Wolverhampton Wanderers have completed the signing of Adama Traore from Middlesbrough on a five-year contract.
The 22-year-old's £18m release clause is believed to have been triggered by Wolves after an initial bid of £12m was turned down by Boro.
Traore, who won Middlesbrough's Player of the Year award last season, becomes Nuno Espirito Santo's fifth signing of the summer after Rui Patricio, Jonny Castro Otto, Joao Moutinho and Raul Jimenez joined during the transfer window.
"I'm so happy, it's a great day for me and my family and hopefully for the team," Traore told Wolves TV.
"I know the history of Wolves. It is a team with a big history and when people tell me I had the possibility of coming here I thought it was great. After that, my mentality is to work every day and be prepared for whatever comes.
"I think Wolves are definitely ready for the Premier League. My mentality is to fit into the tactics but I think how Wolves play will definitely suit me. Before I make any decision I know how they play, how they move, how the wingers play."
