Manchester United manager Sir Alex Ferguson said it was "scandalous" for people to suggest he should retire.
Ferguson celebrates 20 years as United boss on Monday
Ferguson, who is 65 on 31 December, will celebrate 20 years as United boss on 6 November.
"It is scandalous some people think I should retire. It is none of their business," said Ferguson.
"Some people in this country don't want to work, so I don't think you should decry anyone who wants to. It disgusts me that people think that way."
Ferguson is the most successful manager in British football, with his trophy haul including eight Premiership titles, five FA Cup wins and the memorable Champions League triumph in 1999.
But the Scot said the manner in which United had achieved success gave him as much pleasure as the trophies themselves.
"You are going to be judged by trophies," he said.
"If you don't win, you are not going to be here for 20 years. I am proud of what we have achieved here. It has been an incredible spell and hopefully we will win more things at this club.
"But I also feel the way we have done it has been good.
United must have had more top players than any other club in the country
"It has been the right way, the Manchester United way. We have not changed in that respect.
"Sometimes we get carried away with our attacking instincts but you may as well die in a glorious way than not."
Ferguson also paid tribute to the quality of players he has had at his disposal during his two decades in charge.
Ferguson has worked with international stars including Bryan Robson, Eric Cantona, Peter Schmeichel, David Beckham, Roy Keane and Ruud van Nistelrooy.
"Supporters who have followed this club for 50 years are very lucky people because we always seem to produce someone who can light up the stage," said Ferguson.
"We have had players who put themselves on the canvas of artistry long before I came.
"Manchester United must have had more top players than any other club in the country and, in that respect, I have been very lucky to work with some of them."
