We lost 6.6k after our first relegation and 8.6k after our second. Both times that was around 25% of our fan base. Such drops in attendance are not unusual by any means. I'll happily repeat myself again and say that virtually the only clubs that have not suffered drops in attendance after relegation from the PL are those who have enjoyed a long history in the top division. There are sides who have enjoyed more top flight football than us over the last 50 years that have seen crowds drop by more than ours has.
