Athletic club scored a stunning opening goal from the half-way line as Barcelona's keeper went walkies.
Ter Stegen made a hash of doing a 'Neuer' during the Spanish Super Cup clash, when he came out to head the ball away. The clearance went straight to Mikel San Jose, who took no time to control and volley over the stranged Stegen.
It certainly wasn't the German keeper's finest hour...
