Our decline under Carlo this season has been steady and continuous. It shows no sign of being halted. You can plot a very straight line to where it is going to end, and I'm afraid it is not in the top 4 of the PL. I don't think this team can play any worse under any other manager, from Di Matteo to Zola to Guus Hiddink. If we allow Carlo to carry on we are going to play Europa next season at best.
There is also the precedent, that whenever we have sacked a failing manager in the past we have improved overnight. But this is not my key argument. I have followed our slump in form very carefully and steadily. Yes some of our players are past their best, but I have no doubt whatsoever that what we are seeing is a coaching/managerial crisis, and not a players's one.
Ancelotti has to go now. Our chance of beating Copenhagen is not going to be any worse with a temporary manager than it is with Carlo Ancelotti.
