Just a thought, but I wonder if one of the reasons we have refrained from sacking Ange is because we want to convey an image of stability to prospective signings.
If we had sacked him before Xmas, all the players we were talking to would have opted to go elswhere if the manager they had been speaking to, suddenly left. Because Ange would have obviously been telling these players how he sees them fitting into his plans etc
I am not saying it's the main reason but I definitely think it's an important consideration. I believe the club have probably earmarked mid to late January as the decision on Ange's future.
By then it will be clear to everyone if he has managed to change our fortunes, if he hasn't we will be in a relegation battle and the club will have to sack him. We will have played Newcastle, Liverpool, Tamworth, Woolwich, Everton and possibly even Toffenheim.
If things haven't markedly improved, and by then we should have any new signings through the door, the club will be able to sack him without it affecting our transfer business.
And I do think the clubs priority right now, is to bring players in, above sacking Ange. It makes little point if he goes this week or in two weeks.
