"This was a very disappointing and unacceptable performance, which confirms the urgent need of a change," Berlusconi told reporters after the defeat to Sassuolo.
Allegri, meanwhile, was in a defiant frame of mind when he emerged to face the media but admitted that he could well be relieved of his duties.
"I'm ok with myself," the Livorno native hold Rai. "I have always done my best and I'll keep on doing that if I keep my job.
"Anyway, whatever happens, I'll accept it."
Milan's loss leaves them 11th in the Serie A standings, a staggering 20 points behind third-placed Napoli.
