Liverpool made it back-to-back Champions League wins after a commanding 2-0 victory over Rangers, with Trent Alexander-Arnold scoring the pick of the goals.
Jurgen Klopp's side have been somewhat off the pace this season but soon took the lead at Anfield after an excellent Alexander-Arnold free-kick past Allan McGregor.
Mohamed Salah doubled the lead with a penalty after the interval, with the insipid Rangers thankful to McGregor for preventing Liverpool from inflicting further damage.
Victory kept the Reds a point behind Group A leaders Napoli, who thrashed Ajax in Tuesday's other game, while Rangers remain bottom after yet another disappointing showing in Europe - the Scottish side conceding nine goals in three group stage matches thus far.
McGregor denied a fizzing Darwin Nunez effort after just two minutes, but the Rangers goalkeeper had no chance five minutes later when Alexander-Arnold expertly curled a free-kick into the top-left corner.
Salah saw his whipped attempt tipped away by McGregor, who then produced two smart saves in quick succession against Nunez as Liverpool dominated the first half.
Salah coolly converted a 53rd-minute penalty down the middle after Leon King felled Luis Diaz, while McGregor continued his fine individual performance by parrying over Diogo Jota's ferocious shot minutes later.
Joel Matip headed narrowly wide from a glorious opportunity before Konstantinos Tsimikas cleared off the line after Rabbi Matondo slotted past Alisson in the closing stages, as Liverpool returned to winning ways after a 3-3 draw with Brighton and Hove Albion at the weekend.
What does it mean? Reds stay on the tails of Napoli
Despite a 4-1 humbling at the in-form Napoli on matchday one, Liverpool remain within touching distance of Luciano Spalletti's side at the halfway point in the Champions League group stage.
Ajax are just two points behind Jurgen Klopp's side, but the Reds will feel confident of another victory to bolster their knockout credentials when they return to Rangers next week.
By contrast, Rangers are without a win or a goal in their first three games in Europe this season – a stark difference from their victorious run to the Europa League final last season.
Awesome Alexander-Arnold
Much has been made of Alexander-Arnold's defensive capabilities, but the right-back quietened his critics with his inch-perfect opener; his sixth free-kick goal since the start of the 2016-17 season in all competitions.
No Liverpool player can match his tally in that period, while the strike made Alexander-Arnold the first Reds man to score from direct free-kick in the Champions League since Steven Gerrard against Basel in 2014.
Goal-shy Rangers' problems continue
Rangers have won just of eight European away games in England across all competitions, with that sole victory coming in a 2-1 triumph over Leeds United in 1992.
The Scottish giants may have been beaten Europa League finalists last term, but they failed to score once again here, marking the first time Rangers have not found the net in their opening three Champions League group games.
What's next?
Liverpool return to domestic action away at Premier League leaders Arsenal on Sunday, while Rangers host St. Mirren in the Scottish Premiership a day prior.
Chelsea and Liverpool are reportedly both interested in Milan midfielder Ismael Bennacer, who could become available at the end of this season.
Bennacer, 24, spent time at Arsenal's academy before heading to Empoli, where he impressed enough to earn a €16million move to Milan in 2019.
He already has 42 international caps for Algeria after debuting as an 18-year-old, and he has started in seven of Milan's eight Serie A fixtures to begin this campaign, but his contract situation could accelerate his exit from Italy.
TOP STORY – PREMIER LEAGUE HEAVYWEIGHTS CIRCLE BENNACER
Bennacer's contract expires in 2024, at the end of next season, but the more time that passes before signing an extension, the more pressure Milan will be under to cash in as opposed to letting him leave for free.
According to Calciomercato, Milan value him at €50million as Chelsea, Liverpool and Serie A rivals Juventus all keep a close eye on his progress.
The report says to pry him away from Milan in January would take a "sensational offer", but if Milan decide to see out the rest of the season their leverage in negotiations will be significantly weakened.
Both Bennacer and team-mate Rafael Leao have high levels of interest from elite clubs, and Milan will likely not have the budget to hand out two big extensions.
ROUND-UP
– The Telegraph is reporting Manchester United will not stand in Cristiano Ronaldo's way if he wishes to leave in January.
