Argentina U20 coach Javier Mascherano is delighted with what he's seen from Manchester United attacker Alejandro Garnacho.

The youngster was Argentina's outstanding player at the Toulon Tournament this month.

"Alejandro is a great player, with a lot of potential to continue growing," said Mascherano. "It is clear that by playing in the club he plays for, and above all the importance his club gives him for the future, will depend on him for what he is capable of."

Garnacho recently scored four goals at the Toulon Tournament, helping Argentina finish fifth.

He also won the Revelation of the Tournament and Goal of the Tournament awards.
