With a fit squad they were still losing matches they should've won this season. This is a trend that began last season and it hasn't stopped.How is it naive? With a fit squad the system has worked to a decent degree. Add the fact the squad still needs preferred transfers in some areas, it's no wonder it's not working out.
It was a mistake not to add better centre back depth. The midfield is still ad hoc with discipline issues and the attack is generally alright but lacks depth so the players are feeling it with the match load.
