AC Milan icon Billy Costacurta believes the derby with Inter will decide the title.
Costacurta feels Inter will go into the game not in the greatest shape.
He explained: "The five points ahead of AC Milan are not few. The derby will be very important.
"Inter had a tough game with Brescia, which they are now recovering from. Then there is Bayern Munich. I believe that everything can change up to the derby."
Leonardo, in his view, has a different approach compared to other Italian technicians.
"Leo has a different approach, made of smiles and words, but when it comes to talking about the game, he can be heard."
