Scandal! Barcelona denied a goal after ball had clearly crossed the line

In the 76th minute of the game between Real Betis and Barcelona a moment ocurred which could have changed everything. 

Luis Enrique's side were losing 1-0 but they were then denied a goal which would have given them 15 minutes to go in search of a winner. 

The ball was crossed by Aleix Vidal and as Neymar was about to shoot it was deflected towards the Real Betis goal. 

It clearly passed the line before it was then hooked clear, but the ball was a good metre into the goal. 

However, the goal was not given and while Barça eventually equalised, scoring earlier would have changed everything.
