The tight match schedule has increased the vulnerability of player injuries, and clubs that participate in many competitions in one season will be faced with great concerns. Players do not have enough time to rest, we have seen the journey of big teams in the Champions League, especially in the League Phase, they have difficulty performing consistently. In addition, international matches also make players very tired. Let's see how the Champions League next season will go, PSG may not be able to defend the trophy, and the main spotlight may be on Madrid again. Many are curious about Xabi Alonso's performance. we know being a Madrid manager is not easy, he must be able to present a trophy or end up being fired.
The first season of the Champions League with a different format has made quite a few clubs and players feel burdened because they are forced to keep playing even though the break is very short and currently the format will still be the same which must be taken as a notice for clubs in the Champions League so that they can spot mistakes in the first season because in any case the tight schedule will still be unavoidable for next season.
If in the end the same mistakes in the previous season are not minimized with the right player rotation, then it is possible that there will be a storm of injuries for several clubs like what happened to Madrid last season, especially for now as you said that Madrid will still be one of the attractions where next season is proof of Xabi whether he is capable or not in managing the Madrid squad well.
So apart from adaptation, chemistry and mentality that must be improved, he must also play a good enough role to support Madrid's performance to be better than last season.
