Claudius we had a chance to solve for this in the summer. We didn't. While you can explain away the precise circumstances of this season in footballing and coaching terms, you can't on the squad building front. You can't stop pushing the boat out in this business if you want to challenge with any predictability.
You will point to Liverpool, but they are in the same spot. Their squad is fragile. Even more reason to have addressed our own issues! They went through a big managerial shift, we should have known exactly what to do, and we fucked around instead.
