Nottingham Forest have signed Olimpia midfielder Braian Ojeda, Olympiakos full-back Mohamed Drager and West Ham's Xande Silva on transfer deadline day.
Germany-born 25-year-old Drager has been capped 18 times, scoring twice.
Silva, 24, is Forest's eighth addition of the window and joins on a two-year deal for an undisclosed fee having made two senior appearances for West Ham.
"Braian is a signing who will give us valuable competition in the central midfield area," manager Chris Hughton said.
"He has a good profile as a young player who is keen to progress in the game and is an important addition to the squad.