– According to the Daily Mail, Chelsea are interested in signing Arsenal's Gabriel Martinelli.
– 90min is reporting Chelsea are also trying to push RB Leipzig into accepting deals for centre-back Josko Gvardiol and forward Christopher Nkunku as soon as possible.
– Paris Saint-Germain are hopeful of getting Lionel Messi to agree to a new contract with his deal set to expire at the end of this season, although they will hold off on negotiations until after the World Cup, per Mundo Deportivo.
– January will mark 18 months remaining on Sergej Milinkovic-Savic's contract with Lazio, and according to Gazzetta dello Sport, Italy's top clubs are all keeping a close eye on the 27-year-old's availability.
Liverpool face Rangers in a battle of Britain and Barcelona will attempt to apply more pressure on Inter boss Simone Inzaghi with a Champions League victory on Tuesday.
An army of Gers fans will travel south of the border to descend on Merseyside for a Group A clash that will give them another opportunity to secure a first point, with the Reds in second spot behind Napoli.
Barca moved top of La Liga last weekend and Xavi's side will start their third Group C game level on points with out-of-sorts Inter after losing 2-0 to leaders Bayern Munich last month.
Bayern will be expected to maintain their 100 per cent record at the expense of Viktoria Plzen, and Serie A table-toppers Napoli travel to Ajax looking to continue their brilliant start to the season.
Ahead of another mouthwatering set of matches, Stats Perform trawls through the Opta data to highlight the most noteworthy facts for each contest.
Liverpool v Rangers
This will be the first European meeting between Liverpool and the Glasgow giants in a European competition.
The Gers have only won one of their seven away games in England, that being a 2-1 Champions League victory at Leeds United in November 1992 courtesy of goals from Mark Hateley and Ally McCoist. They have suffered six defeats and drawn twice.
Liverpool's last meeting with Scottish opponents in the European Cup was back in the 1980-81 campaign, winning 5-0 on aggregate against Alex Ferguson's Aberdeen (1-0 away, 4-0 home). The Reds went on to win the competition that year.
Jurgen Klopp's side have won 13 of their past 15 home Champions League group stage matches (D1 L1), scoring 36 goals in process. Their solitary defeat was against Atalanta in November 2020
Rangers have failed to score in their two group games so far. Indeed, only Plzen (2) and Sevilla (3) have had fewer shots on target than the Scottish club (4) in this season's first two matchdays.
Inter v Barcelona
Inter have won just two of their 14 European matches against Barcelona (D4 L8), a 2-1 victory in the Inter-Cities Fairs Cup in January 1970 and 3-1 Champions League triumph in April 2010.
Barca's two away wins against the Nerazzurri came 60 years apart, winning 4-2 in the Fairs Cup in September 1959 and 2-1 in the Champions League in December 2019.
Inter have lost six UEFA Champions League matches against the Catalan giants, their most against a single opponent. Barca have only beaten Celtic (8) more times in the competition.
Barca have lost three of their past four away Champions League group stage matches (W1), as many as in their previous 25 matches on their travels in the competition (W15 D7). Xavi is only the second manager to lose his first two away Champions League matches in charge of Barcelona, along with Louis van Gaal in 1997.
Inter have lost their past two Champions League games at San Siro (0-2 v Liverpool and Bayern). Only once previously have they suffered three consecutive home defeats in the European Cup/UEFA Champions League (a run of three between February-September 2011).
Bayern Munich v Viktoria Plzen
Bayern have won all four of their European matches against Plzen, beating them twice in the 1971-72 Cup Winners' Cup and the Champions League in 2013-14.
Plzen's two away European matches against Bayern have seen them concede at least five goals on each occasion, losing 6-1 in September 1971 in the Cup Winners' Cup and 5-0 in the Champions League nine years ago.
Bayern are out to record three wins at the start of a Champions League campaign for a fourth consecutive season. In their opening three games in the previous three seasons and their two games this year, they have won all 11 matches by an aggregate score of 41-7.
Plzen have conceded seven goals in their two Champions League games this season and only kept one clean sheet in their 20 matches in the competition.
