Liverpool manager Jurgen Klopp evoked memories of their famous win over Barcelona in 2019 during their “thunderstorm” second-half comeback to beat Luton 4-1.

Trailing to Chiedozie Ogbene’s 12th-minute header, Klopp’s side were a different prospect after the break with Virgil van Dijk, Cody Gakpo, Luis Diaz and Harvey Elliott bringing up 100 goals for the season.

While it by no means matched the magnitude of their Champions League semi-final comeback after losing the first leg 3-0 to the Catalan giants, it was significant in terms of the title race – re-establishing a four-point lead over Manchester City – and the invigorating atmosphere which the team will undoubtedly have to lean on during the run-in.

“Tonight is one of those nights where it is difficult to stop talking. I am so happy,” said Klopp, who was without 11 first-team players including forwards Mohamed Salah and Darwin Nunez who remain doubtful for Sunday’s Carabao Cup final against Chelsea.

“We had to ignore the fact we were 1-0 down and use the things that are good and improve the counter-press. The second half was a thunderstorm. Wow.

“I will mention this game from now quite a few times. I promised my team a few months ago that I would never mention or use the Barcelona game as an example and I used it again today so I broke my promise.

“Just because before the game, it was kind of similar. Many players missing, stuff like this. The team that time ignored the fact who is missing and I want us to ignore the fact who is missing.

“That is difficult because the public got the whole knowledge of who is missing only tonight. It’s like… I needed a few minutes to process it when I got all the news.

“But from that moment on, when you know how you can deal with it and sort it for this game, it feels really good. That is what I wanted the boys to show.

“This is an example tonight. This is their Barcelona, now against Luton. A difficult situation, plenty of reasons to give up in moments: not tonight and I saw only a super group fighting.

“If you don’t limit yourself with bad thoughts, you can fly. And that’s what the boys did.”

Luton head coach Rob Edwards, whose side were impressive in the first half, admitted scoring so early just made their task harder.

“We just made them angry,” he said. “Overall it was a really good first half. Second half I thought we saw Anfield, saw Liverpool, saw their full-throttle football. Their counter-pressing football was amazing.

“In the end, it was a great learning curve for us to see what the best looks like. I know they had some players missing, but their second-half performance was like the best out there.

“I thought we were very, very good. They were better.”

Mikel Arteta bemoaned a lack of aggression from his Arsenal side in the Champions League defeat at Porto but said it would be “cruel” to judge their return to the knockout stages on the last-gasp goal that settled the contest.

The Gunners’ hopes of reaching the quarter-finals for the first time in 14 years suffered a blow as Galeno’s fine late strike saw Porto win 1-0 in the last 16 first-leg tie.

With the second leg at the Emirates Stadium on March 12, Arteta now knows his side must win on home soil to reach the business end of the Champions League on their long-awaited return.

Arsenal, more than anyone, know there are no easy games at this stage of Europe’s elite club competition – having fallen at this hurdle seven years in a row under Arsene Wenger.

This is their first time back at this level since the last of those in 2017 and it proved much more challenging than the recent Premier League thrashings of West Ham and Burnley for a team inexperienced on these occasions – Kai Havertz the only player from the starting XI with any previous appearances in the Champions League knockout phases.

The vistiors failing to register a shot on target on a tough night at the Estadio do Dragao with Porto more than a match for the Gunners, frustrating the visitors for much of the evening and ultimately capitalising on some lapse defending to secure a late victory.

“Obviously I am very disappointed the way we gave the game away at the end,” Arteta said.

“Not managing that situation well enough. You get punished in the Champions League. If you cannot win it, you don’t lose it.

“We really dominated the game but we lacked purpose, especially in the first half. You need to have much more aggression, you need to break lines, to play forward and generate much more threat on that backline.

“We will learn from it. Now it is clear, it is half-time. If you want to be in the quarter-finals you have to beat your opponent and that will be the purpose and the plan.”

Asked if his team were naive to fall to defeat in such a way, Arteta added: “Well it’s only the last ball, so if in 94 minutes they haven’t had any naivety other than that one.

