Going by the rules of the game (which I don’t agree with) the ball was probably still in play because the whole diameter of the ball was casting a shadow on the line rather than the sensible way of determining it that there is grass between the white line and where the bottom of the ball is.
Okay fine the tiniest nanometre of the balls diameter may have hung over the line, why was this one for United disallowed then?
Gabriel Martinelli has had three goals that probably should have stood, Brighton at home in 2022, Man United away in 2022 and Everton away in September
The PL actually admitted the Man U goal should have stood
