Let me preface this with the confession that I was the one person who supported the Super League.
But hot take and this in not a likely prediction or anything, but very much a hot take.
If a major change in the football landscape is incoming it’s the fifa club world cup gaining relevance. I say this bc if Saudi Arabia can have 6 teams stacked with top players and a decent league around that you have another massive league, meanwhile Qatar and the MLS are attracting top players too.
If there can be 5 Non European leagues which have 2 teams that are UCL level an expansion would make sense.
But if that happens, quality players will be spread across even more leagues and the bottom half teams across the European clubs will get worse and worse, clubs like Werder Bremen, Rayo Vallecano, Empoli cannot compete at a decent level in such a world.
Best case scenario, the domestic season becomes an 18 game season with 10 teams in the top division with the fifa club world cup in whatever way its formatted being the primary revenue generator for top clubs.
This could make the UCL either another competition or it could make it the lower tier competition. Perhaps smth like the Euros even.
I disagree based purely on the distances involved. A global league has too much travel, so the games would be limited. That limits the revenue. An 18 game season is also worthless and wouldn’t be accepted by anyone but the top teams.
You are basically asking for the Super League but with non-European teams, since no league would agree to this, with the added laughably bad idea of an 18 game league season.
Yes the distance is an issue. You can play midweek games in the continent but globally it might be difficult.
Well you coud have 15 teams and a 28 game season, its still a 10 game reduction for every club. But also, the top teams are the one with the power, they are the one who influence the boards and FAs.
