I've heard of this tournament before but didn't really delve into which teams were joining in, and FIFA is too much of an obscure competition now is it all about the money?
I won't be watching this match - Watching Flamengo's match along with other matches, people will probably focus on the league matches.
If I had to guess the last match it's probably PSG vs Flamengo because it's predictable. lol
This new league certainly won't be very interesting unless FIFA offers a lot of big things to improve this league, I myself am not really interested in watching it, the aim is good, it's just that FIFA doesn't yet understand what its orientation is for, if it's for money, like what you said, that's very bad, it's not increasing the community's potential and love for football.
However, if this tournament becomes very official and becomes a world recognized league like the World Cup, it will be very big indeed and a lot of money will definitely come into this space, there will be a lot of sponsors too because the market is very wide, not only on one continent, it should only be that FIFA has to expand the football confederation to every other country, currently there are only 6.
