Possibly could in conjunction with the building of IKEA and the new road layout involved.for that If not what about my other idea re hire Withdean if the price is right. give the money to Brighton Council rather than Crawley FC./council whoever owns their ground.
I think that they should improve the Academy and add a pitch and small stands to make a mini stadium of about 5000 and then play all u 23s and Ladies games there. or renegotiate the hire of Withdean.
