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.
