AC Milan coach Leonardo is expecting an "extraordinary" derby tonight against Inter.
Milan are on a great run and go into the game favourites.
"Tomorrow night's game will be extraordinary, you just need to see the expectation around a match like this," said Leonardo.
"It'll be watched live all over the world, including in Brazil, where they are big Milan fans."
He added: "I don't think it will be decisive, as there is a long way to the end of the season and we can't make realistic calculations until we play that game with Fiorentina.
"It's still very important for a thousand different reasons. It is the kind of game that leaves a mark, both good and bad.
"I cannot think of what the result might be tomorrow. I have never started a match with anything less than victory in mind."
