Arsenal manager Arsene Wenger has told Sky Sports that he finds the prospect of retiring "frightening."
Wenger has been managing since first starting out with Nancy in 1984, while he has been in charge of Arsenal since his arrival in North London in 1996.
Many Arsenal fans have been calling for the 68-year-old to stand down from his position for some time, but he signed a new two-year contract at the Emirates Stadium in the summer.
Asked if he was frightened of calling time on his managerial career, Wenger said: "Yes. Because every end is to be in front of the unknown and of course it can be a bit frightening.
"But even if it is frightening, I'm not too scared. I just want to do what I do as long as I think I can do it well and I have the motivation to do it. On that front, I have no doubt.
"After, the day will come quickly, maybe not, but I am completely focused and completely committed."
While Wenger's ultimate aims at Arsenal are likely to be winning a first Premier League title since 2004 and a first ever Champions League, he says he is on a "mission" to carry the club's "values."
"Why keep doing it? Because I love it," he said. "Because it's a job where I think you can have a very positive influence: on people's lives, on results, on the dimensions of a football club, on values -- because I think first of all a club is about values, which we forget a lot today.
"I feel on a mission to carry these values through for this club because I think this club is usually respected all over the world for its values and it carries through the generations."
Wenger's refusal to walk away from his role at Arsenal has often been put down to stubbornness by supporters, and it is a characteristic he accepts.
"I'm a guy that's absolutely passionate and I think my family would agree that I'm stubborn as well," he said. "There's always a fine line between being stubborn and stupid but if you give up too quickly in life you do nothing well."
