Name another professional football club any where in Europe that can only cater for 3.3% of its conurbation and that of its immediate catchment, say a 10 mile radius without competing with other professional football clubs?
There isnt any and if there was it would soon be rectified.
Sixfields is not fit for purpose in its present state, all these non league clubs you refer to, dont have the same issues that hold us back.
You seem to have forgot to tell me the names of the "most non league clubs now have corporate boxes". You defeat your own argument every time by stating something as a fact when everyone can see is incorrect.
I'll wait for the list of those non league clubs
