So I have not really enjoyed the football of the last 3 matches as much as I enjoyed our pre World Cup football. I think it is worth trying to rationalise what Arteta is doing before dismissing it.
Last year we played a 23 at the back, Partey central. Ben White kept wide and Zinchenko came central. Partey had a tendency to naturally occupy right half spaces, so this balance worked. If you took last year’s team and just replaced Partey with Rice, this is the problem you would see: Rice occupies half spaces on the left, the same as Zinchenko. The point of Zinchenko moving centrally is to drag the opposing right wing in and leave Martinelli isolated with the opposing right back. With Rice out there, you’d likely get traffic out left and disable this dynamic.
So what Arteta did in response, was create a system that allowed both Partey and Rice to occupy their respective half spaces. And in the process isolate both Bukayo and Martinelli on either flank. What you see on attack is a system that very quickly gets the ball up to the final 3rd and keeps it there…
