pulisic had hit the post on the break, Chilwell made sure of the victory as he pounced on a loose touch by Jesus Corona and tucked into an empty net after rounding Marchesin.

Bayern Munich host Paris Saint-Germain in a repeat of last season's final and Porto meet Chelsea at a neutral venue in Wednesday's Champions League quarter-final first legs.

Bavarian giants Bayern beat PSG 1-0 to win the trophy last year and have remained unbeaten throughout this season's campaign.

But the reigning European champions are without injured star man Robert Lewandowski and do not have the best of records in this fixture.

Porto will be looking to build on their impressive win over Juventus in the last round when they take on Chelsea in what will be classed at their home leg at Sevilla's Estadio Ramon Sanchez Pizjuan.

The Portuguese side famously lifted the trophy in the 2003-04 season under Jose Mourinho, who was Chelsea boss the last time they reached this stage of the competition seven years ago.

Bayern Munich v Paris Saint-Germain: Can PSG exact some revenge against Lewandowski-less holders?

Not since March 2019, when going down 3-1 to Liverpool at the last-16 stage, have Bayern tasted defeat in Europe's premier club competition.

That is a run spanning 19 games and they could become the second team ever in the competition to go 20 without losing after Manchester United (25 between 2007 and 2009).

The Bavarians have won all but one of those matches, including a victory in last August's final, but they have a negative overall record against Wednesday's opponents.

PSG have won five and lost four of the previous 10 Champions League encounters, though this will be just their second meeting in the knockout phase.

Indeed, Bayern have only lost more Champions League matches against Real Madrid (10) than PSG, while against no side have the Ligue 1 club won more games in the competition.

Bayern will also be without Lewandowski, who has 15 goals in 13 Champions League games since Hansi Flick took over in November 2019 - the most of any player in the competition across that timeframe.

PSG will have their key men available, with Kylian Mbappe looking to build on a return of 35 goal involvements in 33 games for the club in the Champions League.

The France international has scored six goals in seven games in this season's competition, including four goals across the two legs with Barcelona last time out, making this his joint-best campaign alongside 2016-17.

Porto v Chelsea: Conceicao's charges hoping to jump quarter-final hurdle

This will be the eighth meeting between Porto and Chelsea in the Champions League, the Blues winning five and losing just one of those previous encounters.

Only against Madrid (six) have Porto lost more matches, and they were eliminated 3-2 by Chelsea the only previous time they met in the knockout stages in the 2006-07 last 16.

That was a familiar story, Chelsea having won 75 per cent of their Champions League games against Portuguese sides - only versus Spanish teams (13) have they won more, a record they added to with victories over Atletico Madrid in the last 16.

Should they overcome Porto here, Thomas Tuchel - appointed as Frank Lampard's successor in January - will become just the second Chelsea boss to win his first three Champions League knockout-stage matches after Roberto Di Matteo in 2011-12.

Porto are certainly no strangers to the last eight, reaching this stage for the third time since going all the way in 2003-04, but they have won only one of those six ties.

At 38 years and 40 days, it could be an occasion to remember for veteran defender Pepe, who is in line to become the oldest outfield player to feature in a Champions League quarter-final since Manchester United's Ryan Giggs (40y, 123d) in April 2014.
