The 23-year-old has been strongly linked with a move away from São Januário this summer, with the likes of Manchester United, Liverpool, Juventus and Benfica all believed to be showing interest in the centre-back.
“I can guarantee that Dedé will stay at Vasco,” Dinamite told Lancenet.
“He has a big aim to play for Brazil and we will help him in whatever way we can to make sure he achieves it. He has a contract, and at no time has he said he wants to leave the club.”
Dedé’s contract with Vasco runs until December 2014.
