The Premier League side have signed midfielder Mario Lemina's teenage brother Noha.
The younger Lemina, who is 18 and plays on the wing, arrives on loan from Paris St-Germain.
He will spend the rest of the season with the Premier League club under the guidance of Gary O'Neil.
"Noha's an exciting, quick and direct winger," said Wolves sporting director Matt Hobbs.
"When Mario first joined, his brother had been flagged up by our scouting team.
"Mario's a driven individual, so doesn't want any favors, but he has real belief in him and thinks he's a Premier League player in the making - and Noha will back himself.
"There's no pressure from anyone here. It's a chance to look at an exciting young talent."
