Most clubs will sell out a derby game.......not downing your club like but i was there as an away fan a few weeks ago and it was terrible to see a lovely big 40,000 seater ground less than half full !....the attendance that day was 17,000 and 2500 of them were away fans.
14,500 fans in a 40,000 ground is piss poor by any standard.....shame because its a good club.
how many clubs outside the prem sell out for derbys ? not many, we average 20,000 for home matches which is not bad really for div 2
and your not going to get a lot turn up for the fa cup tbh
