There's no way he'd come back here. He joined Inter who are first at the moment. I doubt they want to let him go and I doubt he'd like to return after we ditched him. Those rumours had zero sense to begin with.
I personally don't even mind. I wanted him gone, despite some great moves, he always went for quantity over quality. Plus everyone seems to forget how many bad moves he made here. And no, that does not mean I think Paratici is doing better.
Sure, we do need rebuilding, but let's get somebody new here.
