A lot's been said and written about the various ways Erik ten Hag has changed Manchester United's trajectory since his appointment last April.

His signings have made an impact; he's started to build an identity; players appear to be improving; he's getting results on the pitch.

But beyond those areas, last week's 2-2 draw with Barcelona at Camp Nou in the Europa League felt like an example of how much Ten Hag has changed the attitude of the club already.

It was a significant departure from what most fans – of United or otherwise – have come to expect from away games in European knockout ties against the biggest clubs on the continent.

Unless you support say Bayern Munich, Real Madrid, Manchester City or even Barca, there's a degree of acceptance that your team is going to spend much of the game under pressure when you face one of Europe's behemoths away from home.

This won't be lost on United fans. Even before the departure of the peerless Alex Ferguson in 2013, they would often set up with a view to halting the opponent rather than outplaying them, hence the importance of hard-working players like Park Ji-sung and Darren Fletcher.

In more recent years, Ole Gunnar Solskjaer's use of counter-attacking tactics brought mixed results. While they helped the shock 2019 Champions League elimination of Paris Saint-Germain in one of the competition's most remarkable comebacks ever, United were then comfortably seen off by Barca 4-0 on aggregate in the next round.

Jose Mourinho's United were similarly pragmatic even though they never really came up against that same standard of opposition in Europe. His only Champions League knockout tie in charge of United was against Sevilla, who knocked the Red Devils out in the round of 16.

Of course, appearing to display something of an inferiority complex away from home isn't anything new, and it's certainly not specific to European competition – United have produced many performances some might perceive to be "negative" domestically in the past 10 years or so.

Either way, the manner of their display at Camp Nou was undoubtedly a refreshing change of pace.

United were the more dangerous and more competent side for long stretches of the game. Sure, Barca had the majority of the ball, as you'd expect, but Ten Hag's men seemed to have more purpose and direction when they had it.

They managed 18 shots last week at Camp Nou. Since the start of the 2003-04 season, United have only had more attempts away from Old Trafford in a European knockout game four times – those occasions were against Schalke, LASK, Sevilla and Copenhagen.

It bears mentioning that Barca had the same amount of shots, so this wasn't about United being dominant per se, rather having the attitude, belief and mentality to go to Camp Nou and not just assume the role of the proverbial lamb to the slaughter.

When facing Barca, you accept they will have a greater share of the ball, and generally speaking that brings shots, chances. But United were able to hurt their hosts without needing to control possession.

Their shots were worth 2.2 expected goals (xG) to Barca's 1.1. In the time that this data is available (since 2013-14), United have only recorded more xG in European knockout games away from Old Trafford seven times.

Again, these opponents were sides like Granada, Anderlecht, LASK and Copenhagen. Granted, their 2.1 away to PSG in 2019 looks good on paper, but Marcus Rashford's crucial penalty obviously accounts for a massive chunk of that, and United only managed five shots on that occasion. It was smash and grab.

United's high xG at Camp Nou was partly linked to their high number of touches (32) in the Barca box. Opta data in this metric goes back as far as the 2006-07 season, and since then they have only had more touches in the opposition's area four times in European knockout games away from Old Trafford.

Those were recorded against Villarreal, Sevilla, Schalke and Copenhagen.

Of course, trying to determine which of United's opponents have been of a similar standard to this current Barca side is subjective. Similarly, it's fair to ask how good Xavi's team actually are. But you could argue that, in the time this metric has been recorded, United never had more than 19 touches in the area of opponents at the level of Barca when not at Old Trafford.

In the 2008 final against Chelsea, United had 19. Away to Real Madrid in February 2013, they had 17. At Camp Nou in April 2019, they managed 12. The only club of a comparable stature to Barca against whom the Red Devils have broken that 20-touch barrier was Milan in March 2021, but that Rossoneri side wasn't a particularly impressive team; this Barca side is currently eight points clear of the Real Madrid team that pulverised Liverpool at Anfield earlier this week.

While United were slightly disappointed not to beat Barca last week, it was still possibly their most impressive performance in Europe for well over a decade.

They were positive, purposeful and generally threatening. There was no sign of fear or intimidation.

There were few negative aspects of the performance, and so in a way it perfectly encapsulated Ten Hag's tenure so far. The Dutchman's United had already played well against – and beaten – good teams, but being the better side at Camp Nou against Barcelona is a bit different.

