Did we actually change something?
Oh, so it's like a day to day thing? "Well today I like Italy because I'm on the defensive against this poster, but yesterday I felt like attacking people all over the place so I liked Holland. Perhaps tomorrow I'll feel a little snobby and like the French, but we'll see."
Yes, there is something that connects you with the Greek NT... IT'S YOUR NATIONALITY!
Okay, so you're a gloryhunter then. At least admit that.
Because it doesn't make sense to support somebody other than your own country. I'm not going to go too far into this, but the international game revolves around... yes... you guessed it... nationality. Just like the players are required to be nationalized before playing for a particular country, the fans should have at least some connection to the country, and that means is through citizenship.
It's the only way it makes sense.
