But it doesn't matter that hes the best manager ever. A title like that is a result of an entire career. In the moment, hes not able to turn this ship around. As counterintuitive as it sounds, a worse manager would be more beneficial for this team.
I am also firmly in the Ancelotti fuera camp for Madrid, which is still a minority among us, precisely because of his trophy cabinet. But that doesn't matter, when you're not able to implement your ideas on the pitch, or if you don't have any, best thing you can do is leave it to someone else.
Half a season of bad results is more than enough time for big clubs like City and Madrid. Just leave and the shroud will be lifted. You either die a hero or live long enough to become the villain.
