I see madrid for now is no longer its lucky season to win the UCL title even though madrid is famously tough in the UCL zone but the gods of luck don't seem to be on madrid's side anymore this season so it is very difficult for xabi alonso to be able to strategize with such a large number of star players..
Real is so cool that not winning the title once causes a storm of emotions and discussions
By the way, the last time I checked the odds, Real was the second main contender for the Champions League title in the upcoming season (after PSG). Therefore, it is assumed that Xabi will be able to cope, and in general, the reasoning about stars in relation to top clubs should be approximately the same. Name me one top club where there are not several stars whose opinions weigh a lot, simply because they give huge impact? There are no such clubs.
Now the odds of Real Madrid to win the champions league 25/26 to 3rd place may be this change after Real Madrid was defeated by PSG --- and PSG is now the first place second Liverpool.
I myself can't judge now and believe Xabi can overcome for the coming season, it could be a tough competitor if they are no longer confused even though there are many star players in it.
