The “hydration” breaks and extended halftime is the uniquely americanization of the sport, and I hate it too. I don’t foresee it coming to club football any time soon.
BUT if/when the European super league happens, then I think it’s inevitable. By that point, I will have likely fallen out of being a dedicated fan of watching pro football.
All the other aspects mentioned in OP are not americanization though. Arguably more accurate to call it European, example being 1934 World Cup in Mussolini’s Italy. Commercialization has started long before Americans got involved. Corruption has existed on all levels of football. Anecdotally, a friend of mine who played in Greek’s 4th division basically had to lose a match because there were police waiting for them outside the stadium in case result didn’t go the “correct” way.
But to contain this geographically is also a mistake. Can’t even blame this on the West. Russia’s oil tycoons’ ownerships and sponsorships have been in place, paired with Gulf states’ indirect ownership. China’s short stint at club football investment with buying out players to play there, and then followed by Saudi Arabia’s method of doing the same.
All this said, I’d argue that the problems in football reflect the problems with the state of geopolitics and world finance capital. Until that changes, I don’t see how football as a whole changes.
