Manchester United manager Sir Alex Ferguson says modern management is so precarious it is "impossible" to predict who could replace him at Old Trafford.
The 71-year-old Scot, who has been in charge at the club for 26 years, plans on staying in the job for another "two or three" years.
And he says it is too early for United to consider a successor yet.
Ferguson said: "There's no-one on the agenda, I can assure you."
"I'm hoping to stay on for a bit of time anyway."
