Barcelona completed a deal for 17-year-old Alen Halilovic last week.
Halilovic has drawn comparisons to Lionel Messi, though he was used by Dinamo on the right wing like Arjen Robben.
"I'm fully aware of how pretentious this may sound," Dinamo's director of football, Zoran Mamic, told the Spanish Canal+ in 2012. "But he's a Messi-type player if there ever was one."
Halilovic has an excellent first touch and strong left-footed shot who may be at his best in an attacking central role.
