For the first time since November 1, 1986, United will play a league game tonight without Sir Alex Ferguson at the helm.
It is so long ago, Peter Davenport got the last goal not celebrated with Ferguson as manager.
Even for Moyes, it is a strange feeling.
Which is why he had a closed-doors try of Ferguson's chair looking out on to the Aon Training Complex.
"Sitting in the chair for the first time felt odd," said Moyes.
"I did it myself with nobody looking. I thought I would have to see how it feels in case anybody thought I looked stupid.
"He will be a great mentor for me. I want him around.
"He is recovering from his hip operation but I went to see him the other day and he was great.
"Within the first 10 minutes of him telling me I was getting the job, we had already had discussions about the team, what would have to be done and what was expected; like sponsors, media and all the things that come from a big club.
"There were no airs and graces. He didn't feather it. He told me straight and he told me what it was going to be like."
One of Ferguson's favourite phrases was that he did not need to go looking for trouble, because trouble would always find him.
Moyes must have felt a little like that this summer as the Wayne Rooney saga rumbled on.
Whilst the striker's personal feelings about United remain unknown, the club have resolved to keep him and he was on the flight to south Wales last night ahead of a likely appearance amongst the substitutes.
With fixtures against Chelsea, Liverpool and Manchester City looming, Moyes could do with extending his own excellent record at Swansea.
If it starts to go wrong though, the Scot is confident there will be no pressure applied from above.
"I have really good owners who don't panic," he said.
"We have stability at the club. We know where we are going and how we work.
"There is not a panic on every time we have a defeat, not quite reaching expectations is not something to really bother yourself with.
"Obviously I am aware of the job - to continue the success of the club.
"But the owners have been fantastic in their calmness, their openness and their support.
"What they want to do with the club is incredible, it really is.
"They see stability and continuity as really important so one-off results are not really interesting to them."
