Berlusconi also distanced himself from recent comments suggesting that he does not have a particularly good relationship with Allegri.
Speaking at a press conference ahead of Sunday night's derby against Inter Milan, Berlusconi insisted that there are "good relations" between the two men, claiming that he always accepts the Milan manager's advice.
"The good relations between me and Allegri are constant – there is cordiality and mutual respect," Berlusconi told reporters.
"On many things we agree. I have always accepted his advice and he has always accepted my explanation.
"After a difficult start we have recovered form and balance. There is harmony in the dressing room where no bad eggs can create a negative energy."
AC Milan are in third place in Serie A after a recent run of fine form.
