Barcelona B scored three times after half time to overcome Real Zaragoza in this evening's Segunda Division encounter.
The two sides went in level at the break after Eldin Hadzic cancelled out Jean Marie Dongou's 36th-minute opener just before the break.
Promising youngster Dongou restored the hosts' lead two minutes after the interval before Gerard Gumbau edged them further in front in the 62nd minute.
Joan Angel Roman completed the rout not long after, with Barca now on six points from their opening two games of the season.
Zaragoza remain winless after drawing their first two fixtures of 2014-15.
