Jurgen Klopp opened up on the half-time team talk that helped Liverpool fend off a Villarreal comeback to reach the Champions League final.

The Reds had arrived in Spain holding a 2-0 aggregate lead thanks to a dominant showing at Anfield but contrived to squander it during a chastening first half at El Madrigal.

However, a much-improved second-half showing punctuated by goals from Fabinho, Luis Diaz and Sadio Mane helped secure passage to a third Champions League final appearance in just five seasons.

And, when asked how he had masterminded that change of fortunes, Klopp told BT Sport: "It feels like the first in 20 [years], it's outstanding, because we made it obviously pretty tricky for ourselves. 

"We knew before that these kinds of things can happen; it's all about in life all the time how you react when things don't go your way. 

"Getting the first goal after two-and-a-half, three minutes, that's obviously not what you wanted, momentum on their side.

"After the first half I told the boys, 'Yes, they have momentum but they don't own it! In one situation we can get it back.'

"We were calm because I accept it 100 per cent that if Villarreal plays the second half like they play the first and we played the second half like the first then they will be in the final.

"The perception was like this, everything looked more like they will score the 3-0 than we will score the 2-1 but we are still here so we could give it a try and that's what we did."

The German went on to reveal that his half-time rallying cry also featured elements of important tactical advice to his players.

He explained: "The problem with the half-time was that we knew what was wrong because it was obvious, but we didn't have the situations to show where we did it right.

"Respect to Villarreal, I have to say; stadium, team, coach, it's unbelievable what they set up, they put us under pressure. 

"[It was] man-v-man all over the whole pitch, we didn't play football at all, we didn't get momentum back.

"We have to play in the right spaces, we have to force ourselves in the game to start playing football. 

"[When] we broke the lines and we found Naby or Trent in the half-spaces and the front three were more flexible and not fixed in their positions, all of a sudden we were in the game, scored goals and made it happen. 

Liverpool's final opponents will be confirmed on Wednesday when Real Madrid and Manchester City do battle in the second leg of their semi-final tie.

Of his side's prospective opponents, Klopp added: "Yes, I will watch it! Whoever it will be, it will be massive. 

"Whoever wins tomorrow night will deserve the result and then we'll face each other in Paris."

Mohamed Salah would rather face Real Madrid than Manchester City in the final of the Champions League in Paris as they target the quadruple after seeing off a spirited Villarreal performance in the last four.

Liverpool survived a huge scare in Spain to reach their 10th European Cup/Champions League final, with Fabinho, Luis Diaz, and Sadio Mane scoring second-half goals after Villarreal wiped out the Reds' first-leg lead in an unbelievable first half.

Liverpool have become the first team to reach the finals of the European Cup/Champions League, the FA Cup, and the League Cup in a single season, and trail City by just one point in an absorbing Premier League title race.

The Reds' incredible form has led to talk of Jurgen Klopp's team lifting four major trophies at the end of the campaign, with Salah hoping to complete the quadruple against Madrid having been substituted after suffering an injury in Liverpool's 2018 final loss to Los Blancos.

"Yeah, [it's a target] for sure," he told BT Sport. "Maybe not in the beginning of the season if I'm honest, because I always focus on the Champions League and the Premier League, but now we are close for everything, so why not? 

"I think after we beat City in the semi-final of the [FA] cup [Liverpool believed it was possible], but in the Champions League, from the beginning we were playing unbelievable games, we had a really tough group and we beat everybody, so I said from that time we could win the Champions League this year.

"I want to play Madrid, I have to be honest. City is a really tough team, we played against them a few times this season, but I think if you ask me personally, I would prefer Madrid.

"Because we lost in the final against them, I want to play against them, and hopefully win against them as well."

Salah assisted Fabinho's vital 62nd-minute goal in Spain, taking his tally to an incredible 45 goal contributions in all competitions this season (30 goals, 15 assists), and the Egypt international revealed he had set himself a target of 40 goals before the campaign began.

"I just give the team everything, we have to focus for the team because we fight for everything, we won one trophy already, we are in the final, we continue to fight for the Premier League and we are in a final against Chelsea [in the FA Cup]," he added.

"I just focus, and try to train hard. I know what I want at the end of the season, so hopefully I can get what I want. 

"Before the season starts, I know what I want from the season, individually and collectively. The collective is the most important, [but] I'm nearly there, I have a big expectation for myself. 

"Honestly, I never said this before but before the season started, I was like 'okay, I'll go for 40 goals this season, and 10 or 15 assists'. I need to focus on the goals now!"