Leroy Sane has been directly involved in 14 goals in his past 11 Champions League starts for Bayern (8 goals, 6 assists). The winger could become only the second player to score in Bayern's first three Champions League games in a season, with Robert Lewandowski (in 2019-20 and 2021-22) being the other.
Ajax v Napoli
Napoli have never won away from home in the Netherlands (D2 L3) in any European competition.
Ajax have failed to win any of their past 11 home European matches against Italian opposition (D6 L5) since winning 2-1 against Roma in this competition in December 2002.
Napoli will be looking to win their first three Champions League group stage games for the first time. They are unbeaten in eight matches in the group stage of the competition (W5 D3).
Ajax have won their past four home games in the group stage of the Champions League, scoring four goals in each of the previous three (4-0 v Borussia Dortmund, 4-2 v Sporting CP and 4-0 v Rangers).
Napoli are the top scoring side in the Champions League this season with seven goals. Luciano Spalletti's side have had more shots (43) and shots on target (19) than any other team.
Other fixtures:
Marseille v Sporting CP
6 - Marseille have lost six of their eight European Cup/Champions League matches against Portuguese opponents (W1 D1).
16 - Marseille have lost 16 of their past 17 Champions League matches (W1), failing to score in 11 matches in this run, including both games this season.
Porto v Bayer Leverkusen
7 - Porto have won seven of their eight home Champions League games against German opposition (D1), winning five in a row.
2 - Leverkusen have only won two of their past 13 away matches in the Champions League (D5 L6), with three of the previous four ending in defeats without scoring.
Club Brugge v Atletico Madrid
3 - Brugge are unbeaten in all three home meetings with Atleti in European competition (W2 D1).
7 - Atleti have never won a European match against a Belgium club in seven attempts (five away, two neutral). They have played more major European games on Belgian soil without winning than in any other country.
Eintracht Frankfurt v Tottenham
4 - Tottenham have lost their past four Champions League matches against German opposition by an aggregate score of 14-3, losing twice to Bayern Munich (2-7 and 1-3) and twice to RB Leipzig (0-1 and 0-3).
3 - Eintracht have won three consecutive European games against English teams (one versus Arsenal, two v West Ham), as many as in their first 14.
Jurgen Klopp says there are no "instant" solutions in football as Liverpool look to bounce back ahead of their Champions League clash with Rangers.
The Reds failed to turn their rough form around upon their return to Premier League action this weekend when they were held to a 3-3 draw by Brighton and Hove Albion.
With just one win in their last four games across all competitions, Klopp's side - FA Cup and EFL Cup winners last term as well as Champions League finalists - risk falling short on multiple fronts this term.
But the German feels his side will be able to work out their problems, stating they must "go back to the basics" and that they cannot expect an immediate revival of fortunes.
"We realised after Napoli it was a real low point, and we had to change things quickly," he stated. "We didn't play Wolves, played Ajax, then didn't play Chelsea and couldn't keep up any momentum from the Ajax win."
"When you spot a problem and think you have the solution, you expect the solution to be instant and influential, that's never the case in football.
"When it doesn't work out, you realise step by step that you have to go back to the basics. We have to be patient again to do the right thing, and then we will be fine again."
Liverpool's mixed form has made it hard for new signing Darwin Nunez to have the desired impact after an early season red card, but Klopp is unconcerned over the forward's personal attributes.
"He is still adapting," he added. "New players come in and everybody talks about them and wants them to shine immediately and that happens from time to time.
"We had a long talk yesterday and we told him we are completely calm. It's really important in our situation that he isn't worrying. The three-game suspension didn't help him to settle, that's clear.
"The team isn't flying and that doesn't make it easier for a striker, especially a finisher. It's not that everything is clicking, that is not our situation at the moment."
Sadio Mane says he "will never forget" his time with Liverpool having made a move to Bayern Munich in the recent transfer window.
Mane joined the Reds from Southampton in 2016 and spent six successful years at the club, winning both the Premier League and the Champions League.
And while the 30-year-old now plies his trade in the Bundesliga, he says he will always have fond memories of playing for Liverpool.
