Great idea. Just in this case, the second round of qualification (global) will be a kind of world championship for weak teams. And I would love to see how, for example, "average" teams in Africa play against similar teams from America, Europe and Oceania. It would be super interesting. I think everyone is tired of watching the teams constantly boil in the same cauldron of confederation tournaments.
Surely it's very good and acceptable idea, but it's not easy for anyone to do this all because this need very long process and some good hassle for FIFA and other Federations as well with we already have very packed leagues seasons and very small window for International matches it's not easy to do this all specially when we are going to have covid19 issue around us, and it's not going to leave us normal in long term basis. Still, very good as we will have some tough competitions and many new teams will also have some chance to quality for next round with have equal basis chance against good teams.
To be honest, I do not understand such reasons "it's difficult." It turns out that FIFA wants to hold the World Cup every two years and it's not difficult (although this is complete nonsense), but is it difficult to make logical transformations? I think it's a matter of desire. From a business point of view, such changes will be beneficial to everyone and will greatly increase the interest of viewers in the qualifying matches.
From my point of view, the world cup is something precious. As it comes once every 4 years, it has a meaning to people.
Generally, the team wins the world cup, is the best team and that's the way it should be regardless of the players that team has.
Now imagine that the world cup happens once every 2 years then it didn't have that type of importance to anyone. And people have passed a lot of difficult times before, and I don't see any reason to suddenly make the world cup happen once every two years. Seems like money is never enough for FIFA, is it?
I agree, I am not against a business trying to make more money, however it is incorrect to do so by diluting the quality of the product they are offering, expanding the number of teams that qualify to the world cup should be more than enough, after all it is not as if soccer fans can watch all the games anyway as that will require a huge effort.
But holding the cup every 2 years will lower the impact of winning the world cup in a significant way and the prestige of the competition will go down, something that is undesirable no matter how we look at it.
