He put pen to paper on a five-year deal this afternoon, holding him to the Viola until June 30 2018.
"I am proud to be here," the Slovenian declared in a Press conference.
"From the first day that Fiorentina's proposal arrived, I immediately said yes. I wanted to come here, to join such a strong team. I was not interested in what other clubs wanted me.