"Honestly, I will never forget my time there," Mane told UEFA.com.
"I learned a lot – as a man and as a football player. The supporters were amazing, the people from the city were amazing. It is a club that will stay in my heart forever.
"It is also a legendary club – they have won everything. And also, it is the club that had all the best Champions League nights."
Mane cited the 2019 Champions League final win against Tottenham in Madrid as a particular highlight, adding: "I remember the second goal that Divock Origi scored very well. I was over the moon at that moment. I couldn't believe it.
"I just thought back to my childhood, when I was watching the Champions League. I found myself playing a final and, more importantly, winning it.
"It was amazing – 2019 was an outstanding year. The celebrations, the club, you just had to be there to understand. I think over half a million people were out in the streets waiting for us to parade our trophy. It was just beautiful."
The Senegal international has endured a mixed start to his Bayern career, scoring three in three league games to start the season but then going on a run of five appearances without a goal in all competitions before finally finding the net again in Friday's 4-0 thumping of Bayer Leverkusen.
And he admitted his move to Germany had not all been plain sailing so far, saying: "Switching from one club to another is not easy.
"I spent eight very nice years in England, six years at Liverpool [after] two at Southampton, and now I am in a new country. It is not easy because everything changes so suddenly, people, training, everything.
"Everything is changing so it is not easy at all. I need to adapt. I knew that and it came as no surprise. It is happening just the way I imagined it.
"People here are welcoming, and they're real players. People around the club are amazing so I am very happy.
"We have a very, very young squad. It's the first time in my career that I have been part of such a young group. What really stands out to me is that they're all hungry. They all want to develop and they're attentive too.
"Training sessions are as intense as the games. It's important as I think it makes a real difference and it shows. It’s so easy to play alongside these youngsters, who are massively talented and promising."
Manchester United have already conceded 14 goals in seven Premier League games this season.
United boss Erik ten Hag is weighing up his goalkeeping options, having stuck with long-term number one David de Gea since taking over.
Reports have emerged that United and De Gea are set for talks on his future, with the 31-year-old's deal to expire in 2023.
TOP STORY – MAN UTD EYE COSTA AS DE GEA REPLACEMENT
Manchester United's goalkeeper situation is in flux, with the club interested in Porto custodian Diogo Costa, according to Metro.
United have sent scouts to watch the 23-year-old goalkeeper, who has seven caps for Portugal.
The Red Devils are looking for De Gea's successor, with the Spaniard seemingly not suiting Ten Hag's possession-based style.
United also have 25-year-old England international Dean Henderson out on loan at Nottingham Forest.
ROUND-UP
– O Jogo claims former Olympiacos manager Pedro Martins could be the latest Portuguese coach to take over at Wolves, following Bruno Lage's dismissal on Sunday. The Telegraph reports that under-fire Sevilla boss Julen Lopetegui may be considered and Celtic manager Ange Postecoglou has also been discussed.
– Juventus and Real Madrid will rival Liverpool in the race to sign Belgian midfielder Youri Tielemans from Leicester City, claims Calciomercato.
– LaLiga pair Sevilla and Valencia are both interested in Manchester United forward Anthony Martial, reports Todofichajes.
– Tottenham and Juventus target Nicolo Zaniolo is set to pen a new deal with Roma, re-committing on a €4million per-year deal until 2027, according to Calciomercato.
– Everton's Venezuela international striker Salomon Rondon has interest from UAE club Sharjah FC but is likely to stay with the Toffees, reports Liverpool Echo.
Erling Haaland has enjoyed a remarkably prolific start to life in England with Manchester City.
Ahead of Sunday's derby with Manchester United, Haaland has netted 14 goals in 10 appearances in all competitions for City since his off-season move.
The Norwegian joined City from Borussia Dortmund in June on a five-year contract, following interest from several top clubs.
TOP STORY – MAN CITY CONSIDERING IMPROVED HAALAND DEAL
It is only a few months into Erling Haaland's first Manchester City contract, but the English champions are ready to offer him a new and improved deal, reports the Daily Star.
