Man Utd legend Giggs tipped for Wales job
"I don't see why he can't follow Mark Hughes," former Wales captain Hartson told BBC Sport.
"He has worked with the best British manger; Giggsy's very calm, he is intelligent, he doesn't rant or rave and has universal respect of both players and managers.
"He is a wonderful player and been a great ambassador for Welsh football, he has captained his country and is doing his coaching badges so he would be a good appointment.
"Great players don't always make great managers but I would certainly fight his corner because his longevity at the top deserves the utmost respect.
"Giggsy would certainly put bums on seats but he would need to get results, though."
