The fans are the ones that make the character of the club. They create the atmosphere.
To give a different analogy, if you were up for a good night out then you’d put on your best clobber, make sure all your mates were out, even the ones that were skint (because you’d sort them out), you’d have a good skinful and have a great time. As long as the night club, pub or person’s house wasn’t a total dive, you’d have a great time and wonder when you could all do it again.
It’s nothing to do with the stadium, sorry, ground.
If we were away fans visiting the Etihad, we wouldn’t stop singing.
Atmosphere is not painted on the walls!
