Everton have sealed the deal for Croatian winger Nikola Vlasic for an initial £8m fee.
The 19-year-old joins from Hajduk Split and has penned a five-year deal at Goodison Park.
"I am very excited about the opportunity to play for this big club," he told the club's website. "The Premier League is the best league in the world and this is one of the top clubs in England. It is such a big honour for me to be here.
"When I heard that Everton were interested in me, I knew straight away I wanted to come here. Whenever someone called my manager or my father, I told them I only wanted to come to Everton."
