Marc-Andre ter Stegen has apologised to his Barcelona team-mates after the goalkeeper's mistakes helped Celta Vigo record a dramatic 4-3 victory at Balaidos, preventing Luis Enrique's men from going top of LaLiga.
The champions – who also lost at Celta last season – fell three goals behind in a dreadful first half that saw a poor clearance from Ter Stegen contribute to the hosts' opening goal through Pione Sisto.
