Martin O'Neill believes football is in the age of the "disposable manager".
And the Aston Villa manager insists he is "not fire-proof" despite the success he is enjoying this season with Villa third in the Barclays Premier League and into the last 32 of the UEFA Cup.
O'Neill said: "I think for a number of years we have been in the age of the disposable manager. I really do. I don't get paranoid about. I do get concerned about it. I am not fire-proof. You have to win football games to become fire-proof."
He added: "That is the nature of the game. You must try to keep on top of things so forgive me if I didn't get carried away by people telling me Villa would go third if we won on Saturday (at West Ham).
"Nothing surprises me in the game anymore but then I've held that view for quite some considerable time.
"I don't think managers are being given a decent crack of the whip. It is getting harder and harder for young managers trying to make their mark.
"For example Paul Ince (at Blackburn) hadn't had much chance to bring in players he would feel comfortable with and to have his own team. It seemed as if he was in the job three minutes.
"The fear of relegation is part of it and you are not getting much of a chance and being judged purely on results. I accept we are in the results business.
"But 14-15 games doesn't seemed a lengthy time to find out about your reserves, yet alone the first team."
