Having signed for LA Galaxy in 2018, he will bring his two-year stay Stateside to an end in December after scoring more than 50 goals.
The veteran Swedish striker had not given any specific details of his impending move back to Europe, but any plans of a surprise announcement may have been spoiled by MLS commissioner Don Garber.
Speaking to ESPN, Garber referenced the impact that Ibrahimovic has had on MLS as a whole – and seemed to reveal his next move.
“Zlatan is an interesting character. He’s a thrill a minute. You need to have those guys that are breaking through like David Beckham did,” Garber said.
“A 38-year-old guy, who is now being recruited by AC Milan, one of the top clubs in the world.
“He’s almost set records with how many goals he’s scored over the last two years. He’s exciting on and off the field, he certainly keeps our hands full!
“At the end of the day I’d love to see him back but that’s going to be up to LA Galaxy.”
Ibrahimovic played for AC Milan between 2010 and 2012, between a short stint at Barcelona and a long, successful stay at Paris Saint-Germain.
He then moved to Manchester United in 2016 and had been linked with a move back to Old Trafford, but it now appears a return to the San Siro will instead be his immediate future.
Milan are struggling in Serie A this season, sitting in 12th place with games against Juventus and Napoli coming up next.
They have already sacked manager Marco Giampaolo after just three months in charge, replacing him with Stefano Pioli at the start of October.
