I think Saudi Arabia will qualify for World Cup using any possible way.
They spent a lot of money to buy Ronaldo and other European players, they also become the sponsor for Club World Cup, after everything they done for football, would they accept if they're not qualified for World Cup.
Lolz..will Ronaldo go and play as for them in order for them to qualify to the world cup. Ronaldo was signed to make the league popular and for people to recognize Saudi Arabia as a football loving country. Suadi have to play in order for them to qualify and if they can't, let them stay at home and watch of countries playing in the world cup so that, they can learn from their mistakes. No country will sell their qualification tocket to Saudi Arabia.
