The best part is that it doesn't matter who the manager is. They thought Moyes was the problem, then it was Van Gaal was the problem, then it was Mourinho and now it is Ole. They have spent several hundred million on players, wages and pay offs and still nothing has changed.
The whole club needs to be rebuilt and no one in the world has the power to do that. It requires a whole system change like we had with Txiki and Ferran at City and they won't do that as they think they just need to get in a new person on the touchline.
Long may it continue.
