The Bundesliga is the most boring league among the five big leagues in Europe. Bayern Munich will do wonders again and their opponents have little chance of winning.
Freiburg is way above expectations in the league and in the Europa League. Currently, Bayer Leverkusen has attracted negative attention, but they will recover.
It's boring because only the same team is doing well and that's all in every season like Bayern Munich. But if for this season it is recognized or not recognized the Bundesliga has started to be a little different with the increase in the performance of teams such as Dortmund, Freiburg and Union Berlin which some people do not think that they can be good this season so that the boring things that have happened in the Bundesliga have started to disappear a little.
Even quality difference is still widened between these teams and Bayern Munich, but good thing is happening now few teams as you mention are competing with this giant and giving them good challenge which is positive development in Bundesliga and nothing happening like Ligue1 where still just two teams at top and no one near them for having tough challenge but here we will need some more development and consistency from these teams which will bring more interest and good entertainment for fans which are feeling not good just because of one teams hold.
Right now as Freiburg, Borussia Dortmund and Union Berlin giving challenge if they keep this momentum then surely we will be able to have some good end of this season not only one team is going to win league around six or seven weeks before end of season.
