Barcelona head coach Ronald Koeman admitted he is worried about the stuttering club following their equal worst La Liga start.
Barca equalled their worst tally of La Liga points after six games since the Spanish competition reverted to three points for a win following Saturday's 1-1 draw at 10-man Deportivo Alaves.
Antoine Griezmann cancelled out Luis Rioja's opener with 27 minutes remaining to salvage a point for Barca, who have just eight points to already be as many points adrift of defending champions and bitter rivals Real Madrid.
