Rodrygo is also in a high place in that list. Even though he doesn't get the number of minutes regularly he is still ready to give his best.

He deserves more chances I think.
Real Madrid are currently in 7th place in the Champions League and maintaining their place in the top 8 looks like an easy task: games against Monaco and Benfica remain. The situation in La Liga is much worse, as Barcelona has a four-point lead, but Real Madrid currently has almost exclusively easy games coming up, so the situation could change. Naturally, if Real Madrid keeps dropping points, Xabi will be in trouble.
For now I don't think Xabi Alonso should be under danger. It isn't fair for him. If they defeat Alaves tonight the point difference with Barcelona will stay as 4 in the La liga. Never a gap that can't be closed.
Real Madrid can still finish the CL league phase in top 8 too as you also said. Even if they don't there is no problem. They are still going to be in playoffs. The last champion here didn't do a great work in this phase for example.
