European teams you mention, and I don't dislike them at all. In fact, after Spain, they are my three favorite teams in Europe (although the Dutch disgraced themselves in the 2010 WC Final vs Spain). So I don't think I have a bias against Northern European soccer at all.

What I don't like is ugly, unskilled, brutish, defensive soccer. This is why I dislike Italian soccer, which you'll notice is not in Northern Europe. I have also disliked Brazil, Argentina, and Uruguay in the periods in which their national teams adopted this "anti-soccer" style (Argentina in 1990, Brazil in most of the '90s and 00s). So, I'm not necessarily pro-Latin.

Germany had its great "Total Football" teams in the mid-1970s, but by the time I was old enough to follow soccer, those days were long gone. In the 1980s and 1990s German soccer was awful. And I hated that they had tremendous success in the World Cup despite this, as it encouraged other countries to adopt that style. Even Brazil eventually succumbed after the failures of their great teams in 1982 and '86, adopting an ugly, physical style in the 1990s. Basically, I blame Germany for the death of the "jogo bonito."

I will give Germany credit for lifting their game in the last decade or so. The influx of players of Turkish, Arabic, African, and Eastern European descent on the nationalmannschaft has had a big influence on German soccer, IMO, and they now play a more attractive, skillfull style than at any point since the mid-1970s. Let's hope they stick with it in the future.
