They are the teams that have won the most number of competitions, ever. A close second is CONMEBOL, and then it's a long way to the third place and the rest.
These are the best teams, and in my mind they should be more of those countries in the tournament.
Just adding more countries with lower skill level will drop the quality.
We saw that with Qatar. It was the only team way below the quality of the tournament. The games they played were not as entertaining as the others. If we continue to add other countries that have that level of skills the whole tournament will lower it's quality.
Again and again, the same argument. I have already countered it a few times. It was the smaller teams who made world cup more exciting in Qatar 2022. Morocco managed to reach the semi-finals and Cameroon, Australia, Senegal and Japan had their fair share of upsets. On the other hand, it was the UEFA teams like Belgium and Danmark who performed pathetically during last year's tournament. I am not denying the fact that historically UEFA and CONMEBOL teams have performed well. But that is the past. Now many of these teams are declining.
