Arsene Wenger turns 60 next month but insists he "does not believe in retiring" and will stay at Arsenal until his physical strength gives out - or he is given the boot.
Wenger admitted he started out in management with the plan of only working until he was 50 but now says life without football is unthinkable.
Wenger, speaking at a League Managers' Association conference in London, said: "I don't believe in retiring unless you have to. I have never had a day when I think I could live without football."
He added: "I know one day it will happen but you shouldn't live every day knowing you are going to die - you live knowing that you want to live."
Wenger admitted it can become too physically demanding in old age to remain as a football manager and that when the time comes he is sure others will let him know.
He added: "In our job you need physical strength and to be a bit of an animal to convince people it's important to win.
"But once that physical strength goes it's a handicap, although you can compensate to an extent with experience.
"But you need in some way to be an animal and you need physical power.
"You will know if you are not hungry enough any more but other people will tell you if you are not good enough any more.
"It's not for a manager to know - it's for other people to know and to tell him."
