I don't think the Saudi league is very important, it's only heard about with transfers and that's it, personally I haven't heard anyone watching the Saudi league, it's a useless league for me.
I hope Sacha Boey will do well there, he contributed a lot to Galatasaray. I want Boey to be successful.
They've got good team set up and he definitely would learn more with them. Normally, the rate for his purchase was low considering how advantageous his skillset is but the country of play also has an effect too. Which is why the bid no matter the amount, as long as it's something tangible would be accepted. SPL wouldn't have been a good option and the best decision move to Munich was made which is actually all that matters.
