He is definitely part of the problem, I don't know if he's the main one but it's clear that the board and working process needs rearrangement. It's no coincidence that we bought and sold so many players in such a short time. Talking specifically, people like Emenalo and Granovskaia have no credibility getting involved in any professional discussion, they're club workers from different reasons, nothing more than that. In the last two seasons Jose had to sell big to buy big and in the process trying to fix the imbalance that was in the squad before him. He mostly bought replacements in response, sometimes with lesser quality with the biggest example being this season.
The moment you see a clear pattern that the manager is getting players he doesn't trust and sells them after 6 months, you know there's a real problem from people who have no qualification to do their job unless their role is a clear go and do instruction from the manager. And if that's the case, they're failing anyway as the manager was organizing and sending his report months in advance just to get random last minute attempts in the final hours of the window.
Someone needs to go or something needs to change, give the manager full control over the professional side of the game and almost as important, give the manager full support financially because he didn't get it since he came back, especially if you look at his competition. If you don't invest according to your ambitions, don't expect to magically dominate every year. Mourinho led Chelsea to the most dominant PL title in history last season while making a profit, if someone in the board got carried away and forgot the reality of the football market in 2015, they need to wake up.
