Well, influenced as in Utd having an advantage due to the power base / connections their manager has built up over the years, that I agree with. That is normal, you can find it in most workplaces, maybe Stein and Shankly also used their influence for their clubs in their day. It comes with success.
Influenced as in the league favouring Utd subtly weekly to maintain the sheen of the brand, that I find far-fetched. When something under our control, such as our strikers finishing better and wide players providing better penetration would have meant we would just be a few points off them now.
