Former United youth team boss Eric Harrison helped nurture Giggs as a 17-year-old and was later his international mentor as Mark Hughes' Wales's sidekick.
And Harrison hails the brilliant winger as the perfect antidote to the modern day view of footballers.
"Ryan is a perfect role model. In my opinion he is the greatest ever player to play in the Premier League era," Harrison told the Manchester Evening News.
"Players these days don't have the best of images so they have to try to be squeaky clean. For United to have a player like Ryan, who has been a great example for 20 years at the top, is something you cannot afford to lose.
"He is a great voice in the dressing room and a great illustration of how to conduct yourself to the kids who'll face all the dangers and pitfalls of being at a huge club like United.
"Ryan is held in such high regard that everyone listens to him. I know when he was with the Welsh squad he was always there with a word or two for players, putting his arm around them with a gee-up or advice. He was great to have because you just cannot ignore that help from a player of his status.
"I know he is keen to stay in the game and I don't wish to tell anyone at Old Trafford their business, but I am 99 per cent certain he will be offered a coaching role at United. He's absolutely perfect.
"I hope his first job will be at United and long may he stay.
"But somewhere along that line could be the manager of Wales job. I have a sneaking feeling about that."
