Barcelona is demanding for goal-line technology to be used in La Liga after they were wrongly denied a goal in their 1-1 draw with Real Betis on Sunday.
Betis had taken the lead in the second half through Alex Alegria. Barca thought they had drawn level when Aissa Mandi attempted to clear a Jordi Alba shot off the line.
The goal was ruled out by referee Hernandez Hernandez, but replays showed the ball had completely crossed the line.
