Ferguson also had a testing start to his reign and he was not following an icon who had just enjoyed a near-27-year trophy-laden spell.
"The thing about coming to a club like United is you can never get away from the expectation and I learned about that quickly," said Ferguson at a question and answer session for a 1,700-strong audience at The Lowry Theatre in Manchester to coincide with the publication of his autobiography.
"I spent a lot of stupid time looking at history, getting out early results from the 10 previous seasons and it was doing me no good, I was getting nowhere with that.
"I learned you had to look at your own situation.
"Winning a trophy at any time is important at this club."
