"We will win the game on Sunday," he said. "Our performance level will win the game for us.
"But with the ability in this team, I know the results we have been having will not carry on for long."
Given the performance level United have reached so far this term, Ferguson can barely believe the meagre points tally they have amassed.
Although last weekend's Manchester derby ended in defeat, in every aspect of the game - other than the goals column - the Red Devils were totally dominant.
"City did not even get a corner," Ferguson reflected.
"Has there ever been a derby game in history where the home side did not win one corner?
"I am perfectly aware winning is the name of the game, and we do not like losing. But everyone played with great intensity and commitment, and their passing was excellent. It was just the finishing that let us down.
"You just have to ride along with it. There is no point me deserting players who have proved their ability at the top level of the game.
"So, what is the issue? The issue is that - because we are not winning games - there is a different slant on everything. I understand that."
