Look what happened to Leicester when they upset the apple cart. Financial fair play or whatever it's called now is definitely anti competition and must be stopped.
So many examples. Wolves were another. Came up from the Championship, finished 7th, qualified for Europe, then fell foul of UEFA FFP because of a lower threshold, then finished 7th again which could have been 6th if they had scored one more goal, and then they have to be careful in what they spend.
Bottom line here is that you have to spend to compete. You have to pay big wages to attract the players who can compete at the to end. FFP makes it very difficult to sustain this. Clubs can have one or two good seasons but then they regress because the spending has to stop. The clubs with bigger revenues keep on spending to stay at the top and they are the teams only interested in stopping others joining them.
Seriously, how does a club like Leicester get relegated so soon after winning the league? That has to be the biggest example of how the elite protect each other. It's supposed to be a sport but it is financially stacked against teams who show any ambition.