Reds defender Virgil van Dijk, meanwhile, hailed winger Diaz for his impact after the January arrival changed the game as a half-time substitute, but refused to join Salah in stating a preferred final opponent.

"The way he goes one versus one, it doesn't really matter who he is facing, he just goes at you without any fear," Van Dijk said of Diaz. "And if he loses it, he wins it back and goes again. That is very difficult to defend.

"Any team that we face in the final of this competition will be a nightmare to play against. We know City but they know us too. We know how intense those games are. Real Madrid is Real Madrid. Such a big club and an in-form striker [Karim Benzema]."

Liverpool's Champions League final opponents will be revealed when Pep Guardiola's City travel to the Spanish capital on Wednesday, attempting to defend a 4-3 first-leg lead to set up an all-English final.

Trent Alexander-Arnold offered a scathing assessment of Liverpool's first-half performance at Villarreal but is willing to accept an occasional bad 45 minutes as long as they recover as they did to reach the Champions League final.

Villarreal drew level on aggregate, going up 2-0 on the night, before goals from Fabinho, Luis Diaz and Sadio Mane in the second half restored Liverpool's lead and progression to May's final in Paris.

It will be Liverpool's third Champions League final under Jurgen Klopp, following a defeat to Real Madrid in 2018 and triumph over Tottenham in 2019.

Speaking after a thrilling 3-2 win, Alexander-Arnold made reference to the tricky paths that led to those finals, asserting the volatile nature of Tuesday's victory was just a continuation of a theme.

"We never tend to make these Champions League semis easy for ourselves, thinking back to Roma away, Barca at home and now here – difficult, very difficult," Alexander-Arnold told BT Sport post-match.

"We never played football that first half. We never picked up any of the second balls at all, and they kind of played the game the way that they wanted to, and we allowed them to do that.

"Second half, we came out and played the way that we needed to play, and controlled the game a lot better. One bad half over two legs, we can concede that as long as we got the job done."

With the win, the Reds will face the winner of Wednesday's semi-final second leg between Real Madrid and Manchester City.

"It's always nice to get the job done on the Tuesday," he said. "We can watch the game tomorrow, knowing that we're going to be there, and who we're going to play.

"I'm sure it will be a good game. If it goes by anything last week, we'll be in for another amazing game. Either opponent kind of deserves to get to the final, so we'll see who we'll get."

Given the stakes involved, Champions League semi-finals don't tend to be fertile ground for managers to learn lessons about their teams.

But for Jurgen Klopp, Tuesday's win over Villarreal provided more than just a ticket to the showpiece fixture of Europe's premier cup competition in Paris later this month.

It also handed the German several important insights into his squad that may prove key to a quadruple bid that was extended by victory in Spain.

Klopp probably did not appreciate the start of that learning process – an unexpectedly poor first-half performance he would prefer to forget.

In possession of 'the most dangerous lead in football', it was key that the visitors did not concede an early goal that would boost the home crowd's belief. 

And yet they conspired to do exactly that, twice failing to prevent crosses before Boulaye Dia poked home to ignite El Madrigal.

That early goal set the tone for a first half that saw Liverpool harried (65.5 per cent passing accuracy) and bullied (45.6 per cent duels won) out of the game for large periods.

And so they could have no complaints over going in at half-time level on aggregate fearing that Villarreal would become only the second team to overcome a two-goal deficit in a Champions League semi-final.

Liverpool were, of course, the ones who pulled off that previous comeback, overturning Barcelona's three-goal advantage en route to winning the 2018-19 edition of the competition.

Yet, with their first-half attempts to prevent history repeating itself having failed, it seemed inevitable that changes were coming at the break.

Perhaps the only surprise was that Klopp limited himself to just one alteration, introducing Luis Diaz in place of Diogo Jota but leaving his starting midfield trio alone.

However, it was hard to argue with the results of that minor tweak: a consummate second-half performance that turned a 2-0 deficit into a 3-2 win.

That outcome is good news for Diaz, whose match-high four shots and well-taken goal underlined the brilliance of another sparkling outing.

But it might not be for Jota, who won just two of six duels and completed six of nine passes before getting the half-time hook.

There were also contrasting fortunes in midfield, where Naby Keita provided the most notable recovery from a midfield three that looked lost in the opening 45 minutes.

With Jordan Henderson going through a vigorous warm-up just after half-time, it did not look like the Guinean would last much longer.

But, as was the case with his colleagues in the engine room, he went up a level en route to posting 21 passes in the opposition half, three tackles, and 11 possession regains (more than any other player on the pitch) by full-time.

