Is demanding they be sacked "scrutiny"? 'Cause to me it just sounds reactive. The manager sets the terms, the staff work to them. Glibness aside I find it hard to hold Mpurinhos reign against anyone other than Mourinho. Ole, I can perhaps see more of the other side, but Carrick to me has shown some astuteness this week in stabilising the absolute Trainwreck we've been on the field (though I know others disagree).
As I said upthread, if Rangnick is truly this wizard, then let him work out what he can get from them and their usefulness.
