Roma have completed the signing of Dinamo Zagreb midfielder Ante Coric on a five-year deal.
The Croatia international joins the Giallorossi until June 2023 for an initial €6 million (£5.2m) fee with a 10 percent selling on fee due -- or €2m (£1.7m), whichever is greater -- to the Croatian champions if he leaves before the end of June 2020.
"I am very pleased to be at Roma, one of the biggest European clubs," he told Roma's website.
"I have given everything to reach this level, and I cannot wait for the chance to start showing what I am capable of."
The 21-year-old made his Dinamo debut in 2014 and went on to make almost 150 first-team appearances for the club and contributed 23 goals.
His trophy count with the Croatian outfit includes four league titles and three Croatian Cup successes.
Roma's sporting director Monchi said: "We are delighted to welcome Ante Coric to the club. I believe that, with his signing, we have secured one of the emerging talents of European football.
"I hope that, with hard work from the player and the guidance of the coach, that talent can develop even further -- and we can enjoy its quality for a long time."
