Egyptian Mohamed Salah became the first away player to score a hat-trick at Old Trafford for more than 18 years.
Liverpool thrashed Manchester United 0-5 on Sunday leaving fans and their under-pressure manager Ole Gunnar Solskjaer humiliated and stunned.
On a day of acute embarrassment for United and Solskjaer, 10 years and one day since they lost 6-1 at home to Manchester City, Liverpool emphasised the vast gulf between the sides in brutal fashion.
Liverpool made their intentions clear as early as five minutes into the game when Salah set Naby Keita through to put the visitors ahead.
Diogo Jota then connected to Alexander-Arnold’s delivery and slid in at the back post unmarked to double Liverpool’s advantage eight minutes later.
Salah later confirmed his availability when he thumped the ball into the roof of the net.
And before the break, the speedy forward beat David de Gea with a low effort to make it 0-4 for Jurgen Klopp’s side.
For they hoped not, a number of the home fans decided to leave at the break.
An upon return, Solskjaer reacted by sending Paul Pogba on for Mason Greenwood, but on a day when nothing went right for United even that mainly cosmetic move backfired horribly.
Salah raced on to Jordan Henderson’s superb pass to complete his treble five minutes after the break then Pogba was sent off for a reckless lunge at Keita that saw Liverpool’s midfielder taken off on a stretcher.
Thereafter, the rest was a formality as Liverpool cruised to victory in front of thousands of empty red seats deserted by the home supporters.
The three goals for Salah made him the first away player to score thrice at the Old Trafford in the Premier League.
And in all competitions, no player had scored a treble against Man United at their backyard since Ronaldo Luís Nazário de Lima in 2003 as they took on Real Madrid.
Mohamed Salah has now scored 106 goals in the Premier League, making him now the outright top African goalscorer in the competition’s history, surpassing Didier Drogba (104).
For Solskjaer, the club authorities have been steadfast in their backing for him but the shock waves of this result will have questions being asked more strongly than ever among everyone from the club’s hierarchy to their fans.
