Wolves have completed the signing of Girona defender Ladislav Krejci on an initial loan deal.
The 26-year-old centre-half, who can also play in midfield, will complete a £26m permanent move until 2030 once certain clauses are met.
The Czech Republic international moved to Girona last summer and made 35 appearances in all competitions as they finished 16th in La Liga, surviving by a point.
He joined the Spanish club from Sparta Prague, where he spent five years and won two league titles.
Wolves, who have lost their opening two Premier League games, have already signed full-backs Jackson Tchatchoua and David Moller Wolfe and forwards Fer Lopez and Jhon Arias this summer.
