Just a thought, something different. Hire the grounds of Aston manor for a live tv game and set up a fans zone. Hire a couple of big screens. Play a recording of the european cup final 82 of course. This way all fans who can't, don't want to go to the match or want to protest could watch the game outside of villa park whilst a game is going on inside. Therefor there could be 30,000 fans outside watching our finest hour and 10,000 watching the dross inside. Maybe some banners saying What It COULD Be WHAT it SHOULD BE!
Sorry if this seems insane but desperate times call for desperate measures.
