THE HAGUE, Jan. 31 (Xinhua) -- Ajax have signed up sc Heerenveen midfielder Daley Sinkgraven on Saturday.

The 19-year-old Sinkgraven agreed a four-and-a-half-year contract until mid-2019 with Ajax. He had a contract until 2017 at Heerenveen, which will according to reports in Dutch media receive around 6.5 million euros for the Dutch youth international.

Last Friday against FC Dordrecht (0-0) Sinkgraven played his last of 35 Dutch league matches (four goals) for Heerenveen. 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 one year ago.

Ajax and sc Heerenveen also reached a deal 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.
