I think the main issue TH is that our stadium and the surrounding routes are an absolute nightmare to get in / out of, in particular a work day.
Also yesterday their was another train strike so thus this meant additional cars on the road.
Manchester's infrastructure and transport is a joke and is getting worse year by year. This is not the club's fault but I know from speaking to a lot of fans that they reluctantly shun some midweek games as they are not getting back until very late and have to get up for work early in the morning.
I am hoping to get a season ticket next season but not sure whether I would want to go to midweek games for the reasons above.
I don't think it's people not wanting to go it's just all the chaos, inconvenience and ball ache of navigating through a traffic clogged congested city.
