Top level sport depends on the perception, real or otherwise, of uncertainty.
Celtic’s problem is twofold - a vast majority of their games carry no perception of uncertainty, and they’re locked into a system which condemns them to being also-rans at European level.
They do carry a certain cache due to their history and support, but are only used as a stepping stone by players.
Only the derby games and the European qualifiying games in August carry any significant degree of uncertainty.
The increasing NBA-isation of association football is a huge problem.
European club football has decimated club football elsewhere in the world. The Brazilian and Argentine leagues, for instance, are second rate now because none of their best players remain at home. The World Club Championship used to be a genuine 50-50 contest, now it’s a procession.
The top five European leagues (and it’s really the top two, because three of them are barely hanging on) have decimated all leagues outside of these.
Within almost every league, there’s a vast wealth inequality.
Celtic and to a lesser extent Rangers in Scotland.
Bayern Munich in Germany.
PSG in France.
Juventus in Italy.
Barcelona and Real Madrid in Spain.
Ajax, PSV and to a lesser extent Feyenoord in Holland.
Porto and Benfica in Portugal.
England is a sort of outlier because of its dominant economic position, and yet it isn’t, because inequality within English football has never been greater.
The thing that has always driven capitalism is growth and potential growth. I think late stage capitalism is where it has always run into problems because wealth inequality becomes entrenched to an irreversible degree and monopolies, oligopolies and cartels rule. Association football is very much at the stage now where monopolies, oligopolies and cartels rule, with little hope for anybody outside of these.
