In 1979 we were one of BRITAIN'S PREMIER CLUBS now look at us. Everything about us is suppressed and small time and our "fans" really don't help they just harm the club but they just cannot see it.
In the 1978-79 season, when we finished 3rd in Div 1, our average attendance was 26,702, with a highest attendance of 35,166 (v Villa) and a lowest of 17,499 (in the penultimate home game against Southampton). There were 9 clubs with a better average attendance than us. In descending order they were:
Manchester United
Liverpool
Arsenal
Manchester City
Everton
Tottenham Hotspur
Aston Villa
Nottingham Forest
Leeds United
The following season we averaged 22,735, with a lowest of 11,735 v Bolton. That season, there were 16 clubs with better average attendances than us, 4 of whom were in Division 2!
Consequently, I'm really not sure what point you're trying to make about our support at that time? The 1978-79 season was an exception rather than the rule. The golden era for us attendance-wise was from 1947 until 1959, when there were only 3 seasons where we averaged less than 30,000. Even in the season where we had our best ever average of 38,819 (1949-50, when we had our highest ever league attendance of 60,945 v Wolves), there were 12 clubs with better average attendances.
We've currently justifiably acquired a reputation for playing the most dour and unadventurous football in the Premier League, yet people are expecting new fans to come flocking to watch us if the capacity was increased?