City have gone early on revised contracts in the past to shore up key players before they become transfer targets for rivals and they will do the same with their star striker if he can keep up his goalscoring prowess.
Haaland is already one of City's top earners alongside Kevin De Bruyne, pocketing around £375,000 per week.
City may opt to bump that up with an improved extension in May, with reports that Real Madrid are planning to chase him in 2024, when they can trigger his termination clause.
ROUND-UP
– PSV's hot property winger Cody Gakpo is attracting interest from Milan, claims Calciomercato. The 23-year-old Dutchman was pursued by Manchester United and Leeds United during the last transfer window, and has also been linked with Southampton and Everton.
– The Sun reports that French Ligue 1 outfit Nice are in the lead in the race to sign Shakhtar Donetsk winger Mykhaylo Mudryk. The Ukrainian club are demanding £50million (€56.86m) for him.
– Arsenal are in the race for Wolves midfielder Ruben Neves, claims the Express, and are hoping to win him over amid rival interest from Barcelona, Liverpool and Manchester United.
– West Ham United are the latest club to be interested in Club Brugge winger Noa Lang, reports Calciomercato. Milan are also credited with an interest in the 23-year-old.
– Arsenal are weighing up a move for Bayer Leverkusen's Ecuadorian defender Piero Hincapie, according to Teamtalk.
– Marca claims Sevilla could bring back former boss Jorge Sampaoli, who led the club from 2016 to 2017, if they dispense with current head coach Julen Lopetegui after their poor start to the campaign.
Gabriel Jesus is setting the standard that is driving Arsenal's early-season charge at the top of the Premier League, and he came up trumps in his first north London derby.
Arsenal's win over Tottenham came in Saturday's early game and was followed by plenty of drama later, as Liverpool were held by Brighton and Hove Albion in a rip-roaring match at Anfield featuring a Leandro Trossard hat-trick.
Newcastle United earned a second win of the season, brushing off Fulham at Craven Cottage, while Graham Potter's Chelsea had substitute Conor Gallagher to thank for their late winner at Crystal Palace.
With goals and drama in abundance, here Stats Perform unpacks the pick of the data.
Arsenal 3-1 Tottenham: Ton up for Kane, but it's Partey time for Arsenal after derby win
Harry Kane became the first Premier League player to reach 100 away goals in the competition, but that was scant consolation for Tottenham after this derby defeat.
Arsenal were able to celebrate a third successive home league win over Spurs – the first time that has happened since 2013 – and they are unbeaten at home in this fixture for 12 games now (W8 D4).
It was a win to savour for Arsenal, with Thomas Partey's opening goal rounding off a 21-pass move, going down as the Gunner's sixth goal since December 26, 2019 to have come from a sequence of 20 or more passes. Only Liverpool and Manchester City have had more in that time.
Jesus restored the Gunners' lead after Kane's penalty brought Spurs level, with Arsenal's close-season signing from City having managed five goals and three assists already in the Premier League. Only Erling Haaland (12) has had more goal involvements in the early weeks of this season.
It fell to Granit Xhaka to put the seal on the win, after Emerson Royal was sent off. The Arsenal midfielder grabbed his second Premier League goal of the season, with this the first campaign where he has managed more than one league strike since he netted four times in the 2018-19 season.
Liverpool 3-3 Brighton and Hove Albion: Trossard heroics stun Reds
Leandro Trossard became just the third opposing player to score a Premier League hat-trick at Anfield, joining former Coventry City winger Peter Ndlovu and ex-Arsenal forward Andrey Arshavin in that curious club. Arshavin famously hit four in a 4-4 draw in April 2009, the highest-scoring Premier League draw at Liverpool's home ground.
Saturday's feat meant Belgium international Trossard became the first Brighton player to score a Premier League hat-trick, and it left Liverpool four points behind the Seagulls after seven games each, with this game quite the baptism for new boss Roberto De Zerbi.
Liverpool have just two wins from seven games, and they were thankful for Roberto Firmino's sharp finishing as he scored twice, taking his tally for the season to five Premier League goals, all coming at Anfield. He scored five across the 2021-22 season, all away from home.
