I think there is a place in the city centre for a store as many tourists or locals cba with the store at the ground on match days or any other time.
Some of the ideas on here of assisting with tickets, interactive zones, 5 a side all sound very exciting and it could be like something from Niketown.
However, maybe the sums didnt add up and in fact the shop wasnt paying its way...I think with city square and the match day experience, a lot of the retail part of city is centered around that..and their online business, which of course is much cheaper in costs.