With the big games coming thick and fast in the weeks ahead, the consequences of these performances are likely to stretch beyond simply securing Liverpool's third Champions League final appearance under Klopp.

As he guides an unlikely quadruple bid towards a dramatic conclusion, the manager now has an even clearer idea of which players he can rely on to deliver on the biggest of stages.

Liverpool overcame a spirited Villarreal performance to book their spot in the Champions League final with a 3-2 away win, netting three second-half goals after seeing their first-leg lead wiped out in Spain.

Boulaye Dia handed Unai Emery's men an early lead in front of a boisterous home crowd, before Francis Coquelin stunned the below-par visitors by wiping out their aggregate lead on the stroke of half-time.

But Liverpool grew into the game after their dismal start, and after Geronimo Rulli failed to make a routine stop from Fabinho's effort, half-time substitute Diaz headed home to send Jurgen Klopp's men to the final.

Sadio Mane raced clear to round Rulli and roll home a late third to make the result safe before Etienne Capoue was sent off late on, keeping the Reds on course to cap an incredible season by winning four major trophies.

After failing to record a single shot on target at Anfield, the Yellow Submarine needed just three minutes to open the scoring, Dia tapping home after Capoue turned Pervis Estupinan's delivery across goal.

Gerard Moreno saw a close-range header blocked as the visitors produced a dreadful first-half performance, and the Reds' advantage, which looked to be decisive prior to kick-off, was wiped out when Coquelin sparked wild scenes by heading Capoue's cross into the top-left corner.

Trent Alexander-Arnold struck the top of the crossbar with a deflected effort as Liverpool improved after the break, before Fabinho drilled a low shot through the legs of Rulli to restore the visitors' aggregate lead after 62 minutes.

Diaz went close to bending home a superb second moments later, but was on hand to nod home Alexander-Arnold's cross after 67 minutes and put the Reds back in full command of the tie.

The tie was settled once and for all when Mane took advantage of another Rulli error after 74 minutes, rounding the keeper well outside his area before rolling home to secure Liverpool's progress, with Capoue then dismissed for a second yellow card after fouling Curtis Jones.

Former Villarreal star Robert Pires believes Liverpool are "the best team in Europe", but insists the Yellow Submarine can overturn a 2-0 first-leg deficit to reach the Champions League final.

After a routine Liverpool win at Anfield last Wednesday, Villarreal will attempt to become just the second team to overturn a two-goal first-leg deficit in a Champions League semi-final (after Liverpool's 4-3 aggregate win over Barcelona in 2019).

Villarreal did not manage a single shot on target in their away reverse, but Pires' former club did win their only previous home game against Liverpool in European competition (a 1-0 win in 2015-16's Europa League semi-finals).

Although Pires said quadruple-chasing Liverpool are the best team on the continent, he does not think the result is a foregone conclusion on Tuesday.

"Of course Villarreal can go through," he said in comments reported by AS. "We know how complicated it is, we cannot deny that. We know the level of Liverpool and their quality, they are very good and very strong, but Villarreal has not said the last word.

"For me, Liverpool is the best in Europe at the moment and that makes it a great challenge. For this reason, Villarreal, which is a very solid team, suffered a lot in the first leg. But they came out alive, and knowing Emery and the quality of this team, I wouldn't be comfortable.

"To that they must add a bit of luck, we know that these comebacks must have that point of fortune to turn the tie around. I tell people that if the player feels that the fans are with you and push, anything is possible. 

"Hopefully Villarreal will reach the final in Paris. That is my wish, I would very much like it to be."

Villarreal have never lost a home match in the Champions League knockout stages, although they have drawn five of their seven such fixtures.

Before Pires joined the Yellow Submarine, for whom he made 131 total appearances across four seasons, he lined up as an opposition player for the club's only previous Champions League semi-final appearance, with Arsenal.

The Gunners reached the final with a 1-0 aggregate win after clinging onto a goalless draw in Spain, with Jens Lehmann saving Juan Roman Riquelme's late penalty, and Pires said his memories of that contest make him believe Villarreal will provide Liverpool with a stern test.

"This team is not eliminated, far from it," he added. "I played the other semi-final with Arsenal and we also had an advantage, so we hoped to get through without suffering. And the reality was very different.

"We suffered like dogs in that game. We came from eliminating Juventus and Madrid, we were very confident and secure, but we arrived here and had a really bad time. I don't know what happened to us, but it was the game in which we suffered the most of all. 

