Sir Alex Ferguson claims his Manchester United successor must have experience in order to cope with major issues like the Wayne Rooney saga.
Ferguson is widely credited with playing a decisive role in persuading Rooney to change his mind and sign a new five-year contract last week.
The England striker appeared to be on his way out of Old Trafford after citing the club's lack of ambition.
The veteran Scot put the issue into the public domain during an impassioned press conference and Rooney subsequently signed a new deal following an apparent change of heart.
The 69-year-old went on to criticise "difficult" agents and has now followed that up by stressing the need for a club like United to have an experienced hand on the tiller.
"I don't think it's harder for managers to deal with – I've just got the benefit of having been at the club for such a long time," he explained.
"I have experienced a lot of things that do happen and there have been times in the past when I have gone down the same road.
"When you are the manager of our club, you have to have someone strong who can deal with all the issues and we have had to be strong over the years.
"That's why I don't think Manchester United could ever go down the road of having a young manager, to be honest with you.
"It's a job that needs a lot of experience and a lot of experience at the top end of the game.
"That's something for the future, but at the moment we have the benefit of my 24 years at the club, so fortunately that's the way we can deal with it.
"At Manchester United, you can never be surprised. There is always something happening in the club and there are always issues to deal with.
"I don't think you can deny that we got a lot of publicity that we didn't enjoy last week, but you have to deal with these situations and I think we dealt with it very well."
