The Rossoneri have been vocal in their desire to bring former boss Ancelotti back to San Siro following his sacking by Real Madrid.
And Berlusconi claims he has the backing of the supporters as he attempts to appoint the three-time Champions League winner in Filippo Inzaghi's place.
"I hope Carletto comes back to us, we are willing to invest in him. I hope there is a good chance he'll be the next coach of Milan," he told Sport Mediaset.
"Galliani and I are not the only ones who want him to come back. All Milan fans I've spoken to want him back."
Ancelotti himself says he intends to take a year out of the game in order to have surgery on a small issue in his back.
Berlusconi, however, hopes the operation will not scupper his plans and admits he is not currently contemplating any other candidate.
"He needs a small operation and he'll make a decision afterwards, which also takes into account his family," he said.
"I don't want to think of another possibility if it isn't Ancelotti. If he doesn't come then we'll look at other options."
Berlusconi also admitted he is determined to bring Ibrahimovic back to the club from French champions Paris Saint-Germain.
"I'm fixated on his return, although it's a very difficult thing to make happen, and it will take patience," he added.
"But he's magnificent on the pitch."
