Rayo Vallecano have continued their terrific season with a 3-0 home win over Real Betis.
Emiliano Armenteros scored his first goal since returning to Nuevo Vallecas following an unsuccessful six-month spell with Sevilla.
The 26-year-old midfielder beat the offside trap in the 51st minute and raced through the middle before cooly finishing past Fabricio.
Vallecano doubled the lead after 75 minutes as Diego Costa headed home from an in-swinging Roberto Trashorras free-kick.
Raul Tamudo sealed the win in stoppage time by sliding the ball between Fabricio's legs from an acute angle.
