The Manchester Arena used to boast about having 1000,000 visitors a year and the profit was around £5 per visitor.I would imagine the various shirt and stadium/campus sponsorships will be split off at some point. The arena will be an absolute money printing machine, especially if we also have an involvement in associated infrastructure eg hotels, food and drink outlets etc. Could even be a training kit or sleeve sponsor if not the main shirt logo but would make sense to integrate it in some fashion
It isn't big business, unless it is some world wide group owning a load of them under the same brand it would make zero sense.
