Of course it's important.
And it has nothing to do with formation or using wingers or youth.
It's important for any manager to know and get on with the culture of the club.
Mou brought some success but it was always going to fail long term. With Conte would have been the same.
Attacking football, long term and leader manager, mostly class managers and players rather than cnuts, should be what we are looking for since that has been mostly the formula to our success.
Chelsea for example has been the opposite mostly. Speculative football, short term managers, filled of cnuts
. And they are successful that way.
