Liverpool weathered a spirited second-half fightback as a 15th straight Premier League win defeated Chelsea 2-1 and maintained their perfect start to the season.
Trent Alexander-Arnold's thunderbolt and Roberto Firmino's free header, either side of a disallowed Cesar Azpilicueta equaliser, saw the league leaders open up a two-goal lead inside half an hour at Stamford Bridge.
Chelsea midfielder N'Golo Kante's brilliant solo effort set up a tense final 19 minutes in which substitute Michy Batshuayi and Mason Mount spurned glorious chances to earn Frank Lampard's side a point.

How Liverpool withstood Chelsea fightback
If Manchester City's demolition of Watford on Saturday showed the champions would not relinquish their crown without a fight, then Liverpool's navigation of one of the Premier League's toughest away assignments proved yet again the Reds are more than capable of going toe to toe with their title rivals.
It took just 15 minutes for the visitors to take the lead as Alexander-Arnold lashed a venomous effort past Kepa Arrizabalaga into the top corner after Mohamed Salah rolled a free-kick from the edge of the area into his path.
Tammy Abraham, an isolated figure as Chelsea's lone frontman against Virgil van Dijk and Joel Matip, was presented with a gilt-edged chance to introduce himself to the game on 24 minutes but, having latched onto Azpilicueta's through ball, he failed to draw the hosts level, firing straight at Adrian in the Liverpool goal.
Chelsea's visible improvement culminated with Azpilicueta finding the back of the net after Fabinho failed to clear Willian's drilled cross into the area, but VAR found Mount to be offside in the build-up, and the jubilation inside Stamford Bridge evaporated in an instant.
And Liverpool rubbed further salt into Chelsea wounds two minutes later as some suspect defending at a free-kick left Firmino unmarked in the box and he guided Andrew Robertson's cross beyond Kepa with a header into the top corner - the Reds' 34th league goal from a set-piece since the start of last season.
Chelsea could have reduced the arrears on the stroke of half-time but Abraham glanced a header wide, while Marcos Alonso drilled crossed was gathered at the second attempt by Adrian after his initial spill brought pressure from the Chelsea attackers.
Liverpool looked to end the game as a contest early in the second period, but a stunning diving save from Kepa to deny Firmino's brilliant volley into the turf kept Chelsea clinging on.
Chelsea struggled to contain Liverpool as they grew in confidence, but they grabbed a lifeline and swung the momentum in their favour on 71 minutes when Kante waltzed through the defence and completed a stunning solo effort with a curler into the top corner.
Kante's moment of magic inspired a late Chelsea revival but they failed to capitalise on it as Batshuayi's wide glancing header and Mount's drive over from Alonso crosses saw Liverpool win yet another game.
Liverpool's 15th straight win in stats
- Liverpool are the first team in top-flight history to win their opening six matches of a top-flight season in two consecutive seasons.
- Chelsea have conceded 13 goals in their six Premier League matches this season - their most after six league matches of a season since 1978-79 (also 13), when they went on to finish bottom of the First Division.
- Liverpool have won their last 15 league matches - the only team with a longer winning run in top-flight history is Manchester City (18 between August and December 2017).
What the managers said…
Jurgen Klopp: "It was a really good performance and we scored two wonderful goals. It was an exciting game and it was intense. You will never win at Chelsea without putting a proper shift in, and I think we deserved the three points. 15 straight wins is exceptional, but what can I say? We try not to think about it, we just do what we have to do in the next game and fight for each ball and it is always really hard work."
Frank Lampard: "We didn't deserve to lose - we could have won. I don't want to sound naïve but to concede from a cross for Firmino is ridiculous. He shouldn't be having a free header in the box. I thought we were the better team, that's why the crowd clapped the team off although we lost."
