Barça's defence has proved inconsistent so far this season, and mistakes seemed aplenty throughout the first half at the Camp Nou.
Approaching the half-time mark, Bilbao took the lead as both sides struggled to keep hold of the ball.
Eventually, the ball fell to Susaeta on the left side of the area. His curling cross found full-back Óscar de Marcos, who had timed his run to perfection.
Stretching for the volley, De Marcos sent Ter Stegen the wrong way and found the far corner.
