Wdym get your eyes checked? You can literally watch any game at the Etihad and see it for yourself.
The simple fact of the matter is, Domestically, City are not a big club. Clubs like Liverpool and United have 10-15+ year waiting lists for season tickets, Meanwhile City literally give tickets away to social media influencers just because there is so many empty chairs. This is not some meme, this is not some conspiracy, It just is what it is. When we went to the Etihad, in the peak of a title race, Entire sections of the terraces were empty. That is not the sign of a well supported club.
The simple fact of the matter is, The Majority of Cities fanbase is just plastics from the US / India. In actual England, They are dwarfed by the likes of Villa.
