I don't know if that included me, but motivation is (amongst) what we have been lacking for a long time, at least it looks that way to me. We have nearly always put in a good shift against Arsenal, but too many times we have shown signs of complacency and lack of effort against so called "lesser" teams, even in the late 90's when we were tinkle poor ourselves. Even Harry couldn't get that completely right, the times we turned a goal against into victory says more about our team's sheer skill than proper motivation and focus. IMO.
When that is said, we have to assume that when you bring in a professional footballer (not into the youth setup), he has a certain skillset which you need, and that he knows how to kick a football. What you need is a direction to follow, a system to fall back on, and drilling into said framework. You don't employ a carpenter for an insane amount of cash and then have to show him how to hold a hammer. The notion of paying a footballer 50-100k a week (or even 225k) and then having to coach him how to properly take a free kick, a corner or show them where the goal stands is ludicrous. And if so, keep Freund out of it.
To me, it seems like we nurture individual skills more than giving our players directions how to react to different scenarios and stages of the game. Of course I don't have anything else to base that on than that we look severly dependant on individuals performing (or being fit), or else the entire team falls apart, individual mistakes notwithstanding. You need to be told what to do - not how to do it, motivated to do so, and you need the practice and confidence to be able to do it. If not, practice in your spare time or take a severe paycut (not realistic I know).
That is why I despite being in full support of Harry, have great faith in us bringing in a more tactially minded manager and the coaches he prefers.
