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.
It remains to be seen if they will change the tactics of the game at all, it's obvious that Alonso will try to find a balance between defence and attack, but that may not work and will have to go back to dominating the attacking line. I think everything will become clear from the first games. And the attitude of the team and the coach and it will be seen what work they have managed to do
