Chelsea away 1966, no official figures in those days and I don't think the game was all ticket. I missed that one because London might as well have been on the other side of the moon for me at that age. There was no way I could afford to go. I've seen many photographs of the City crowd that day and I'd guess at maybe 5,000 ? We didn't play the Sheffield clubs in 1966. The biggest City following at Sheffield, before the famous night at Hillsboro, was the Battle of Bramall Lane, March 1971, three days after we lost 3-2 to Stoke in FA Cup quarter final. The crowd was a record at that time for Sheffield United at over 40,000 and it was said up to 8,000 City fans were there, me included. It was a pay on the day game too with no segregation so it's impossible to know exactly how many were there.
