Porto are closing on a deal for Rayo Vallecano striker Alberto Bueno.

Bueno comes off contract at Rayo in June.

O Jogo says a deal has been reached between the player and the club, coached by fellow Spaniard Julen Lopetegui, one of the biggest supporters of his signing.

The forward is the top Spanish scorer in La Liga with 16 goals so far and fifth overall in the fight for the Pichichi award.
