The 24-year-old - who currently plies his trade with Vasco da Gama in his native Brazil - has a reputation as one of the most highly rated centre-backs in South America at the moment, alerting the attention of a number of top European clubs.
Red Devils boss Sir Alex Ferguson has been credited with an interest in bringing Dede to Old Trafford, while Liverpool manager Brendan Rodgers is also believed to be keen to add him to his Anfield ranks ahead of the 2013/14 campaign.
However, both Premier League clubs face a significant fight to secure the player's signature, after Giuliano Aranda revealed that he has already held talks with Corinthians, and also commented on speculation linking his client with a move to Russia or Italy.
"Corinthians is a concrete possibility," he told Calciomercato.it. "We are not talking about enquiries here, but actual negotiations.
"It is difficult to say they are very close to a deal, but we will say Corinthians is a concrete possibility.
"Milan? No official bid has arrived from Italy, so as of today it is difficult to say he could go to Serie A. We'll see. The only proposal has come from Russia."
Dede looks set to follow in the footsteps of international team-mates Neymar and Leandro Damiao by shunning interest from across the Atlantic - in this case Manchester United and Liverpool - in order to remain in Brazil, ahead of the World Cup in 2014.
"Many clubs are following Dede, but he has a contract with us and he wants to stay until the World Cup, which will be played in Brazil," confirmed Vasco da Gama president, Roberto Dinamite in an interview with Tutto Mercato.
"I can say that Dede wants to stay here with us until 2014."
