The Swede has been a big hit since his January arrival from LA Galaxy. But his initial deal only runs to June.
And given owners Elliott Management's newly imposed salary cap, Italian expert Gianluca Di Marzio says the Swede is likely to walk.
He says it is not yet known whether he will stay or not.
"I have no big signs that Ibra will play another season with AC Milan, beyond the (€2.5m-a-year) salary cap," Di Marzio said.
