The responsibility will always go with the manager - you put out the team.
A manager is responsible for the application and performance of knowledge.
The productivity of work is not the responsibility of the worker but of the manager.
You do hear a lot about 'player power,' but I'm one of those who believes the manager is there to take control, to be in charge.
It's up to a manager to understand his players.
It's not always the fault of the manager when a player is not performing well, I can tell you.
The managers of the big brands have a very clear responsibility. It's attracting and keeping talented people in order to sustain and build the trustworthiness of that brand. There is no clearer objective in the economy. Your economic success depends on expanding and building your economies of trustworthiness.
The job of arguing with the umpire belongs to the manager, because it won't hurt the team if he gets thrown out of the game.
As a player, when you get beaten, you can comfort yourself by saying you did reasonably well. As a manager, when you get beaten, you think it's all your fault, but 70,000 people and all those watching on television know it's your fault.
I remember the days when a footballer who had an issue in his personal life may have been told to grow up and deal with it but in 2019, that approach won't work any more. A manager needs to make sure the problem is solved, as a player will not play at his best unless he is happy in his mind and in the environment he has around him.
The manager is to be blamed who distributes parts to his players which they are unable to act.
I don't love the idea of the responsibility falling on the manager. That just adds to their in-game responsibility.
Any manager of any big institution, which is what Manchester United is, internationally, you have a role and a responsibility to give out the correct messages.
