Diego has confirmed he is in talks with Atletico Madrid as he nears an end to his Wolfsburg nightmare.
The Brazilian has been on the fringes of Felix Magath's squad, not even making the bench in their opening two Bundesliga fixtures, and recently stated his desire to leave the club.
Atletico offered £4.3 million for the playmaker, according to AS, but Wolfsburg are thought to want double that.
Gregorio Manzano's side are looking to fill the void left by Sergio Ageuro's departure and have £38 million at their disposal from the sale of the striker.
Diego has reportedly agreed personal terms with Atletico and all that remains to be finalised is the fee for a player who cost Wolfsburg £13.5 million in the summer of 2010.
Diego told Bild: "We are still not clear, there is nothing official, but there is an offer for me.
"Atletico are a big club, but I still have a contract with Wolfsburg. This is a very important period for me."
