Man United close to signing 17-year-old South American wonderkid

He's considered a world star in the making

The youngster from Paraguay who plays for Cerro Porteno in his native country is touted to be one of the most promising left-backs in world football.

The news was announced by Fabrizio Romano who reported that United are close to agreeing a deal with the Paraguayan club with the deal said to be worth $5m (£4m) plus add-on fees.

The transfer is all but done, with the final details being sealed as Jason Wilcox takes care of the move.

Agreeing on a salary for the player is one of the last things to do before an official announcement.

Still in the fledgling stages of his career, Léon has played just 19 games, scoring two goals.
