One you didn't address, McBain:
The English League has always been based on playing once home and once away. Even without seeding, the addition of one additional game introduces an element of chance into what is a season of skill and work.
Fulham and Crystal Palace are battling it out at the bottom. As their extra game Fulham have to play Man U. Crystal Palace have to play Watford. Any unfairness there?
Add into that seeding, where supposed top clubs are given a lifetime guarantee that they do not have to play one another in the extra game, and you increase the advantage that they already hold.
As far as writing to the clubs goes, I would think that would be a waste of time. They are all already in favour of it and, if you don't like it as a Blue, there are millions of supporters in Asia who would.
The players are in favour of it because it increases their exposure and potential earning power. The only people who stand a chance of stopping this are the national FAs.
I would imagine the foreign ones would be set against one another and, according to today's papers, the English FA bigwigs see this as a great way of getting what they want with the national team and match scheduling. Perhaps the only way to get it stopped, if that is what fans in England want, is for people to write to their local FA councillor and get some pressure from the county associations.
