Abraham scored a stoppage time winner for Real Zaragoza during their home fixture with fellow strugglers Villarreal this afternoon.
The visiting Yellows dominated the opening 45 minutes and broke the deadlock in the 16th minute through Argentine defender Mateo Musacchio.
Villarreal had numerous chances to make the points safe after the restart, but they were unable to score a second goal.
Their failure to do so was punished six minutes from time when veteran striker Luis Garcia captialised on some hesitant defending to draw Zaragoza level.
In the third minute of added time, Spanish defender Abraham chested the ball down inside the area before striking the ball past a rooted Diego Lopez in the away goal to secure the three points for his side.
The loss sees Villarreal remain three points above the drop zone, while Zaragoza stay bottom despite the victory.
