That Moyes was handpicked to take over at Manchester United by Sir Alex Ferguson does not reduce the enormity of the task.
And, speaking to newspapers on the club's five-match pre-season tour, Moyes, while expressing excitement at what lies ahead, also accepts the reality.
"There has to be an element of fear that comes with managing a club like Manchester United," he said.
"It keeps you working, it keeps you focused and helps you try not to take your eye off the ball.
"Someone said, 'You'll do it easy'. I'm not saying who it was but I don't take that as a given, because I know it's going to be really hard at Manchester United.
"But in the same breath it is a great one (job) because of what I have available and what Sir Alex has left."
Moyes has repeatedly underlined his intention to ask Ferguson for advice. But he is also acutely aware he must step out of that vast shadow and stamp his own imprint on United if he is to make a success of the job.
"It has to be a new era," he said. "My job now is to make my history.
"I'm going to follow someone who has made incredible history. I think about Matt Busby's history and then Alex Ferguson's history - they could do a film about it.
"I have to make sure now that my history and my time is something which the fans and people in the future talk about."
The major positive for Moyes is that the players now under his charge have been responsive to the way he has gone about his work.
"Sometimes when there is a change - and I heard some of the players saying it - you have to impress the new manager," he said.
"I have got to say I have been incredibly impressed about how the players have gone about their work.
"There's not been a day when I've had people 'throwing out' [slacking off]. If anything, they're enjoying it and they're asking for more."
Already though, Moyes has shown a willingness to let his squad know if he feels more is required.
An intense person by nature, the Scot insists he is not quite as bad as he once was.
But a forthright lecture in Bangkok was a sign of his own standards.
"I'm going to drive," he said. "And I'm going to demand the best out of players. I'm going to demand that they give me more, or as much as I can get from them."
