The Rossoneri have refused to rule out a move for the experienced attacker as they have nothing but fond memories of his time at the club.
AC Milan president Silvio Berlusconi has insisted that Paris Saint-Germain star Zlatan Ibrahimovic will always be welcome at the San Siro.
The 33-year-old enjoyed a hugely successful spell with the Serie A outfit between 2010 and 2012, before leaving the club for PSG.
Ibrahimovic has been heavily linked with a return to Milan this summer, though, and Berlusconi has made it clear the team will always have room for the Sweden international if he wants a comeback.
