Round-up
Leicester 1-2 Liverpool: Jurgen Klopp's men victorious despite Alisson error
Unsettled Liverpool edged past battling Leicester 2-1 after Alisson's howler threatened to blow their 100 per cent record.
First-half goals from Sadio Mane and Roberto Firmino put Liverpool in control at the King Power Stadium before the hosts hit back thanks to Alisson's gaffe.
His error, which saw him robbed of possession by Kelechi Iheanacho and resulted in Rachid Ghezzal slotting home, was the first goal the Brazilian has conceded since his £67million summer move from Roma.
But Liverpool survived to record their fourth straight win and continue their flying start to the campaign.
Leicester battled well and worried the visitors but failed to cash in once they had Liverpool on the ropes.
Manchester City 2-1 Newcastle United: Pep Guardiola's side keep up the pace despite improved Magpies display
Kyle Walker's first goal in almost three years broke Newcastle's dogged resilience as Manchester City returned to winning ways.
While normal service was not quite resumed in the 2-1 victory at the Etihad Stadium - this being their lowest winning margin at home since beating Chelsea 1-0 in March - it at least put Pep Guardiola's side back on track after last week's hiccup at Wolves.
They remain two points behind Liverpool and Chelsea, who both have 100 per cent records after four matches, but it needed a bolt from the blue to do so.
Despite Walker's prowess as a marauding full-back his last goal came in November 2015 so to see him rifle home a 25-yard winner early in the second half was something of a surprise.
Raheem Sterling's eighth-minute opener on his 100th Premier League appearance for the club was cancelled out by DeAndre Yedlin - another defender not known for his aptitude in front of goal.
Chelsea 2-0 Bournemouth: Second-half strikes help Maurizio Sarri's side keep up winning run
Pedro and Eden Hazard scored the goals as Chelsea extended their 100 per cent start to the Premier League campaign with a 2-0 win over Bournemouth.
Chelsea have been crowned champions in four of the five previous seasons in which they won their first four games, but Maurizio Sarri knows there is plenty of work to do for the Blues to be contenders this term.
Callum Wilson missed a fine opportunity for the Cherries in the first half and Marcos Alonso struck the post before half-time.
The Blues broke the deadlock against Bournemouth in the 72nd minute after great play between Pedro and Olivier Giroud enabled the Spaniard to fire into the bottom corner from the edge of the box.
Eden Hazard doubled the hosts' lead five minutes from time, playing a one-two with Marcos Alonso and firing a shot under the body of Asmir Begovic.
Crystal Palace 0-2 Southampton: First win of the season for the Saints
Crystal Palace's reliance on Wilfried Zaha was again laid bare as Southampton secured their first Premier League victory of the season in his absence at Selhurst Park.
It will soon be two years since Palace last won without their finest player, as second-half goals from Danny Ings and Pierre-Emile Hojbjerg demonstrated how vital it was that they again recently persuaded him to sign a new contract.
Summer signing Ings put them ahead just two minutes after the interval, latching onto Cedric Soares' ball and slotting between the legs of Wayne Hennessey.
Mark Hughes' men missed the opportunity to double their advantage from the penalty spot at Palace when Aaron Wan-Bissaka was penalised for handball but Hennessey saved Charlie Austin's spot-kick.
The win was confirmed late on as Pierre-Emile Hojbjerg added another.
Brighton 2-2 Fulham: Chris Hughton's Seagulls stage Amex comeback
Glenn Murray scored a second-half brace as Brighton battled from two goals down to draw 2-2 with Fulham.
The veteran striker equalised with a late penalty at the Amex Stadium, having halved the deficit with 23 minutes remaining.
Fulham, whose goalkeeper Marcus Bettinelli saved a first-half spot-kick from Pascal Gross, looked on course for victory after goals from Andre Schurrle and in-form forward Aleksandar Mitrovic either side of the break put them in control.
West Ham 0-1 Wolverhampton Wanders: Adama Traore's late Hammer blow as it's four defeats in a row for Manuel Pellegrini
Adama Traore climbed off the bench to secure Wolves' first win of the season, sending West Ham spinning to a fourth straight Premier League defeat.
The winger, a summer signing from Middlesbrough, struck in stoppage time to leave the Hammers - beaten 1-0 - without a point going into the international break.
West Ham have only once lost their opening four league matches of a season, in 2010-11 under Avram Grant - when they were relegated.
For Wolves it was a first top-flight win since beating QPR in February 2012.
Everton 1-1 Huddersfield: Hard-earned points for Terriers at Goodison
Huddersfield collected only their second point of the Premier League season after grinding their way to a 1-1 draw at injury-hit Everton.
It has been an inauspicious start for the Terriers but they battled resolutely at Goodison Park against a disjointed Everton, who found little rhythm without eight first-team members.
They maintained their unbeaten record under Marco Silva but only after Dominic Calvert-Lewin struck less than two minutes after Philip Billing gave Huddersfield a shock first-half lead.
Calvert-Lewin, starting for the first time in the league this season due to Richarlison's suspension, was one of the few Everton players to make a favourable impression and went closest to a winner, but was inches away from getting the final touch into an empty net.
A disappointing afternoon for the Toffees was compounded when Theo Walcott limped off in the second half and Silva will be hoping he avoids joining a lengthy casualty list that includes Idrissa Gana Gueye, Andre Gomes, James McCarthy, Bernard, Michael Keane, Phil Jagielka and Yerry Mina.
