Surely it’s an easy problem to solve.
Barnsley Council own 50% of the ground.
And as Sir Steve has said - if Barnsley Football Club is doing well then that will have positive spin offs for the Barnsley District.
The Cryne family own the other 50% - plus they own 20% of the football club - so obviously they want the best for the football club.
So what’s stopping these two owners offering the ground to these owners on a 99 year lease with a low annual payment ???
In that way the ground cannot be developed for any other purpose - and the present owners can then invest in the ground with the knowledge that if they sell the football club and the rights to the ground they will be able recoup their investments.
It seems simple to me - so what’s the catch ?
