#2 Have a good backup squad in place
In recent times, injuries before crucial matches have been a major problem for the Bavarians. For instance, during the 2017-18 Champions League semi-final against Real Madrid, Bayern Munich were missing key players like Arturo Vidal, Arjen Robben, David Alaba, Manuel Neuer, Jerome Boateng, all of whom were otherwise regularly a part of the playing XI.
A similar problem occurred to them in the 2016-17 Champions League campaign. Since Bayern did not have a good backup squad, either their players were inexperienced or too old, they failed to win these important games.
The Bavarians must strengthen their bench strength and bring it to the same level as that of Juventus or Real Madrid if they are to have any solid chance of winning the Champions League soon.
