The binman chronicles
Player Valuation: £80m
Surely the City of Manchester Stadium / The Etihad was exactly the same scenario? Hosted athletics for one summer and then they took out the track?
They only had what is the middle tier on the main stands above ground before they dug down creating the lower tier you see today. They also had one end missing to allow the space for the track.
Sounds like we will have a temporary stand or one that retracts. Search this thread for commonwealth games, you will see it's been discussed to death with possible solutions.
