Liverpool remain unbeaten in the Premier League this season after Sadio Mane scored his 100th goal for the club in a victory against Crystal Palace.
Jurgen Klopp’s side created numerous chances against a resilient Palace before Mane pounced on a rebound at the back post in the first half.
Mohamed Salah doubled their lead with just over 10 minutes remaining when he smashed home a flick-on from a corner, before Naby Keita’s late curling strike made it 3-0.
Meanwhile, Martin Odegaard’s first-half free-kick gave Arsenal their first away win of the season at Burnley.
The Norwegian curled home after Ashley Westwood had clipped Bukayo Saka on the edge of the area.
It was Odegaard’s first goal since joining the Gunners on a permanent basis from Real Madrid in a £30m deal last month.
Burnley were denied a chance to equalise from the penalty spot when referee Anthony Taylor overturned his initial decision after reviewing Aaron Ramsdale’s challenge on substitute Matej Vydra on the pitchside screen.
Elsewhere, A strangely shot-shy Manchester City could not find a way through a resolute Southampton side and ended up fortunate to get a draw despite the noisy backing of the home fans at Etihad Stadium.
City, who did not manage a single shot on target until the 90th minute, were sloppy in possession as well as lacking their usual spark in attack and Saints will feel they should have left Manchester with all three points, not just one.
The visitors were awarded a penalty on the hour mark when Kyle Walker was sent off for bundling Adam Armstrong over in the box, but both decisions were overturned when VAR intervened and referee Jon Moss watched replays of the incident.
