I don't believe he'll be fired immediately. Xabi is a very successful coach, and if his Real Madrid career progresses normally, it could last a few years. Spain is a place he knows well, and he's a coach who's attuned to young players. I still remember what he did at Leverkusen. They didn't lose a single Bundesliga loss for an entire season and reached the UEL final. I have full confidence they'll do the same with Real.
Currently, Xabi is doing his best, so there is no reason for him to be fired in the end because, after all, progress and the process are still underway to build a healthier Madrid squad than before.
Trophies are always the goal, but when they have tried their best even though they did not get the maximum results, I think Madrid will not do anything unless Madrid's performance is far from expectations. However, for now, we know that their current condition is still very good, so it's still too early to discuss such matters because the situation is still under control.
What Madrid needs to continue doing now is to maintain the same level of performance and keep it up until the end, while conducting evaluations when they notice gaps that cause Madrid to lose focus slightly. As long as Xabi succeeds in doing that, his future is clearly secured.
