Blackburn have signed teenage Portuguese winger Fabio Nunes from Portimonese SC for an undisclosed fee.
Nunes, 19, is Rovers manager Steve Kean's fourth summer signing and has put pen to paper on a three-year deal.
Kean said: "On the back of an incredibly busy week, we are delighted to welcome Fabio to the squad.
"He's an exciting player with clear potential and we're looking forward to seeing him push for a place in the senior squad."
Rovers completed the signing of Nunes' contryman Nuno Gomes earlier and drafted in Danny Murphy from Fulham and Newcastle striker Leon Best last week.