"That's why I think Villarreal can give Liverpool a cane. I know, I've lived it."

Villarreal are unbeaten in 12 home matches in all competitions, winning eight, and recorded an incredible 1-0 success against Bayern Munich in their last home Champions League outing.

Real Madrid and Villarreal have it all to do when they host Manchester City and Liverpool respectively in the second legs of their Champions League semi-final ties in midweek.

Fresh off the back of winning a second LaLiga title in three seasons, Madrid are aiming to overturn a 4-3 deficit against City following last week's thrilling first leg in Manchester.

That was the joint-highest scoring semi-final first leg in the competition's history, along with Liverpool 5-2 Roma in 2017-18, and more drama awaits in the Spanish capital.

Villarreal face an even bigger task, meanwhile, as they trail Liverpool 2-0 through an unfortunate Pervis Estupinan own goal and a Sadio Mane strike at Anfield.

However, only once before have the Reds won both legs of a knockout stage tie against Spanish opposition in the Champions League or its former guise as the European Cup.

So will it be an all-English final in Paris on May 28, or can the LaLiga pair turn things around on home turf?

Ahead of the second legs, Stats Perform digs into some of the best Opta numbers around the two semi-final ties.

Villarreal v Liverpool

To put the size of Villarreal's task into some perspective, only once before – Liverpool versus Barcelona in 2019 – has a team overturned a two-goal first-leg deficit at this stage of the Champions League.

Villarreal are unbeaten at home in Champions League knockout ties, albeit having won just two of their seven such games. The bad news, though, is that across those seven matches, neither side has managed to score more than once on any occasion.

If they are to have any hope of advancing then Unai Emery's men need to display far more attacking impetus than was on show last week, having attempted only one shot and failed to hit the target at Anfield. The last team to fail to record a shot on target across two legs of a Champions League semi-final was Deportivo de La Coruna in 2003-04, against Jose Mourinho's Porto.

Should Liverpool see the job through, they will become only the fourth side to reach the final of the European Cup/ Champions League on 10 or more occasions after Real Madrid (16), Bayern Munich and Milan (both 11), with their current tally of nine the most of any English side.

Jurgen Klopp's side have been formidable on the road in Europe this season, scoring 15 goals and conceding five across their five away Champions League matches, all of which have ended in victory. Should they win on Tuesday, they will boast the longest 100 per cent away record by any team in a single European Cup or Champions League campaign.

After netting in the first leg it is likely that Mane will again be selected in Liverpool's star-studded front three. The Senegal international has scored 14 knockout-stage goals for the Reds in the Champions League, leaving him one short of Chelsea legend Frank Lampard's record for the most for an English club.

Real Madrid v Manchester City

The omens are good for City as they have progressed from nine of their previous 10 knockout ties in the Champions League after winning the first leg, the only exception being against Monaco at the last-16 stage in 2016-17 after squandering a 5-3 advantage to lose 6-6 on away goals.

Madrid have been eliminated from all five previous Champions League semi-finals in which they have lost the first leg, meanwhile, though they have advanced from two of their past three knockout ties when losing the first leg – against Wolfsburg in the 2015-16 quarter-finals and versus Paris Saint-Germain in this season's last 16.

Los Blancos, the competition's most successful side, have lost their past two Champions League games, though only once before have they lost three on the spin. Head coach Carlo Ancelotti, incidentally, has never lost three in a row with this his 178th match.

A draw would be enough to see City through, but they have won their last three matches against Madrid in the Champions League and could become the third side to win four in a row against them in UEFA's showpiece competition, the only previous sides to have done so being Ajax (between 1973 and 1995) and Bayern Munich (between 2000 and 2002).

City boss Pep Guardiola has had his fair share of battles with Madrid down the years, not least in the Champions League. The Catalan coach has won four matches against Los Blancos in the competition – only Ottmar Hitzfeld (seven) has won more – with half of those wins coming at the Santiago Bernabeu.

Karim Benzema has rescued Madrid a number of times in Europe this season, the Frenchman having netted nine times in the knockout stage alone. Only former team-mate Cristiano Ronaldo (10) has ever scored more in a single season, while Benzema could become the fourth player to score in both legs of the quarter-finals and semi-finals in a single season after Fernando Morientes (2003-04), Neymar (2014-15) and Edin Dzeko (2017-18). 

While Benzema has rightly received plenty of plaudits, strike partner Vinicius Junior has himself played a huge part in Madrid's charge for a record-extending 14th European Cup. The 28 open-play chances created by the Brazil international is the most of any player in the Champions League since Dusan Tadic (36) in 2018-19.

