The defender's agent revealed the Italian giant was indeed monitoring his client's situation in South America, but says a deal is far from close with Milan yet to lodge a bid
The 24-year-old is believed to have courted the interest of some of Europe's leading clubs including Juventus, Benfica, Liverpool, Manchester United and Valencia.
However, his agent, Guilliano Aranda, says Italian giant Milan has established contact with the Brazilian club, but stressed that an official offer has not yet been tabled.
"I believe there has been contact between the clubs and the Rossoneri’s interest in Dede is concrete, but at the moment they have not spoken to me directly. Vasco are still awaiting Milan’s offer," Aranda told Tuttomercatoweb.
Asked whether Dede held a preference on a prospective destination, Arando remained diplomatic, but did not disguise his client's admiration for the Serie A outfit.
"At the moment Dede is not thinking about a transfer. He is happy in Brazil and giving his all to earn a call-up for the Confederations Cup," he added.
"Milan are certainly a fantastic club and among the top sides in the world, so playing with the Rossoneri jersey would be an honor for the lad."
It is understood Milan views Dede as a potential replacement for Thiago Silva, who left for Paris Saint-Germain last summer.
