Espanyol's 26-year stay in LaLiga is over after they suffered a 1-0 loss to Barcelona in a derby that saw both teams reduced to 10 men.
Luis Suarez's second-half strike consigned Barcelona's rivals Espanyol to a 1-0 defeat and relegation from LaLiga in a match that saw two red cards.
Espanyol knew anything but a derby victory at Camp Nou on Wednesday would relegate them to the second tier for the first time since 1994.
They were given hope when substitute Ansu Fati was sent off five minutes after coming on at the start of the second half, only for the numbers to be swiftly evened up when Pol Lozano was also dismissed.