Mohamed Salah remains stuck on two goals in this campaign but he marked his 200th Premier League appearance with a 50th assist when he set up Firmino to trim Brighton's lead to 2-1 in the first half. Salah becomes just the third African player to reach 50 assists in the competition, after Didier Drogba (55) and Riyad Mahrez (51).
Crystal Palace 1-2 Chelsea: Gallagher returns to rock Eagles
Conor Gallagher came off the bench to deliver a 90th-minute knockout blow with Chelsea's winner against the side they loaned him to last season.
It meant Crystal Palace's losing run against Chelsea extended to 10 Premier League matches, and also boosted the Blues' record to nine wins in their last 10 away London derbies against all teams.
New Chelsea boss Graham Potter watched on in his first Premier League game since joining from Brighton, and he saw former Barcelona and Arsenal striker Pierre-Emerick Aubameyang mark his league debut for the visitors with a first-half equaliser. Aubameyang also scored in his first game for Arsenal (against Everton in February 2018).
Odsonne Edouard's opener in the seventh minute was the earliest goal Chelsea have conceded in a Premier League away game since January 2021, when Wilfred Ndidi scored for Leicester City in the sixth minute.
Fulham 1-4 Newcastle United: Magpies take flight thanks to Almiron's capital double
Miguel Almiron had been Newcastle's home boy of late, with his last seven Premier League goals coming at St James' Park, so Saturday's double at Craven Cottage bucked a trend.
A fine volley followed by a close-range finish from the Paraguayan helped Newcastle to their joint-biggest victory under Eddie Howe in the Premier League (also 3-0 vs Norwich City in April), and a biggest league win in London since beating Fulham 4-0 in May 2019.
Almiron last scored away from home in the Premier League in another 4-1 win for Newcastle – against Howe's Bournemouth in July 2020.
Fulham were hindered by a red card for Nathaniel Chalobah after seven minutes and 26 seconds, the earliest a player has been sent off for the club in the Premier League since Ian Pearce against Palace in October 2004 (sixth minute).
Brighton and Hove Albion head coach Roberto De Zerbi reflected on a "crazy game" after seeing his team draw 3-3 with Liverpool in his first Premier League match in charge.
De Zerbi replaced Graham Potter after the latter joined Chelsea last month and a Leandro Trossard hat-trick ensured Brighton left Anfield with a deserved point.
His side could have gone home with all three, with Alisson on hand to deny Trossard and Danny Welbeck further punishing a ramshackle Liverpool defence.
Trossard's third strike ultimately only proved enough to snatch a draw after Roberto Firmino's double and Adam Webster's own goal cancelled out the Belgium international's early brace, and De Zerbi was full of pride at his team's display.
De Zerbi told BBC Sport: "A crazy game. I am happy and proud for my players and my club.
"There was a possibility to win the game but Liverpool is a fantastic team. I knew before the game it could be difficult and it was very difficult.
"Of course, the point for us is really important because Liverpool at the end of the day are Liverpool but we had a lot of chances to score the goals and if we had won the game I wouldn't have felt like we had stolen anything here.
"In that moment, I didn't think we had to win the game. It is 90 minutes plus additional time at Anfield."
Brighton had only six shots, though all of them were on target. Despite the overall performance and a positive result, De Zerbi sees room for improvement.
"We have to learn how to improve with the ball possession and to increase our ball speed and it is up to us to decide it," the former Sassuolo boss added.
"It is really hard to control the game in the Premier League - only Manchester City is doing that. Our target is to start to control much more of the game."

Jurgen Klopp accepted Liverpool's defending was not good enough as a Leandro Trossard hat-trick secured a 3-3 draw for Brighton and Hove Albion at Anfield.
Trossard gave the visitors deserved two-goal lead inside 17 minutes of head coach Roberto De Zerbi's first game in charge on Saturday, but Roberto Firmino pulled a goal back before the break and equalised early in the second half.
Adam Webster's own goal put the Reds ahead for the first time, but a third clinical left-foot finish from Belgium forward Trossard with seven minutes of normal time remaining salvaged a warranted point.