“I think it’s a bit cruel to judge it. But it’s true that it has had a big impact on the result. A lot of other things they did for the first time here were very good. When you give the ball away three times in that area – you cannot do it.”

Arteta also criticised the performance of referee Serdar Gozubuyuk, who awarded 36 fouls – the most in a Champions League game this season – and often spent time ahead of set-pieces speaking to players in the box.

“From set-pieces as well every time we touched somebody it seemed to be a foul before we even kicked the ball. But we will learn and do better,” added the Spaniard.

Porto, captained by 40-year-old Pepe, appeared much more streetwise to the task at hand, leaving head coach Sergio Conceicao happy with the result.

He said: “The team understood perfectly the spaces they had to step into to condition our opponents and also what we had to do up front to hurt them.

“It was a good game, a Champions League game. Our opponents had more of the ball, but Porto were always more dangerous.”

Victor Osimhen rescued Napoli a 1-1 home draw against Barcelona in the first leg of their Champions League last-16 tie in his first appearance for the Italian club since December.

Osimhen, who had served a ban in Napoli’s previous game after returning from Africa Cup of Nations duty for runners-up Nigeria, stole clear in the penalty area with 15 minutes remaining to fire home an equaliser.

Barcelona had taken a deserved lead on the hour-mark through Robert Lewandowski’s 93rd Champions League goal.

It was Napoli’s first game since they sacked head coach Walter Mazzarri after three months in charge and replaced him with Slovakian Francesco Calzona.

Porto winger Galeno’s stunning stoppage-time winner clinched his side a 1-0 win against Arsenal in the first leg of their tie.

Arsenal looked set to return to London all-square after a cagey tactical battle at Estadio do Dragao, but Brazilian Galeno crashed home a shot from outside the box in the fourth minute of added time.

The Gunners, bidding to reach the tournament’s last eight for the first time since 2010, created few chances, while Galeno struck a post with a close-range effort in the first half.

Kai Havertz had Arsenal’s best two chances late in the first half, firing off target from six yards before heading Bukayo Saka’s corner just wide.

The two sides will meet in the return leg at the Emirates Stadium on March 12.

Arsenal’s hopes of reaching the Champions League quarter-finals for the first time in 14 years suffered a blow as they slipped to a last-gasp defeat in the first leg of their last 16 clash in Porto.

On the eve of the tie, Mikel Arteta challenged his players to prove they belong on this stage but they laboured for large parts of the game and failed to register a shot on target throughout a largely drab affair, losing 1-0 at the death courtesy of a stunning Galeno strike.

With the second leg at the Emirates Stadium on March 12, Arteta now knows his side must win on home soil to reach the business end of the Champions League on their long-awaited return.

Arsenal, more than anyone, know there are no easy games at this stage of Europe’s elite club competition – having fallen at this hurdle seven years in a row under Arsene Wenger.

This is their first time back at this level since the last of those in 2017 and it proved much more challenging than the recent Premier League thrashings of West Ham and Burnley.

Porto currently sit third in the Primeira Liga, off the pace of their big rivals Benfica and Sporting Lisbon, but they were a match for the Gunners, frustrating the visitors for much of the evening.

Declan Rice was walking a tightrope for almost the entirety of the contest after he was booked for a late challenge on Galeno with just 67 seconds on the clock.

Arsenal were not at their recent, slick best and were very fortunate not to fall behind just before the midway point of the first half as Galeno wasted two great chances in quick succession.

After a cross dropped to him in the box, with the Brazilian fizzing a shot off the far post and then somehow turned the rebound wide for six yards – the home fans flummoxed as they celebrated along with the music that greets a goal for the hosts inside the Estadio do Dragao.

The let-off failed to rouse Arsenal from something of a slumber, but they did finally have their first shot on the evening after 33 minutes and should have taken the lead themselves soon after only for William Saliba to head a Bukayo Saka corner wide.

Porto were still the more likely to open the scoring, though, as Evanilson drew a low save out of David Raya with what proved to be the only shot on target from either side until the late winner.

