The former Croatia international has advised the Juve playmaker to hangup his boots for the national side, while he does not think Stevan Jovetic is a world-class playerFormer AC Milan star Zvonimir Boban feels it would benefit Juventus midfielder Andrea Pirlo's form if he retired from international football with the Azzurri.
The experienced midfielder has been struggling to find his best form in the opening weeks of the 2012-13 campaign, and Boban believes representing Italy as well as competing in the Champions League with Juve could be too much for Pirlo at his age.
"I think that it's time for Pirlo to leave some duties behind. He should retire from international football," Boban stated to Sky Sport Italia.
"He has been lacking the brilliance that he showed last year, and I think it may be down to the fact that he has too many commitments. He hasn't had much rest this summer."
Boban then went on to voice his opinion that Fiorentina attacker Stevan Jovetic, who was close to joining Juve in the summer transfer window, is not of the highest caliber just yet.
"He is a superb player and I have no doubts that he would have done well at Juventus had the transfer gone through," Boban said. "Nevertheless. I do not think that he is good enough to be described as world-class."
Jovetic has netted four goals in five Serie A games this term, but was unable to score in the scoreless draw against Juventus on Tuesday.
