I think you are on your own mate.As long as the results are coming our way NW can do or say what he likes.If the so called star managers do it people say its mind games and call it being clever.
NW may not want to knock the confidence out of his players others will do that for us.He may well be trying to get into the heads of visiting referees who will be more than aware of being highlighted by NW if they are not seen by him to perform well.
NW has been doing this a long time and he does not need us telling what to do.
