In truth, attitudes improved among a majority of the fans on Tuesday morning when United announced they had parted company with David Moyes.
But in his first press conference since taking over, Giggs cemented the new feel-good factor at Old Trafford with just a few sentences.
Speaking at the same time and in the same room that Sir Alex Ferguson traditionally held his weekly press conferences, Giggs talked of "pride" and "passion."
These are the things United managers should talk about. It was a far cry from "try" and "hope."
It should hardly have been a surprise that Giggs spoke so well at Carrington on Friday morning. The last time he was in front of the press it was with Moyes ahead of the first leg of the Champions League quarter-final with Bayern Munich. One spoke in a way you would associate with a United manager. The other did not.
There was still a hint of Giggs' sense of humour when he told the gathered reporters he'd used his new power to award himself a five-year deal.
But behind the smile, there was a steely resolve to ensure this season ends on a high note.
I'll tell the players just to try to enjoy yourself, express yourself.
I've come into the job and my immediate aim is to win on Saturday and I felt just the way to do that is to make training as enjoyable as I can so they can go out and play and they have done that.
It's going to be my philosophy, obviously the Manchester United philosophy as I've been here for all my career.
I want players to play with passion, speed, tempo and be brave with imagination, all the things that are expected of a Manchester United player.
After what they've endured these last 10 months, it will have been enough to make some United supporters cry with joy.
They finally know their team is in safe hands.
There is no one who knows better than Giggs what is expected of a United team. His first press conference was evidence enough of that.
He won't get the job permanently this time. The opportunity has come a little too early. It may even be a while before he is seriously considered for it.
But just four days into his short reign, the signs are positive that he can one day handle the immense responsibility.
Of course, Giggs' suitability for the job will be determined by results. It is not enough just to talk like a United manager. You have to win like one as well.
The Welshman, who has been as the club since he was 14, knows that better than anyone.
And judging by his performance in front of the cameras on Friday, he's already succeeding in one of the areas Moyes failed.
It was something 11 years at Everton couldn't prepare Moyes for. It's something his successor has acquired during a lifetime spent at Old Trafford.
Giggs has the next four games to show he is a United manager in waiting. Sitting in Ferguson's old seat on Friday morning, he got off to a flying start.
