West Ham youngster Domingos Quina has signed his first professional deal.
The midfielder, who was on Chelsea’s books before joining the Hammers earlier this year, is now under contract at the London Stadium until 2019.
He turned 17 on Friday, enabling him to be signed on professional terms.
“I am very happy to have signed my first professional contract with West Ham and it has always been my dream,” he told the club website.
“I chose West Ham because it is a great club and they like to give young players opportunities to break into the first-team like Reece Oxford, and I hope to do the same.
“I know that talent alone is not enough to see me develop as a player and I just want to keep working hard every day. Hopefully I will get my chance.”
Quina was born in the West African nation of Guinea-Bissau before moving to Portugal as a child.
He was with Benfica before joining Chelsea.
West Ham manager Slaven Bilic said: “I am personally delighted with the news. We know a lot about him and he came away with us on pre-season.
“He is one of those players that you think if he doesn’t make it, then which player will?
“He has got everything and it is now down to us and up to him how much he is going to improve and dedicate his life to achieve something that God gave him.
“There is no doubt he has something exceptional. He is skilful and is one of those players who doesn’t have to think about his first touch because it comes so naturally to him.”
