Mourinho confirmed Balotelli's omission after victory over CSKA Moscow last night.
"Will he be called up against Bologna? I don't think so. It depends on him," Mourinho told RAI.
"If he is cold when he scores, why should he be heated with his teammates score? That's just his style.
"Everyone is wrong about something, in that it's not a problem between Mourinho and Balotelli. It is not a personal issue. It is a problem between the club and Balotelli."
