Some interesting groups there. I am not the biggest football fan, but World Cups have a certain charm to them.
The good news is: Some geography nerds count Costa Rica, Panama and other mesoamerican countries to "North America" so that would add some more. Denmark is a stretch though unless you count Greenland (which is Danish territory) as belonging to the north american continent.
As somebody schooled in geology I agree, it is just...weird to call Denmark North American because of Greenland. It is a bit like calling Britain ""South American" because of the Falklands.
