I know there's complications in building a new stadium at the current location because of the rail tracks and canal, and more or less likely in having to play at a different location while the new stadium is being built. But could they knock down a stand each season and build it up while using the 3 other stands for the crowd?
For e.g
2022/23 - South Stand knocked down and built up. North, East and West stands operate as normal.
2023/24 - East Stand knocked down and built up. North, West and South(new) stands operate as normal.
2024/25 - North Stand knocked down and built up. West, South(new) and East(new) stands operate as normal.
2025/26 - West Stand knocked down and built up. South(new), East(new) and North(new) stands operate as normal.
2026/27 - All stands are now complete and a brand new stadium.
I think that could work.
