The young striker is keen on leaving the club on loan.
“Nothing has changed since the last time I called up a squad,” Mourinho told a news conference on Monday.
“His way of working is the same, his joy, or lack of joy, is the same, his attitude is the same.
“The only thing that has changed is that his brother has made it clear that Mario is thinking about being loaned out.
“We’ll wait until the closure of the transfer market at the end of January, when he realises he’s staying here. At that point there’ll be no alternative to concentrating on his work with Inter.
“Maybe then his attitude will change, maybe he will return to the squad, but at the moment he does not seem to be in the condition to play.”
