Wolves have signed Portuguese right-back Nelson Semedo from Barcelona in a deal that could be worth £37m.
"It isn't often that we have the opportunity to sign a world-class player from a world-class club," said Wolves chairman Jeff Shi.
Semedo, 26, has played 124 times for Barca and won 13 Portugal caps.
Barcelona said the deal is an initial 30m euros (£27.61m) plus 10m euros "in variables".
When asked why he chose to join Wolves, the defender told the club website: "Last year they did a very good season and it's a very important team in England, in also Europe. I hope this year we can do very good things.
"Coach Nuno is a very good coach. He did very good things here in Wolves, and in other teams too. For sure I'm going to learn a lot from him."
