The Rossoneri have already stated that they will contest the suspension but the Sweden international believes that he needs to start learning from his mistakes
The Sweden international was sent off 19 minutes into the second half of the game at San Siro for slapping Salvatore Aronica in the face as he was dragging team-mate Antonio Nocerino away from the Partenopei centre-half.
Ibrahimovic has been hit with a three-match ban for his rush of blood to the head but Milan now intend to fight the suspension.
However, the 30-year-old forward has no complaints about his dismissal.
"I did a stupid thing,” Ibrahimovic admitted during an interview with ‘Striscia la Notizia’ on Canale 5 on Monday night.
“It happens, it happens. [But] I have to learn from my mistakes. I don’t need the television cameras to know what I’ve done. I made a mistake.”
Should Milan fail to overturn Ibrahimovic’s suspension, or at least have it reduced, the player will miss the Rossoneri’s upcoming Serie A clashes with Udinese and Juventus, as well as their trip to Cesena in between.
However, Ibrahimovic believes that Massimiliano Allegri’s men have sufficient quality to cope in his absence.
“I have confidence in the team,” he stated. “They will do well without me.”
Ibrahimovic is, however, eligible to play for Milan in Wednesday's Coppa Italia semi-final clash with his former club Juve.
