The Danes might well be :)
I dislike them as much as Chelsea for exactly the same reasons.
OK I don't know enough about FCK to comment but they are not very good outside Denmark.
Created in 1992 out of 2 train crash underperforming clubs by money men looking for a permanent revenue stream to redevelop KB's (København Boldklub) ground, which also serves as normal venue for Danish international games. KB at the time were the oldest non-British club in Europe - founded 1876.
Since then they've operated with a budget roughly 2-3 times that of their rivals, underwritten by said money men and supplemented by the profits from international games and concerts, winning 10 league titles along the way. Brøndby almost went bust 2 years ago as a result of trying to compete.
This pattern has continued until their financial advantage over their rivals, now underwritten by almost continuous qualification to the CL group stages is almost impossible to bridge.
Add to which most of their fans are arrogant tosspots who have Chelsea or Man City as their "English team"
