Aston Villa have completed the signing of Netherlands international Anwar El Ghazi from French side Lille.
The 24-year-old winger, who spent last season on loan with Villa and scored in their play-off final win over Derby, has now signed a four-year contract.
Villa head coach Dean Smith said: "Anwar proved to everybody at Wembley how good a player he can be.
"He's ready for the step up to the Premier League. He's a young player who has an awful lot of potential."

Smith is confident that El Ghazi, who is a product of the Amsterdam academy at Dutch giants Ajax, can be made even better, after scoring six times in 37 appearances in Villa's promotion-winning season.
"It's now my job and the job of the coaching staff and Anwar himself to fulfil the potential that he undoubtedly has." said Smith. "He'll be a great addition to the squad for next season."
El Ghazi is Villa's second signing of the summer, following last week's addition of Birmingham City forward Jota.
