Attendance 1 - the number that paid for a seat...whenever they bought it, like STH's.You are all over the place.
That picture shows less than 1/4 empty at the very most...so if that applies to the whole ground...the crowd would still be over 40k...which is complete rubbish.
Massive massive red flag on this poster.
Attendance 2 - those who actually turned up.
Attendance 2.5 - however many City choose to say...for whatever reason...are there.
Edit; nothing new - EFC were doing similar 50yrs ago...allegedly
