Real Madrid's woeful defensive efforts away from home in LaLiga this season were laid bare as Eibar stormed to a 3-0 victory over the European champions.
Gonzalo Escalante bundled home a first-half opener and Jose Luis Mendilibar's men were in rampant form after the break, with Sergi Enrich and Kike Garcia on target as Madrid crumbled.
It marked a grim opening to Santiago Solari's permanent tenure as Los Blancos boss, with his team sixth in the table – now only two points above their weekend conquerors.
The loss followed setbacks such as a 5-1 Clasico thumping at Camp Nou against Barcelona and a 3-0 September reverse at Sevilla.
It means Madrid have now conceded 16 goals on the road in Spain's top flight – only Huesca at the foot of the table (19) have let in more.
