Juventus GM Jean-Claude Blanc is delighted with their capture of Werder Bremen star Diego.
"In terms of his technical abilities, Diego is a crucial player for the reinforcement of the squad," Blanc enthused.
"We have always said that our objective is to blend youngsters and champions and Diego is the synthesis of these identities.
"He may only be 24-years-old but he has great experience after more than seven years of being a top professional.
"I'm sure that his contribution will be important in helping Juventus grow and take further steps forward."
