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.
And because Ancelotti has left Real Madrid until the Real Madrid coaching position is held by Alonso starting next season, of course it will also raise greater curiosity about how Alonso will coach Real Madrid by making changes that can revive Real Madrid's performance. Because it is indeed very inappropriate to blame one party in terms of team performance, be it the coach or the players because when a team becomes weak, then the responsibility and guilt must cover all aspects of the team.
