Ancelotti has never been a manager to let sponsors decide his lineup.
Closest it came was at Real Madrid when Bale *had* to play despite having just signed and not trained whole summer. He played him and Bale promptly got injured.
But Ancelotti is well used to managing big egos.
I have seen a video of Casemiro doing a ridiculous two footed tackle from behind on Endrick, which could have easily snapped his leg in two like a twig if his foot was not off the ground. That's the kind of tackle you get red carded for plus suspension. And he did it *in training*, against a teammate. Not something I ever thought I would see Casemiro do, and I've watched him play a lot while he was at Man Utd.
Anyway, while no one else is scoring Ancelotti simply can't afford to keep ignoring Endrick.
