The Frenchman, in his 15th season in charge at the club, still trails Ferguson by ten years in terms of his tenure.
However, the 62-year-old insists that he is more interested in beating the Scot as opposed to outlasting him, ahead of United's trip to the Emirates on Sunday.
"[Ferguson] will manage until he dies and I think he will be 100," joked Wenger.
"My motivation is to beat him. To last the longest is not a record. Of course I will never beat his record. But to win the game on Sunday is my motivation.
"We have to consider that we are in a job where we need our physical strength and health. That weakens, I've heard, the older you get."
Wenger arrived in North London in 1996 after stints in France and Japan.
