Well they probably aren't willing to give up on their huge and unfair sallaries, to which they are due regardless they play or not.
They just won't do it, there's no club in the world which will play half of what they earn in Juventus. If we want to rescind without their consent, we would have to pay a shitload of cash anyway. It's not happening. The best thing that could happen is to loan them out on a free and at least find a club who will play half their wages.
