7 Points to learn from Chelsea 3-2 Arsenal - How can Arsenal grow and develop?

#8 Ideal formation to be used against West Ham

With the aforecited points in mind, this would be a viable formation for the West Ham United game:

Xhaka has no place here since his style doesn't fit into the overall picture. He's not a bad player, but it's pretty much evident that he needs a different midfield structure to progress.

Guendouzi and Torreira must also combine and start, and Ramsey can add better-attacking balance in this context.

I would retain the same defence and Cech, as per the Chelsea game, since they need to be more organised and this will come into the fore with proper training and structural work.

Aubameyang needs to start, despite his poor form of late. Though it's time for him and Lacazette to start together and combine well as we know they can.

Danny Welbeck may be a surprise, but it's interesting to see how well he can adapt to Emery's pressing style. He clearly has the energy and pace to complement it, and he is evidently a player who can bring goals combined with work-rate.

It's interesting times at Arsenal, but let's see how things progress and develop.
