Sadio Mane lifted Liverpool’s recent gloom by scoring twice in two first-half minutes to see off top-four rivals Tottenham Hotspur at Anfield.
The forward put the Reds ahead when he ran onto Georginio Wijnaldum’s pass, holding off Ben Davies to fire in.
He doubled the lead 138 seconds later, pouncing on a loose ball from close range after keeper Hugo Lloris denied Adam Lallana and Roberto Firmino.
Second-placed Spurs rarely threatened as Liverpool moved within a point.
The visitors’ best chance fell to forward Son Heung-min, whose fierce, angled shot was blocked by Reds keeper Simon Mignolet shortly after Mane’s second.
Spurs remain nine points behind leaders Chelsea ahead of the Blues’ trip to Burnley on Sunday.
Liverpool, who had not won in their five previous matches, move back up to fourth.
