Juventus president Giovanni Cobolli Gigli admits Werder Bremen midfielder Diego is on their radar.
He said: "Diego is a great player who we like and interests us, but to date there are no negotiations.
"I think that his statements yesterday are normal and understandable, it is obvious that a player like him at this time of the season, when he does not even know his future, is trying to keep a foot in both camps.
"And it is obvious that we appreciate him speaking about a great club like Juve. In January, we will not be doing anything."
