On radio 5 on saturday, it commented on wigans poor following of less than 1,000 for the everton game.  I would be surprised if it is a 1,000 for our game especially on a sunday. 
Could be 16,000 especially with salzburg just 3 days before.  If I had to chose one, I would choose £15 for potentially exciting uefa game over £30 wigan game, not that I expect a huge crowd for the uefa game.   
I think rovers need to admit they have got it wrong and scrap cat a games with the exception of liverpool and Man U.  Possibly Newcastle as well if they are doing well.  As a season ticket holder who gets a really good deal, it would not bother me.
