Europe has one advantage though, which Japan doesn't. There are a lot of young Africans in the richest European countries. These guys have the athleticism, but in Europe they are getting the conditions which they will never get in Africa. Then it's becoming possible to create a team like the French one which won the previous WC.
Even Spain started using these players. There are 3 or 4 in their WC 2022 squad, which never happened before. Italy will slowly add more and more African players. Belgium already has them, as does England. Germany too.
Also, the richest Europeans don't mind getting quality players from Brazil, which is something the Africans and Central American countries cannot afford, while Japan will refuse to do.
