Sir Alex Ferguson intends to carry on as Manchester United manager for at least two more seasons.
Ferguson believes Queiroz (left) is capable of succeeding him
"I'll be here for at least another two years. I couldn't be enjoying the job any more than I am now," Ferguson told the Mail on Sunday.
The 65-year-old also tipped his assistant Carlos Queiroz to take over when his reign, which began in 1986, does finally come to an end.
"He is capable of doing the job," insisted Ferguson.
"It's not my role to say who the next manager is going to be," said the United manager, whose team still have a chance of repeating their famous 1999 treble this season.
"But what I would say is Carlos has the qualities to manage any top club.
"I wouldn't like to say he should be manager because I don't want to put pressure on anybody.
"But he's intelligent and experienced and knows the game inside out."
Manchester United are currently top of the Premiership and are still in the Champions League and the FA Cup, with both competitions at the quarter-final stages.
"You can't help but enjoy it with the team we have the way we are playing," said Ferguson.
"We have done everything the right way and there is fantastic spirit in the club."