Kai Havertz, who scored the winning goal in a Champions League final in this stadium for Chelsea, was next to miss the target with a header from a Saka corner.

Set-pieces certainly seemed Arsenal’s best way to goal and Leandro Trossard will feel he should have done better as he peeled off to the back post from a corner early in the second half, only to fire Rice’s centre harmlessly over.

There were no other opportunities of note until the dying embers, when Galeno collected the ball and brilliantly bent a finish over the out-stretched Raya as the whole Porto bench burst onto the pitch in celebration.

For Arsenal, they return to their Premier League title challenge knowing their backs are against the wall in their quest to progress in Europe.

Victor Osimhen snatched an unlikely 1-1 draw for Napoli in the first leg of their Champions League last-16 tie against Barcelona.

The Nigeria striker cancelled out a trademark Robert Lewandowski strike as a low-quality tie ended all square.

The champions of Italy met the champions of Spain in what should have been the glamour tie of the round at Napoli’s Stadio Diego Armando Maradona.

The Argentinian’s name is synonymous with glory days at both clubs but now both are struggling to recapture last season’s title-winning successes.

Napoli, a lowly ninth in Serie A, sacked Walter Mazzarri on Monday with Francesco Calzona replacing him as their third manager of the season.

The Slovakia coach, appointed on an interim basis, had just 48 hours to try to inject some life into their dismal campaign.

Meanwhile, Barca boss Xavi – whose side lie eight points behind rivals Real Madrid in La Liga – announced last month he would be leaving at the end of the campaign.

Two sides bereft of confidence locked horns with Barca, without Gavi, Ferran Torres, Marcos Alonso and Sergi Roberto through injury, dominating the first half but lacking any real goal threat.

Lamine Yamal, their 16-year-old sensation, brought the first save from Napoli goalkeeper Alex Meret with a fierce drive from the edge of the area.

Lewandowski’s first chance came from Ilkay Gundogan’s through-ball but his flicked finish was blocked by Meret.

The Napoli defence then opened up invitingly for Gundogan, whose dipping effort was also beaten away by Meret.

For Napoli, Osimhen was playing his first match since before Christmas but he looked isolated up front as the hosts finished the first half without a single effort on goal.

That sorry stat at least changed at the start of the second half when Matteo Politano planted an early header wide.

Gundogan should have done better with Yamal’s cut-back to the edge of the box but his side-footed effort was easily dealt with by Meret.

But Lewandowski broke the deadlock on the hour when Pedri played the ball into his feet.

Lewandowski expertly turned and fired low between two defenders and beyond the dive of Meret.

It was the Poland international’s 93rd Champions League goal, although he had not scored in his last four appearances in the competition.

But Barca had only kept one clean sheet in their previous nine matches and a blunt Napoli attack finally woke up in the 75th minute.

Andre-Frank Zambo Anguissa drove the ball forward and Osimhen rolled Inigo Martinez, who claimed he was fouled, before tucking the ball past Marc-Andre ter Stegen.

Both sides could have grabbed a winner but Napoli substitute Giovanni Simeone blazed over before Gundogan fired inches wide in stoppage time.

A stirring second-half comeback saw Premier League leaders Liverpool restore their four-point advantage at the top and avoid one of the shocks of the season with a 4-1 victory over Luton.

Chiedozie Ogbene’s early header was only the 11th league goal a visiting team had scored at Anfield this season but for a long time it looked like producing another twist in the title race as the depleted hosts struggled to find their best form.

But headers from Virgil van Dijk and Cody Gakpo within the space of two minutes turned things around before Luis Diaz and Harvey Elliott fired home to ease them away from the clutches of second-placed Manchester City.

Any slip up, even at this stage, could have significant implications in what is currently a three-way battle and without this victory City would have had the chance to go top at Bournemouth on Saturday as Liverpool are otherwise engaged in the Carabao Cup final against Chelsea.