Trossard became only the third visiting player to score a Premier League hat-trick at Anfield, after Peter Ndlovu and Andrey Arshavin, and Brighton could have added more goals as Liverpool's defensive frailties were exposed.
A point for Liverpool leaves them in ninth and Klopp believes his team can have few complaints, with Trent Alexander-Arnold – who was in the headlines this week after being left out of the England squad to face Germany – twice caught out as Trossard put Brighton in command early on.
Klopp told BBC Sport: "This game has different stories. There is the story of how we conceded two early goals, there is the story of how we came back in the game, then there is the story of how we threw it away.
"Brighton are a really good football team and a real team. It was a different formation, we were surprised a little bit? Yes, a little. But we were already 2-0 down when we adapted from that.
"We scored our goals which were the counter-attacks. We could have won, but would we have deserved to win? I'm actually not sure. Brighton deserved something.
"With all the good things we did during the week the confidence is a little lower and when someone stamps on it, it is really difficult. We have to accept it. Of course it is not enough for us but it is what we got.
"I spoke to the boys in a similar way to how I speak to you. I don't know how many times I have to say we need a reaction. The first goal has an impact on both teams. They were flying and we were somewhere in between. They used that for the second goal.
"We could have defended much better. It's football and you have to accept it. On a day when it starts like this, it's important to fight your way through. It would be nice if you could win it. We always have problems against Brighton who are a very good football team, but we have to do better.
"I know we have 10 points and that's the reality. I don't hide from that. We have to go together and build."
Liverpool's tally of 10 points is their joint-fourth worst total through their first seven Premier League matches of a season.
Leandro Trossard scored a hat-trick to earn a 3-3 draw for Brighton and Hove Albion in a Premier League thriller against Liverpool at Anfield.
Trossard's double in the opening 17 minutes put the visitors in command in head coach Roberto De Zerbi's first game in charge.
Liverpool hit back through Roberto Firmino before the break and the Brazil striker equalised early in the second half of a pulsating Premier League encounter.
Adam Webster's own goal put Liverpool ahead for the first time, but Trossard completed his treble with seven minutes of normal time remaining to give Brighton a deserved point.
Trossard gave De Zerbi a dream start to his reign, taking a clever flick from Danny Welbeck and drilling home with his left foot from inside the area after beating Trent Alexander-Arnold.
Alisson made fine saves from Welbeck and Trossard but was powerless to prevent the latter doubling his tally with a clinical left-foot finish after Alexander-Arnold's error.
Robert Sanchez thwarted Mohamed Salah, but the Egypt forward's touch gave Firmino the opportunity to find the back of an empty net, with the goal awarded following a VAR check for offside.
Firmino showed great composure to equalise on the break nine minutes into the second half, taking a pass from half-time substitute Luis Díaz and producing some trickery to round Lewis Dunk before applying the finish.
The turnaround looked complete when Sanchez paid the price for flapping at Alexander-Arnold's corner, with the unfortunate Webster turning into his own net.
Yet Brighton continued to pose a huge threat and, after Alisson denied Welbeck, Trossard sealed his hat-trick by superbly converting a left-wing cross.
Alexander-Arnold forced an excellent save from Sanchez in the closing stages, but Liverpool were unable to find a winner.
Jurgen Klopp does not understand why anybody would focus only on Trent Alexander-Arnold's defending when he has "world-class talent" on the ball.
Liverpool right-back Alexander-Arnold has been the subject of much debate this week after being left out of England's matchday squad to face Germany on Monday.
Reece James started the match and Kyle Walker came off the bench, while Kieran Trippier was among the substitutes.
James appears to be Gareth Southgate's preferred option in that position, but Walker has made 50 appearances under the Three Lions manager. Trippier has turned out 37 times for Southgate, starting in both the 2018 World Cup semi-final and Euro 2020 final.
That leaves Alexander-Arnold – often outstanding for Liverpool – as fourth-choice and looking highly unlikely to feature at the World Cup, even if selected in the 26-man squad.
Southgate handed Alexander-Arnold his international debut in 2018, but he has since earned just 17 caps for his country.
While the 23-year-old's creative abilities are unquestioned – he leads the England quartet in chances created (2.4) and expected assists (0.32) per 90 minutes in the Premier League in 2022 – there are doubts around his defending.
