You and I know that Real Madrid can not be relegated. Personally, I don't see that happening. As for those praying for that to happen, they are only wasting their time because Madrid is a club beyond relagation. Even if it would take the club president to fire and hire ten managers that will keep them in Spanish top flight, he would do it.
But as at now, it's too early to be saying Madrid would not finish in top four place. Although they lost their last match to Eibar, but that doesn't mean they can't bounce back and have a wonder run of winning streaks, just like they did with four matches in roll when the new coach was hired on interim basis, before they lost their last match.
I don't see Madrid not playing champions league football next season. They have all what it takes to survive their present inconsistent result they are having.
