Wolves are signing permanently Willy Boly from Porto.
O Jogo says Wolves will pay the €12m settled with Porto to make Boly's move permanent.
The defender played a key role in Wolves' Championship triumph and Premier League promotion this past season.
Boly was a first-choice for Wolves boss Nuno and played a key role in their success.
The 27 year-old is tied to Porto until 2021.
