Villalva, who plays for River Plate, has already been labelled
the new Lionel Messi and is attracting interest from a number of
top European clubs, including Real Madrid.
United boss Sir Alex Ferguson is planning to send scouts to
watch the talented forward play in the Under-17 World Cup in
Nigeria and clinch his signature ahead of their rivals.
Villalva, 17, 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."
Panathinaikos are also admirers of the teenager, nicknamed
'Keko', who made his debut at the tender age of 16.
