Xabi Alonso is new to Real Madrid, and I think he still needs time to adapt. So, the Club World Cup's outcome shouldn't be used as a pretext to assume he's failed.
There's still plenty of time for Xabi Alonso to improve the team, especially their defense, which still looks very weak.
And Real Madrid must still be considered for next season's Champions League campaign, as they possess a very strong mentality and can perform better in high-tension matches or under pressure.
I don't think anyone will blame Xabi Alonso for Real Madrid not reaching the final in the club world cup. Let's not forget that Real Madrid had not been in great form before Alonso took over the team. It's been just a few weeks since he arrived at Real Madrid, and he hasn't had enough time with the squad even before this Club World Cup tournament started. So, he may not have had enough time to choose the players that suit his tactics. He's simply trying to use the squad that the former coach was using.
Therefore, there is nothing to blame Alonso for, and we can't use this Club World Cup tournament to predict how he will perform next season. Even if we want to judge him based on this tournament, reaching the semi-final is not a bad result for a new coach.With the improvements I’ve seen in Real Madrid recently, I believe Xabi Alonso will do great at the club and achieve a lot. But let's wait and see how next season performances will be both in the Champions League and in their domestic league.
