Eibar moved four points clear of the relegation zone with a comprehensive 5-0 victory over 10-man Real Betis at Ipurua.
Jordi Amat’s own goal in the sixth minute proved a sign of things to come for the visitors, who failed to produce a shot on target all night.
Gonzalo Escalante doubled the Basque side’s lead on the half-hour mark, heading home unmarked from six yards out, in another show of lax defending from Quique Setien’s men.
Aissa Mandi was dismissed 10 minutes into the second half after dragging down Charles inside the penalty area, with the striker netting the subsequent spot-kick.
Charles soon doubled his personal tally to put any remaining doubt over the outcome to bed, while Sergi Enrich added a fifth with 10 minutes remaining.
Eibar had only managed six goals in their first 11 League outings, while Betis now have the second worst defensive record in the division.
