Philippe Mexes is preparing himself to be jeered by the Roma fans when Milan arrive at the Stadio Olimpico on Saturday.
The Frenchman joined the Rossoneri on a Bosman in the summer and he will face his former club for the first time tomorrow night.
"I was whistled even when I wore their colours, but I'm not bitter," he told the Gazzetta dello Sport on Friday.
"That's just one of the passionate ways to live football.
"Let's say that I expect to be jeered, but I do hope that they are then transformed into applause."
The Frenchman, 29, joined the Giallorossi in 2004 after seven years in his homeland with Auxerre.
"I don't consider my Roma exit as a divorce," he added. "I spent seven wonderful years there. At a certain point the club's management changed and my renewal was no longer a topic for discussion."
Mexes is now back in action after recovering from a knee ligament problem that kept him out for six months.
"I still need a bit more training to return to my best," he added. "I think that I'll be ready for 90 minutes in about two or three weeks."
