The strange thing was that you could not hear them.
When a team scores at Old Trafford you normally get a few seconds of silence and mumbles from the home fans, until the faithful in the Stretford End start the chants of "United" again.
But on this occasion the Liverpool fans' cheers were muffled by a defiant stadium, as over 70,000 Manchester United fans sang their hearts out for their club.
It was a biblical moment. It was an outpouring of emotion for a team on its knees.
As Suarez scored, the home support did not flinch. The goal was just a by-product of an expected defeat of a United team who simply do not have a clue at present.
But the time for tears is not now because United needs its supporters, but do the supporters need David Moyes?
Moyes' time at Old Trafford has been a disaster. But forget looking at the league table or the millions of column inches written about every botched transfer deal from last summer.
Forget the fact that half the United side look like they are already choosing their holiday destinations from their local travel agency in Wilmslow.
Forget that Nemanja Vidic is dreaming of warmer climates and that Rio Ferdinand is wondering how many baseball caps he sold this month.
And forget that United have forgotten the art of winning.
This team simply looks like a ship without a captain or compass, heading straight for the heart of a tsunami.
It should not be this bad, this quick.
It seems that Moyes' tenure is going to be satirised like a political farce, where the in-coming government blames the outgoing one for every poor tactic, every average footballer and every mindless decision and then continues this rhetoric for the next 10 years:
"Yes we played 4-4-2 last week, but that's because Fergie did in 1996" and "yes he plays for Manchester United, but I didn't buy him, so it is not my fault. I will buy someone who is world-class, if you vote for me at the next election."
Sir Alex Ferguson did not leave Moyes a dire football team. Yes, they were/are Champions and most United fans know they are probably not as good as that tag suggests.
But they are not this bad.
Moyes took this job knowing what it was all about. He knew the enormous task at hand and he knew the expectation.
The manager was interviewed before the Champions League clash with Olympiakos on Wednesday and gave his thoughts on a number of aspects including whether his job was at threat and the reaction of the fans at Old Trafford:
In the press conference, Moyes looks like a man reading a script that has been recently handed to him. One of the things I liked about him in the early days was his freshness, but now after a bad run, that has evaporated and only a feeling of staleness is left.
It is surely questionable whether Moyes now believes that taking the Manchester United job was the right thing to do.
Of course the opportunity to take over the biggest club in the world was something no manager could refuse, but did Moyes ever believe he had the tools to do the job?
I think he did. I think he had belief and a conviction. But he has been found out very quickly.
His tactics do not befit a club like Manchester United. His team does not play with tempo or motivation.
Yes, his golden boy Wayne Rooney runs around like a man earning £300,000 a week but the rest of them are wondering what is going on.
Juan Mata has come to United to play football. Attacking, creative football. And he ends up playing a role tracking back to cover Rafael at right-back.
We have the precocious talent of Adnan Januzaj who now looks like he's had all the freedom stripped from him as he worries about where Patrice Evra is.
And we have a world-class Dutch striker who many perceive is sulking up front. I think the only thing he is thinking is "why do we not create chances like we did last season?"
Moyes needs to decide quickly if he is going to stay with United. Roy Hodgson proved that he was not good enough to manage Liverpool but that there was life after failure.
If Moyes regrets taking the Manchester United job then he needs to correct that wrong.
In the meantime, the faithful will still sing for their team and their players, whether Moyes is standing in the technical area or not.
