I am not having a go at OP because I do feel that there is something rotten in the culture. However, were we not supposed to have had a cultural reset with Ole when he said ' I'm gonna be successful here and there are players there that won't be part of that.' Then we subsequently sold / let go of Lukaku, Valencia, Fellaini, Smalling, Young, Darmian, Herrera, Rojo, Romero, Sanchez. Wasn't the culture supposed to have reset?
Or did we sell the wrong set of players? Will selling the likes of Lingard, Pogba, Jones, DDG, Shaw, Martial, Rashford, Matic, Fred, McT, Bailly change anything? And how do we ensure we don't end up buying another Maguire, AWB or a DVB?
I think what is badly needed is to get some competent people upstairs who can set the direction and hire people who they trust to get the job done. Otherwise we will end up with cycles of going through the same process without it leading us anywhere. Hard questions need to be asked - Is Murtough good enough or do we need to bring in someone else? What about his team - the scouts, Fletcher, Matt Judge, others in the background. The manager is the most important piece but cannot function in isolation - needs the other functions to do their job well.
