I think mate, that if you look at times when other clubs managers/officials have spoken out, and not only in football but other sports too, when they've been wronged, that there is evidence to support that a well-honed public statement or two, not tirades, has worked in preventing further wrong doings.
Is it just me ? I see nothing wrong in fighting your corner and standing up for yourself and your team, especially when you have been wronged as many times as we have.
What would some people on here prefer us to be, a doormat ?
