I wouldn't replace Curle yet. He's only had 13 league games this season and though the results have not been as good as we would have hoped he needs to have the opportunity to get the performances from HIS team that get us back on an even keel by January (at least as many wins as defeats) and a clear plan of what he needs to do in January to kick on towards the playoffs/promotion. Thomas needs to back him if he gets us to January as hoped here.
The team needs to show they are behind the manager.
A good Cup run will help.
A significant reaction from last Saturday's humiliation would be an indication that optimism isn't entirely misplaced.
I wouldn't replace Curle yet either. He should be given the season, or the bulk of it at least. He certainly should be given enough time that he can put his best team out, something he has hardly been able to do yet because of injuries.
What would be the point in letting him rebuild the squad and then sacking him after just 13 matches? It would be a crazy decision IMO. Give him until spring.
The league is very tight and a couple of good results will see us shoot up the table.
