You might want to amend the article to note that there is discussion at the European level about establishing a minimum percentage of players on a team who are nationals of the nation for which they play.

But this is nothing new. In the US, how many atheletes were born in the community for which they play? I went to the University of Kansas and how many professors were actually from Kansas? At the international level, Qatar and some other nations essentially recruit and purchase new citizens to play for them at the Olympics. I recall a German who won a gold medal, I think, ostensibly for Spain. He did not even know how to speak Spanish or what the national anthem was. What is the percentage of nationals that serve on corporations with a certain nationality? IKEA is actually a Swiss/Dutch corporation as far as I can tell.

Also I disagree with the statement that Europeans don't display their flags. I live in Holland and there are far more people here with a flag pole - even poles sticking out from apartments - and who display their flag at any excuse. I was surprised at this when I first moved here, but I then noticed the same in Switzerland when I was there. My Swedish friend dutifully raises his Swedish flag in the morning and lowers it at night, every day!

Trends appear to be at their most extreme when they are nearest their extinction. I would venture to guess that nationalism, as we know it, is effectively dead. At least among those who can choose which country to go to.
