I believe that Madrid already know that the first season for Xabi Alonso wouldn't be a superb one. Their corncern is to get a young good coach that can spend time with the team improving their performance overtime. I know that in the next two or three seasons, Real Madrid will be very solid and deadly. If the team is strengthen, no club will be able to win them easily.
If team have good depth it's never been problem for them to have good results from start as Arne Slot done at Liverpool Xabi Alonso can do here at Real Madrid because they are having many top quality players, and they needed to be adjusted with his strategy.
They have start in FIFA Club World Cup which was not bad for them now things could be on another level in La Liga and UEFA Champions League which will not new for Xabi Alonso he can manage things as he wants his strategy works at Bayer Leverkusen where he won good matches and trophy as well. Real Madrid problem was defense which hurt them now he is working on this Barcelona is also doing their work this could be amazing season ahead of us with both will do their best and keep things at their best for title.
