Vasco da Gama are waiting on AC Milan to make them a concrete offer for Dede.
Vasco chiefs have confirmed Milan's interest in the defender.
“Vasco are awaiting Milan’s offer,” agent Giuliano Aranda told TMW.
“I believe there has been contact between the clubs and the Rossoneri’s interest in Dedè is concrete, but at the moment they have not spoken to me directly. Milan need to reach an agreement with Vasco before negotiating with us.”
