What would be the main stats to use (in order) to compare different variants of the 442 that I have created? I don't think it's as simple as finishing position, points and GD as so many variables within a season. I have focused on (in order) Clear Cut Chances For/Against xG/Gm and xGA/Gm but I'm wondering if these are the main ones or perhaps if there are others that should be included and if they're more important?
