Eden Hazard came off the bench to fire Chelsea into the next round of the Carabao Cup.
The Belgian smashed home a late winner as the Blues came from behind to win at Anfield.
Daniel Sturridge had given Liverpool the lead earlier in the second half.
His overhead kick making amends for missing an open goal moments earlier when it looked easier to score.
But Chelsea were not done there, as Emerson tapped home from close-range after Simon Mignolet could only parry Ross Barkley’s header.
The stage was then set for Hazard, as he slipped past Naby Keita and Alberto Moreno before slamming the ball home to send his side through.
