Real Zaragoza's relegation worries were heightened as they were downed 4-0 at Real Betis.

The Aragon side got off to the worst possible start as Ruben Castro's shot found its way to the bottom left corner of the net inside the first minute.

Things got worse for Zaragoza as Castro turned provider, finding Dorlan Pabon in the box and the Colombian's right-footed strike beat goalkeeper Roberto.

The second half wasn't any better as Pabon firstly put through Jorge Molina, and then scored his second to compound Manuel Jimenez's worries.
