Adolfo Gaich struck the winner in Turin.
"We knew what our path was. I told the guys we could earn points in Turin," Inzaghi told Sky Italia.
"We received a lot of criticism of late, but we made a record in Serie B, and I'd like people to see how complicated that league is," Inzaghi continued.
"These are extraordinary guys. Before the game, I told them that I would thank them for life. I had already prepared the speech for defeat, I am superstitious, and I have to be rational," he added.
"It won't happen many times to gain earn four points against Juventus," the coach continued.
"I don't look at the last two-three games. We were not ourselves. We lost to Inter, but it can happen. The environment had lost a sense of reality lately.
"At the beginning of the season, we would have been happy to be where we are now."
