Normally. Xabi Alonso will definitely come with his own tactics and strategy to manage this team. We all saw how Real Madrid's performance turned out to be last season, and this is why I think Xabi Alonso should do everything possible to get this back to their performance. If it’s using a new method that will make things better for them, he should do that.
Anything that will make us be proud of him being the coach, he should do that. If Real Madrid still perform the way they did last season, it ’won’t be funny, seriously, so it is better Xabi Alonso should make the possible change from now.
It is still too early to get good output from Xabi Alonso. We should give him more time and wait for the season to start. We cannot judge him now and expect the team to improve. However, the goal of a coach is to manage his team well from the beginning and take it to a strong position. He may have tried his best from the beginning to take his team back to its old form. But nature is more difficult than we expect, we just need time to succeed as a team and adapt to the team.
Every coach tries to take his team to the top with his strategy and start making plans for the team to improve. Even identifying and eliminating the weaknesses of his team takes some time. Real Madrid's defense was weak last season, we should see how Xabi Alonso takes action in this regard.
