MONZA are set to be handed an X-rated reward after they shocked Juventus in a 2-0 win on Sunday.
First-half goals from Patrick Ciurria and Dany Mota saw Monza claim a massive win over Massimiliano Allegri's Italian giants.
It meant Monza went above Juventus, who were recently handed a 15-point penalty for a transfer scam, but also means Berlusconi must honour promise to his suprise stars.
At the club's Christmas party last month, the former Italian Prime Minister promised his players a "bus full of prostitutes" if they could beat AC Milan or Juventus.
And following the shock result on Sunday, he has now revealed he has been asked to keep the promise.
Berlusconi, 86, told La Repubblica: "I already received 100 calls asking me to stand by my word."

The club's social media account also got involved with the joke, posting a photo of the team bus without a caption.
At the time, the controversial Italian declared he wanted to find a new way of motivating his players.
During his Christmas speech, he said: "We found a new coach, who was at our youth team, he is good, smart, kind, and able to stimulate [motivate] our lads.
"I decided to add an extra stimulation.

"So I told the lads you will play Milan, Juventus, etc, so if you beat one of these big teams, I will have you greeted in the locker room by a bus full of wh***s."
Since then, Monza have boosted survival hopes with two wins and three draws since the World Cup - including results against Inter and Sassuolo, who just thrashed AC Milan 5-2.
Monza achieved promotion to Serie A last season after winning the Serie B play-offs.
They were brought by Berlusconi in 2018.
The Italian has previous experience running a football club, having owned AC Milan between 1986 and 2017.
