Giovanni Trapattoni accepts that he may be out of a job if Republic of Ireland fail to beat Estonia, but the 72-year-old does not intend to retire from management whatever the outcome.
Ireland go into the first leg of their Euro 2012 play-off in Tallinn on Friday as favourites to progress, and Trapattoni - whose side were controversially defeated by France in the 2010 World Cup play-offs - knows the pressure is on to deliver.
Asked if the games against Estonia could be his last in charge of Ireland, he said: "Yes, yes, but I am not nervous about this because I know football."
Trapattoni has now spent the best part of four decades in management but he has no intention of walking away from the pressures of the profession.
"I was talking the other days about standing on the edge of the cliffs - that's our life, it's a manager's life," he said. "Our life is dangerous. I have a habit of looking down on dangerous situations - but I think I will live, if not here, then maybe there is another. I don't know where, but sure, I am not stopping here."
Trapattoni has claimed Ireland should not be considered favourites for the tie.
"People say we are favourites, but I don't think so. I believe we can qualify, obviously, but we have another 180 minutes and only after this can we say that we deserve go through, not before.
"I am an optimist because we have only conceded one goal in the last seven games. Our performances have always been good, so I am confident.
"I have always said, without arrogance, that we deserve to be where we are. Since the last qualifiers, we have improved the team and we are proud of the job and what we have given the players.
"We must think about this 180 minutes of our lives, the management, the players, the Irish people. I will be very proud if we achieve qualification because this is the meaning of our jobs."
