Good summary Chimp, it's definitely well worth a watch for those who haven't seen it yet.
I don't think it gets overlooked per se but in amongst what goes on, on the pitch, it's not until you stop and think that you realise just how much investment has gone into the infrastructure over the last few years.
The EPC being the obvious one and even that's being constantly upgraded and also, by the sounds of it, trying to make it a base for the youth team as well, or at least make it a better environment for them. A full rip up of the SB pitch, new drainage, spinkler system, electronic advertising boards, Legends Lounge, Exec Boxes were done as well, additional seating, the SW rebuild, the fanzone, ticketing systems, new ticketing area, refit of the Club Shop at SB, a new Club Shop in the City centre, and I think all the toilets are being/have been done through the Stadium as well? Probably other bits that I've missed!
