The 37-year-old striker thought his career was over after damaging knee ligaments five months ago, but is getting back to full fitness and could play again before the end of the season.
He said: “I am not setting any deadlines, but I hope to be back for Easter,” he told Sport Mediaset. “I must thank the fans who have kept my enthusiasm on a high.
“I am confident Milan will win the Scudetto. Since the first day Massimiliano Allegri arrived, he tried to talk with the players and seek their opinions. His methods remind me of Carlo Ancelotti’s.”
