AC Milan coach Pippo Inzaghi is expecting a passionate derby against Inter Milan.
The match will mark Roberto Mancini's return as Inter coach.
Inzaghi said: "San Siro will be our edge. Mancio is accustomed to many derbies. I am always excited, but seeing the stadium I think we'll realise it cannot be a game like the others. We must seek victory in every possible way, as you win derbies, you don't play them.
"It's a shame for Mazzarri, as it is a defeat for everyone when a Coach is sacked. He will return stronger than ever. We must have great respect for him, as this is a tough profession. Mancini has won a great deal, but I'd never dare think this match would be more difficult with another Coach in charge.
"It will be difficult for anyone to be stronger than this Milan tomorrow night. We must start again from our performance against Sampdoria. The time for talk is over, we'll see on the pitch who is stronger.
"We are ready for this challenge and trained very well. I can't wait for it to be tomorrow. I didn't think about Inter so much as about Milan. I do my team talks from the gut, so I don't know what I'll say to them tomorrow. At times a Coach doesn't even need to talk. Nobody needs extra motivation.
"We've tested out both 4-3-3 or 4-2-4, but I haven't decided yet. There is no ideal tactical system, otherwise everyone would use it. At the end of the day what really counts is spirit, hunger, organisation and sacrifice."
