Ibrahimovic was Milan's joint top goalscorer, netting 14 times, when the Rossoneri lifted their 18th and last Scudetto in 2011.
The 39-year-old has been in near unstoppable form this campaign, scoring 10 goals in six league matches to fire Stefano Pioli's undefeated Milan to a three-point lead over city rivals Inter atop the table after 11 rounds.
Defending champions Juventus have dominated Serie A over the past decade but Ibrahimovic is full of belief that Milan can prevent the Old Lady from clinching a 10th successive title.
"The team must have the courage to dream of winning the Scudetto, we have a long way ahead," said Ibrahimovic, who is back training ahead of Wednesday's trip to Genoa following a hamstring injury.
