Blackburn Rovers have completed the signings of Grzegorz Sandomierski, Diogo Rosado and Nuno Henrique.
Goalkeeper Sandomierski, a Poland international, has joined the club on a season-long loan from Genk.
22-year-old attacking midfielder Rosado has signed from Sporting Lisbon, while 25-year-old Henrique has joined from Academia De Coimbra.
However, all three players were not signed in time to play in Blackburn's match with Leeds United on Saturday.
