The Swede's chief representative has dismissed rumours of an imminent return to San Siro for the striker, but conceded the 31-year old could one day take charge of the club
The Swede recently claimed he would be open to a return to the 2011 Scudetto winners, who he left in the summer for the French capital.
However, words of PSG director Leonardo was quick to dismiss his words, and Raiola has echoed the Brazilian's claims.
"Zlatan has [a connection with] Milan but it is difficult to come back. For me it is a closed topic, he is happy in France and will stay there for another three years," the Italian told Sky Sport Italia.
"Maybe in the future, but only as a coach... Is his wife unhappy? She is happy to be in Paris."
Ibrahimovic is currently away on international duty with Sweden, and will face Germany in a World Cup qualifying match on Tuesday.
