Talking about Asia the only great teams are Japan and South Korea (and maybe Iran), for all the others is valid the same thing I was saying about the African teams: one edition they could be great, then they miss the next one.
That was very accurate for the African teams especially Nigeria, Senegal and Cameroon. They have good players in Europe that selected their national team to represent, they have good qualities when they play in CAF and at the early stage of the World Cup but once they advance, they just fail badly and can't resist. I say, they are playing good for once or twice at best then failure for a decade before getting on feet again.
It's true, many great players come from Africa, but no national team has the depth of their squad, with talented players in every position. I think that's why African countries often fail at the World Cup, especially when they reach the knockout stage. According to the FIFA rankings, Morocco, Senegal, Egypt, Algeria, and Nigeria are currently among the top five African national teams. As we know, these teams boast star players from elite European clubs, but one or two star players aren't enough to lead a team to the World Cup trophy. Morocco journey in the last World Cup was, in my opinion, impressive.
