#1 The Manchester United Model - bringing the culture back

"Manchester United is family, tradition, history, giving youth a chance, attacking football and winning." - Ole Gunnar Solskjaer
This quote from the caretaker manager pretty much sums up what he is trying to get back at Old Trafford, something that has been missing in its entirety ever since Ferguson retired.
These words pretty much epitomize the Manchester United model from years before.
As they say to get the "Culture" right and you have solved 50% of your organization's problems.
Although it is an equally difficult task to perform for someone who has not lived the Manchester United culture himself. That is probably why Moyes, LVG, Mourinho found it difficult.
They all had their models, philosophies, styles which were by no means wrong. They have all been successful managers in football. As it seems now, they were just not the right fit for the "Manchester United Model".
