Diogo Jota and Cody Gakpo each scored two goals as Liverpool began their defence of the Carabao Cup by coming from behind to thrash West Ham at Anfield.
The visitors stunned the holders by taking the lead after a corner, Wataru Endo’s attempted clearance striking team-mate Jarell Quansah and rolling over the line.
West Ham’s lead lasted just four minutes as Federico Chiesa marked his first start for the Reds with an assist after the winger’s acrobatic volley into the ground bounced up for Jota to head the equaliser.
Portugal forward Jota scored his second early in the second half with a low and composed finish in front of the Kop after a lovely pass by Curtis Jones.
That goal came moments after West Ham had appeals for a penalty waved away when the ball appeared to strike the arm of Joe Gomez inside the box – with no video assistant referee (VAR) system until the semi-finals.
West Ham, who have now lost four of their seven games under boss Julen Lopetegui, responded well after their woeful 3-0 home defeat by Chelsea last weekend.
But on a frustrating night which saw Lopetegui booked for arguing with the officials as decisions went against his side, Max Kilman missed a golden chance to make 2-2 from six yards.
Soon afterwards substitute Mohamed Salah made it 3-1 after Lukasz Fabianski had kept out Alexis Mac Allister’s attempt, before Edson Alvarez was sent off for two bookings.
Cody Gakpo added to West Ham’s misery with the fourth and fifth goals late in the tie as the Hammers exited the competition at Liverpool’s hands for the second successive season.
