All I’m going to say is let’s see. You’re probably right though. But the new North stand does give City the opportunity to look at, evaluate, and possibly relocate the away fans. (as well as home fans)
What I will say is, there is little or no away support or noise from the away fans at Spurs, Arsenal, and Liverpool, who are shoved in the corner, near the corner flag. Whilst at United, Newcastle, Everton, Villa, etc, you always hear the away fans because they are mostly in the upper tiers. That’s where the vast majority of the away noise and away support also comes from at the Etihad.
