The patron of the Brazilian outfit stated that he has yet to hear from the Rossoneri and sent out an alert that the highly-rated defender will not be sold on the cheapVasco da Gama president Roberto Dinamite has revealed that he has not received an offer from AC Milan for Dede.
The 23-year-old has been suggested as a strong possibility to bolster the Rossoneri's back line in the summer as Thiago Silva is reportedly on the verge of completing a move to Paris Saint-Germain.
Dinamite did not exclude the possibility of letting Dede leave, but insists that he has not yet been approached by the Italian giants.
"If Milan want the defender, they must come to Brazil to negotiate," he told Sportitalia. "Right now there are no negotiations in place.
"He will only leave for a considerable bid."
Dede, who has two Brazil caps to his name, has also been linked with Serie A champions Juventus.
