It makes sense what you said
Speaking from the economic point of view and the interests of FIFA / UEFA, it is not in their interest for Croatia to be a champion for example
We fans really like to see teams that are not favorites, being champions or ending in a good position in championships
But FIFA would make much more money having a champion like Germany, Spain or England, than Croatia.
Exactly, because the country that has been in the game longer earns more, not only the football association of that country, but also the entire economy of that country, considering how much the fans in those countries spend during the time they support their team.
It's sad to hear this, I don't live in Europe, so there are things that we only learn about via TV or internet
If the conditions are not that good, the whole Croatian team deserves even more for having made it this far.
The president of UEFA was at our main stadium last year and here is what he said:
"We have been talking about this for a long time, with President Kustić, now he is a little more concrete. But governments and local areas must help with that. The stadium is shameful, especially because one of the stands is closed. It is a miracle that Dinamo in such a stadium achieves excellent results. We give all football associations a penny for infrastructure. In Slovenia, for example, UEFA provided 80 percent of the funds for stadiums.
SourceIn the last years the team that is most talked about, apart from the ones that are already world champions, is Belgium, but if you analyze the results, Croatia has been better.
And finally, I think Croatia has the best chance at the moment to be Nations League champion. The title is within reach, it is possible to beat Netherlands and it is also possible to beat Spain or Italy.
However, if you look at the odds at most bookmakers, you can see that they (again) gave Croatia the least chance of winning the first place, and they even set the Netherlands as a big favorite in the first game. This is a sample from our local bookmaker.
