Former AC Milan coach Arrigo Sacchi admits he's a fan of Ralf Rangnick.
The Red Bull technical chief and former Hoffenheim coach is being linked with Stefano Pioli's job at Milan.
"I think he's a good coach, but personally I don't know him," Sacchi told Sportmediaset.
"His teams played good football."
He added: "Italy has a refusal to change. To renew it is important to have knowledge, it allows you to have innovation and courage."
