Worth remembering when you say the aj bell is the next step for sale that their preferred option was to build a new stadium in sale, which they couldn't get planning permission for.
The aj bell isn't a bad stadium, but imo the problems with it stem from how difficult it is to get to by public transport.
I've not been to Moor Lane, but if it's more accessible for Salford fans, it could be worth the downgrade in stadium.
A worry is that salford haven't been able to afford the rent at the aj bell, and the proposed solution seems to include the council owning Moor Lane and Salford renting.
