Why not build it on the Clanage?
It's already a sports ground so no TVG issues there, it's next to a railway line (OK the line needs upgrading but a least it's there), it's on the new tram/bendy bus route. It's surrounded by allotments so just buy a new plot of ground for some old gardeners. Bedminster cricket club could play on the all new Ashton Vale village green. Sorted.
