Well, there is a side over the road that can't afford a new stadium either, and they don't want to waste money upgrading what they have now because it will take mega bucks to make any real difference long term.
SO
Both clubs ground share, halve the cost, means only paying half the upkeep of the stadium, make the thing huge, fill it with corporate, alternate pitches (to keep them playable) and build it to be a venue for international games. As it stands now the city comes first, when we are home they are away, wouldn't mean that much upheaval and the long term benefits could impact both sides in very positive ways. Might also help heal some of the divide and acrimony between both sets of supporters. Would be an awfully nice time to see Merseyside at the top of world football again.
(And if the 'haters' don't like it, they don't have to come along for the ride - they won't be and have never been missed anyway!)
