’Liv Football’ won’t work like Liv Golf, least not in the UK. Too tribal unlike golf which is individual - even if all the ‘best‘ players sold their souls, football here would survive. Would be some sort of correction in terms of finances over time, but the league structure wouldn’t change. There’s a big distinction between owning a club in England and players actually going to KSA to playThe Chinese Super League wasn't sustainable and their government put and end to it didn't they?
The difference with the Saudi League is the Saudi's could fund it and throw bucket loads of cash at it for 100 years if they want. They've already got some of the best players in the world and bought numerous top European clubs and sporting leagues already.
Saudi football would be the domain of plastic fans in Asia etc
