There is nothing wrong with loyalty to the nation that you now reside in. Whether born or not in Portugal.
However, we must never forget our roots. Our culture. It is richer than anyone else's, as far as I'm concerned.
I've left Portugal at a young age to the US, but I will never forget that I am Portuguese, first and foremost. What hurst me the most is what this win would have done for Portugal. Undoubtly, put our tiny nation back on the map, as it once was in the 15 century.
Than, you have team like Italy... somehow must have stricken a deal with the devil several decades ago.
Call it sour grapes...but, I am one unhappy individual at the moment.
