Ferguson is ready to let his players do the work themselves, knowing if the powerhouses of England and Spain fulfil their immense potential, it could be an all-time classic.
"You had a feeling that night in Barcelona and obviously there was fate attached to last year as well," said the United boss.
"That happens. But I think this type of game might be beyond fate.
"It has the capability to be a fantastic final."
Merely by electing to wear white shirts, Ferguson had to answer comparisons with the last team to face Barcelona facing such a colour, Real Madrid, who were promptly beaten 6-2 in their own Bernabeu backyard.
"That wasn't a defeat, it was annihilation," said Ferguson, before adding pointedly: "We are very happy playing white and we are better than Madrid!"
United have proved their strengths at home and abroad all season.
Their performances may have been lacking some of the sparkle from 12 months ago. But they have developed a tenacity and refusal to yield that might well come in handy tomorrow if they find themselves in the rare position of facing opponents who dominate possession.
"Neither team will want to give the ball away," he said. "That will make it a very interesting game.
"What we do with it compared to our opponents and how long we can keep it will be the deciding factor."
Before the 1999 epic, Ferguson famously warned his players not to leave themselves in the position of being able to see the most prestigious of trophies without being able to touch it.
The Scot is searching for similar inspiring words of wisdom, although so far they have proved elusive.
"These things usually happen to me about three in the morning when I am trying to get some inspiration from the deep chambers of my tiny little brain," he said. "But at the moment nothing is coming out."
Even at 67 it seems Ferguson is not beyond a sleepless night or two.
The truth is the enormity of what United can achieve in this most historic of cities should inspire all his players.
Title winners three times in succession, the Red Devils are bidding to add back-to-back European Cups.
No side has achieved it since the tournament was rebranded as the Champions League in 1992.
"I cannot explain why it hasn't been done," he said.
"In the history of the European Cup it was done regularly. Some won it two or three times in a row. There were cycles of teams winning it like Ajax, Bayern Munich and Real Madrid.
"Now we have an opportunity to change that and hopefully we can take it."
By changing it, United would get themselves a label any side would want. The label of being great.
It is not a discussion even the most aware of individuals like Rio Ferdinand wants to have, knowing talk can be cheap at this rarefied level of the game.
But if United win tomorrow, they will earn a place in history no-one will be able to erase.
