Silvano Martina believes Mancini has treated his client poorly.
"I will only say that with Mancini's arrival on the bench, Vidic didn't see the pitch for two months. He only started when there were no other defenders available, such as against Genoa.
"This is the tactical system he has always preferred and made him into one of the best centre-backs in circulation, so I do not understand why he is not getting more opportunities to play.
"Nemanja never stirs up controversy, but in my view he hasn't been given the best treatment. I cannot explain it.
"He came to Milan with so much enthusiasm, he adapted to Walter Mazzarri's requirements and did his work well.
"When results don't come, you can't just blame one individual, yet everyone seems to assume Vidic is the sole man responsible."
