Promising midfielder Domingos Quina has signed his first professional contract at West Ham, which keeps him at the club until 2019.
Quina, who turned 17 last Friday, joined the Hammers in the summer on an initial two-year scholarship deal following spells at Chelsea and Benfica.
He has already featured twice for West Ham this season, both appearances coming in the Europa League against NK Domzale, and also scored a 40-yard wonder goal against Leicester City for the Under-23s in October.
Quina said: "I am very happy to have signed my first professional contract with West Ham and it has always been my dream.
"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 like to enjoy my football and do things which people are not expecting. I really enjoyed my goal against Leicester and it was a great moment.
"That was not the first time I had scored a goal like that and hopefully there is more to come.
"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 has already showcased his talents at international level for England Under-17s at the European Championship and will now aim to impress manager Slaven Bilic further and become a regular part of the first team.
Bilic added: "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 skillful and is one of those players who doesn't have to think about his first touch because it comes so naturally to him.
"He is not afraid of challenges and has skill