That Wembley encounter meant no risks were taken with Mohamed Salah and Darwin Nunez, who are both carrying knocks, but with injuries had already ruling out nine other players it left Jurgen Klopp with very few options.

What the first half, in particular, showed was that stand-ins Elliott and Gakpo lacked half-a-yard of pace both over the ground and in their passing.

They were not helped by some poor decision-making by Diaz, the one regular starter in the forward line, who in only the third minute delayed his shot too long as he tried to manoeuvre it on to his right foot and then shot wide with only goalkeeper Thomas Kaminski to beat.

Luton stunned Anfield by taking the lead in the 12th minute. Tahith Chong received a return pass from Cauley Woodrow before shooting from a narrow angle and the ball squeezed under Caoimhin Kelleher and bounced up to the far post where Ogbene headed into an empty goal.

Luton’s gameplan was then to try to attack the space behind the full-backs but limit Liverpool’s options by going man-for-man in defence, which often left them two on two.

The last visiting team to win a league game at Anfield – Leeds in October 2022 – did the same.

And Luton also worked harder – Albert Sambi Lokonga easing Elliott off the ball as he looked to shoot from Gakpo’s flick-on – and smarter as the hosts resorted to firing in long-range shots.

Elliott’s radar was off from two breakaways as his passes to Gakpo were three feet short and two yards too long as the final ball continued to elude them and frustrations threatened to boil over with Klopp exploding in rage at a fan near the front of the main stand, presumably for his negative reaction to a third mis-placed Elliott pass.

The early omens in the second half were not much better as Diaz fired straight at Teden Mengi but when Gakpo’s near-post shot was turned behind Van Dijk powered home a header from Alexis Mac Allister’s 56th-minute corner.

Two minutes later it was Gakpo producing a brilliant leap to launch Conor Bradley’s cross past Kaminski, who had brilliantly saved Bradley’s deflected shot with his legs.

The Luton goalkeeper did even better to repel another powerful Van Dijk header as Liverpool turned the screw, with substitute Andy Robertson charging forward to tee up Diaz for the third.

In doing so he became the fifth Liverpool player to reach double figures, which is the best of any team in Europe’s top five leagues, with Elliott grabbing his second of the season late on as Luton remained in the bottom three.

Manchester United defender Luke Shaw is expected to be sidelined for “a few months” due to a muscle injury.

Shaw had to come off just before half time in Sunday’s 2-1 victory at Luton, a match for which he had been a doubt.

The 28-year-old left-back had previously been substituted at the break in the 2-1 win at Aston Villa a week earlier in what boss Erik ten Hag said was a precautionary move.

A statement from United on Wednesday evening said: “Luke Shaw has sustained a muscle injury and will be out for an extended period.

“Further assessment is still required to determine the severity but we expect him to be absent for a few months.”

Shaw, who has made just 15 appearances in all competitions in an injury-interrupted season, had only returned to action in January after a month out.

His latest setback – a worry for England boss Gareth Southgate ahead of this summer’s Euros in Germany – comes with fellow United left-back Tyrell Malacia also sidelined and with the club in January having opted to cut short Sergio Reguilon’s loan from Tottenham.

Sean Marks says the Brooklyn Nets must improve their "level of compete" after head coach Jacque Vaughn was fired.

Vaughn was dismissed on Monday after the Nets lost 136-86 to the Boston Celtics last week, leaving Brooklyn at 21-33 and 11th in the Eastern Conference heading into the All-Star break.

The Nets had made the postseason in the last five seasons, but a 6-18 run has left the team with it all to do if they are to keep their playoff streak going.

Nets general manager Sean Marks pointed to a perceived lack of effort as one area that must be fixed by the new head coach.

"It's about the level of compete," Marks told reporters. "We're not going to be the most talented team in the league. I'm not an idiot. I totally understand that.

"But at the same time, this is a talented group of young men out there. And my expectations, and I think their expectations, should be to hold each other accountable to do the little things. The effort plays, the loose balls, the contested shots and so forth, diving on the floor.

