Nicolas Castillo scored the only goal as Chile held off Argentina 1-0 in their Under-20 Sudamericano clash.
The 19-year-old Universidad Catolica star headed the winner in the 22nd minute after a well-flighted free-kick from Bryan Rabello.
Castillo was lively throughout the game, showing off several pieces of skill that emphasised the talent he possesses.
In the tournament’s other game on Wednesday, Colombia needed a solitary strike from Jhon Cordoba to defeat Paraguay 1-0.
The Under-20 Sudamericano, also known as the South American Youth Championship, is being held in Argentina and is fought out by the Under-20 versions of the South American national teams.
