See I don't really get this attitude.
Empty seats on tv can not be seen as positive in any way.
Not for the Club or owners and investors.
Top flight football relies on huge sponsors, partner investmentsite etc. You need this to compete at the top.
Etihad should be full every week it really should. I suspect this is a reason why Family stand expansion seems to be on hold.
It's not just about match day tickets sales income, the big money is from sponsors and a full stadium is more attractive
As for leaving early, WTF is that about really.
Going to the match is not a chore or like work to bunk off early, savour every minute.
