The slumbering Italian giants are keen for the Special One to return to the San Siro and repeat his heroic spell with local rivals Inter.
Mourinho, expected to leave Real Madrid this summer, could be tempted - especially as the odds are mounting against him making an emotional return to English football at the end of the season.
The attraction of Milan, one of the world's most successful clubs, would be hard for him to ignore.
Milan president Silvio Berlusconi has pledged to restore the club to its former glory.
He admits he failed with a bid to bring in ex-Barca boss Pep Guardiola.
So now Mourinho has become Milan's top target - if they match his £13.5million Real salary.
