Bulls for the Football League!
I have favourites only in the UK; couldn't imagine myself supporting any Spanish or Italian club, and the German, Portuguese and French clubs just don't do it for me at all either.
In England, and in general, my number one club team ie the one I follow the most closely (as closely as possible without actually ever seeing their matches) is Hereford United FC: a traditional club from western England near Worcester, which unfortunately were relegated from the former Third Division (nowadays League Two) in 1995 or 1996 and have been playing in the Conference ever since... now three consecutive seasons they've finished second in the Conference, making it to the promotion playoffs, but twice before they messed their hopes up in the semi-finals. This year it'll be different! Edgar Street to host League football again!
Apart from HUFC, I follow the deeds of a few other clubs: Luton Town (Championship, former First Division), Cardiff City (Championship as well), and lately also the fan-founded AFC Wimbledon (Ryman Premier, err... 7th highest level?). From the bigger clubs I fancy Manchester United, but my passion for them has dimmed a great deal since the magical 1990s crowned by the Treble in 1999.
Then, outside England, it's Aberdeen (Scottish Premier League) from Scotland. The club's not been in its best shape for years, stuck in the mid-table with some bloody Caley Thistle, but I've always been fond of the Dons anyway.
Even though I've never really 'changed' my favourites in club football (no way I could do that), my international team opinion is even clearer: Germany has always been the number one for me. Völler, Klinsmann, Littbarski, Matthäus, Möller; they're the heroes I remember the best. Oh yes, and even though Zico was a bloody awesome player back in his time, Brazil is the one team I hope not to win the upcoming World Cup (mainly because I find it devastating to see one and same team winning twice in a row).
The World Cup '06 will unfortunately write some new history for me, having only Germany from the teams I favour involved... to name three, Cameroon, Denmark and South Africa all failed to qualify.
