The ball was over the line and the goal was initially awarded before it was disallowed owing to Rodon being offside and adjudged to have interfered with the keeper's vision. In such cases I've seen the goals both allowed to stand and also struck off. Depends on interpretation.Wouldn't the ref have been wearing goal line tech to ping him when the ball is over the line. Seems to be that they call somebody offside based on VAR or that Davies somehow fouled the keeper
