The Sun says Young stormed out of training in order to force through a move to Inter.
Young has agreed to join the Serie A side in a £1.5million move and is expected to undergo a medical on Friday.
Young walked off the training pitch last Friday and went to work in the gym on his own.
That resulted in Young being left out of the squad for the win against Norwich.
The United captain's current deal expires in the summer but he was determined to leave in this transfer window.
United were eager to retain Young's services but he rejected their offer of a new one-year deal.
