That is because many of Real Madrid's defenders are injured but I never doubt Real Madrid's management because they have proven that when going through a bad season, Real Madrid's management will make major improvements and that is possible to happen next season.
Now Real Madrid has officially recruited Xabi Alonso as their new coach, that is the first step in a major evaluation and most likely there will be many things that Xabi Alonso will fix, especially since Real Madrid's management never skimps on bringing in new players.
Of course he will evaluate, he knows what he wants to build on transfer window for next season. Every coach must think about that all the time. But, this is Madrid where the players several of them have star characters. this is very different if we are compared his team at Leverkusen. The ego of star players tends to be bigger than players who don't have any status at all. This is the real challenge for Xabi. Mbappe often show his ego, can Xabi make Mbappe follow his strategy? This should be the reason why Xabi needs to know the character of each player with adaptation and evaluation first. Likewise, players also need to adapt to Xabi's style. It's no longer about money when coaching Madrid, but the ability to unite a team.
