Even though Bayern Munich failed to take advantage of the opportunities that existed, we should appreciate the role of the Hertha Berlin goalkeeper because he managed to make 7 saves in that match and it is only natural that Bayern Munich had a little trouble to win this match. Maybe if Hertha Berlin's defense was stronger then the match could have ended in a draw, but luckily Gnabry and Coman were able to take advantage of this situation and netted two goals against Hertha Berlin. Of course, many bettors made money through this easy match, but of course there were those who had doubts that Bayern Munich would fail to win again. 
Between Bayern's first and second goal i don't really know which is more classic. Bayern played the game at ease. Congratulations to them for making it to the top.
Am pretty sure Bayern munich will do all they can to maintain their position. As for Borussia Dortmund, they need to work very hard to also maintain their position because it will be so hard to beat Bayern munich. Their present formation and performance is a tough one.
