The club set up is massively important. Since Poyet we have only had one unsuccessful managerial appointment but have any gone on to be more successful after leaving?Is this a hangover from the all powerful manager? Years ago we pulled back from talking about a 'head coach' but ultimately that is what we most often have today. Perhaps Chelsea (and us - certainly me) under estimated how much the club set up affected the success of Potter.
By extension maybe Chelsea should be looking at how their set up is affecting Potter's work.