Trent Alexander-Arnold knows Liverpool must not be complacent when they start the second leg of their Champions League semi-final against Villarreal on Tuesday with a "dangerous" 2-0 lead.

Jurgen Klopp's side are strong favourites to face Manchester City or Real Madrid in the final at the Stade de France after a Pervis Estupinan own goal and Sadio Mane's strike at Anfield last week put them in command

Liverpool are the only side to reach the final after losing the first leg of a semi-final by two goals or more, overturning a 3-0 deficit with a sensational 4-0 victory over Barcelona three years ago.

The Reds are unbeaten in 12 matches and make the trip to El Madrigal on a five-game winning streak - keeping clean sheets in their past four victories.

Alexander-Arnold says they will not arrive in Spain thinking it is already job done as they prepare to face a side that dumped Juventus and Bayern Munich out.

The full-back said: "Anything can happen in football, they're a top-quality side who can beat world-class teams.

"We've seen that with Juve and Bayern. They play up to the underdog so we cannot get complacent. An old cliche, only half-time. Next goal is vital in this tie."

Liverpool boss Jurgen Klopp insists the Reds still have work to do to secure a spot in the Champions League final, and expects Villarreal to try "with all they have" in Tuesday's semi-final second leg.

The Reds are still chasing a historic quadruple after beating the Yellow Submarine 2-0 in last week's first leg at Anfield, with goals from Andrew Robertson and Sadio Mane putting Klopp's team on the brink of a third Champions League final during his seven-year tenure.

Klopp's team produced a dominant performance at Anfield to restrict Villarreal to no attempts on target, and could become the first team since Porto in 2003-04 (against Deportivo La Coruna) to not concede a single shot on target across a two-legged Champions League semi-final.

Liverpool also recorded 22 high turnovers as they suffocated Unai Emery's team, the most by a team in a Champions League knockout game this season and the most Klopp's Reds have ever produced in the competition.

However, Klopp insisted his team would have to withstand a fierce Villarreal response on Tuesday, and said Liverpool would not take anything for granted.

"No [the tie is not over], we know that. It's half-time. In the best possible way, we ignore the result from the first game," Klopp told his pre-match press conference.

"As if it was a cup tie with only one leg and it would be decided in Villarreal, we will try to win there, that's what we want to try, knowing that they will go with all they have, that was clear with all the things Unai said after the game.

"It will be another tough one, but it's fine, the Champions League semi-final should be tough. We never expected it to be easy and this will not be easy. We played a good game at home, and we had better play a good game there as well.

"The Champions League semi-final is the second-most important game you can play [after the final]. That's why whatever happened in the last few weeks is not important.

"You never know if you will reach the semi-final again, if you will ever have another chance to go to the final, you never know. We have an exceptional team here, but nothing is taken for granted, you better treat it carefully and be ready, and we will be ready."

Liverpool have won on all five of their Champions League road trips this season. Should Klopp's side win in Spain, they would have played the most away games while maintaining a 100 per cent record by any team in a single European Cup/Champions League campaign.

With the Reds on a 13-match unbeaten streak on their travels in all competitions, Klopp highlighted the importance of having extra options available in his squad compared to previous seasons.

"In general, our last periods of the season are pretty intense, because the Premier League is so difficult," Klopp added.

"It helps that we know, historically we are in the best possible shape [physically], where we don't have to push the boys through like we did in 2018, where we arrived at the final [a 3-1 loss to Real Madrid] pretty much on three wheels, with players coming back from injury and these kinds of things.

"We have to make sure we can make changes here and there and keep them all in rhythm, and to win the football games, that's what it's about."

Tuesday will also see midfielder Thiago Alcantara return to Spain after an outstanding first-leg display in which he attempted over 100 passes, and Klopp said the in-form 31-year-old would start for any team in world football.

"When Thiago is in the shape he is in now, he would play in each team in the world, and he would perform for Spain as well," he added. "He had problems when he arrived here, he got injured, and Spain obviously has a lot of options in midfield because it's an incredibly talented football team.

"But in the shape he's in at the moment he would play for each national team, and not only play in it, he would probably be the outstanding performer. 

"Every person needs to be fit and to gain rhythm and then he can show his best football. If he's in the right place physically, he will show everyone how good he is."

Villarreal boss Unai Emery says his side are excited to pit themselves against "the best team in the world" in Liverpool, as they try to overcome a two-goal deficit in the Champions League semi-finals.

