Thomas Tuchel is an experienced coach who always has a way of dealing with any problems at his club even though goalkeeper Manuel Neuer has to rest until next season but I'm sure that the coach will get a replacement soon.
Not only that, but Thomas Tuchel is also thinking about a player in a line other than goalkeeper, because the Bundesliga will start soon at the end of next week so Thomas Tuchel will have to make more use of this short time to find every replacement he has been looking for.
About Borussia dortmund I am also very sure that this is his chance to compete and replace Munich because of the loss of his best goalkeeper so that dortmund cannot miss this situation to get the Bundesliga title this season which will start later.
The rest of the best goalkeeper from Bayern Munich is indeed a pretty good opportunity for Borussia dortmund, but it's also not solely that Bayern Munich will be weak in the Bundesliga because if Bayern Munich's players are still good enough next season, of course Borussia dortmund too it's not easier to beat Bayern Munich.
