Due to the licensing restrictions on the game not all the national teams have legitimate players. This can be easily corrected by removing the file that creates a 'mask' on the effected teams. To get rid of the 'mask' go to 'C:/Program Files/Sports Interactive/Football Manager 2008/data/db/800/lnc/all' and remove the file 'fake' inc (don't delete the file) and when you now start a new game the correct squads for ALL the national teams will be available.
