Academy Director and Head of Player Coaching and Development Terry Westley said the Club had pulled off a major coup in securing Quina's services.
“Attracting a player of Domingos's quality and potential to the Club is recognition of the stature with which the West Ham United Academy is held," Westley told whufc.com. “Domingos spent a month training with us before heading to the European Championship finals and he has seen what we are all about, the way we work and the pathway and plans we put in place for our young players.
“Domingos is an exciting young player and he has seen that we can help him to develop and make the most of his many talents at West Ham United. He wants to come on our journey the same as the likes of Martin Samuelsen, Reece Oxford and Reece Burke see their futures here.
“Slaven Bilic personally met with Domingos during the time he spent training with us and his interest in the player and the discussion they had undoubtedly helped to persuade him that West Ham was the right place to continue his development.
“This is a big signing for the Academy and for West Ham United."
