Borussia Dortmund are on the verge of signing 16-year-old wunderkind Justin Lerma from Ecuador, German media reported on Tuesday. The deal with Independiente del Valle is around €9 million ($9.7 million), the reports said, with the attacker arriving in Dortmund when he is 18. Sporting director Sebastian Kehl and his scouting team have been tracking Lerma for months and have been in contact with his family. The 1.84-metre tall player has already made his first-team debut with Independiente del Valle.
