Iran lost to USA 3-0 (25-23, 26-24, 26-24) in Pool G in Sofia on Sunday.
“USA came out with absolutely different six than the match against Bulgaria. We played against their second team. Our young players had the opportunity to show their talent but I think that they didn’t perform the best way because they haven’t any practice. Without practice they can’t play at this level,” Kolakovic said in the post-match news conference.
“I’m still thinking Iran has a lot of young and some really experienced players and the combination can lead to a really good result in future,” he added.
