I wouldn't put the blame on Ancelotti or the players, because the team lacked the quality of a good defense and midfield due to injury on their players which started in the beginning of the season. Ancelotti has done his best for the club and he has to leave, let someone else take over. If a coach continues winning trophies, no club would replace him.
Nobody expected so many defenders to be injured, and Ancelotti certainly doesn't want to be in that situation. But strangely, when it happened, and he had the chance to fix things (when the January transfer window opens), he did not take advantage of the opportunity, and it was as if he underestimated the problems they were facing. So for that reason, Ancelotti is indeed to blame for their failure.
I think that's the reason why he stepped down, because he felt he had made a mistake that made Madrid fail to win a trophy.
Sometimes I don’t know why people blame the managers when a team fails, although the managers are the ones who manage the players, but sometimes the managers cannot just act on things like that without getting direction from the management. Real Madrid is a strong team, and everyone knows that, but things did not work out for them this season; they can't be good all the time, and we all blame Ancelotti.
During the transfer window in January, I expected Ancelotti to fix the problem, and he did not do that, but I didn’t say he underestimated the problem. Maybe the management are not used to that, and they think the available players can make things work for them,
although if you observe, you will notice that Real Madrid are not used to that method of getting in a new player in every transfer window. This is because they believed in their player, but unfortunately things did not work out. so completely I won’t. Ancelotti is the only reason why Real Madrid fails this season.
