Gravina is demanding Juve leave the Super League association or face expulsion.
He declared, "If Juve is not removed from the Super League, they will be out of Serie A. Another nine teams returned, there are three others that are resisting. Among them, as you know, is Juventus. If at the time of registering for the new season of Serie A they have not withdrawn from the Super League, Juve would be excluded.
"There is a very clear rule of the International Olympic Committee and in our statutes.
"If the club does not accept it, I am sorry, but it will be out."
