Giggs inked a new 12- month deal with United yesterday.
"Those two will join my technical staff," said Ferguson on Friday. "Everything is ready for that.
"I do not want to put pressure on them and I think, for my direct successor, it must be a coach with experience. They (Giggs and Scholes) must start with youth players, reserves.
"They have time, though. In 10 years, we'll see where they are.
"Both are intelligent, determined workers. They will be with us. I see them integrated in the staff, just like Gerd Müller and Sepp Maier at Bayern Munich."
