Mirth From a professional point of view it could be argued it is a developing league and you need top people to go out there to bring the quality and standard up. I don't think Saudi will ever be self sufficient and always be a league propped up by the government.
I think if you're a top player and you go out there in your peak years that is different. Towards the end of your career I can see why. Inzaghi is 49 years old, he'll come back as a 51 year and still have 10-15 coaching years ahead of him.
For players as well, they have such a short period of time to make big money and a lot of these players have come from poor backgrounds where they view money differently.
