Bayern Munich is playing really great football. They have some great players in their team who are playing a huge role in the team. However, the team has a little problem with Bayern Munich's goalkeeper. Hope the coach of the team will solve this problem very well.
As usual, in Bundesliga, Bayern always becomes the best and hold the title. It seems that they don't have any other competitive clubs that can balance Bayern Munich in Bundesliga. Moreover Dortmund, they are falling currently.
so if you want to see if Bayern is exactly a very good club with a strong squad, watch them in UCL.
Even though Bayern Munich have lost their main goalkeeper who has been on the crossbar for many years, I believe it is not a big problem for them in this Bundesliga. As you said, Bayern Munich has no competitors that will make them have to work twice as hard for the title. Borussia Dortmund, which has been their main competitor, is now in an unfavorable situation for Borussia Dortmund.
Let's watch out for Bayern Munich's next match first, because I know Neuer's absence will be intensely felt by the team in their subsequent matches. Until then, I wouldn't say that the absence of a team's best goalkeeper is or will not be a problem for that club. No doubt, Dortmund is currently in an unfavorable condition, but other clubs have performed extremely well in the German Bundesliga this year, and they may likely be a problem to Bayern Munich. One must not be too sure of a meal until he has eaten it; Bayern has to work hard to annul the effect of Neuer's absence.