Four trophies are still technically up for grabs for United this term. While a quadruple is surely beyond them, another positive performance – and result – at Old Trafford on Thursday will be the biggest statement of ambition and progress yet for Ten Hag.

Inter forward Romelu Lukaku looks in better shape than before, according to his former Belgium assistant coach Thierry Henry.

Lukaku came off the bench in the 58th minute against Porto on Wednesday before netting the only goal in the Nerazzurri's Champions League last-16 first-leg win.

Inter CEO Beppe Marotta had called into question Lukaku's fitness when he told Sky Sport the forward "needs to be in perfect physical shape to deliver" and that "he is not there yet".

But Lukaku, on loan at Inter from Chelsea, provided the perfect response when he lashed home a close-range chance after his initial 86th-minute header had hit the post.

"I am so happy for Rom," Henry said on CBS Sports. "He looks fitter, he looks slimmer, he wants it.

"I think he was disappointed that he didn't start. The only answer you can give is on the field, and he did that.

"Great header. The ball goes inside, great cross, that's what you do. You come on the field and try to make an impact to make sure you can ask your coach questions – 'next time am I going to be in the starting line-up?'"

Lukaku's future remains uncertain having underwhelmed so far during his season-long loan spell with Inter, netting four times in 14 appearances.

However, his return to Chelsea last term was similarly disappointing.

"We had a discussion when he went to Chelsea, and I told him he's going to find it difficult to play at Chelsea," Henry added. "That happened to be the case, because of the way [Thomas] Tuchel liked to play.

"Pressing, you're the nine, I'm the nine, I'm the winger, you're the winger, you have to change. Rom likes to stay where he is. Feed him, play him in early, and he'll try to bully you.

"He was a different type of nine to what Tuchel wanted. Is he going to fit what [Graham] Potter's trying to do? They're struggling enough.

"And what does he want to do? I don't think he wants to go back. That's the main thing. He wants to stay at Inter."

Marco Rose suggested Josko Gvardiol will still be playing for RB Leipzig next season as the coach attempts to stave off Premier League interest in the centre-back.

Reported Chelsea target Gvardiol salvaged a 1-1 draw for Leipzig in Wednesday's Champions League last-16 clash with Manchester City at Red Bull Arena.

The Croatia defender also previously named Liverpool as his "dream" destination after impressing at the World Cup alongside former Red Dejan Lovren.

But Rose insisted the 21-year-old will remain with Leipzig, despite a credible performance in a potential Premier League audition against Pep Guardiola's side.

"Josko Gvardiol will be an RB Leipzig player next season as well," he told TV 2 Sport after Leipzig's first-leg clash with City.

"I am the coach and I am asking for that. He is happy here. He said he wants to play in the Premier League, but he didn't say when."

Rose joked Gvardiol "should play basketball" after his towering headed equaliser in the 70th minute, though he was left unimpressed with Leipzig's first-half showing.

"We should start to play and fight. It was a really difficult first half, 26 per cent possession isn't enough," Rose told BT Sport.

"We were too passive in every situation. They moved the ball and they moved us. We had no power."

However, another impressive outing for Gvardiol against one of Europe's elite secured a share of the spoils and left it all to play for in the March 14 return leg at Etihad Stadium.

"The second half was totally different. Better late than never."

Simone Inzaghi could not hide his frustration at Inter only building a 1-0 lead to take to Porto for the second leg of their Champions League last-16 tie.

Inter were slender victors in San Siro on Wednesday thanks to Romelu Lukaku's late winner, the Belgian scoring for the second game running after not previously netting for the club since before the World Cup.

Lukaku's goal came as a huge relief to Inter, who otherwise looked destined to be held to a 0-0 draw that would have arguably made Porto favourites to progress to the quarter-finals.

Inter had chances to open the scoring before Lukaku's strike, with Lautaro Martinez and Alessandro Bastoni spurning great opportunities in the first half.

There was also an opportunity just after Lukaku's second-half introduction where he almost teed up strike partner Martinez, but the Argentinian could not reach the low cross.

Inzaghi generally appeared satisfied, but his frustration was also obvious.

