But all this fuss about the SuperLiga is only because UEFA is afraid of losing the monopoly of the football market in Europe.
Take, for example, this "friendly" competition (Which is not organized by UEFA or FIFA.):
https://en.wikipedia.org/wiki/International_Champions_Cup
It works similarly to SuperLiga, clubs enter by invitation.
You're gonna say it's friendly. It's true it's considered a friendly tournament.
But the term friendly is very subjective, it will depend on the importance the clubs give it. If this friendly tournament has more money than any other official competition, which one do you think the clubs will try to win? It's the "friendly" tournament.
The problem is that the quality of soccer suffers hard with more competitions and more pressure on the player's physical condition.
If you look at the international competition, the nations league, frankly speaking I am not even watching it. I even forgot that Portugal won it. That is what happens when you have more competitions. The quality interest goes down. Let's see what the next, the so called conference league brings to the table. I am skeptical that many will watch it next year.
