Hopefully, the Saudi Arabian national team will one day become an Asian football powerhouse in the future considering the amount the government is investing in the local league. The government believes that putting money into football will help grow young players who will make an impact in the global football environment.  It is still early to conclude that the Saudi government has not achieved its aim of building a strong football system, so let us give them some time. However, I think money alone doesn't lead to good performance by national teams. There are so many underfunded countries in Africa and America that still make an impact in international competition because they have so much football talent. Japan is blessed with more talented footballers than most Asian countries this might be the reason for its dominance of Asian football.