"We played an excellent game against a physical and technical opponent, an excellent team," he told Prime Video. "There is regret because we had situations in the first half.

"In the second half the changes helped us. We wanted something more, but we are satisfied because we played a great match.

"[Marcelo] Brozovic and Lukaku entered very well, [Denzel] Dumfries and [Robin] Gosens too. I need everyone because it's not easy to play matches like this.

"In the first half we had to be quicker to pass the ball, we had to build better and quicker. Porto attacked us ferociously, but we had to pick up the pace and we deserved the lead straight away in the first half."

Edin Dzeko was the one to make way for Lukaku, and the Bosnian forward reacted angrily to being withdrawn.

Inzaghi refused to blow the situation out of proportion, however.

"I was expecting this question," Inzaghi told reporters with a laugh. "I too got angry when I went off the pitch in these matches, but it was enough for me to see him jump up after Lukaku's goal.

"These are things that happen on the pitch for the adrenaline of these evenings, let's not forget that in these 18 months with Inter, Dzeko has done a lot."

The two sides will tussle again on March 14 at the Dragao, and while Inzaghi acknowledged Inter do have the edge, he was keen to impress on his players that they have a long way to go yet.

"Yes, you said it correctly, we have a slight advantage, which we will try to make count," he continued.

"We faced a strong, physical team, who are used to playing this round in very important competitions.

"The first half was 0-0, then we stretched out a bit for the desire to bring it home. We risked on that one occasion where [Milan] Skriniar and [Andre] Onana were very good [to deny Porto a goal], then we closed it out well with the four substitutions that came in at their best.

"Applause to the team, but it's only the first leg."

Pep Guardiola hit out at suggestions Manchester City were expected to comfortably defeat RB Leipzig after a frustrating 1-1 draw in their Champions League last-16 clash.

Riyad Mahrez fired City into a 27th-minute lead on Wednesday at the Red Bull Arena, with City utterly dominant in the first period of the first leg in Germany.

But Guardiola's visitors did not capitalise on their control as Leipzig fought back after the interval and Josko Gvardiol secured a share of the spoils ahead of the March 14 return clash at Etihad Stadium.

Marco Rose's side are fifth in Bundesliga and had not scored a goal in three previous Champions League knockout clashes, though Guardiola refused claims a comfortable victory at Leipzig was always on the cards.

The City manager told BT Sport: "People expect we are going to win 5-0, that's not a reality. It is past the group stage in a very competitive competition and many important teams around.

"It is difficult, we knew this, our fourth game in 10 days, the away games, the travels and the people expect [wins]…

"I know we are a good team, and we continue to do good things. But people expect we come here and win 4 or 5-0, we are not able to do this."

The opening 45 minutes were in stark contrast for what was to follow, with City boasting 74 per cent possession and only conceding one shot on target in the first half – a timid Timo Werner effort at Ederson.

Guardiola's side managed just a 49.2 per cent share of the ball in the second half, facing six shots, as substitute Benjamin Henrichs spurned a pair of glorious opportunities.

Former Bayern Munich and Barcelona boss Guardiola insisted he was "happy" with the entire performance, however.

"They make a step forward, they pressed everyone high up, more problems in the build-up," he said when asked about the second half.

"After the goal we conceded, we came back – we made a good last 15, 20 minutes. We had good chances, both sides in both halves, and now we go back to Manchester to decide it."

Pressed on the drop in performance levels, a somewhat irked Guardiola added: "I'm happy for the whole game, not just the first half. What do you expect? We play a friendly game here?"

Despite Leipzig growing in confidence as the final whistle drew closer, Guardiola opted to make no substitutions throughout.

That was the first instance of no changes from a team during a Champions League match since Jose Mourinho did so with Manchester United against Juventus in October 2018.

But Guardiola remained confident with his decision, albeit admitting he considered introducing Phil Foden.

"I saw the team good, especially in the middle," he continued. "I thought about Phil, but at the end I decided to continue with what I had.

"Bernardo [Silva] was giving a lot of control and I thought we could win it."

Romelu Lukaku was decisive off the bench with a late winner as Inter scraped a 1-0 victory over Porto in the first leg of their Champions League last-16 tie at San Siro.

Simone Inzaghi's men appeared to be heading for a disappointing goalless draw that would have arguably put Porto in the driving seat for the second leg, but Lukaku came to Inter's rescue.

