Liverpool ended Arsenal’s 10-game unbeaten run in all competitions with a devastatingly routine 4-0 victory at Anfield.
Liverpool went into the match knowing victory would see them move up to second place after West Ham were beaten at Wolves.
Arsenal, who have been in good form and were just two points behind Liverpool prior to kick-off, were, however, limited to few chances at Anfield.
Sadio Mane grabbed the opener when he headed in Trent Alexander-Arnold’s free-kick in the first half.
Right-back Alexander-Arnold was the provider again when he teed up Japanese substitute Takumi Minamino to make it 4-0 with his first touch, just 48 seconds after coming on.
Victory for Liverpool sees them jump up to second in the Premier League, while Arsenal remain in fifth.
It was a tame affair between the two long-standing rivals for most of the game but Liverpool showed their quality with a ruthless second-half display.
Jurgen Klopp’s side controlled possession before the break and had the best chances – Salah, Alexander-Arnold and Thiago were all denied by Arsenal goalkeeper Aaron Ramsdale.
Ramsdale was kept busy throughout and reacted well to stop Mane scrambling it in off the floor and made a decent save to prevent a second goal from Jota later on.
Arsenal’s Pierre-Emerick Aubameyang and Bukayo Saka were a threat on the counter-attack but Alisson was comfortable when he was called into action and centre-back pairing Virgil van Dijk and Joel Matip were solid for Liverpool.
Despite the four goals, it was rarely a contest which burst into life, though a touchline scrap between managers Klopp and Mikel Arteta ignited a reaction from the crowd in the first half.
