Yes, Saudi Arabia is slowly starting to buy all the best players in the world.
If they continue at this rate, in a few years the Saudi league will be one of the best in the world to watch.
It's not only that. Saudi was also pushing UEFA to let the winner of saudi pro league to participate in UCL which is crazy. I can't even imagine how big saudi pro league in upcoming years. I do believe if SPL may become as big as EPL but to be honest if saudi may taking crazy step by talking to the UEFA regarding the chance for the club to participate in UCL which is only for a club in european continent. This is why people started to said that money can buy everything.
Many people are feeling so skeptical about the latest movement from saudi club. SPL was based on asian continent and it cannot participate in UCL. It's crazy if UEFA will accept it.
I do believe 99% chance UEFA gonna reject saudi's offer to make it happen. So many coaches have been surrounding if FIFA must do something. UEFA must also try to strict the player transfer to be even stricter. Saudi club can still ruining the football club when summer transfer season already closed.
