In last few years just three Asian teams able to perform consistently South Korea, Japan and Iran relatively others are having huge difference of quality which making them problematic in FIFA World Cup, but Uzbekistan is going to be good as well because they are having good depth.
Jordan is surely going to be have not good results but still they needed to be work hard for having better results missing out of teams like China and India is surely huge setback for mega event, but sadly both countries fail to develop their structure and also have good skilled players which can bring good results for them. No doubt it's matter of shame for them country like Qatar is having chance if world cup with Iraq which is facing serious internal issues also having chance, but these big countries fail to bring good results and also have no chance of participation even now 48 countries are allowed.
Uzbekistan is the most populous Central Asian country (if I am not wrong, they are more populous when compared to Afghanistan). The demographics are tilted towards the younger generations (unlike the case with countries such as South Korea, Japan and China who are breeding themselves out to extinction). Iraq also has a very young population, and the same is the case with Jordan and Saudi Arabia. Only time will tell whether these teams will make it big in the near future.
