Tottenham defender has been winning rave reviews.
Foyth helped Argentina to a 2-0 victory over Mexico, capping a dream month for the youngster.
The 20-year-old made his Premier League debut for Tottenham a fortnight ago and last week scored his first ever goal for the club, a winner against Crystal Palace.
If an international debut seemed early, then Foyth showed he was certainly ready.
His performance has won rave reviews in his homeland.
Argentine outlet El Liberal ran a headline describing Foyth as a 'kid who plays like a veteran'.
The report read: "If a list of the best young defenders in the world was made, Juan Foyth would be in it."
It went on, "Foyth showed an improper hierarchy of a player of his age. Beyond the physical and the technical, the young man from the city of La Plata has character and charisma."
La Nacion wrote: "The teenager's face is the perfect mask for a player with overwhelming personality."
Argentine outlet TyC Sports praised his excellence at cutting out crosses and commanding presence.
Foyth looks like a bargain for Tottenham, finally after his big move in 2017, and his patience is paying off.
After more than a year biding his time on the sidelines, Foyth is enjoying more success suddenly that he could have dreamed of.
