Sunderland scores goal in which the ball's path to goal was clearly altered when it struck an inflatable bouncing ball/balloon in the penalty area. The ball was struck by the Sunderland player, hit the balloon, changed course and went to the left of the GK, when the original shot was clearly headed to his right. The ref let the goal stand. Was that the correct ruling? I wouldn't know what to do had that happened in one of my matches.
