For Europe:
- Some years ago I would have answered Primera División (Spain, for those who are not famililar with European football).
- Some more years ago I would have answered Serie A (Italy).
- Today I have to answer Premier League (England).
It's no coincidence that 4 out of 8 teams in the upcoming Champions League's quarter finals are from England:
Roma - Man. United
Schalke - Barcelona
Fenerbahçe - Chelsea
Arsenal - Liverpool
My home country's league Bundesliga (Germany) is still good for some surprises, but - unfortunately imo - it's clear that it also has to open to big investors to compete with the big three in the future. I wished it stayed as old-fashioned as it is, even if this would mean that the league won't make it to continental quarter finals in the future, let alone winning the titles.
On a side note:
In my opinion the majority of outstanding players will always come from Brazil. Hundreds of great Brazilian players are working abroad (the Portuguese SuperLiga alone had 130 Brazilians in the 2006/2007 season).
If Brazil & Argentina would have the financial opportunity to hold their players, they'd have the two best leagues in the world (I think their leagues are already excellent, but I don't know enough about the South American league football to judge if their current leagues are superior or inferior to Europe's top leagues).
