#4 Emery's touchline presence
It's unfair to say that Wenger never was active on the touchline. However, Emery definitely is more direct in giving instructions from this position.
At the Man City game, he was near constant at the touchline in delivering instructions. The Chelsea game was no different.
This shows a change in attitude and the attention to detail that was lacking under the latter part of Wenger's tenure. This isn't to knock Wenger at all.
However, it was self-evident that the team needed more guidance and structure. It looks like Emery is the man to deliver this, but patience is desirable in this case.
It will take time to implement what is desired, and cannot be a quick fix.
