Dutch football club Ajax have signed SC Heerenveen midfielder Daley Sinkgraven.
The 19-year-old Sinkgraven signed a four-and-a-half-year contract until mid-2019 with Ajax Saturday, reports Xinhua.
He had a contract until 2017 at Heerenveen who will, according to reports in Dutch media, receive around 6.5 million euros for the Dutch youth international.
Last Friday, Sinkgraven played his last of 35 Dutch league matches (four goals) for Heerenveen against FC Dordrecht (0-0).
The son of former Dutch professional player Harry Sinkgraven, who played for Groningen, Cambuur and Zwolle, broke through via the youth ranks of Heerenveen and debuted in the first team over a year ago.
Ajax and Heerenveen also agreed on a loan deal for Lerin Duarte from Amsterdam to Heerenveen.
The 24-year-old midfielder had failed to impress at Ajax since his move from Heracles Almelo in the summer of 2013. He will now play for Heerenveen for the remainder of this season.
