I think the Newcastle thing is a bit harsh they were in a relegation battle last season and now find themselves in the champions League positions and in decent form overall. I read a tweet saying that from their last 38 games Newcastle have 76 points so they are in pretty good at churning out results.
I can't believe they thought they would necessarily be as high as they are this season. So they are trying to take every point and one point away at arsenal for them is pretty good all things considered.
They also identified how Brighton got blown away especially Martinelli had consistent space and they shut that down and threw the challenge back to us as to how do we overcome that.
As frustrating as it is for us how that played they set up to get their result and it worked and we have to find a way to overcome that in future.
Arteta has mentioned the squad will be needed if we want to navigate the full season so we know that we need to be able to have some other options which we just don't have or don't want to use.
