Scholes who has recently vacated his position as Oldham manager, confessed he isn't even sure on the specifics of a technical director's role, after Ed Woodward held talks with Ferdinand over the post.
He told BBC Sport: “It seems like a waste of time to be honest with you.
“I don't understand why clubs need a director of football if you've got a manager. Whether Rio is the right person, I don't know. I don't even know what a technical director is, what does a technical director do?"
He added: “I think Sir Alex Ferguson always wanted ex-players involved with the club, whether it was coaching or roles above that. But it never really happened, and he never really got his way.
"You look at people like Edwin van der Sar. He went to college to get qualified for the role he is doing now. What Edwin is doing at Ajax is amazing.
“That's always the model Sir Alex wanted and never really got.
“Rio is a really experienced player. (But has he) got the qualifications to do a role like this? I don't know."
