Liverpool came from behind to maintain a perfect start to their Premier League title defence as goals from Sadio Mane, Andy Robertson and Diogo Jota saw off a resilient Arsenal 3-1 at Anfield.
The Gunners had also won their opening two league games of the season and hit the champions on the counter-attack to take the lead through Alexandre Lacazette.
But while Manchester City, Chelsea, Manchester United, Tottenham and now Arsenal have all lost in the opening three weeks of the new campaign, Liverpool have taken maximum points to lay down an early marker that they remain the team to beat in the Premier League this season.
The outcome of the match could have been very different had Mane not escaped with just a yellow card for an elbow on Kieran Tierney after just three minutes.
Arsenal followed the game plan that had brought them two victories over Liverpool in recent months as they dropped deep then looked to play around the Reds' press when in possession.
However, unlike when they met at the back end of last season's Premier League when Jurgen Klopp's men had already won the league or the Community Shield in August, Liverpool were far sharper in pulling the Gunners out of position.
Mane was first to threaten with a clean strike from Trent Alexander-Arnold's cross that was too close to Bernd Leno before Alexander-Arnold's deflected effort came back off the crossbar.
The only time Arsenal did manage to pierce the Liverpool press before half-time, they opened the scoring completely against the run of play.
Robertson was at fault as he spooned Ainsley Maitland-Niles's cross into the path of Lacazette, who also failed to make a proper connection but the ball bounced into the ground and looped over the helpless Alisson Becker.
Liverpool responded immediately to level within three minutes as Salah outmuscled Tierney and when his shot was parried across goal by Leno, Mane turned into an empty net.
Robertson them made amends for his previous error as Liverpool's flying full-backs combined as Alexander-Arnold's cross was this time converted by the Scotland captain.
However, where Arsenal sides of recent years might have collapsed, as they did in losing 4-0 and 5-1 at Anfield in 2018 and 2019, Mikel Arteta has instilled a new-found belief in the FA Cup winners.
The visitors were more expansive after the break and created a huge chance to level when Dani Ceballos put Lacazette through on goal, but Alisson stood up well to block the French striker's shot.
Klopp introduced Jota for his league debut 10 minutes from time and the Portuguese international should have sealed the win when he fired into the side-netting from Salah's excellent through ball.
The Egyptian was less generous moments later when he stole the ball of Jota's toes and failed to beat Leno.
But Jota did not have to wait long for his first Liverpool goal as a sweetly-struck volley found the bottom corner to show why the Reds spent £41 million ($52 million) to sign him from Wolves.
