German term (edited): Begeisterung bis zum Rausch

When Cole signed a four-year contract in July, it was greeted with enthusiasm verging on ecstasy by most Liverpool fans who were convinced that his capture represented the first marquee signing of the new post-Rafael Benitez era.

not euphoria, because football can be as cruel as it can be kind
not frenzy either, as not all fans are knife-wielding lunatics

For your first occurrence:
Choreography of the masses: The sport, the stadium, the passion (i.e. forget the preposition 'in')

I am also tempted to translate 'Begeisterung' as 'support (for your team)', because this is what fans/supporters do, i.e. it is not so much a love of the game/spectacle per se as a devotion to the team that they follow.

It seems to me that you have a problem with the 'im + noun' triplet here.
'in the sport' (though for football, I would prefer 'game')
'in the stadium (or 'ground')
'in the ecstasy/euphoria/frenzy'
English calls for an indefinite article or no article at all here, thus upsetting the balance of the title. That's why I would recommend omitting the preposition altogether.
