West Ham United have announced the arrival of teenage midfielder Sead Haksabanovic from Swedish club Halmstad.
The Montenegro international has put pen to paper on a five-year contract and becomes the Hammers' fifth signing of the summer.
The 18-year-old, who became the second-youngest player in the history of Swedish league Allsvenskan in April 2015, made 70 appearances in Halmstad's first team.
"I'm really happy to be here, it's a dream come true," Haksabanovic told the club's official website. "West Ham is a big club and it is a nice feeling to have signed. The move happened quite fast - we heard that they wanted me, so I was interested to hear the plan for me and when I did I was very pleased.
"I am an attacking player, I like to dribble and shoot, but I work hard for the team. I am really looking forward to getting started, I have watched quite a few West Ham games in the Premier League and I can see that they have some great players and great fans. Now I just want to get used to being with the team and then hopefully play some games at some point next season."
The Hammers have already signed Pablo Zabaleta, Joe Hart, Marko Arnautovic and Javier Hernandez this summer.