The Yellow Submarine enter Tuesday's decisive second leg against Jurgen Klopp's men 2-0 down after the first meeting at Anfield last Wednesday.

To reach the final in Paris, Villarreal must become only the second team to overturn a two-goal first-leg deficit in a Champions League semi-final after Liverpool did so in 2018-19, losing 3-0 to Barcelona at Camp Nou before recording an incredible 4-0 home triumph.

But Villarreal struggled against Klopp's in-form Reds last week, attempting just one shot and failing to hit the target, and they could become the first team since 2003-04 (Deportivo La Coruna against FC Porto) to fail to record a shot on target across two legs of a Champions League semi-final tie.

Having previously described Klopp's outfit as the "best-ever" Liverpool team, Emery has now labelled them the finest side in world football, but insisted his players are relishing the prospect of competing with the Reds.

"We are very excited. The favourites were better at their stadium, but we managed to defend well," Emery said. 

"The team is psyched up to play our match and have our chances against the best team in the world. To live this moment, with all our people and against a rival, and passing this test would be excellent. I don't know if we'll be able to."

Emery is no stranger to thrilling Champions League comebacks, having been on the receiving end of one of the most famous turnarounds in history when his Paris Saint-Germain lost 6-1 at Barcelona after winning the first leg 4-0 in 2016-17's last-16.

However, the former Arsenal boss said a lot of things have changed since that classic contest, highlighting that neither team would benefit from the scrapped away goals rule on Tuesday.

"A lot of things change from the game against PSG against Barca, even things that are not in our hands. It does not favour [either team] that there is no longer the double value of away goals," he added.

"The first thing that changes is that we play at La Ceramica with our fans. We have to win, but we have to play a brutal defensive game and find our game from there."

In reaching the Champions League semi-finals for the second time in their history (the other in 2005-06), Villarreal have relied on a strong home record: Emery's men are unbeaten in seven home knockout games in the competition's history, although five of those ended level.

After Villarreal's 1-0 home win over Bayern Munich helped them dump the German champions out of the competition in the quarter-finals, defender Pau Torres says that success can serve as an inspiration for the hosts. 

"The game against Bayern can serve as an example. They were favourites and we managed to subdue them in our stadium," Torres said. "We are aware of what is at stake and what needs to be done. We have our game plan. We have seen a very strong Villarreal in important games.

"The objective is only one, no matter how it is achieved. We know that the game is long. A goal puts us in the tie.

"The coach has told us to be ourselves. We are preparing very well for the tie. We are going to be able to see a very recognisable Villarreal, with whom we all feel identified."

Jurgen Klopp insisted Liverpool still have it all to do in the second leg of their Champions League semi-final against Villarreal, despite the first leg ending in a convincing 2-0 win.

The Reds carved out their advantage during a two-minute second-half spell that saw Pervis Estupinan put through his own net and Sadio Mane get on the scoresheet.

The visitors managed just a single shot across the 90 minutes, one which failed even to test Alisson in the Reds' goal.

However, Klopp is taking nothing for granted ahead of the return leg in Spain next week, saying at a media conference after the game: "The full work is [left] to do. Nothing happened yet. 

"You play a game and it's 2-0 at half-time, you have to be completely on alert, you have to be 100 per cent in the right mood, you have the play the second half like you played the first. 

"There's nothing to defend, if you do that you give all the advantages you might have had away immediately. 

"We know we go there and it will be a tricky atmosphere for us, different to tonight. 

"Those players, you saw it tonight, they fight for the coach with all they have. What I like was that everybody could see that we fight with all we have and it's always the same. 

"If they beat us with a result that brings them to the final then they deserve it and, if not, then we deserve it. That's how the competition is."

Liverpool had taken 12 shots without scoring in an opening period that saw Villarreal frustrate - a theme of their march to this stage of the competition. 

But Klopp did not ask his team to change things up during the half-time break, instead asking for more of the same from his players.

He added: "We spoke at half-time, I thought we looked really fresh in the first half and had good legs. 

"It's intense for us to play the way we play but it's intense for the opponent to defend us in that way as well.

"It was the challenge, how it is for all human beings, when you try and you fail and try and fail [not to] think, 'Come on, it's not my day!' 

"We really had to stay positive and try and fail, try and fail, and keep trying. And that's what we did."

Liverpool left back Andrew Robertson said he and his team-mates are "enjoying" their hectic schedule as they earned a 2-0 first leg lead in their Champions League semi-final against Villarreal.

