The Sweden international has intimated that Rossoneri got their tactics badly wrong against the Gunners, while conceding that the players had been guilty of complacency
The Rossoneri took a four-goal advantage with them to north London but ultimately only scraped into the quarter-finals by the narrowest of margins after losing 3-0 on the night at the Emirates.
Allegri has copped a lot of flak for his tactics against the Gunners and Ibrahimovic has confessed that the chosen formation had been a major issue for him.
"I felt out of position for the entire time that we played with three strikers," the Sweden international is quoted as saying by Aftonbladet after the game.
"If you play for a great club like Milan, this [disorganisation] cannot happen. You can lose in many ways but how we lost this time is not acceptable.
"We're Milan and we must be stronger and more solid."
Ibrahimovic admitted, though, that the players had to take some responsibility for a dismal first-half showing in which they shipped three goals, admitting that they had lost their composure and been guilty of complacency.
“We tried to calm each other down at half-time but it was not an easy situation," the forward confessed.
"We had made trivial mistakes. I think that in our heads we had too big of an advantage from the first leg and we were too cautious and did not play our usual game.
"Arsenal had gone into an early lead, doubled it and then found the third goal - all in the first half.
"In the second half then had several chances to score the fourth and fifth goals, but fortunately they failed [to do so].
"It's a relief that we're through to the next round. Every time they attacked you started thinking: 'what if they score a fourth goal?'.
"We won't take anything with us from this game. We just have to learn from our mistakes."
Milan will return to Serie A action on Sunday when they lock horns with Lecce at San Siro.
