Eibar pulled five points clear of the La Liga relegation zone on Monday, as they beat Espanyol 3-0 at Ipurua.
Goals from Sergi Enrich and Pablo de Blasis either side of half time were enough to give the home side control in the game, before Charles added a third late on. The win moves them above Espanyol into 11th, while the Catalan side have now lost eight of their last nine top-flight fixtures and are just four points clear of 18th.
Earlier this weekend Barcelona were inspired to a 3-1 win over Leganes by substitute Lionel Messi, ensuring they preserved their five-point gap at the top of the table to Atletico Madrid.
