There are two teams from Gulf and two teams from from east Asia i.e. South Korea and Japan. Instead of two teams from Gulf (normally Iran and Saudi) .. Fifa can have one team from SE Aisa because countries like Indonesia, Thailand, Malaysia are big footballing nations.
Reduce the number of asian teams. instead of that, give one more berth to south american team.Asian teams other then south korea and japan play very badly. on the other hand, many talented teams in south america other then argentina and brazil get left out
