You are right. Alonso is new to the Madrid squad. and he has never managed such a big club before. So some time is needed. We cannot test Alonso's ability through the match against PSG in the fifa Club World Cup.
If Madrid had organized a few friendlies before the start of the season , it would have been a little easier for Alonso to stabilize Madrid's performance before the start of the season. But Madrid is not playing any pre-season matches. If Madrid's performance is unstable at the beginning of the season, then Madrid will fall behind in the title race. Alonso must be aware. Even if Madrid's performance cannot be completely stabilized, they must try to earn full points in every match. Madrid will play against osasuna in the first match of the season. The opponent is not weak at all. Even then, Madrid must start the journey with a win.
Alonso is very keen to see how his players prepare and plan for the upcoming season. He may be prioritising training over playing pre-season matches, as he is still new to the team and must familiarise his players with his new tactics. The start of the season may not be very good for Madrid or should not be expected to be good. Because for Xabi Alonso, it will be the first match of the new season with Real Madrid. If Alonso can win the first few matches brilliantly, then the fans will definitely be pleased with him.
But the question is, will the players be able to adapt to Alonso's tactics at the beginning? Or will Alonso's tactics be effective in a new team, especially where Real Madrid is a big club? I want to leave the match against PSG in the FIFA World Cup out of the discussion.
