Mohamed Salah piled more misery on West Ham with a double at the London Stadium.
Liverpool eased to a 4-1 victory over Slaven Bilic's side, who have now shipped 10 goals in their last four home games.
Salah opened the scoring after a devastating break from Sadio Mane before Joel Matip added a quick fire second.
West Ham were dreadful in the first-half but picked up after the break as Manuel Lanzini found the net.
But they were back in it for little more than 60 seconds as Alex Oxlade-Chamberlain scored at the second attempt.
And yet more shocking defending saw Salah fire past Joe Hart for his second to add to the pressure on Slaven Bilic.
Here are our player ratings.
West Ham
Hart 6 - Dreadfully exposed by shocking defence. No luck at all.
Kouyate 4 - Cannot defend yet Bilic continues to play him at the back.
Reid 4 - Booked. Struggling at the moment. Dragged all over the place.
Ogbonna 5 - Sloppy on and off the ball.
Fernandes 4 - What was he playing at for the first goal? Dragged off at the break.
Obiang 5 - Plenty of energy but lack of quality. Half-hearted challenge for fourth.
Lanzini 7 - Excellent touch and finish. One bright spark for Hammers
Noble 4 - Booked. Skipper picked up yellow for diving. Off the pace.
Cresswell 4 - Offered no protection to back three. Poor positional sense.
Ayew 5 - Hit the post early on but forgot he was playing after that.
Hernandez 5 - Worked his socks off but so isolated.
Subs
Carroll 6 (for Fernandes, 45) - Sheer presence makes a difference
Arnautovic 5 (for Noble, 60) - Not the player you need in this situation
Sakho 5 (for Hernandez, 72) - No impact.
Liverpool
Mignolet 5 - Stand-in skipper still takes unnecessary risks.
Gomez 6 - Will be disappointed by role in Lanzini goal after England call-up
Matip 7 - Couldn't miss for the second goal. Stood up to Carroll well.
Klavan 6 - Preferred to Lovren. Too lax after the break.
Moreno 6 - Comfortable evening's work for the much-maligned Spaniard.
Oxlade-Chamberlain 6 - Picked up much-needed goal but no cover for Gomez.
Can 7 - Ran the show in midfield. Liverpool can't let him go this summer
Wijnaldum 7 - Easy as it gets for the Dutchman.
Salah 9 MOTM - Such a threat. Continued fine scoring run with brace
Mane 7 - Played key role in Salah opener but tired after the break.
Firmino 6 - Quiet by his usual standards. Wasted chance to score.
Subs
Milner 6 (for Mane, 76)
Lovren (for Oxlade Chamberlain, 87)
Solanke (for Firmino, 87)
