Although the victory saw them move five points clear of Inter and six ahead of Napoli, Pato is not getting overly excited.
"We're not thinking about the Scudetto," said the Brazilian who won a penalty, set up the second and slotted home the third. "We're focused on our next game against Juventus."
The two giants meet on Saturday night in Turin in a tie that Milan will start as favourites, especially given Juve's woeful form.
"I like playing in this team," Pato continued. "There are great champions here, but they are not teammates, they are my brothers.
"I'm happy that we played a great game.
"I always want to play, but the Coach makes the decisions which he thinks are best for the team and I know I have to work hard."
