Chile U20 chief Fernando Carvallo is unhappy with Angelo Henriquez's move to Manchester United.
The teenage striker signed for United last month from Universidad de Chile.
"It would have been better for him to continue growing at Universidad de Chile.
"It's an advantage to have players in Europe, but the acceleration of their growth process does suffer.
"In Chile a lot of them were regulars for their teams, but over there they aren't really under consideration."
