Espanyol were looking to add their second home win of the season against a Deportivo A Coruna team who were looking to make it back to back victories after a winless start to the campaign, but right from the off it was the home side who dominated.
Leo Baptistao broke the deadlock after just four minutes with a diving header after a smart and incisive team move on the counter attack.
That was soon followed up by a calamitous own goal as Pablo Piatti’s corner was deflected in off heads, shins and thighs and eventually found itself in the Depor net, with Alejandro Arribas getting the final touch.
Celso Borges pulled one back as the visitors struck down the left wing before cutting across the face of the box to the midfielder running in from deep, falling as he adjusted his footing to send the ball looping over Pau Lopez.
Espanyol still looked comfortable though, never really in doubt and they ensured that with the scoreline as Esteban Granero was fouled in the box, giving Gerard Moreno the chance to narrowly find the corner of the net.
The striker added his third of the season in the final minute with los Pericos easing to victory after Baptistao turned provider with a great cross to the marginally onside centre forward.
