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.
Few African countries are dominating in soccer for years, but sadly they have never been capable of having good results at the top level due to team depth and players mentality level which feel not comfortable while they are playing against top teams of world.
If they want to have better results then surely they need to work on their structure and players development because without having strong mentality it's never been going to have changes too many players choose European countries as they feel comfortable, and their chances are also high for winning trophies. CAF is good but need more improvement with their domestic leagues also needed to be more stable in finances and have better opportunities which give them creative minds which are always important in soccer field for winning trophies.
