Giggs is learning the managerial ropes under Luis Van Gaal and Robson believes the Welshman has all the attributes to make the job his own in the future.
He said: "You have to have a strong mentality in football, when you have your lows you bounce back - Ryan's got that and that's why I think he will make a very good manager.
"When you look back at his career, he's just been a fantastic player - dedicated, loves the game and he's been a real credit to the sport, that's why he's achieved so much.
"He's a coach now and working with Louis van Gaal, which should be a great partnership, because Ryan can teach Louis to know what it's all about at United and Louis will teach Ryan a lot of things about coaching."
