Nailed on within 5 years.
R.I.P. football as we once knew it.
There was talk a few years ago that the new American influx would lead to 'franchises' being uprooted and playing some 'home' games in different stadia across the world.
They tried to introduce the phrase "Manchester United at Norwich" etc to describe away games.
The relative lack of financial clout of the Americans meant they couldn't see it through. Being fragmented, the owners also lacked an overarching philosophical reason for doing so.
The Middle East oil nations have both the clout, and the reasons. In spades.
Like you, I think football as we know it has ceased to exist following last years World Cup, and what we are seeing is just the start.
