I’m new to PL (only 4 years) and women’s football (8 years). But when I first heard of this rule I thought it was reeeeeeallly weird. There’s nothing like it in most US sport. It seemed such a random way to determine the better team. But within a year I completely embraced it. Many top notch European teams have a much stronger home field advantage, and it made sense that a goal scored away in that environment should hold more weight. So, oddly enough, it disappoints me UEFA is getting rid of this rule I thought was random and going with 30 extra minutes or PKs.