The Nerazzurri had been wasteful during a tense first half, with Lautaro Martinez spurning a great opportunity and Alessandro Bastoni forcing Diogo Costa into a brilliant save.

They then struggled to make the most of their dominance in the second half, but shortly after Porto midfielder Otavio was sent off, Lukaku turned home to score for the second time in less than a week.

Manchester City failed to capitalise on their early dominance as Josko Gvardiol salvaged a 1-1 home draw for RB Leipzig in the Champions League last 16.

Pep Guardiola's side piled the pressure on in the first half of the first leg at Red Bull Arena and Riyad Mahrez fired City into a deserved 27th-minute lead on Wednesday.

But City's control wavered in the second period as substitute Benjamin Henrichs missed two great chances before Gvardiol earned a share of the spoils with a thumping header after 70 minutes.

Guardiola will be left rueing what could have been after an impressive display in the opening half, leaving it all to play for in the March 14 return leg at Etihad Stadium.

City monopolised possession in the opening stages but created little without absent chief creator Kevin De Bruyne, who missed the Germany trip through illness.

That pressure soon told, though, as Ilkay Gundogan punished a wayward Xaver Schlager pass to find Mahrez, who arrowed into the bottom-right corner from outside the area.

Rodri headed narrowly wide and Jack Grealish blazed over as City threatened to further their advantage, with Leipzig fortunate to go in at half-time just a goal down.

Henrichs should have levelled after the interval, first wastefully heading over before dragging a glorious opportunity wide to the right of Ederson, who denied a fizzing Dominik Szoboszlai strike soon after.

The much-improved Leipzig grabbed a deserved equaliser from Marcel Halstenberg's resulting corner as Gvardiol powered home, with City's appeals for a foul falling on deaf ears.

Janis Blaswich then denied a whipped Gundogan effort destined for the bottom-right corner, ensuring it remains all to play for in the return leg in England.

Neymar has suffered ankle ligament damage and could be a doubt for Paris Saint-Germain's Champions League meeting with Bayern Munich.

The 31-year-old was taken off on a stretcher during PSG's thrilling 4-3 win over Lille on Sunday.

Having teed up Kylian Mbappe's opener and then scored PSG's second goal, Neymar went over on his right ankle in a challenge with Benjamin Andre early in the second half.

PSG subsequently confirmed Neymar had not suffered a fracture but instead a sprain.

On Tuesday, they announced further scans had indicated ligament damage, and Neymar must now wait until next week for a firmer timescale to be put on his recovery.

According to the United Kingdom's National Health Service, the standard recovery time for such an injury is between six and eight weeks, which would rule him out of the second leg of PSG's last-16 tie with Bayern on March 8.

PSG, who face Marseille in Ligue 1 on Sunday, head to Munich trailing 1-0 from the first leg.

Virgil van Dijk acknowledged Liverpool were at fault for their mistakes in their Champions League loss to Real Madrid but argued they cannot expect to perform like "robots".

Liverpool blew a two-goal lead at Anfield, slumping to a 5-2 loss in the first leg of their last-16 tie against the holders.

Amid a difficult season for Jurgen Klopp's side, their collapse against Madrid made for a chastening rematch of last year's final, which finished 1-0 to Los Blancos in Paris.

Van Dijk did not dispute another off-colour performance yet the centre-back stressed errors are to be expected when players are only human.

"[Across] the whole of the Champions League, there are quality players all over teams," he told reporters. "They can punish you, and can punish the mistakes that you make.

"That's what they did in the second half, and it is pretty clear to see. [There were] mistakes that we shouldn't make, but it happens in football.

"We're not robots, sometimes mistakes happen. That is the case. The only thing we can do is learn from it and focus on the next one to ensure it doesn't happen [again]."

After goals from Darwin Nunez and Mohamed Salah had given them a two-goal cushion inside the opening 15 minutes, Liverpool seemed on course for a memorable Anfield triumph.

Yet their defensive frailties came to the fore as Vinicius Junior curled in a supreme finish before pouncing on Alisson's mistake to restore parity.

Eder Militao put Madrid ahead early in the second half before Karim Benzema's double left the hosts with a mountain to climb in the return leg next month.

