"The difference between Chelsea and ourselves is that they have changed their management structure three times recently," said Ferguson.
"The longevity I have means I can take the long view all the time.
"I can look three or four years ahead. Managers coming into other clubs do not have that time."
It is the main reason Ferguson has successfully been able to halt Roman Abramovich's seemingly unstoppable march towards silverware, to such an extent the Russian seems to have fallen out of love with the game.
Abramovich will not be at Old Trafford for Sunday's title crunch, although Ferguson feels the Chelsea owner still has plenty to contribute.
"He seems to have had less impact than he has had in previous seasons but that doesn't mean he is bored," said Ferguson.
"From what I know of him he enjoys his football. It has become a big part of his life."