An own goal and a Sadio Mane strike, both early in the second half, was enough for Jurgen Klopp's men to secure a decent cushion ahead of next Tuesday's second leg in Spain.

Villarreal frustrated Liverpool at Anfield in the first half, but were unable to stop them from winning their ninth Champions League match of the season, the most games the Reds have ever won in a single campaign in European competition (excluding qualifiers).

Speaking to BT Sport after the win, captain Jordan Henderson praised the visitors, and said staying "positive" was key for Liverpool.

"Yeah, very organised team," Henderson said about Unai Emery's side. "We knew they'd make it difficult, but it was important that we just kept going, stay positive and we had the confidence that if we did that, kept moving the ball quickly, we'd eventually break them down, and we did that with two good goals."

It was Henderson's cross that deflected in off Pervis Estupinan to finally break the deadlock, and when told it had deflected, the England international jokingly replied: "Did it? I thought it went straight in!

"Yeah a little bit lucky, but it was good play, good build up... But, you need a little bit of luck against teams with a low block. We got that with the first and thankfully we got another one."

Liverpool had 19 shots to Villarreal's one on a dominant night for the Reds. The Yellow Submarine's one shot, which missed the target, is the joint-fewest by any side in a Champions League semi-final according to Opta since this data has been available (2003-04), along with Inter v Barcelona in 2009-10.

Robertson was also asked by BT Sport about the game, and he was keen to point out that the players are enjoying themselves, with an unprecedented quadruple of the Premier League, Champions League, FA Cup and EFL Cup still possible.

"We had quite a few chances in the first half, just trying to break them down and keep doing what we were doing," the Scotland captain said. "The first goal always kind of does that [gives you a boost], we then had a bit of momentum. The noise in here was incredible after the first goal and that kind of took us to the second one.

"We'd have liked to add maybe one more, it wasn't meant to be but a clean sheet and two goals? We can't argue with that.

"You have to [work hard], it's the semi-final of the Champions League. If you can't run about for 90 minutes in this kind of game then when will you?

"Our intensity's been really high the last couple of games, we've had a real hectic schedule and we're enjoying it. I think you seen that today.

"There's still a lot of work to do in this tie, but we're happy with our work tonight."

Also asked about not getting frustrated by a stubborn Villarreal defence, Robertson added: "That was the message from Hendo at half-time, just saying we were playing well first half, probably some of the best we've played and we didn't get a goal for it, but we kept going, kept trying to be patient and luckily with a big deflection (smiling at Henderson), we managed to get the breakthrough."

After 45 minutes of this Champions League semi-final first leg, the travelling Villarreal fans had every reason to believe they might be witnessing another miracle.

Their team had made it to half-time in the cauldron of Anfield having kept the score at 0-0, and they had also - at times - made a quadruple-chasing Liverpool look short of ideas.

As such, thoughts will no doubt have turned to the recent shock wins over Juventus and Bayern Munich, and the possibility of taking another major scalp back to Castellon.

Unfortunately, any supporter in yellow thinking along those lines had not accounted for the fact that, even among Europe's elite clubs, there are levels.

And, although Manchester City might have a strong case to be ranked alongside them, Liverpool are otherwise alone at the summit. 

It did not look much like that during an opening period that ended with the hosts having taken 12 shots, the most in a Champions League semi-final first half without scoring since such data was first collected in 2003-04.

That owed much to Villarreal's sheer refusal to offer up quality chances, with the midfield and defence working beautifully in tandem to deny all space.

The dark arts were also being deployed impressively, goalkeeper Geronimo Rulli taking as much time as he could over goal kicks, while cheap fouls were bought from frustrated opponents.

However, as he proved during Sunday's Merseyside derby win over Everton, Jurgen Klopp is never better than when given a half-time puzzle to solve.

And it looked from the very first whistle of the second period that the German had repeated the trick once again.

Suddenly, there was an extra zip to Liverpool's play, and their visitors' previously solid shape was beginning to look porous as players were dragged out against their will.

Admittedly, there was an element of fortune to the Reds' opener, Pervis Estupinan's attempted block looping over a stranded Rulli and into the back of the net.

But it had been earned through a rapid left-to-right passing exchange that opened space for Jordan Henderson to cross - the sort of move that had been missing in the first half.

From there, Liverpool smelled blood, and just two minutes later had put together another slick pattern to leave a rattled Villarreal two down. 

It was a whirlwind attacking flurry that so few teams can produce, one that will have given Klopp confidence that a third Champions League final appearance with this club awaits.

