Liverpool earned their first win of the season in stunning fashion after equalling the record for the biggest ever Premier League victory with a 9-0 thrashing of newly promoted Bournemouth at Anfield.
Two goals inside the opening six minutes from Luis Diaz and Harvey Elliot put the hosts into a commanding position from the off.
A stunning strike from England full-back Trent Alexander Arnold which arrowed into the top corner gave Liverpool a three-goal lead in the 28th minute before Roberto Firmino got in on the act with a fourth three minutes later.
Not done there, Liverpool had a fifth before the interval, with Virgil van Dijk heading home from a corner, before Chris Mepham's own goal had the visitors staring at the prospect of an embarrassing drubbing.
A close-range finish from Firmino kept the goals coming, with substitute Fabio Carvalho's finish letting the home fans dream of a record-breaking afternoon.
Diaz's headed ninth strike came with Liverpool having five minutes to become the first side to score 10 in a Premier League match. But despite some late scares, Bournemouth did just enough to avoid suffering that ignominy.
In the early kick-off, a second-half strike from Bruno Fernandes was enough to give Manchester United a 1-0 win at Southampton.
The victory, United's second on the bounce, halted their seven-match losing streak on the road stretching back to last season and provisionally lifted them to sixth place after four games.
United began strongly after halftime, and their pressure told in the 55th minute when Fernandes, leading the side in the absence of Harry Maguire, scored with a low volley from the edge of the box after being expertly fed by Diogo Dalot.
United boss Erik ten Hag turned to Cristiano Ronaldo and Casemiro, a fresh arrival from Real Madrid earlier in the week, to see out the game and while Southampton dominated the ball, the hosts were unable to find an equaliser.
Elsewhere, Arsenal preserved the Premier League's last remaining 100% record as they came from a goal down to beat Fulham 2-1 thanks to a late winner by Gabriel at The Emirates Stadium that kept the Gunners top of the table.
The home side enjoyed overwhelming possession but a dreadful mistake by Gabriel allowed Aleksandar Mitrovic to give previously unbeaten Fulham a 56th-minute lead.
It was Mitrovic's 100th goal for Fulham but Arsenal were behind for only eight minutes as captain Martin Odegaard's deflected effort levelled it up.
Arsenal were not at their best against well-drilled Fulham, who should have equalised through Nathaniel Chalobah late on, but they stay in first place with 12 points from four games, two more than champions Manchester City and Brighton & Hove Albion.
Erling Haaland struck a second half hat-trick as Manchester City came back from two goals down at the Etihad Stadium to beat Crystal Palace 4-2.
An own goal from John Stones in the fourth minute put Patrick Vieira's Palace ahead and then the visitors doubled their lead when an unmarked Joachim Andersen powered in a header from an Eberechi Eze corner in the 21st minute.
City struggled to find their fluency but the almost inevitable comeback started in the 53rd minute when Bernardo Silva cut in from the right and his low shot took a slight deflection and beat Palace keeper Vicente Guaita.
Pep Guardiola then made a double substitution and moved Phil Foden to left-back and within a minute he had delivered a pinpoint cross which Haaland met with a fine glancing header.
The Norwegian then turned in from close range after a clever move inspired by Silva and then saved the best for last -- showing Ilkay Gundogan the pass he wanted to run on to and then holding off Joel Ward as he fired into the bottom corner.
The striker, signed from Borussia Dortmund in June, has now scored six goals in his opening four Premier League games.
Raheem Sterling's first two goals for Chelsea steered the 10-man Blues to a hard-fought 2-1 home win over Leicester City as Thomas Tuchel's side survived the early dismissal of Conor Gallagher.
Two yellow cards for Gallagher less than 30 minutes into his first league start at Stamford Bridge seemed to have left Chelsea with a mountain to climb.
But Sterling's double put the hosts in control - the opening goal a deflected, looping shot over goalkeeper Danny Ward in the 47th minute followed by a tap-in 16 minutes later from a Reece James cross.
They were Sterling's first goals since moving to London in the close season from Manchester City and he almost got another when he hit the post during Chelsea's early-second half onslaught.
But Leicester struck back in the 66th minute when Harvey Barnes exchanged passes with Jamie Vardy and drove an angled shot past keeper Edouard Mendy at his near post.
Leicester, who have struggled so far this season, pushed for an equaliser and Mendy was forced into saves from Barnes and Vardy, who also shot into the side netting. Substitute Ayoze Perez hit the bar late on.
Chelsea, marshalled in central defence by Thiago Silva and Trevoh Chalobah, held on for their first home win of the season, leaving them in sixth place with seven points from four games. Leicester are languishing second-bottom with one point.
