Alberto Bueno has completed his move from Rayo Vallecano to Porto after putting pen to paper on a five-year contract at Estadio do Dragao.
Spanish striker Bueno hit 17 La Liga goals for Rayo in 2014-15 to help the Madrid club to an 11th-placed finish.
And the 27-year-old's impressive season did not go unnoticed by Portuguese giants Porto, who announced the deal to sign him on Monday.
Bueno told the club's official website: "I'm in a very good career stage, I can learn from those who will surround me and I have a strong desire and ambition to do my job working for a big club.
"I do not know how it will be next season, but I want to do things well and improve my numbers and my game, which is not only to score goals."
Bueno's contract includes a €40million release clause, and Porto will hope the forward can help them wrestle the Primeira Liga title back from their great rivals Benfica next season.
