Liverpool midfielder Thiago Alcantara produced a masterclass in the middle of the park for Jurgen Klopp's side as they thrashed a dismal Manchester United.
Luis Diaz fired home after five minutes before Mo Salah topped off a sublime passing move from the Anfield club who went in 2-0 up at the break.
After a period where United looked to get back into the game, Sadio Mane finished clinically before Salah got his second of the evening before full-time to cap off a ruthless 4-0 demolition of Ralf Rangnick's team.
