Yeah i think they should add all the 205 teams in FIFA 2006, but if they do that most will probably have no licenses and probably will screw up the clubs.
However if they don't all them i think they should consider these.
-AFC: South Korea, Japan, Iran, Saudi Arabia, Bahrain, Kuwait, Iraq, China and Uzbekistan.
-CAF: Tunisia, Morocco, Cameroon, Nigeria, Senegal, Mali, Egypt and South Africa.
-CONCACAF: Mexico, United States, Costa Rica, Canada, Guatemala, Jamaica, Panama and Trinidad & Tobado.
-CONMEBOL: Argentina, Brazil, Chile, Colombia, Peru, Paraguay, Uruguay, Bolivia, Ecuador and Venezuela.
-OFC: Australia, New Zealand, Fiji and Solomon Islands.
-UEFA: Italy, France, Russia, Spain, Portugal, England, Czech Republic, Netherlands, Switzerland, Latvia, Denmark, Greece, Sweden, Germany, Bulgaria, Croatia, Belgium, Ukraine, Turkey, Romania, Scotland, Austria, Norway, Ireland Republic, Finland, Slovakia, Slovenia, Northern Ireland, Poland, Belarus, Serbia & Montenegro and Israel.
