Borussia Dortmund may have been very unlucky this season but overall this team has remained consistent as a team that has always been at the top of the Bundesliga even though they didn't win.
This season, Borussia Dortmund has not always been at the top of the standings, although in the end Borussia Dortmund began to often be seen at the top of the standings, but if you look at it as a whole in one season, Borussia Dortmund has almost often swapped its position with Bayern Munich in the Bundesliga standings so that only they are almost often seen in the top positions.
Thomas Tuchel will build the Bayern Munich team for a better season of course and we will see Thomas Tuchel's real performance, this season Thomas Tuchel has been considered a failure to handle Bayern even though this team won the Bundesliga but overall after Thomas Tuchel handled this team it did not develop quite the opposite, maybe It's because of time, but if Thomas Tuchel starts this season and builds the team he wants then there's no excuse for him if Bayern can't get back to their best.
I would not consider Thomas Tuchel to be a coach who failed at Bayern Munich at the moment, because apart from the problem of a very short time for Thomas Tuchel in terms of handling Bayern Munich this season, Thomas Tuchel also still needs some new strategies to be brought into the team that at the moment basically it is very possible next season so that the assessment of Thomas Tuchel's failure or success at Bayern Munich is when next season is finished, not this season.
