Inter Milan chief Piero Ausilio admits tension between ultras and Mauro Icardi influenced defeat to Cagliari.
Fans are calling for Icardi to be sacked as captain after comments made in his new book.
"These are things which you do not want to see, tomorrow we will have a meeting.
"This situation has divided the stadium, which did not support 100% Icardi nor the team," lamented Ausilio.
Icardi also missed a penalty on the day.
