Marcus Rashford is the golden boy at United at the moment and he has taken the Premier League by storm since his debut in February.
And it's watching players like Rashford develop that gets Ferguson excited.
He told The Sun: “When I first came to United Bobby wanted to replicate what happened in the Busby era of the young players coming through and winning five youth cups which was unbelievable.
“The essence of Manchester United without doubt is to give young people an opportunity at this club.
“Bobby Charlton absolutely believed in that and that's what I tried to do. Looking back, it's amazing the results we had and people will recognise Manchester United in many ways and especially about who the best players were.
“But believe me, the young players will always be the spirit of Manchester United."
