You can only "choke" from a clear winning position. It's not as if dragging ourselves to a nett lead prior to a set of difficult fixtures has ever been that. We've had worse results than a couple of away draws this season.
I do think the situation is getting to us, one way or another. Even "complacency" can be a result of that. We haven't responded to the injury losses effectively, which points to a collective lack of insight, in which Arteta is included.
But I suspect Anfield exceptionalism has been part of it, and that a whiplash to that has been part of the failure to get back on top of things against West Ham.
Meanwhile, something else is going on with Saka and it makes me uneasy, he's been off it since that reported illness prior to our win over Leeds, which also came right after that swelter of praise in the media for his performances for England. It's like he's got long covid or he's had his head turned, and we can't really have either.
