Goodwillie instead moved from Dundee United to Blackburn last week after Rangers failed to agree terms with the Tangerines.
“David’s a quality player so I would have definitely liked him to join Rangers,” explained Naismith.
“But as a club we move on. It’s hard for the Old Firm to compete with Premiership teams these days because there is such a gulf in the money that can be offered.
“David can definitely make an impact with the national side. He has arguably been the best young player in Scotland over the past two or three years. Full credit to him for getting his move because he thoroughly deserves it.
“He has been through a lot of personal problems but has still managed to go out and perform every week. That’s a credit to him. He is definitely a player I really like and a good addition to the international scene.”
