Lingard came up through the Red Devils' youth academy but came close to leaving the club years ago after failing to break into the United first team.
However, following a meeting with former Old Trafford boss Ferguson, Lingard was urged by the Scot to remain at United and that he would be ready for regular first-team football.
And, with the England international having bagged 11 goals so far this season, he admits Ferguson got it spot on in terms of his predictions for the striker's career.
"Me and my dad put that trust in him [Ferguson] to say that," Lingard told Sky Sports News. "It's obviously worked. He guessed right.
"I think it's my time now. I knew we had to step up and kind of take charge. That's what I've done.
"The goals have come, which has given me confidence. Each game I just want to score now, that's my main objective."
