The 17-year-old has just made six first-team appearances for the Argentine side, but has already caught Fergie’s eye, according to The Sun.
Villalva has already featured for Argentina’s Under-17 national team.
He said: “I am calm about my future and will not let things go to my head about a move to Europe.
“I’m happy to continue playing at River Plate and want to help them become champions.”
