Carlos Borges
The Manchester City winger is set to complete a £14m move to West Ham, where he would have the chance of making waves at senior level.
Borges has not yet played a first-team game but his performances for City at youth level have been eye-catching.
The Portuguese ace has five goals and six assists in seven appearances for City in the UEFA Youth League.
On top of that, Borges has averaged more than one goal or assist per game at both Under 17 and Under 21 level.
