"football fans are forced to incur above-inflation rises in admission prices."

They aren't though. They aren't forced to pay exponentially increasing prices to watch (for the most part) overrated or second rate 'athletes' pout and cheat their way through matches while encouraged by rabid coaches to intimidate the officials and disrespect the laws of the game which have endured for 150-odd years.
Don't like the price of football? Go and watch a non league game. For what reason exactly are you paying big money every week or shelling out a lump sum? It isn't as if there is much by way of atmoshpere in any ground these days.
Always makes me laugh too when the price of food and drink gets pointed out.....erm, I expect you were planning to eat and drink during your day at some stage anyway, I can't recommend enough doing that before and/or after your visit to a football ground or theme park or cinema etc. etc.
Spurious claims in this article. "Arsenal and other clubs have a strong local monopoly over me and thousands of others." You can watch them online, from your sofa

I dislike being victim to 'market forces' as much as the next man but the bottom line is this is 2014 not 1914. More 'liberal agenda' rubbish from the BBC in this article. No-one is forcing you to go.
