Sorry, but there have been protests at the game for some time now and I don't think they have affected G&T's decision to sell in any significant way.
It may not have caused them to sell directly, but it's been highly embarressing for them, and it's shone the media spotlight on the whole thing, which indirectly puts pressure on them, RBS, Broughton, Premier League, etc.
Additionally, if you had £400 million to invest - would you invest it in LFC with dodgy motives having seen what's happened to G&H? Fuck no. You'd go off and invest in a nice quiet, uncontroversial, stock and real estate portfolio which won't have 50,000 people baying for your blood on TV around the world.
We're not able to dictate terms to people with more money than we have red blood cells, but we can make it bloody uncomfortable for them if they choose to fuck us about. And at the end of the day, nobody wants to have to deal with that shit if they don't have to.
That's what the whole process is about. Instilling accountability in whoever owns the club. We can't buy them out, we can't evict them, we can't force their hand directly, but we can make ourselves a real pain in the arse.
