West Ham United have completed a deal to sign 16-year-old forward Domingos Quina.
The Portuguese won the European Under-17 Championships with his country this month and joins as an academy player on a two-year deal.
"Domingos is some talent," academy manager Terry Westley said. "He has the same qualities as a Manuel Lanzini - he is both a goal-scorer and a goal-creator. This is a potentially massive signing."
