Players come and go with the philosophy of the coach who makes them play, unfortunately the coach of Raela Madrid has a team designed and built on the structure wanted by Ancelotti, and this causes difficulties that can lead to tactical errors, he needs time to understand what to change and how to fix it
This is common in football, with players coming and going based on need, especially after seeing their previous performances. This isn't entirely the case, as I've seen several players adapt quickly to Xabi Alonso's strategy. I think it's just a matter of time, as we haven't yet fully seen Xabi Alonso's performance at Real Madrid, and given his abilities, it probably won't be much more difficult.
Some weaknesses may still exist in certain positions like a creative midfielder, as they are crucial for a player capable of controlling the rhythm of the game. Currently, Real Madrid doesn't have a player with this ability, but I'm confident Xabi Alonso can create new players in those positions.
Yes, we have not seen the full strategy of Xabi Alonso for Real Madrid at the moment because he has not been able to fully invest the team so far. Xabi Alonso is a great coach who has adapted to Real Madrid a lot in a short time but if he spends more time with the team he will definitely be able to bring the team to a better position. Since at the moment he is ready to take a good step for his team quickly and he will decide where the creative players are needed. It may take some time for Real Madrid to fill the places where they are still weak but we hope that this will be resolved very soon. Since Real Madrid does not have a very good midfielder at the moment due to which they are feeling some weakness but of course we can hope that Xabi Alonso will strengthen those weak positions soon.