"These are things that should be expected when you're in a place that we're at right now, where we're clawing and grappling for every single thing we can. That's what I would hope to see over these next 28 games, and that's probably, to be quite frank, some things I haven't seen. The level of effort and the level of compete has not always been there."

Many pointed to the Nets' 144-122 defeat against the Milwaukee Bucks as the reason for Vaughn's firing. The Nets were fined $100,000 for violating the NBA's player participation policy after choosing to both rest and sit a number of key players.

However, Marks said the Bucks drubbing was not the reason for Vaughn's exit, commenting: "I don't think we lost the team that day.

"I appreciate the fact that players want to play. They want to play night in and night out.

"Again, I don't think there was one decision that ultimately affected the record or [making] this decision this day. I think a lot of things went into that."

Sir Jim Ratcliffe says Manchester United will make a fresh decision on the future of forward Mason Greenwood and will “justify it one way or the other”.

Greenwood, who is on loan at Spanish side Getafe, was suspended by United on January 30, 2022 over allegations relating to a young woman after images and videos were posted online.

The now 22-year-old faced charges including attempted rape and assault but the Crown Prosecution Service announced in February last year that the case had been discontinued.

Reports last year that United were planning to retain him following an internal investigation were met by public outcry and Ratcliffe acknowledges that a decision will have to be made when Greenwood returns about what happens next – but insists nothing has been finalised yet.

“It’s quite clear we have to make a decision. There is no decision that’s been made,” Ratcliffe said at a media briefing to mark the completion of his purchase of a minority stake in United which delegates control of football operations to his company Ineos.

Asked asked if the Greenwood situation would be a “fresh decision”, Ratcliffe said: “Yeah we will. Absolutely. We will make a decision, and we will justify it one way or the other.”

Ratcliffe added: “He’s on loan obviously, but he’s not the only one – we’ve got one or two footballers that we have to deal with and we have to make a decision on, so we will do that.

“The process will be – understand the facts, not the hype, and then try and come to a fair decision on the basis of values, which is basically: is he a good guy or not?

“Could he play sincerely for Manchester United, (play) well and we’d be comfortable with it and the fans would be comfortable with it.”

Greenwood is under contract at United until the summer of 2025.

Sir Jim Ratcliffe has jokingly questioned whether his Manchester United takeover rival Sheikh Jassim even exists after completing the purchase of a minority stake in the Red Devils.

Ratcliffe and Qatari businessman Sheikh Jassim were the two public bidders looking to take full control of United from the Glazer family which has owned the club since 2005, before Ratcliffe’s focus switched to securing a smaller stake.

His Ineos company now controls football operations as part of a deal which will see him own 28.9 per cent of the club by the year’s end.

Reflecting on the long road to the completion of the deal, Ratcliffe admitted he did find it strange that there was an apparent lack of interest in buying United in comparison to when Chelsea came onto the market in 2022 and that his main rival for full control was someone who “still nobody has ever seen”.

“The Glazers never met him. I’m not sure he exists,” he joked.

“It was extraordinary. That (apparent lack of wider interest) was confounding. There’s no comparison between Chelsea and Manchester United, the scale of Manchester United is incomparable with any of the London clubs to be honest with you.”

Asked whether he thought he may have been bidding alone rather than against Sheikh Jassim, Ratcliffe said: “They (the Qatari bid) were obviously there and there was a whole host of people on the team, on the squad. I didn’t ever meet them. But it was a very odd affair.”

Representatives who worked with Sheikh Jassim during the period of his interest in United have been contacted for comment by the PA news agency.

Ratcliffe was asked about whether he held a long-term ambition to ultimately gain full control of United and whether he was concerned that ‘drag-along’ rights held by the Glazers which could force him to sell his stake in the event they wished to sell.

“There are all sorts of scenarios. We might get hit by an asteroid,” he said.

“There have been lots of opportunities for people to come in and buy Manchester United in the last 12 months – why is it all going to change?”

Asked if taking full control was his ultimate aim, Ratcliffe said: “The ultimate aim is just for Manchester United to play really good football. It’s not about what am I going to do in five years’ time?”

