Porto reportedly have an agreement in place to sign highly-rated Spanish forward Alberto Bueno from Rayo Vallecano this summer.
The 27-year-old is the top-scoring Spaniard in La Liga this season – netting 16 times during an impressive campaign for his capital side.
A number of clubs have been linked with the Spaniard, but according to O Jogo, Porto have already struck a deal that will see the forward make the move to the Portuguese giants at the end of the season.
Rayo are desperate to keep Bueno, but it is widely accepted that the Spanish club could not turn down a sizeable offer for the striker.
Current Porto boss Julen Lopetegui managed Bueno when the pair were together at Real Madrid Castilla.
