Liverpool came from a goal down at Anfield to thrash 10-man West Ham 5-1 and book their place in the fourth round of the EFL Cup.
The victory piles more misery on Hammers boss Julen Lopetegui, who has endured a frustrating start to his tenure.
EFL Cup holders Liverpool did not have it all their own way, as they fell behind to Jarell Quansah s own goal in the 21st minute.
West Ham s lead lasted only four minutes, though, with Diogo Jota heading home from close range to restore parity.
Jota doubled up shortly after half-time, tucking in after fine work from Curtis Jones, though West Ham were left angered after their appeals for a Joe Gomez handball at the other end were dismissed.
Mohamed Salah slammed home a third after replacing debutant Federico Chiesa, and any hopes of a West Ham comeback were ended when Edson Alvarez received a second yellow card.
A West Ham capitulation followed – Cody Gakpo scoring twice in the space of three minutes to ensure Liverpool replicated the 5-1 victory they claimed over the Hammers in the quarter-finals last season.

Data Debrief: Reds burst Hammers bubble again
Liverpool have lost just one of their last 57 home games against West Ham in all competitions (W42 D14), a run stretching back to 1964 – that sole loss came in August 2015 in the Premier League (0-3).
The Reds dominant victory on Wednesday means the EFL Cup holders have not failed to reach the fourth round of the competition since 2013-14, when Swansea City lost to Birmingham City.
