Referring to the Mourinho scenario, O'Neill said: "In the case of appointing a director of football, I am sure the owner of the club would ask me and of course I would say 'no'.
"If the owner has the sort of relationship where the manager is allowed to do what he wants, that is the only thing a manager can ever ask for - to be in charge of affairs. That is the way I've tried to work.
"If I thought there was some sort of interference I would acknowledge that I wasn't overly pleased with it.
"But you have to earn the right (by) doing well at the football club."
