I honestly don't really understand how the coach should prove himself in the first few games, he basically just came in and did minimal work. Now, during the Club World Cup, Real are playing well, but I don't think this tournament can be taken seriously enough to draw conclusions about Alonso's performance, so the only place to evaluate him is La Liga and Champions League.
Agree. FIFA Club World Cup is not being taken seriously by any team. So we don't know yet whether Xabi Alonso will be successful with Madrid. Xabi is experimenting with Real Madrid's squad. And Madrid's performance seems to be somewhat stable. But it's not yet time to reach a conclusion.
Real Madrid won 1-0 with Juventus. In this match we saw Tchouameni in defense and Alexander Arnold in midfield. I don't think Madrid will play in this formation next season. Alexander Arnold is mainly a defender and Tchouameni is a defensive midfielder. Also, if Mbappe is added to the starting XI, we will see more changes in the match tactics and formation.
