The disillusion with football, for me, is mostly for the money involved. Football was a working mans sport - all you ever needed a was ball, and jumpers for goalposts. And now, the top players and clubs are so out of touch with the roots of football that I just feel I shouldn't support it anymore. I will, and do, support it - I just don't feel like I should.
Even choosing to follow a different club - a lower league club - the aim for all of them is to get to the top!
I agree that it might be time to just find a new passion, or invest more time in playing sport myself, rather than watching it!
