New players and coaches are still making arrangements on how they can have a successful season. Just as you said about Xabi Alonso, he is still making arrangements for his club, as he is trying everything possible to have a successful season at Real Madrid in his first season with the team as a manager. I know he will face many challenges because he needs time to get the players adapted to his style of game.
Xabi Alonso is a talented coach. But we don't know if he will succeed with Real Madrid. A mediocre team like Leverkusen dominated the Bundesliga with Alonso. But Alonso has never been the manager of a big team like Madrid before. It is also quite difficult to control so many star players.
Alonso will definitely try his best to succeed in his first season with Madrid. Madrid management is ready to take all the necessary measures to strengthen their squad even more. Madrid is also willing to spend a lot of money. Alonso will definitely have to bring good results. He should consider the defeat against PSG as an accident and move forward.
