Great question, and was wondering the same. Was listening to the Chesterfield v Bromley game on Radio Sheffield yesterday, and on final whistle their commentators were saying 70K-80K. Think they were slightly carried away with the occasion though and not as level headed as our commentary team remained
Seriously though we could take 30K (think we took about that for Bradford play-off when we were attempting a return to the top flight) but considering our home attendances are much higher than that season and given the quality of football we have been playing, I'd like to think we could mirror that. Surely anyone who made the effort to go then would do the same - you would think.
