Naldo's contract at VfL Wolfsburg is in doubt.
BILD says Naldo's current deal expires in June courtesy of an appearances clause and European qualification option.
Though it's claimed the defender's deal runs to 2017, the double clause means he can walk on July 1.
Wolves manager Klaus Allofs revealed: "We've made him a generous offer."
The 33 year-old defender has revealed interest from Manchester United and was asked about a move to England.
"My goal is to stay here," was his reply.
