I can completely agree with this, the national leagues of Africa and Asia are really organizationally and financially far below the level of European football leagues and the quality of football is low.
However, if you look at the squads of the leading African and Asian teams, you will see that most of their main players actually play in European clubs and leagues and not in the national championships of their countries.
Through the experience of playing in the strongest European leagues, African and Asian players gain important experience, undergo professional training and raise the level of their game and understanding of all aspects of professional football.
This is why it is wrong to say that if football in African and Asian national leagues is bad, that automatically means that their national teams are also bad. Exactly the opposite, and that was brilliantly demonstrated by Morocco at the last world cup in Qatar.
For the African continent, it is clear, there are many players from African countries who play with teams in European leagues. In fact, there are several names who have become star players who have played for big European clubs. like for example, Sadio Mane, Osimhem, and also many other players. Even so, I don't really know for sure how things are going in their domestic league. at least, Africa is currently doing better than Asia.
For Asia, it is true that there are many Asian players playing in European competitions. but not all of Asia, mostly dominated by players from Japan, or South Korea. the rest, not so famous.To be honest, because I come from Asia, football in Asia doesn't change much. whether it's from the organization, finance, system, infrastructure, everything is below the level of European football. Naturally, if the quality of teams from Asia is very low.
But different from Japanese football, South Korea, they have a much better system than other Asian. even if the two countries are serious about developing their football. I believe, Japan and South Korea can be much better than what they are currently showing. So, speaking of the 2026 world cup. several Asian teams that will participate in the world cup rounds later, will only be entertainment teams. I do not intend to belittle, but armed with what I know. that's the truth. however, the world cup still has a long time lag, hopefully teams from Asia will want to build up their football so that it can grow even more.
