Ilkay Gundogan scored twice as Manchester City secured a record-equalling 14th successive win in all competitions – and a first for Pep Guardiola at Anfield - with a 4-1 thrashing of struggling Liverpool.
The Germany midfielder made amends for a first-half penalty miss with a brace after the break as the visitors cut loose to march five points clear at the Premier League summit.
Alisson's poor clearance led to Gundogan's second of the game and the goalkeeper was also at fault for City's third, as Raheem Sterling headed in his 100th for the club under Guardiola. Phil Foden rubbed salt in the home side's wounds with a superb solo goal to round out the scoring.
The result leaves Liverpool's title defence in tatters; they have lost three successive league games at home for the first time since 1963 and sit 10 points back having played a game more than the leaders.
Mohamed Salah did end a home league goal drought spanning 410 minutes when he converted a penalty having been pulled back by Ruben Dias, but Alisson’s errors helped City respond in emphatic fashion.
