The overall condition of Chelsea's squad is poor. At the same time, their coach could not stabilize the team. I wouldn't say that Chelsea's poor performance is only due to the failure of the coach. Their squad was also not strong enough. If the squad is not strong then it is not possible to rely on the coach alone to perform consistently well. And so the Chelsea management should try to strengthen the team by appointing an experienced coach. Chelsea management definitely needs to add experienced players to the team. Chelsea management should make a big fund to add new players to the squad next season.
Let's see how they are going to be now that Potter is out. I have always said that Potter wasn't the guy that could make this team better. All these managers that try to overreach to their positions will end up being too bad. You know what kind of manager I like when we are talking about big clubs?
Either a manager that has already managed a big club and had some success before, which would be the only acceptable thing for Chelsea right now, or a manager that is new to manager position if you want to take a risk, but been an assistant manager to someone successful for a long time, like Arteta for example. That would be the only thing that could make sense as an alternative. Not a small club manager.
