Worried about Lewis-Skelly who I'm yet to see have a good performance in an Arsenal shirt, but this team is as good as we could have hoped for otherwise under the circumstances.
I thnk maybe Myles is playing to help mitigate the fact that the Rice-Zubimendi pivot otherwise ends up way too deep and has a disconnective effect on our midfield. The alternative is to drop Havertz deeper, but that's exactly when he becomes useless: he should play like Eze does, almost in line with Gyökeres.
