The Swede's contract with Major League Soccer side LA Galaxy comes to an end at the end of this year, and he has once again been linked with a switch to Europe.
Bologna director Walter Sabatini claimed the 38-year-old wants to join them, while MLS Commisioner Don Garber recently claimed that the striker is a target for AC Milan.
"Zlatan is such an interesting guy," Garber told ESPN.
"He keeps my hands full and my inbox full, but he's a thrill a minute.
"He is a 38-year-old guy who is being recruited by AC Milan, one of the top clubs in the world."
However, Milan manager Stefano Pioli insists it's too early to be talking about a possible move for Ibrahimovic.
"Ibrahimovic? Surely he is a great player and great professional but it is too early to talk about the market.
The 38-year-old bagged an impressive 31 goals and eight assists in 31 appearances for LA Galax this past season.
