Please forget stadium expansion for now , as every penny will be needed to cling onto PL status.
We are where we are in terms of the Lane.
The big chance to change it was in the 80s with plans to turn the whole thing through 90 degrees , but it didn't happen.
Then there was the chance to shunt the whole thing towards Shoreham St + allow more room at the other end to increase the footprint of the Lane end , but we hurriedly slapped seats & a roof on the Kop instead.
Then there was the chance to move the pitch towards the SS , but we didn't , so ended up with a very small capacity John St.
There is now literally no room to increase BLS or JSS.
The Kop is a poor rake , so any attempt to give a better view or more kneeroom will actually reduce its capacity.
Bolting stuff on at the back will put people miles away.
A second tier on SS will make the ground very lopsided.
So from a design viewpoint , we are limited.
From a funding viewpoint , we've just had to borrow £50m to buy the ground.
We ain't borrowing again !
We have a squad requiring constant improvement which is not cheap.
We have reduced income due to Covid.
The ground is not going to see any major changes for a long time.
In fact , I think there's more likelihood of a new stadium , if the land at the Lane becomes desirable for other purposes.
