The club should sort out cheap tickets and advertise them EARLY for this. Let season ticket holders bring guests for free even.
I paid good money for my season ticket this year but I don't really care about selling cheap seats.
It could be one of the biggest games in this in this years championship. And loads will tune in on the friday night to see if newcastle continue their freefall.
Get a bumper crowd in and that'll be good for sales next year maybe.