Klopp was less than impressed with cheap concessions, but did feel his side's first-half performance was among the best they have delivered this campaign.

"We gave all five goals away," he said in his post-match press conference. 

"All five. We could have done better there [but] in our situation where we are, it is really important we that see positive steps.

"I think the first half, aside from the two goals we conceded, was the best we've played [across] the whole season.

"The second half obviously was the game Real Madrid wanted to play, and that's how we came to the result."

The lasting image of Josko Gvardiol's campaign in Qatar isn't one that his performances warranted.

Gvardiol enjoyed a fine World Cup as Croatia reached the semi-finals, but like so many defenders before him, the 21-year-old came unstuck against Lionel Messi.

If one were to fall on British footballing parlance to describe how Messi turned Gvardiol one way, then the other, and then back again en route to teeing up Argentina's third goal in a 3-0 win, then the term "sent to the shops" would probably be fitting.

Gvardiol might be stronger, more athletic and 14 years younger than Messi, but the latter is considered by many to be the best player of all time, and his nimble feet and speed of thought left Croatia's star defender clutching at thin air on that night at Lusail Stadium.

Yet that incident shouldn't mar what was a stellar tournament for Gvardiol, who will be tasked with keeping more superstars on a tight leash when RB Leipzig host Manchester City in the Champions League on Wednesday.

Gvardiol has been heavily linked with Chelsea in the past. It remains to be seen whether the big-spending Blues will be back in for the centre-back, or will it be City – who might well be in need of a versatile, left-footed defender in the wake of Joao Cancelo's seemingly impending permanent departure and with speculation over Aymeric Laporte's future.

Real Madrid have also been mooted as having an interest, but Gvardiol has his eyes on a move to England.

"I want to play in the Premier League," he told The Times, while reflecting on his decision to join Leipzig over Leeds United in 2020. "Chelsea were really interested, but Leipzig told me they didn't want to sell me. My dream is to get to the Premier League one day."

This meeting with City could just be the audition Gvardiol needs to pass for that dream to come true.

The crown jewel of Croatia's next generation

Luka Modric might have been the driving force in Croatia's semi-final charge, and ultimate third-place finish, but Gvardiol was arguably just as integral.

On the ball, Gvardiol was superb, and that's something that will certainly be of interest to potential suitors. The composure and passing ability he has shown at Leipzig transitioned onto the international stage and by the end of the competition he had made 21 progressive passes – only 14 players managed more.

Gvardiol topped the charts for carry distance and ball carries, with his stature and pace making him difficult to stop as he moved out of defence while in possession, giving Croatia a different dimension when attacking.

He made 202 carries for a distance of 1,985.3 metres, an average of 28.8 carries per game and 283.6 metres per match, with Gvardiol playing every minute of Croatia's campaign.

Gvardiol completed 24 long balls in Qatar, behind only four other defenders, while only Argentina's Nicolas Otamendi attempted and completed more passes.

His only goal at the tournament came in Croatia's win over Morocco in the third-place play-off, though it was not just on the ball that Gvardiol impressed.

The youngster made more clearances (37) than any other player and won possession back 48 times, the most of any defender.

Leipzig the ideal fit

"Here in Germany I feel good, I'm in a good club and I play almost all matches," Gvardiol said in his interview with The Times.

Since he made the switch from Dinamo Zagreb, Gvardiol has made 48 appearances for Leipzig, starting 42 times. He has scored two goals, both coming this season and at home, and teed up a further two as well. For such a young player, Gvardiol boasts an impressive disciplinary record, picking up just eight bookings.

Leipzig have won 25 of the 48 matches he has played in, losing 12 and drawing the other 11. 

This season, Gvardiol, slotting in alongside Willi Orban, has played a part in keeping five clean sheets, and ranks second out of Leipzig's defenders behind the Hungary international in that regard.

Of his fellow Leipzig defenders, Orban is the only one to have won possession back on more occasions (173) than Gvardiol (132), with 65 of those regains coming in the defensive third.

When assessing Gvardiol's statistics per 90 minutes, he betters his centre-back partner for interceptions (1.44 to 1.39) and possession won (6.6 to 5.9), while he has a defensive-unit high 77.4 successful passes.

