Im not sure whether moving mid season whas ever a consideration. As I remember it, it was just a notification that we would be moving in the new season. I mean, I wasnt alone in thinking that it would have been near impossible to have moved at that time amd had they got everything done, even in a shortened timescale, then we may have had like 2 months at the new place, with about 3 games.
Hadn't it also been stated that it was always in their plan to removed the pitch that was laid for the test events. That pitch was never fit for PL level football.