Klopp has accepted Alexander-Arnold has room for improvement, but ahead of Saturday's game against Brighton and Hove Albion, he also suggested "nobody mentions" when the Liverpool man defends well.
"It's like you have a list, bad defending and good defending, and bad defending [is] massive, and the good defending [list] is like you can't even see," he said.
"That's what I see, because I'm not dumb."
Klopp was also keen to point out some of Alexander-Arnold's shortcomings are due to Liverpool's approach, as they are "extremely brave" in their pressing and "the pitch is too big to be everywhere".
Yet even when Alexander-Arnold is directly at fault, his club manager believes there is too much focus on those shortcomings.
"There are other situations where he was not aware of the situation, where they pass the ball through him, where it was a challenge he should've won – true," Klopp said. "Every player in the league has these challenges.
"With him, you pick it out, analyse so easy. All the experts sitting there, 'in this situation, you see it's a weakness'.
"Honestly, I just don't get it, I just don't get that part of it – that we just accept that a world-class talent gets judged by the one thing he's not as world-class as in other things."
And Klopp added: "If he would not be a good defender, he wouldn't play."
Chelsea have reportedly already conducted a medical for RB Leipzig forward Christopher Nkunku with the aim of signing him at the end of this season.
It has long been thought Nkunku's time at Leipzig was coming to an end, but the Bundesliga club retained his services in the most recent transfer window, potentially setting him up for a 2023 departure.
Nkunku is off to a terrific start to the Bundesliga season, netting four goals from seven games, and while the interest in him is expected to be wide-ranging, Chelsea have used their relationship with Leipzig in an effort to jump to the front of the queue.
TOP STORY – CHELSEA COMPLETE SECRET NKUNKU MEDICAL, PREPARE TO TRIGGER RELEASE CLAUSE
According to Bild, Nkunku has a release clause in his contract set at €60million, and Chelsea are prepared to trigger it at the conclusion of this campaign.
Chelsea and Leipzig have done plenty of business together previously, including sales of Timo Werner in either direction and advanced negotiations around young centre-back Josko Gvardiol. It appears Nkunku was also discussed at length, and the German club were willing to let Chelsea take a closer look at the in-demand attacker ahead of any official bids being made.
With Gvardiol also remaining a potential target for new Chelsea coach Graham Potter – with his price tag set at a huge €90m – this could turn into one of the most expensive package deals ever.

Liverpool manager Jurgen Klopp admits Trent Alexander-Arnold has "space for improvement" defensively when questioned over the full-back not featuring for England.
The 23-year-old was called up by Three Lions' boss Gareth Southgate for the fixtures against Italy and Germany, but failed to get on the pitch in either as Chelsea man Reece James played both matches.
While Alexander-Arnold has shown plenty of attacking ability over his career, registering 45 assists for Liverpool in 167 Premier League appearances, his defensive capabilities have been questioned.
And Klopp feels Alexander-Arnold could become more solid going backwards, telling reporters ahead of Liverpool's match against Brighton and Hove Albion: "I see him differently. People say he's not a good defender. That's not true.
"He is a good defender, but he doesn't always defend good. That's true. That's what we're working on. He's a young player, he's 23, and there's space for improvement definitely.
"We only discuss it on the level we discuss it because his offensive impact is so extreme. Is he always exceptional? No."
Klopp also feels the discussion over Alexander-Arnold's role in the England squad is harming their chances at the upcoming World Cup, after former Aston Villa forward Gabby Agbonlahor said the defender should "retire" from international duty until Southgate left his position.
"We can now discuss selections until the World Cup starts. It's one of the reasons why you make massive stories of why the [England] team can't prepare properly," Klopp added.
"If you ask me for my honest opinion, it will create headlines, that's clear. Do you want that? It helps Germany maybe, but not England.
"If you want them to play a good World Cup, then don't cook it too hot. Otherwise, you discuss this until November, and don't let them work properly.
"I think you could see a little bit, England are slightly under pressure because they don't play to their full quality in this moment.
"Let them do the job, and criticise afterwards."