Orban is more of a stopper, evidenced by his 4.1 clearances, 2.5 headed clearances, 1.6 tackles, 8.6 duels and 4.6 aerial duels per 90 minutes. Gvardiol is an ideal folly with his progressive, accurate passing, though he averages only one tackle per game, while his tackle success rate of 57.1 is the joint-lowest out of Leipzig's defensive options.

Breaking the lines is a key facet of Gvardiol's play, and though Orban betters his total number of carries in the Bundesliga this season, the Croatian has taken the ball further than any of his team-mates in the competition (3,334 metres), averaging 10.23 metres each time.

Leipzig have provided Gvardiol with an ideal environment in which to thrive and develop, though he is about to face a stern test in the form of Europe's deadliest striker.

Much ado about Erling?

Erling Haaland has scored 32 goals in 31 appearances since joining City from Leipzig's Bundesliga rivals Borussia Dortmund last year.

Such has been his rich form, that one or two games without a goal for Haaland results in speculation as to whether City actually know how to get the very best out of their striker, or if he is suited to Pep Guardiola's approach.

This will not be the first time Gvardiol has gone up against the Norwegian, having done so previously in April last year.

On that occasion, Gvardiol formed part of a three-man defence that helped Leipzig to a stunning 4-1 win at Signal Iduna Park, with Haaland kept quiet.

Haaland had 27 touches, but only four of those came in Leipzig's area, while his only shot was off target (he was only limited to zero shots in a game on one occasion in the Bundesliga last term) and he finished with an expected goals of 0.15. 

Leipzig will have more than just Haaland to worry about on Wednesday, of course. Gvardiol will likely have Kevin De Bruyne and Riyad Mahrez bearing down on him at some stage, but an elite performance against this calibre of opposition might just get him that dream move to England.

It could even be with City, and the two legs of this last-16 tie could go a long way to convincing Guardiola.

Erling Haaland should be licking his lips at the prospect of facing RB Leipzig when Manchester City continue their quest to lift the Champions League for the first time on Wednesday.

City travel to Leipzig for the first leg of their round of 16 tie smarting from slipping off the top of the Premier League table with a 1-1 draw at Nottingham Forest on Saturday.

The combination of both City and striker Haaland's great record against the Bundesliga side would suggest they ought to secure a place in the quarter-finals of Europe's premier club competition.

Inter have home advantage when they face Porto in the other round of 16 first-leg clash on Wednesday and the Serie A side boast an impressive home record against Portuguese clubs.

Stats Perform pick out the standout Opta data to preview the matches at Red Bull Arena and San Siro.

RB Leipzig v Manchester City

Former Borussia Dortmund striker Haaland will return to Germany to come up against a club that he has fond memories of facing.

The Norway international's finishing let him down at the City Ground at the weekend, but Leipzig know all about the threat he poses.

Haaland has found the back of the net six times in four games against Leipzig, scoring three braces against them during his time with Dortmund.

City have only lost one of their previous 17 matches against German sides in the Champions League (W14 D2), with the Premier League champions scoring an average of 2.6 goals per game in those fixtures. Their only defeat came away to Leipzig in last season’s group stage, when Pep Guardiola's side had already qualified for the last 16.

Leipzig will fancy their chances of causing an upset, though, as they have won each of their past four Champions League matches – which is their best run in the competition.

Only Julian Nagelsmann in the 2019-20 season – when they reached the semi-final – has won more matches in a Champions League campaign (six) in charge of RB Leipzig than Marco Rose's four this term.

Inter v Porto

Porto travel to Milan on a magnificent unbeaten run that stretches back to October 21.

Sergio Conceicao's tally of 30 Champions League wins is more than any other Porto boss has achieved and his 50 per cent win rate in the competition is second only to Julen Lopetegui's 56 per cent during his tenure.

This will be the 10th time Inter have hosted a Portuguese side in European competition. They are unbeaten in the previous nine – eight of which have been victories. The only side to avoid defeat were Boavista, in a goalless UEFA Cup draw back in 1991.

Edin Dzeko has been directly involved in four goals in six Champions League games this season – scoring three and proving one assist. That is more than any other Inter player.

Porto have won four successive Champions League games and will be aiming to equal their longest winning run in the competition – a run of five between October and December 2018, which was also set under Conceicao.

