Because some of us actually care more about the spirit and traditions of the game than to engage in tribalism and blind devotion. Hell, Gary Neville was furious at the club and that guy is more Manchester United than anyone on this forums.
Good point on UEFA being unable (or unwilling) to punish clubs for breaching its own rules though. They're not going to do anything, aren't they?
I don't give a toss about the continental clubs. Seems like some of their fans support the Super League idea in some type of form. It's understandable when you consider their financial situations even. They needed the money.
But I'd like to see the English clubs get punished in some way because if they don't, what's stopping them from throwing their pram out when things don't get their way the next time?
