The gap between the two Milan sides stands at 5 points after AC lost 0-1 to 7th place Palermo, with Goian netting the winner in a frantic game.
Napoli, Lazio and Udinese sit 6, 7 and 8 points behind the leaders respectively, but Inter who play 3rd from bottom Lecce on Sunday, are the greatest threat for the championship.
A win tomorrow would put them within 2 points of their bitter rivals, with the clubs playing each other next weekend in a game that will have a big say in who wins the title.
