McGregor, 41 years old, is currently facing assault charges. However, McGregor insists that he doesn't want McGregor to go to jail.
Facchinetti said that he would decline a large settlement in order to drop the case.
According to The Mirror, the musician spoke to Italian radio and said that he could have remained silent and not spoken to anyone. But, he said, "I could have shut down and not said anything, but I'm here because it is important to me to tell it."
"If McGregor's lawyer called me tomorrow to offer me EUR10m [PS8m] for the withdrawal of the complaint and everything, I would not say no."
Police were called to investigate a scuffle between the UFC legend and the two men while they were attending an event at St Regis Hotel in Rome.
McGregor, 33, along with his partner Dee Devlin, were in Italy for a few short days to witness the christening in the Vatican of their youngest child Rian.
However, the trip is set to end on a low note with Facchinetti (39) and Wilma Faissol (39) making allegations to their 1.5 million combined Instagram followers.
Facchinetti uploaded a video reliving the incident, and showed off his lip cuts.
Wilma also posted a series Instagram stories in which she accused the fighter of attacking her husband. She claimed that Notorious could have killed her.
The cause of the alleged melee is still unknown. Facchinetti claims that McGregor was enjoying a drink with the men before he 'changed' his mind and punched Facchinetti in the face.
SunSport reached out to McGregor's team in an effort to get their opinion on the incident.
According to Italian Police, they arrived on the scene at 5.30am following the incident.
Michael Bisping, a fellow UFC legend, has slammed the Notorious despite him being innocent until proven guilty.
McGregor, 42 years old, told McGregor that he should pick on someone of his size or larger and called McGregor "a bully".
