Philippe Coutinho admits Liverpool must learn from Tuesday's 3-3 Champions League draw with Sevilla, despite the result keeping them on course to win Group E.
Jurgen Klopp's side looked to be coasting to victory on Spanish soil when they led 3-0 at the break, only to suffer a worrying second-half collapse that once again raised questions over their defensive deficiencies.
Wissam Ben Yedder scored twice before Guido Pizarro struck a dramatic late equaliser to rescue a point for Sevilla and deny a shell-shocked Liverpool from qualifying for the knockout stages.
Coutinho put the capitulation down to the players losing focus after such an impressive first half, something they can ill-afford to let happen again in the future.