Mehdi Taremi has been directly involved in seven goals in five games for Porto in the Champions League this term – with five goals and two assists. That is the most by a player in a single campaign for the club since Moussa Marega's eight in the 2018-19 campaign.

Liverpool manager Jurgen Klopp believes Carlo Ancelotti thinks their Champions League last-16 tie is over after Real Madrid trounced the Reds 5-2 at Anfield in Tuesday's first leg.

The Reds blew an early two-goal lead after Darwin Nunez and Mohamed Salah's early strikes to suffer the heavy defeat, which leaves them with a mountain to climb in the second leg in Madrid on March 15.

The defeat was the first time the Reds have conceded four or more goals at home in a European game.

Ancelotti insisted the tie is still live after the game despite the deficit, while Klopp remained hopeful, but conceded it was going to be tough to turn it around.

"I think Carlo thinks the tie is over – and I think it as well in the moment," Klopp told reporters. "But in three weeks... the closer you get to the game the bigger our chances become and the less likely it is the tie is over.

"Tonight, with the 5-2, they are pretty good in counter-attacking and we have to score three goals there and take some risk, so that could be a bit tricky.

"We go there, I can say it now already and try to win the game. If that is possible or not, I don't know now but that's what we will try and from there we will see."

Liverpool became the first team in Champions League history to lose by a three-goal margin after being 2-0 up.

Klopp acknowledged Eder Militao's free header from a Luka Modric set-piece straight after half-time for 3-2 shifted the momentum.

"I really thought the 3-2 had a massive impact," he said. "The 2-1 and the 2-2 not so much… my personal feeling was, 'first goal, OK, bad defending but well done as well, the second was slapstick but get over it'.

"Then the third goal directly after half-time, we didn't deal particularly well with that. We don't want to concede goals but I think if we just think about the first half, everybody's impression was, 'Wow, that was a really good first half' even when we conceded two.

"I really thought our people saw it exactly like that, they were outstanding tonight in a difficult game. The first half it was not too difficult to be positive but in the second half when it was difficult to stay positive, they were positive and I am thankful for that."

Defender Joe Gomez was replaced in the 73rd minute with an apparent injury concern, although Klopp had no clear update on his status.

"He showed a little bit of a sign but then we just made a decision," Klopp said. "Now we will see and he will get checked tomorrow."

Real Madrid coach Carlo Ancelotti lauded Vinicius Junior as the "most decisive player in world football" after inspiring Tuesday's 5-2 Champions League win over Liverpool.

Madrid found themselves trailing 2-0 early on thanks to goals from Darwin Nunez and Mohamed Salah, the latter coming after a calamitous Thibaut Courtois error.

But Vinicius scored twice before half-time to level the score – his first a wonderful finish into the bottom-right corner, the second a fortuitous goal that involved him blocking Alisson's clearance into the net.

He then won the free-kick that yielded Madrid's third goal just after the break and got the assist when Karim Benzema made it 5-2.

Seven players from Europe's top five leagues have more than Vinicius' 27 goal involvements across all competitions this term, though Ancelotti would seemingly not swap any of them for the Brazilian.

"Today, in my personal opinion, he is the most decisive player in world football," Ancelotti told reporters of Vinicius, who became the youngest (22 years and 224 days old) away player to score twice against Liverpool at Anfield in major European competition since Johan Cruyff in December 1966 (19y 233d).

"He doesn't stop. He dribbles, assists, scores. Now he is the most decisive. Hopefully he can continue like this."

The match was a far cry from the two teams' previous meeting in last season's Champions League final, which Liverpool dominated before losing 1-0.

It was put to Ancelotti that Liverpool had changed a lot – regressed, even – since that game in Paris, but he was not so sure and looked to impress on his players that the tie is not over yet ahead of the return leg on March 15.

"I only know that we have taken advantage in these 90 minutes and we have to manage the 90 in Madrid well," Ancelotti added.

"Liverpool are a very competitive team, who have created many problems for us. Unfortunately, the tie has not ended.

"They are still a great team in my opinion. They play with intensity and a very high pace, it is difficult to see teams like that in Europe.

"They haven't changed, but we proposed a game plan that was different from the one in the final. Then we played with a low block, and this time our plan was very different."

Jordan Henderson knows Liverpool were their own worst enemies in a stunning 5-2 Champions League defeat to Real Madrid at Anfield.

