Eibar have beaten Barcelona B 2-0 in the Segunda division this evening.
Alain Eizmendi scored for the visitors after 56 minutes before Jose Luis Morales added the second with six minutes remaining.
Barca B have now lost four of their last five matches, and face Numancia next Saturday, while Eibar entertain Real Zaragoza.
The loss leaves them teetering on the edge of the relegation zone as they sit 18th with 13 points from their 11 games this season.
