Liverpool wrecked Manchester City's hopes of returning to the top of the Premier League and delivered more evidence of vast improvement under new manager Jurgen Klopp with an emphatic victory at The Etihad.
Klopp's side tore City apart with a dazzling first-half performance, which saw them take a 3-0 lead through Eliaquim Mangala's early own goal and cool finishes from Philippe Coutinho and Roberto Firmino.
Sergio Aguero gave City faint hope when he pulled a goal back on half time but City were undermined by shambolic defending as they failed to cope with the absence of injured captain Vincent Kompany.
Liverpool, however, never looked like conceding their advantage and Martin Skrtel's thunderous late fourth confirmed their superiority as they added this fine away win to their recent victory at champions Chelsea.
