How many soccer teams can you go for?

If you mean "International teams", you've got as much teams as officially recognized by FIFA (Football International Federation Association) : 207 teams (in august 2008)

If you mean "professional teams", it's like between 20 and 100 by country which have professionnal league (like 50)

But if you mean "teams, local like huge", nothing like France has nearly 10 000 teams (or maybe more)
