Wolves are hoping to agree a fee for Olympiakos winger Daniel Podence, who is valued at more than £20m.
Manager Nuno Espirito Santo is targeting the 24-year-old as he looks to bolster a squad that has played 39 competitive games this season.
Podence has been capped by Portugal at all age levels bar the senior team.
He joined Olympiakos from Sporting Lisbon on a five-year-deal in 2018 after he terminated his contract with the Portuguese club.
So far there has been no agreement over a fee.
