Completely agree with what you’ve said, there’s nothing quite like 12 defeats in a row to a side to give you zero confidence even when you whilst not in control seem to be nullifying the opposition.
And it’s only in hindsight you can look back and say, yeah Arteta got it right…he clearly had a game plan and it worked
I also agree with your remarks in regards to Raya, and definitely if Arteta has decided on him to be the number 1 you hope that his antics in the first half are an outlier rather than a sign of what’s to come. I was open minded to him even though I like Ramsdale, but I really haven’t seen any evidence of him being any better and I think Ramsdale can feel rightly aggrieved.
I remember years ago thinking it was harsh on Eboue when we bought Sagna, but it only took a few games to realise that he was a massive step up, but this not been the case with Raya.
And yes, this is exactly the kind of result you want going into the interlull. A result that makes you excited and impatient for more Arsenal games.
