Ferguson finally walked away this summer after 26 amazing years in which he won a staggering 13 Premier League titles. Moyes must now carry on that success, but he realises matching what Ferguson did during his time at Old Trafford will simply not happen.
"It is impossible," he said. "To manage at this level for 26 years and have his success; I don't think there will be any other manager who will do that amount of time at a club like Manchester United."
Yet that does not mean Moyes is intimidated by Ferguson's presence.
"I hope he is sitting in the directors' box," said Moyes.
"He has been so good and I've already called him two or three times for advice on matters. He's not there to pressure me. He is the person who told the board I should be the next Manchester United manager."
Yet, as with most individuals, there are some occasions when even Moyes defers to the 71-year-old and, crucially, one of them was being told he had got a job the Scot was not even aware existed when he got summoned to Ferguson's plush Cheshire home.
"I knew nothing at all about it until Sir Alex gave me a call and asked me to come to his house," said Moyes.
"I was expecting him to say 'I'm gonna take one of your players,' but the first thing he said to me was, 'I'm retiring'. And I said, 'yeah, when?' because he was never retiring, was he?
"And he says, 'next week,' and his next words were 'and you're the next Manchester United manager'. So I didn't get a chance to say yes or no, I was told I was the next Manchester United manager by Sir Alex, so for me that was enough.
