Borussia Dortmund are to sign 19-year old Boca Juniors defender Leonardo Balerdi, the Argentine club's chairman said on Friday.
Daniel Angelici told a Buenos Aires radio station that Balerdi would fly to Germany on Monday.
Subject to a medical he will sign what sources inside the club said was a five-year deal for a fee of £14m.
Balerdi has played only five games for the Argentine giants but is one of the most highly rated young players at the club.
Usually a central defender, he is currently with the Argentina Under-20 team preparing for the South American championship that begins in Chile on January 17.
Balerdi emerged as a surprise transfer target for Borussia Dortmund after Manuel Akanji suffered a groin injury in the defeat by Fortuna Dusseldorf last month.
