Max Allegri admits that Milan go into the derby with just a point from two games, but claims the beauty of football is that everything can change.
Milan have a two-point lead at the top of Serie A and can be overtaken if they suffer defeat to Inter at San Siro on Saturday evening.
"We've taken a point from our last two games, but football is beautiful because everything can change," Allegri said.
"We have been top for 21 weeks. We knew that you couldn't win the Scudetto with a month to spare. We need to think about getting a result tomorrow.
"It's an extremely important game, but more for them than for us. Milan will be ahead at the kick off. If we win, we go five points clear with seven games left. It wouldn't be bad, but it's true that in two games we have taken only one point.
"I don't like it when people talk about us already winning the Scudetto. You win the Scudetto if, at the end of the season, you have a one-point advantage.
"We are going forward game-by-game," he concluded.
