Yes. It should be as far as preferred font-size of visitors and effective
color contrast promoting readability/legibility.

CD guidelines? I'm not sure I understand what this is. But, anyway, these
guidelines should not override the users' preferred font-size.

Most likely those football club fans are under 35-40 years old when/where
they do not mind small (and/or frozen) font sizes. Also, often web
designers are youngsters who do not have low vision and who prefer to have
a lot of stuff filing webpages and lots of flash animated stuff, cosmetic
effects, over-excessively driven by javascript, DHTML, etc.

Markus, I respectfully still disagree with you. I do not want websites to
create, develop, manage, tune alternate stylesheets in the name accessible
font-size and suitable/reasonable color contrast for
readability/legibility purposes. I want the normal default style sheets to
be accessible, not to override users' font-size, etc.

In order to override the users' preferred font-size, you have to code, to
add declarations, etc. In order to respect and honor the users' preferred
font-size, you have nothing to do, no code to add!

The following is one of my preferred quotes:

"
For this year's list of worst design mistakes, I decided to try something
new: I asked readers of my newsletter to nominate the usability problems
they found the most irritating.
(...)
1. Legibility Problems
Bad fonts won the vote by a landslide, getting almost twice as many votes
as the #2 mistake. About two-thirds of the voters complained about small
font sizes or frozen font sizes; about one-third complained about low
contrast between text and background.
