Wow. You're way out of touch.
This is probably the biggest victory in Grimsby's entire history. They will morally be the winners of this tie no matter what happens. Kicking them out would be a punishment far, far, far exceeding the severity of the "crime", ridiculously disproportionate. And you want the proud institution of Manchester United to pursue such punishment? It'd be like a school bully kicking in the teeth and stealing the lunch money of a little kid in the schoolyard, just because the little kid was 1 minute late to the exam but got a better score than him. I'd be embarrassed to associate with the club if we did this.
