There is no way at all that we are more expensive to support than the majority of Premiership clubs! Not sure what they've based it on but it sounds like bollocks to me
It's quite possible because a lot of the Northern teams have reasonably low priced seats available - Blackburn, Wigan etc. You can get decent seats for £15. Man Utd have only just gone up in price since they got purchased by a debt pile. You used to be able to get adult seats for cheaper than our main stands, that's for sure.
It would not suprise me to see us high up the table. Are Bristol City moving up it as well? I think they are one of the most expensive in the Championship now.
Oh, and I remember in the close season noticing that you could get an Everton season ticket for less than some of ours as well. Might not be comparable seats as such but I suppose the teams you see more than compensates.
