While madrid was doing well but could not maintain their position and from in the champions League
Just imagine how a coach deals with several key players getting injured and it is very impossible. Last season Madrid lost many injured players and some players were also often injured which had a bad impact on the team's performance. Like Carvajal who had a long injury while he was one of the best defenders Madrid had. On the one hand, Ancelotti last season only focused on maintaining the attack line without looking for reserve players to anticipate things like this from happening. I am very sure in the coming season you will see Madrid much better than last season.
What I know is that when Ancelotti loses players due to injury, he doesn't trust the young players he has. Just look at how that mistake led Real Madrid to decline. From the beginning Ancelotti was minimal in terms of developing young players, and let's see now Xabi Alonso changing that thinking and proving the role of young people is much better. Last season, Arda Guller was a concrete example where he was rarely used by Ancelotti, but in fact Xabi used Arda more often in the main squad. The result is that Arda has performed impressively so far in the Club World Cup competition.
