The Serbian was left out of the Club World Cup final against TP Mazembe in the United Arab Emirates after playing a significant role in the 3-0 semi-final win over Seongnam Ilhwa.
"I still cannot forgive Benitez. I played great in the semi-finals, scoring a goal, and he left me out of the starting line-up," recalled the 32-year-old.
"With [Jose] Mourinho the same thing happened in the Champions League final, but you cannot compare the two situations. Before [the final in] Madrid I was injured and I had not played in Barcelona due to suspension. I was not in form, but in Abu Dhabi I was.
"Benitez's decision shocked not only me, but the whole team. Fortunately we won."
Despite winning the Club World Cup, Benitez was sacked and replaced with ex-Milan boss Leonardo over the holidays.
"Was Benitez sacked because of me? I don't know," laughed the former Lazio player.
Stankovic has been a fan favourite at San Siro since joining the Nerazzurri in 2004, but he is not certain he will retire with the Beneamata.
"We'll see. I have a contract until 2014 when I will be 36 years old. Perhaps it'll be the right time to retire as an Inter player," he mused.
"Like the national team you must leave room for young players, as they did with me recently. That's life, it's natural."
