Bayern Munich's first season under Tuchel was tough. He had local and European goals. Tuchel's management expected a treble, which may have been unrealistic.
However, Dortmund's final-match disaster helped Tuchel defend the Bundesliga title. The club cannot continue to rely on such luck. Bayern must bolster their roster in the summer transfer window to win. Failure to do so could cost them the Bundesliga championship and the Champions League.
For the next season's competition, even though Bayern Munich are still favored to win the Bundesliga title, it will be a problem if they fail to maintain their consistency during this period. Moreover, a busy schedule for other competitions such as the UCL will greatly drain the stamina of the players. Therefore, Bayern Munich needs 22 players of equal quality, be they starters or reserves. But until now the problem regarding who will be their main striker is still unresolved and I'm quite surprised why Bayern Munich are still so insistent on getting Harry Kane, even though they can get another striker who has good goal productivity.
