I've no problem whatsoever with folk raising concerns about what has gone wrong/what is going wrong, Alan. What I don't think is particulalrly helpful is immediately looking for someone to blame. Too often these days, and not just in football, when things go wrong the first comment some people utter is "heads must roll". I'm sure most of us have been the victim of such thinking or comments at work at some point. Much more positive and sensible is to analyse what has gone wrong and how to put it right as quickly as possible.
