The Swedish international says that the Italian club will always have a special place in his heart and hopes that they return to winning ways after a disastrous campaign so far.
The Swedish international joined Carlo Ancelotti's big-spending project in a deal worth an estimated €20 million over the summer, which looked to have ended his time at Milan once and for all.
However, in an interview with a newspaper in his homeland, Ibrahimovic refused to rule out a return to the club.
"I want the best for Milan, I was very happy there, I felt at home," he told Aftonbladet.
"Milan is a club where I would go, if I could choose today. Usually I do not go back to an old team, but I would like to return to Milan.
"It's a fantastic club. I hope the team does well and returns to success, I can only hope that everything works out for the best.
"If Milan need help then they know where to find me."
