Diego could be on his way to Wolfsburg after general manager Dieter Hoeness confirmed talks with Juventus.
Hoeness would not reveal whether discussions in Turin were regarding a reported 16million Euros bid for the Brazilian midfielder but he did disclose the two clubs were not doing business over Wolfsburg's sought-after striker Edin Dzeko.
Hoeness told Wolfsburger Nachrichten,/i>: "I have been in talks with representatives of Juventus Turin.
"I am, however, not prepared to make any statement on the contents of these discussions and Edin Dzeko was not a player talked about.
"On this I have not changed my point of view. I am usually talking a lot within a transfer window"
Diego made his name in Germany during his three-year stint at Werder Bremen before securing a move to Italy last summer, but the 25-year-old has struggled to impress and the Serie A giants seem ready to cash in on the playmaker.
Diego's potential arrival at Wolfsburg could spell the end of Zvjezdan Misimovic's career with the former Bundesliga champions.
The Bosnia international midfielder has been linked with a move to Fiorentina, while former Wolfsburg boss Felix Magath - who was in charge when they won the title - has also been touted with bringing the former Bayern Munich youngster to his latest club Schalke.
