The headline score that sent shockwaves across the premier league and around the world.
Manchester Utd’s worst home defeat since 1955 when they were beaten by Manchester City.
This time, they were humiliated by a Liverpool side that were on a different level to Utd.
Manager Ole Gunnar Solsjkaer simply had no answer to the guile, the speed and team-work that Jurgen Klopp and Liverpool unleashed on Sunday afternoon.
A Salah hat-trick was the icing on the cake for Liverpool who lead 4-0 at the break as Utd supporters were already on their way out of Old Trafford.
There are calls for Solsjkaer to be replaced. How quickly supporters can turn on managers. Even Jurgen Klopp said in a post match interview that he felt sorry for Ole, he said he himself knows what it feels like to be in such a position. Those remarks show the calibre of Jurgen Klopp. He does not gloat when someone is under pressure.
The question for Ole Gunnar Solsjkaer is what can he do to turn around this soul destroying loss.
With the talent he has at his disposal, can he find a solution?
Next up for Utd is Tottenham away, then Atalanta away in the Champions League and back to Old Trafford to face Manchester City.
