Real Madrid could only win by a narrow 1 goal from Juventus and overall Real Madrid's performance in the club world cup competition so far has not been that impressive although this cannot be used as a reference because Xabi Alonso has also just become Real Madrid's coach and he still needs time to adapt.
However, from what Xabi Alonso achieved with Leverkusen, even the phenomenal season in the Bundesliga when they were undefeated cannot be compared to Xabi Alonso at Real Madrid now, this is clearly very different, especially the pressure of being Real Madrid's coach.
Madrid is a team with a lot of history, as well as the star players it has. A big challenge for Xabi is to be able to make the team play amazingly. Of course, it will take time in the process. The playing style of Madrid players will still be greatly influenced by what Ancelotti previously implemented. It was even acknowledged by several Madrid players in Xabi's first match as a coach.
All will require adjustments and adaptation processes, both players and coaches, in implementing training and tactics.
