Yildiz and Juve will meet Galatasaray tonight in the first-leg of their Champions League playoff.
Terim told Tuttosport of Yildiz: "A real star, as his last name suggests. I look at him with great pleasure. He is one of the best players not only in Juventus but also in Europe. Some players are born to be stars. Kenan is one of them. I'm glad he extended his contract. I think they needed an icon like him.
"After (Alessandro) Del Piero, which I have enjoyed watching throughout his career, he may be an idol who can meet Juve's needs in this regard. I don't know what will happen in the future, but in this period when we change jerseys frequently, I must say that Juve's position for Kenan is something to be proud of.
"If he continues like this, his career at Juventus could reach Del Piero's level and become one of the best names in the club's history, joining legends such as (Michel) Platini, (Zinedine) Zidane, (Gianluigi) Buffon and my dear friend (Pavel) Nedvěd.
"And let's not forget that he is still very young. He visited me last year and made me very happy. He addressed me as 'Sir'. I realised that Kenan is not only a good player, but also a very respectful and honest person. I hope he continues to make us proud.”
