Wigan have done zero to promote this game or anything about this World Cup really. It has been really dissapointing and they aren't the only club to be like that.
Even as a Wigan fan I'd be loathed to give anymore games to the DW. It's a decent enough stadium but because it's not owned by us, I don't think the club really care about the internationals being here.
The one thing I will say about it though is that it's not just Wigan fans responsibility to fill the ground tonight and if it isn't the blame (if anybody thinks there should be some) lies at all fans doors.