Tiger Woods’ son Charlie will attempt to qualifying for next week’s Cognizant Classic, PGA Tour officials have revealed.

The 15-year-old will compete in Thursday’s pre-qualifier at Lost Lake Golf Club in Hobe Sound, Florida, which is one of four pre-qualifying sites.

Approximately 25 players and ties will advance to the full qualifier on Monday, February 26, from which four players will earn places in the Cognizant Classic from February 29 – March 3 at PGA National in Palm Beach Gardens.

The tournament has a prize fund of £7.1million and boasts a field which includes the likes of Rory McIlroy and Ryder Cup team-mates Shane Lowry, Justin Rose and Matt Fitzpatrick.

Charlie Woods has competed in the last four editions of the PNC Championship alongside his father, who was forced to withdraw from the Genesis Invitational last week due to illness.

Charlie also competed in last year’s Notah Begay III Junior Golf National Championship, with his father acting as his caddie, and finished tied for 17th in the boys 14-15 division.

Ben Stokes is poised to resume his status as an all-rounder and boost England’s bowling options on a pitch expected to be the most spin-friendly on the tour of India.

Stokes will wait to see how his body reacts to a demanding 35-minute spell of fast bowling in training on Wednesday before deciding if he will send down any overs in the fourth Test, starting on Friday in Ranchi.

He has not bowled competitively since early July and initially had no plans to do so in this series after surgery in November to have stitches in his meniscus and a bone spur removed from his left knee.

Indeed, Stokes had made a “pinky promise” with England’s physiotherapist Ben Davies not to bowl in India but that looks increasingly likely to change with his side 2-1 down in the five-match series.

“Whatever way we decide to go, (if) I feel I am capable of bowling, I will bowl,” said the England captain, who added he would buy Davies a beer if he broke his vow.

“I think there is a possible chance but I will just have to wait and see how everything is.

“I wanted to get a long spell in to see how everything coped whilst doing it then see how I pull up. It is all good at the moment. That is the longest I have bowled in six months.

“Before I went and had the surgery I was told 12-13 weeks before I could start bowling. I am two weeks ahead of that and I am quite far ahead, but there are things I have to think about other than my knee.”

Stokes returning to bowl allows England to have two seamers in their XI and select three frontline spinners in Tom Hartley, Rehan Ahmed and Shoaib Bashir, as well as the part-time offerings of Joe Root.

The playing surface in the Jharkhand capital 48 hours out from the first day of the penultimate match has cracks running down one side of the cut strip, which a bemused Stokes admitted he has never encountered before in India.

The evidence points to a wicket which will offer lavish spin but there may be some variable bounce as well which could aid the quicks as England look to bounce back from a heavy defeat in Rajkot.

“It just looked interesting,” said Stokes, echoing the observation England vice-captain Ollie Pope made a couple of hours earlier.

“If you looked down one side of opposite ends it just looked different to what I am used to seeing, especially out in India.

“It looked green and grassy up in the changing rooms but then you go out there it looked different, very dark and crumbly and quite a few cracks in it.”

One or both of James Anderson and Mark Wood could make way after their heavy workloads in Rajkot, which might mean a first appearance of the series for Ollie Robinson, who has not played competitively since the third Ashes Test last July.

Robinson, who averages 22.21 in 19 Tests, can move the new ball both ways, while his use of reverse swing on the predominantly lifeless pitches of Pakistan last winter caught the eye.

“He’s got unbelievable skills to be a successful bowler anywhere in the world,” Stokes said.

“He has worked incredibly hard while he has been out here. Not playing the first three Tests can be tough and disappointing but I’ve told him he has been a great example of doing the right things and waiting your turn if it comes.”

England’s attacking methods came in for some flak after a 434-run loss last time out but Stokes and head coach Brendon McCullum are resisting calls from some ex-players to tinker with their approach.

“You get plaudits when it goes well and a bit of s*** when it doesn’t,” added Stokes, when asked if he was surprised by some of the criticism. “It’s part of it, I’ve been around long enough to know that but we crack on.”
