If the quality was so high, then the following outcomes were not possible in Qatar 2022:
1. Australia defeating Danmark (1-0)
2. Japan defeating Germany (2-1)
3. Japan defeating Spain (2-1)
4. Morocco defeating Belgium (2-0)
5. South Korea defeating Portugal (2-1)
On all these instances, European (UEFA) teams were defeated by teams from AFC or CAF. The days of European dominance in football is over. The sooner you realize it, that much better for you. Else you will continue to lose bets on these teams.
I agree that European teams are stagnating while other nations teams are getting better. As an European, I find this good because it will bring us more good games in the World Championships. But if you look at the world champions, other than Brazil and Argentina there is no nation outside Europe that have won the World Cup since Uruguay in 1950. Every nation (including the top European nations) can lose a game or two. But we will see if your words that European dominance is coming to an end will come true.
I would not say that the quality of football in Europe is falling, but in fact the quality of football is increasing every day on all continents, due to better organizational and financial conditions for football in many nations, and thus the difference in the quality of teams from different continents is decreasing.
However, the best football is still played in Europe, both national team and club football, and Europe still invests the most in football.
Qatar is the first world cup after 2002 in which the European national team did not win, and in club football we continue to see the dominance of European clubs at the world club cup.
I think it is too early to conclude that European football is stagnating or declining.
It's one thing to beat a European team in one game, and quite another to win an entire tournament.
