FFP rules determine how much money a club has to spend on its team. So, the argument "Oh, it's because xyz money, blah, blah, blah" is meaningless.
The richest club in the World is......
?? Manchester United. Who lost at home to WBA at the week-end. Man U. playing the drabbest football ever, given the opposition. WBA are relegated because they are s***e - yet, suddenly, against Man U., they play like wolves. Why, because somewhere (new manager bounce maybe) they have played to win.
To be fair, Man United are second. Man City, PSG, Barcelona have all spent the most in their respective leagues and are all league champions... so it's hardly meaningless.
WBA won with barely any possession, less shots on goal - but that's football, and that's why we'll be at Sixfields on Saturday thinking we can beat Plymouth.
