The 65-year-old has been at the club for 21 years.
Fergie told The Sun: “I have no date set for retiring.
“At the moment I am enjoying being at a football club with fantastic footballers.
“I enjoy watching them play so I have no need to retire. I tried to give myself a target to retire some time ago and that was a mistake.”
The Scot added: “When you get to my age you have to consider your health. And as long as my health is good I will continue.”
