West Ham have completed the signing of Portugal Under-20 forward Mesaque Dju.
The 19-year-old joins the Hammers on a free transfer from Benfica having agreed a three-and-a-half-year contract.
Dju is seen as a player for the future at the London Stadium and will initially link-up with West Ham's Under-23 squad.
He said: 'I know a lot about West Ham because it is a very big club in England and helps young players get to the first team.
'I want this and I'm working for this. I want to help the team and I want to score a lot of goals for this team.'
Dju was part of the Benfica squad which reached the 2017 UEFA Youth League final and were crowned Portuguese national U19 league champions for 2017/18.
