Absolutely.
Based on the way they govern, it's probably a safe bet they want a controlling stake.
What with the global demonising of Oil, and the push to greener futures they realise their tap of money is going to dry up somewhat, so better to funnel that enormous pile of cash into another revenue stream, what better than the global #1 sport of football.
They already own or have stakes in the biggest clubs in Europe and are buying more, now having their own league is a natural progression.
However with that said I'm skeptical of the future and success of their newly invented league, bit like the Chinese league, football has deep history in Europe and South America etc, it's a tribal game, families are divided over it, blood is spilt over it, it has taken many years to become the beast it is today.
Simply inventing a new league with teams means sod all if there's no history and reason to support other than some aging star names on the team sheets. No one wants to watch games in empty stadiums, and culturally there's a huge difference between Europe clubs and their vision.
How many European teams have global fans that relish the idea of getting the full match day experience of going to the ground and a pub before or after etc, people travel round the world to watch premier league games and experience this, you won't get a similar experience with their new found league.