The Reds made a dream start to the first leg of the round-of-16 tie on Tuesday, opening up a two-goal lead after only 14 minutes courtesy of a sublime Darwin Nunez flick and a Thibaut Courtois howler that enabled Mohamed Salah to become the club's record European scorer with 42.

That was as good as it got for Liverpool on Merseyside, as Vinicius Junior pulled one back with a sumptuous finish before Alisson's terrible attempted pass struck the Brazil winger and looped into the net.

An unmarked Eder Militao capitalised on abysmal Reds defending to head the holders in front early in the second and Karim Benzema's double put them in complete command.

Madrid beat Liverpool in the final last year and Carlo Ancelotti's side should seal their place in the last eight in the second leg at the Santiago Bernabeu on March 15.

Reds captain Henderson feels the Premier League side only have themselves to blame after they conceded five goals at home for first time in Europe, with Madrid becoming the first team to win by a three-goal margin after being two down in the Champions League.

The midfielder told BT Sport: "It's Very difficult. For large parts of the first half we performed well and were unlucky to be level at half-time. We made too many mistakes. Real Madrid punished us every time tonight.

"A lot was [due to] their quality. We didn't help ourselves for sure. We didn't defend it [Militao's goal] well enough. The game went away from us at that point.

"The last two games we kept clean sheets. it's difficult to come here and speak. Yes, they have a lot of quality. When you're not 100 per cent defending they punish you. We caused ourselves problems at times. It's a tough one to take in the end.

"We still played a good first half. We were on top and created some good chances. There was a good chance at 2-0, a scuffle on the line. If that goes in it's a big moment.

"The second goal obviously is a mistake. The third we'll be disappointed with. That's when the game went away from us."

Henderson says Liverpool can ill afford to feel sorry for themselves as they look to climb from eighth in the Premier League and sneak a Champions League spot for next season, with their chances of qualifying as European champions looking so slim.

"It's [the second leg] still a few weeks away," he added. "We have to move on quickly. We have Premier League games before then, so we have to concentrate on that, and cross this bridge when we come to it."

Jurgen Klopp rued Liverpool's inability to maintain their momentum as they suffered a 5-2 comeback defeat to Real Madrid after a breathtaking start.

Liverpool raced into a 2-0 lead at Anfield on Tuesday, seemingly putting themselves in a great position in their Champions League last-16 tie.

But Madrid had wiped out their lead by half-time and ultimately romped home to a stunning victory as they became the first team to put five past the Reds at Anfield in Europe.

Darwin Nunez and Mohamed Salah got the Liverpool goals before Vinicius Junior and Karim Benzema scored braces either side of Eder Militao's header – both teams' second goals came from glaring goalkeeping errors.

Klopp was noticeably dejected at full-time, but he did not appear especially angry.

Instead, he was keen to highlight how he felt Liverpool looked like their old selves again during the first half before being knocked off course.

"The beginning was outstanding," he told BT Sport. "It was us in a nutshell. It was perfect, exactly how we wanted to play, causing problems all over the place. A super intense start, 2-0 up. The whole first half was good beside the goals.

"After the first goal we became slightly passive higher up the pitch, we weren't chasing them, and we had to chase them because this is a team that when you get passive, you get punished. The second goal is slapstick. It shouldn't happen, can't happen, 2-2.

"The first situation pretty much [after half-time] they played a long ball to Vinicius. I'm not sure if it's a foul, but in the end [the referee] whistles it, and how we defend that is not OK. Then 3-2 and that doesn't help against a team who are outstandingly good on the counter-attack.

"We couldn't get back on track anymore. You need to play like the first half for the full 95 minutes. That's possible, but you need momentum back. After the 3-2 goal, it was exactly the opposite.

"They became more confident and scored great goals. One was deflected, I think. That's how it is. It's a strange one. We lost 5-2, we know that too, but there's a lot from me to take from it as well."

Liverpool go to Madrid for the second leg on March 15, knowing they require something akin to a miracle if they are to eliminate the reigning champions and secure their unlikely passage to the quarter-finals.

First, though, the Reds go to Crystal Palace on Saturday hoping to make it three wins in a row in the Premier League. Victory at Selhurst Park will move them to within three points of the top four.
