Part of the problem is Arteta is unnecessarily a tinker man. I understand him fixing us for one or two games when we didn’t have Tierney. But Xhaka is a liability at left back. And we lose that strong double pivot in midfield. Additionally, yesterday we kept getting systemic failures in the left with Ceballos, Xhaka, Mari. Mari isn’t a great defender, but he’s not bad. He was exposed by what was happening ahead of him.
We would’ve been better served by sticking to a traditional 4231 with most of the players in their strongest spots. Only the left back would’ve been a compromise in Cedric. And if Auba is fit enough to come on and take our best shot, start him.
