This, I think, is the determining factor. Next season there will be 10 PL clubs playing in Europe. That will surely alter the quality of the league games which are the real bread and butter of the game. Time will tell whether the 'product' (don't really like that word but it seems appropriate here) is being watered down as players are being pushed and pushed.
Nobody in the stands to watch Chelsea Shows 3 things imo 1) the appetite for the tournament in general 2) the lack of interest in football in the US 3) the lack of interest in Chelsea outside of Chelsea.
I have addressed your point Exclude CWC teams from the league cup or the FA Cup as they are they same thing Or even both That sorts that one out can get rid of internationals too lmao
4) overhigh pricing for Tickets 5) potentially also the political situation. Given that FIFA was hoping for strong Mexican and Latin American presence, due to their proximity and taking the competition much more seriously than Europeans, the confirmation shortly before the tournament that CBP and ICE agents will be providing security and increased checks at games may have been an issue. But I don't know how much of an effect it's had a) generally and b) for Chelsea vs LAFC in particular.
