Manchester City have signed Brazil Under-20 midfielder Douglas Luiz on a five-year contract from Vasco Da Gama.
The 19-year-old completed his medical in Manchester this week and has now concluded a deal thought to be worth in the region of £10million.
A statement on City's official website said the Premier League club would make an announcement on "Douglas' immediate development pathway in the coming days", with the youngster widely expected to join LaLiga newcomers Girona on a season-long loan.
City's director of football Txiki Begiristain said: "We are pleased to welcome Douglas. He is an exciting player with great potential, and everyone here is looking forward to helping him develop his talent and progress in the game."
