That is shocking! I mean even if the goal line technology is having an extended holiday, how on earth does VAR not step in? Clear and obvious error - doesn't get any clearer!
Even the pic above doesn't do it justice - the keeper actually held the ball against the back of the post!!!!
Maybe as robfosters says going into the side netting caused the problem.
Usually they go straight to HawkEye view and show the computer generated version of the ball. The fact they have still yet to show the HawkEye view shows something isn't right with the tech.
