Carlo Ancelotti has insisted that he could never betray Milan by one day taking charge of city rivals Inter.
The Chelsea boss has been talked about as a possible Nerazzurri Coach of the future, but he claims he wouldn't be able to do what Leonardo has done recently.
"If Inter President Massimo Moratti did call me in the future then I would, politely, decline the offer," he told Italian newspaper Il Giorno.
"I'm a Milan man. I spent 13 years at Milan and for me it is impossible to forget the past. I wouldn't go to Inter, but I do respect the choices of others."
Ancelotti represented the Rossoneri as a player and Coach, winning the Scudetto and the Champions League in both roles with the San Siro giants.
Leonardo also represented Milan as a player before spending last season on the Rossoneri bench.
He quit in the summer, but returned to the Serie A scene in December when Inter showed Rafa Benitez the door.
Ancelotti could be back in Italian top-flight football next season though as he may be targeted by Roma if his Stamford Bridge stint comes to an end.
