#7 Context
Playing both City and Chelsea was always going to be hard.
It's self-evident that City is far ahead of Arsenal at the moment. All the same, Emery needs to be given time amidst this context since it's futile to assume things can be turned around instantaneously. However, there is time to improve, and context is required.
Had Arsenal played two supposed lesser teams, such as Bournemouth or Brighton, the results may have been different. Note that many of the other top six have played "easier" teams, hence their enhanced starts.
The next game for Arsenal at this point is at home to West Ham United. Old boys Wilshere and Perez may feature, but given West Ham's issues, it could be a good time to get a win on the board.
Any histrionics or angst demonstrated at this stage, whether at the team or the manager, is surely misguided.
