This is the first time we see three countries hosting the world cup and 48 countries the world cup, we should wait for 2026 to see the result of the decision of FIFA, I know it can decrease the quality of the 2026 world cup so I'm not a fan of the increasing number of the teams but in the same time it will increase the community of the world cup by letting three countries host the world cup and it can have benefits in the other hand.
The level of the World Cup has long lagged behind club football, and in fact we will see interesting games starting from the quarterfinals. Although this bunch of participating countries and a bunch of host countries creates an atmosphere not of a serious competition, but of some kind of carnival. From the point of view of entertainment, it's probably cool - but only if you go there live, but I won't watch most of the games of this tournament even for money.
I think manager issue is the biggest issue there and we need managers who run both club and national team to make that happen again. Because we see managers who only manage national teams, and those guys have like maybe 10-20 games a year at most, whereas club ones have like as much as 60 depending on which teams manager they are.
So national teams do not really pay that well, plus managers don't want to sit at home for 3 months to watch their players in clubs. If we can convince people like pep to manage Spain, or Mourinho to Portugal etc etc, while managing the club as well, that would be a good idea for sure. I think it would bring a lot of success to national teams, and more fun as well.
