For Saudi Arabia not only do they have a pretty good performance, but also they have the advantage of playing at home since they are the host, so that increases their chances of winning the group and qualifying directly for the World Cup. As for the other team that has the opportunity to win the group is Qatar, in terms of their performance it is also as good as Saudi Arabia and again they have the advantage of being the host in this round 4. So I think Saudi Arabia and Qatar will qualify for the world cup. But this is still just a prediction, Indonesia or Iraq could come out as the group winners (only if Saudi Arabia and Qatar can play more fairly).
