The Uruguayan is yet to feature for Bologna this season.
"The boy has a lot of quality,” Vincenzo D’Ippolito told ItaSportPress. “The fans are following him with particular interest.
“Unfortunately Pioli currently prefers Christodoulopoulos to Diego.
“But I hope that can change soon and he will be taken more seriously.
“I think that if he had stayed at Inter then maybe he would have played more, because I know Mazzarri really likes him.”
