West Bromwich Albion have completed the permanent signing of Matheus Pereira from Sporting Lisbon.
The 24-year-old forward spent last season on loan at the Baggies and has signed a four-year contract. He topped the Championship assist tally with 16 for the season.
Pereira triggered a permanent move for £8.25m in June after making his 30th start of the season as Albion secured their return to the top flight.
West Brom's sporting and technical director Luke Dowling said: "While there has never been a question that Matheus was our player we decided to leave the final details until the season was complete.
"We wanted Matheus to focus on his football and the last nine games of the season. We agreed out of mutual respect, between club and player, to finalise his contract in the close season.
"Everybody is aware of the impact he made in his first season and from speaking to him I know he is now very excited by the challenge of playing for Albion in the Premier League."
