Sir Alex Ferguson and Arsene Wenger both backed Kevin Keegan and Alan Curbishley's decisions to quit their jobs recently.
Within a week of each other, Curbishley walked away from West Ham and Keegan quit as boss of troubled Newcastle.
Both managers cited interference from above, and both Ferguson and Wenger hold them in high esteem for the decision to walk away.
The Manchester United and Arsenal bosses were speaking together as they were guest of honours at a dinner for the League Managers' Association Benevolent Trust and Fund.
"In the modern climate of young chairmen and very rich chairmen, you really need to be successful and you have to manage different things," Ferguson told Sky Sports News.
"I admire Kevin Keegan and I admire Alan Curbishley as they went on a matter of principle, the principle being they are not in control of their team any longer - players were trying to be sold over their heads and so therefore they walked because it is a matter of principle and I totally agree with them."
Wenger added: "The manager is the most important man at the club, if not why do you sack the manager if it isn't going well?
"I believe our [Wenger and Ferguson] luck is that we could work with our ideas, and I know if I lose a game I have to look inside as that is where I can find the solutions."
