The Rossoneri convincingly defeated Chievo 5-1 at the weekend.
"The month of November is very important. There are six fundamental games between the League and Champions League that will allow us to move up the tables," Galliani said.
"We are still far behind, we are 10th in the League, we must rise. It will not be easy, but we have to try.
"Tuesday's game with Malaga is a major challenge because if we win we would take a major step forward towards qualification.
"In the League we have collected seven points from our first eight games and as many in the last three Our performance needs to improve, it will take time and we are still very far away."
