You need to look up the definition of counter productive. It means: in trying to improve a situation you can inadvertently make it worse. Which is exactly the type of thing that could happen with the mentality of appointing somebody like AVB.
It's already been pointed out to you that using a narrow and highly selective time frame of win ratio means nothing over the long term. Otherwise can we presume that you'd be advocating us replacing Wenger with Fat Sam ? (now where have I heard that before ..... ?) Or Ronald Koeman ? (who you said had a terrible record as a manager)
This idea about us producing 0 and so can't decrease productivity below this level is utter nonsense. We are in the Champions League every season and we won the FA cup last season. Our productivity could quite easily fall away. To then extrapolate this idea of 0 productivity giving us an excuse to hire and fire without any consequences simply beggars belief.
You then go on to say you don't care who we hire, don't care who we sign and don't care who we sell. But you just want some progress. Forgive me if I'm missing something, but I think your approach to securing this progress is negligent at best and clueless at worst. Like I said, I'm not opposed to change but it has be a change that will improve us. This idea of change for the sake of change and to hell with whatever change that might be is totally ridiculous and as I said, highly likely to be counter productive.
