Liverpool kept up their 100 per cent record and joined Leicester City and city rivals Everton as the only teams with three wins from three in the Premier League so far.
Jurgen Klopp’s side have come unstuck against Arsenal twice in recent months but overcame an early Alexandre Lacazette goal to run out 3-1 winners at Anfield.
The Frenchman took advantage of an Andy Robertson error to open the scoring in front of an empty Kop.
Arsenal’s lead lasted just 147 seconds though as Sadio Mane tapped in to level proceedings and Robertson atoned for his earlier mishap by giving the hosts the lead.
And Diogo Jota came off the bench to seal the win with a dream debut goal late on.