As impressive as their route to this stage of the tournament has been, Villarreal never trailed either Juventus or Bayern by more than a single goal at any stage of those ties.

And it is hard to imagine how they might close that deficit in Spain next week without opening up too much against such deadly opponents. 

Stranger things have happened, of course, but the likelihood is that a meeting with a Liverpool team eyeing the history books will prove to be a step too far for Villarreal. 

Liverpool are in the driving seat of their Champions League semi-final against Villarreal after a 2-0 win at Anfield on Wednesday.

A game that was never likely to match the excitement of Tuesday's seven-goal thriller between Manchester City and Real Madrid finally came to life in the second half as an own goal from Pervis Estupinan and a Sadio Mane strike sealed a strong first-leg advantage for the Reds.

Unai Emery's side defended resolutely for much of the game, managing to get to half-time goalless, but they were ultimately undone by some typically fast attacking from Jurgen Klopp's team in the second half.

This was Liverpool's 12th European Cup or Champions League semi-final, with no English side playing in the final four more often (level with Manchester United), and was also the first time the Reds have played in the semi-finals of the EFL Cup, FA Cup and European Cup in the same campaign, and it was that experience of the big occasion that ultimately shone through.

It was a tentative start from the home side, though Mane will have expected to do better with a header when found by a neat cross from Mohamed Salah early on with the Senegalese forward directing his effort wide.

Thiago Alcantara came as close as anyone to breaking the deadlock in the first half with a shot from almost 30 yards that crashed against the left-hand post, but the visitors did a good job of frustrating the Premier League side in the opening 45 minutes.

An electric beginning to the second half from Klopp's side finally saw them take the lead in the 53rd minute, with Jordan Henderson's cross from the right taking a fortunate deflection off the foot of Estupinan and flying past Rulli at his near post.

Another arrived just two minutes later as a good passing move ended with Salah sliding a ball through to Mane, who prodded under the goalkeeper to make it 2-0 to the Reds.

The Yellow Submarine avoided further damage but have it all to do when the two meet again in the second leg at the El Madrigal next Tuesday.

What does it mean? Liverpool show patience to break through, again

Liverpool finally overcame a determined Everton in the Merseyside derby on Sunday, it was said to be perfect preparation for Villarreal, who were always going to come to Anfield to frustrate in the first leg.

That proved to be the case as, like with the Toffees, Villarreal kept Liverpool at bay in the first half, running down the clock, blocking all attacks and keeping their net unbothered.

However, the relentless Reds again managed to force a couple of second half goals, having had 19 shots in all, facing just one solitary effort from the visitors.

Thiago once again shines in the middle

The former Barcelona and Bayern Munich midfielder has been purring in Liverpool's midfield in recent games, and he was on form again here as he helped to dissect a stubborn opposition.

Thiago completed 99 of 103 passes (96.1 per cent), enjoying a fantastic pass completion percentage in the opposition's half of 94.1 from 68 attempts. He also made more interceptions than anyone (five) and gained possession 10 times in all.

More English misery for Yellow Submarine

Emery's men put up a brave fight but eventually succumbed to a strong and determined Liverpool team, and it maintained a poor record for Villarreal in England.

Since a 2-1 victory on Merseyside against Everton in August 2005, Villarreal have not managed to win any of their last nine away games in England in all competitions (drawn three, lost six), having also tasted defeat at Manchester United in the group stages earlier this season.

What’s next?

Liverpool travel to Newcastle United on Saturday as they resume their title chase in the Premier League, while Villarreal are away to Deportivo Alaves on the same day.

The former Barcelona and Bayern Munich midfielder has been purring in Liverpool's midfield in recent games, and he was on form again here as he helped to dissect a stubborn opposition.

Jurgen Klopp has made three changes to his starting line-up for Liverpool's Champions League semi-final first leg against Villarreal.

With his side having claimed a 2-0 Merseyside derby victory over Everton last time out, the German has looked to freshen things up in defence, midfield and attack.

As has become customary during two-game weeks this season, Ibrahima Konate comes into the centre of defence to replace Joel Matip.

In the centre of the park, the captain Jordan Henderson takes the place of Naby Keita.

And up top, January signing Luis Diaz joins Sadio Mane and Mohamed Salah, with Diogo Jota dropping to the bench.

Roberto Firmino is not among the substitutes as he recovers from injury, while Curtis Jones and Kostas Tsimikas are both out with illness.

Liverpool: Alisson, Alexander-Arnold, Konate, Van Dijk, Robertson, Fabinho, Thiago, Henderson, Salah, Mane, Diaz.
