When my father was a child,he thought that he had to like football at school.does it change now?Is the passion losing?
Nope. More popular than ever in terms of numbers (helpsnthat there are more people now). We are just looking for ways as a nation to not blame gerrard and liverpool for our failure at the world cup. I find its easier to blame those at fault rather than pretending otherwise.
To a certain extent the passion may be in decline. When I first became a football fan most towns in England were homogenous working class areas located around a football stadium - most fans walked to the stadium then from the immediate locality and it was normal to support your local club for life. With increased mobility, combined with many clubs losing part of their traditional support base (through urban depopulation) together with endless T.V. coverage and the present day costs of football - so the present day football crowd has changed and football is becoming more of a consumer product, with support being conditional upon success.
Sorry to be pedantic but if the question is "is the interest OF football declining in England ?" Then I am afraid football finances have become so massive that football interests have not only not declined but have increased exponentially in the last decade. The clubs are multimillion pound businesses and gave tentacles everywhere. If the OP was asking interest IN football (which I suspect he was), then I think interest in the premiership could have waned in England and certainly in other parts of the world. Global fan base for the Spanish giants and Bayern, PSG, would have increased. I think the lower leagues may have declined too (although I don't have the evidence to hand).
Perhaps the biggest problem of all is corporate tickets which are "donated" to any individual who might just be a financial benefit to the business who offered the ticket. In other words, a bribe! Its the very same "plastic fans" who Roy Keane named as the prawn sandwich clique. And thats not just Old Trafford,, the same happens at every premier league ground. The reality is, as ever, that the true fan suffers, and is priced out of the game by the corporate hospitality. Maybe that's the real reason for the decline
