The capacity was probably less than 34,000 in the third tier. I am not sure on the timings of the attempts to shoe-horn a few extra seats into Maine Road but I had the impression that the home support capacity was around 30,000 at the time.
The number of visiting supporters at the time was probably not high.
I understood that you could only get a ticket with a membership card. On my visits in the mid-1990s, I always asked a friend to get the tickets.
The interesting fact is that City were enjoying better support when struggling in the second and third tier than they were getting when around the top six of the PL under Peter Reid.
