Diogo Jota scored either side of a Mohamed Salah strike as Liverpool recorded an emphatic victory at Arsenal to boost their prospects of finishing in the top four.
The visitors dominated first-half possession without creating much in the way of clear-cut chances.
Roberto Firmino curled wide on the half-hour mark before James Milner fired wide of a post from the edge of the penalty area shortly before the break.
Arsenal’s Cedric Soares, who had earlier replaced the injured Kieran Tierney, tested Alisson just after the hour-mark before another substitute broke the deadlock for Liverpool.
Jota headed Trent Alexander-Arnold’s pinpoint cross past Bernd Leno just two minutes after his introduction.
Now firmly in the groove, Salah doubled the visitors’ lead before Jota produced a second from close range to seal the points.
Liverpool are up to fifth place with 49 points, two behind fourth-placed Chelsea.
Arsenal stay ninth with 42 points from 30 matches.
