In addition to defense, their attack line also needs improvement due to the lack of goals from the center forwards. We can see that the Bayern Munchen winger is more dominant in scoring goals, their last four matches have proven that. At present, Tottenham have rejected an offer for Harry Kane. Automatically Thomas Tuchel must look for a striker for next season, otherwise Bayern will have difficulty in the Champions League.
If Bayern Munich doesn't manage to get a new striker for next season, Bayern Munich will not only have difficulties in the Champions League, but Bayern Munich may also have difficulties in the Bundesliga because other teams like Dortmund can also be strong next season even though for now Dortmund looks like not taken into account by many people. So Thomas Tuchel's own task for now is still very much because apart from having to be able to find better front-line players, Thomas Tuchel must also be able to make Bayern Munich stronger next season with the existing players.
I think in the Bundesliga, Munchen can easily dominate the table, at least under a little pressure from Borussia Dortmund. But in the UCL I don't think they can talk much about the current composition of players.
Actually, if the composition of the players is not very good, in terms of any competition a team will find it difficult to dominate in the standings, especially if there is pressure coming from the opponent. And when the opposing side already knows about the weaknesses of a team on which line, of course it will be very troublesome for Bayern Munich to rise in the Bundesliga and also the UCL.
