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."
