Butwhy 2 countries?!My country is small and organized the euro 2004 all by itself!
Yes you are right, but Switzerland is much smaller than your country. You can see the difference by comparing the total area of both countries. The total area of Portugal is 92,391 km² while the total area of Switzerland is 41,285 km². Also, it happened before in Euro2000 (I guess it was in Belgium and Netherland)
