Ferguson has joined forces with British philanthropist Sir Michael Moritz to match every donation made to the Rashford-championed FareShare programme to help tackle child food poverty.
When asked if he had any advice for Rashford, Ferguson added: "He should be giving me some advice because what he's doing at 23 years of age is fantastic for a young person.
"I have no need to tell Marcus because I think there's humility in the way that Marcus lives his life.
"His feet are on the ground. There are great qualities to carry you through life, there's no question about that.
"And the football hasn't changed him.
"There is a danger in football that it can change people. Money can change people. Stardom can change people.
"Getting to a position in life can sometimes be a problem because not everyone can carry success well.
"And at the moment Marcus is doing that very, very well."
