Although there was no obligation to do so, Borussia Dortmund have given Leonardo Balerdi − the 19-year-old youngster signed at the beginning of the week − clearance to take part in the South American U20 Championship in Chile. "We're happy to grant his request," said sporting director Michael Zorc on Wednesday.

Balerdi will be part of the Argentina U20 side drawn in a group with Paraguay, Ecuador, Peru and Uruguay. The group stages will be concluded on 26 January.
